    Autolayout纯代码布局九宫格

    单行固定间隔排列:


    固定间隔
    -(void)buildViews {
        NSMutableArray *array = [NSMutableArray array];
        for (NSInteger i=0; i < 4; i++) {
            UIView *subView = [UIView new];
            subView.backgroundColor = [UIColor orangeColor];
            [self.view addSubview:subView];
            
            [array addObject:subView];
        }
        
        [self vfHLayoutViews:array  withFixedSpacing:20 leadSpacing:20 tailSpacing:20];
        [self vfVLayoutViews:array  withHeight:100 topSpacing:100];
        
    }
    

    水平布局设置

    - (void)vfHLayoutViews:(NSArray*)views  withFixedSpacing:(CGFloat)fixedSpace leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing{
        UIView *lastView = nil;
        UIView *supV = nil;
        NSInteger cout = views.count;
        if (cout < 1) {
            NSAssert(cout>0,@"views to distribute need to least one");
            return;
        }
        for (int i = 0; i < cout; i++) {
            UIView *subView = views[i];
            if (subView.translatesAutoresizingMaskIntoConstraints) {
                subView.translatesAutoresizingMaskIntoConstraints = NO;
            }
        
            if (lastView) {
                if (i==cout-1) {

                }
                
            }else{
                supV = subView.superview;
                if (!supV) {
                    NSCAssert(NO, @"no found the view of superview");
                    return;
                }
                if (cout == 1) {

                }
                
            }
            
            lastView = subView;
        }
        
    }
    
    

    垂直布局设置

    - (void)vfVLayoutViews:(NSArray*)views withHeight:(CGFloat)height topSpacing:(CGFloat)topSpacing{
        NSInteger cout = views.count;
        UIView *supV = nil;

            UIView *subView = views[i];
            if (subView.translatesAutoresizingMaskIntoConstraints) {
                subView.translatesAutoresizingMaskIntoConstraints = NO;
            }
            if (!supV) {
                supV = subView.superview;
                if (!supV) {
                    NSCAssert(NO, @"no found the view of superview");
                    return;
                }
            }

        }
    }
    

    固定宽度设置:

    -(void)buildViewsFixedWidth{
        NSMutableArray *array = [NSMutableArray array];
        for (NSInteger i=0; i < 5; i++) {

            subView.backgroundColor = [UIColor colorWithHue:( arc4random() % 256 / 256.0 )

                                                 brightness:( arc4random() % 128 / 256.0 ) + 0.5
                                                      alpha:1];
            [self.view addSubview:subView];
            
            [array addObject:subView];
        }
        
        [self vfHLayoutViews:array  withFixedItemWidth:50 leadSpacing:20 tailSpacing:20];
        [self vfVLayoutViews:array  withHeight:100 topSpacing:100];
    }
    

    水平布局

    - (void)vfHLayoutViews:(NSArray*)views  withFixedItemWidth:(CGFloat)fixedWidth leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing{

        NSInteger cout = views.count;
        if (cout < 1) {

                }else{
                    //
                    CGFloat offset = (1-(i/((CGFloat)cout-1)))*(fixedWidth+leadSpacing)-i*tailSpacing/(((CGFloat)cout-1));
                    
                    [supV addConstraint:[NSLayoutConstraint constraintWithItem:subView attribute:NSLayoutAttributeWidth relatedBy:NSLayoutRelationEqual toItem:lastView attribute:NSLayoutAttributeWidth multiplier:1.0 constant:0]];
                    [supV addConstraint:[NSLayoutConstraint constraintWithItem:subView attribute:NSLayoutAttributeRight relatedBy:NSLayoutRelationEqual toItem:supV attribute:NSLayoutAttributeRight multiplier:i/((CGFloat)cout-1) constant:offset]];
                    
                }
                
            }else{
                supV = subView.superview;
                if (!supV) {
                    NSCAssert(NO, @"no found the view of superview");
                    return;
                }
                if (cout == 1) {
                    [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[subView(fixedWidth)]" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"fixedWidth":@(fixedWidth)} views:@{@"subView":subView}]];
                    [supV addConstraint:[NSLayoutConstraint constraintWithItem:subView attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:supV attribute:NSLayoutAttributeCenterX multiplier:1.0 constant:0]];
                }else{
                    [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-leadSpacing-[subView(fixedWidth)]" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"leadSpacing":@(leadSpacing),@"fixedWidth":@(fixedWidth)} views:@{@"subView":subView}]];
                }
            }
            
            lastView = subView;
            
