ios创建