        }
        
    }
    
    

    垂直布局和上面一样

    下面开始布局有多行的九宫格:


    9C7FE46A-1BFB-40DA-89FF-7B8F86C040FC.png
    -(void)buildViewsCells {
        
        UIView *view = [UIView new];
        view.translatesAutoresizingMaskIntoConstraints = NO;
        view.backgroundColor = [UIColor yellowColor];
        [self.view addSubview:view];
        
        
        NSMutableArray *array = [NSMutableArray array];
        for (NSInteger i=0; i < 8; i++) {
            UILabel *subView = [UILabel new];
            subView.backgroundColor = [UIColor orangeColor];
            subView.textAlignment = NSTextAlignmentCenter;
            subView.text = [NSString stringWithFormat:@"%ld",i];
            [view addSubview:subView];
            
            [array addObject:subView];
        }
        
       [self layoutViews:array withColumns:3 hFixedSpacing:10 vFixedSpacing:20 fixedItemHeight:0 topSpacing:10 bottomSpacing:10 leadSpacing:10 tailSpacing:10];
        
        [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-20-[view]-20-|" options:0 metrics:@{} views:@{@"view":view}]];
        [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-100-[view]-200-|" options:0 metrics:@{} views:@{@"view":view}]];
        
        /*
         //动态获取自适应高度
        UIView *lastView = [self layoutViews:array withColumns:3 hFixedSpacing:10 vFixedSpacing:20 fixedItemHeight:100 topSpacing:10 bottomSpacing:10 leadSpacing:10 tailSpacing:10];
        
        [self.view addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-20-[view]-20-|" options:0 metrics:@{} views:@{@"view":view}]];
        [self.view addConstraint:[NSLayoutConstraint constraintWithItem:view attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:self.view attribute:NSLayoutAttributeTop multiplier:1.0 constant:100]];
        [self.view addConstraint:[NSLayoutConstraint constraintWithItem:view attribute:NSLayoutAttributeBottom relatedBy:NSLayoutRelationEqual toItem:lastView attribute:NSLayoutAttributeBottom multiplier:1.0 constant:10]];
        */
        
    }
    

    刚开始都在一个方法里做的水平和垂直布局:

    //如果高度大于0,则按照固定高度布局
    - (UIView *)vfLayoutViews:(NSArray*)views withColumns:(NSInteger)columnsCout hFixedSpacing:(CGFloat)hFixedSpace vFixedSpacing:(CGFloat)vFixedSpace  fixedItemHeight:(CGFloat)fixedHeight topSpacing:(CGFloat)topSpacing bottomSpacing:(CGFloat)bottomSpacing leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing {

        UIView *rowFristView = nil;
        UIView *supV = nil;
        NSInteger cout = views.count;
        if (cout < 1) {
            NSAssert(cout>0,@"views to distribute need to least one");
            return nil;
        }
        
        NSInteger residue = columnsCout - cout%columnsCout;
        NSMutableArray *newViews = [NSMutableArray arrayWithArray:views];
        for (int k = 0; k<residue; k++) {
            UIView *tempView = [UIView new];
            tempView.backgroundColor = [UIColor clearColor];
            [newViews addObject:tempView];
        }
        cout = newViews.count;
        NSInteger totalRows = cout/columnsCout;
        
        for (int i = 0; i < cout; i++) {

            if (subView.translatesAutoresizingMaskIntoConstraints) {

            }
            NSInteger row = i/columnsCout;
            NSInteger column = i%columnsCout;
            if (lastView) {
                if (!subView.superview) {
                    [supV addSubview:subView];
                }
                if (columnsCout == 1) {

                }else{

                        [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:[lastView]-hFixedSpace-[subView(==lastView)]-tailSpacing-|" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"hFixedSpace":@(hFixedSpace),@"tailSpacing":@(tailSpacing)} views:@{@"lastView":lastView,@"subView":subView}]];
                        
                    }else{
                        if (column == 0) {
                            [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-leadSpacing-[subView]" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"leadSpacing":@(leadSpacing)} views:@{@"subView":subView}]];
                        }else{

                        }
                        
                        
                    }

                        }else{
                            [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[rowFristView]-vFixedSpace-[subView(==rowFristView)]-bottomSpacing-|" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"vFixedSpace":@(vFixedSpace),@"bottomSpacing":@(bottomSpacing)} views:@{@"subView":subView,@"rowFristView":rowFristView}]];
                        }
                        
                    }else{
                        
                        [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:[rowFristView]-vFixedSpace-[subView(==rowFristView)]" options:NSLayoutFormatDirectionLeftToRight metrics:@{@"vFixedSpace":@(vFixedSpace)} views:@{@"subView":subView,@"rowFristView":rowFristView}]];
                        
                    }
                    rowFristView = subView;
                    
                }else{
                    
                    [supV addConstraint:[NSLayoutConstraint constraintWithItem:subView attribute:NSLayoutAttributeTop relatedBy:NSLayoutRelationEqual toItem:lastView attribute:NSLayoutAttributeTop multiplier:1.0 constant:0]];
                    [supV addConstraint:[NSLayoutConstraint constraintWithItem:subView attribute:NSLayoutAttributeHeight relatedBy:NSLayoutRelationEqual toItem:lastView attribute:NSLayoutAttributeHeight multiplier:1.0 constant:0]];
                    
                }
                
                
            }else{
                supV = subView.superview;
                if (!supV) {
                    NSCAssert(NO, @"no found the view of superview");
                    return nil;
                }
                
                if (columnsCout == 1) {
                    [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-leadSpacing-[subView]-tailSpacing-|" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"leadSpacing":@(leadSpacing),@"tailSpacing":@(tailSpacing)} views:@{@"subView":subView}]];
                }else{
                    [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"H:|-leadSpacing-[subView]" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"leadSpacing":@(leadSpacing)} views:@{@"subView":subView}]];
                }
                
                if (fixedHeight > 0) {
                    [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-topSpacing-[subView(fixedHeight)]" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"topSpacing":@(topSpacing),@"fixedHeight":@(fixedHeight)} views:@{@"subView":subView}]];
                }else{
                    [supV addConstraints:[NSLayoutConstraint constraintsWithVisualFormat:@"V:|-topSpacing-[subView]" options:NSLayoutFormatDirectionLeadingToTrailing metrics:@{@"topSpacing":@(topSpacing)} views:@{@"subView":subView}]];
                }
                
                rowFristView = subView;
            }
            
            lastView = subView;
            
        }
        
        return lastView;
        
    }
    

    这样看起来一个方法里代码太多了,于是把水平布局和垂直布局分离开来:

    - (UIView *)layoutViews:(NSArray*)views withColumns:(NSInteger)columnsCout hFixedSpacing:(CGFloat)hFixedSpace vFixedSpacing:(CGFloat)vFixedSpace  fixedItemHeight:(CGFloat)fixedHeight topSpacing:(CGFloat)topSpacing bottomSpacing:(CGFloat)bottomSpacing leadSpacing:(CGFloat)leadSpacing tailSpacing:(CGFloat)tailSpacing {
        
        NSInteger cout = views.count;
        if (cout < 1) {
            NSAssert(cout>0,@"views to distribute need to least one");
            return nil;
        }
        
        NSInteger residue = columnsCout - cout%columnsCout;
        NSMutableArray *newViews = [NSMutableArray arrayWithArray:views];
        for (int k = 0; k<residue; k++) {
            UIView *tempView = [UIView new];
            tempView.backgroundColor = [UIColor clearColor];
            [newViews addObject:tempView];
        }
        
        zj_horizontalLayout(newViews, columnsCout, leadSpacing, tailSpacing, hFixedSpace);
        zj_verticalLayout(newViews, columnsCout, fixedHeight, topSpacing, bottomSpacing, vFixedSpace);
        
        return [newViews lastObject];
        
    }
    

    水平布局方案:

    static void zj_horizontalLayout(NSArray *views, NSInteger columnsCout, CGFloat leadSpacing, CGFloat tailSpacing, CGFloat hFixedSpace) {
        UIView *lastView = nil;
        UIView *supV = nil;
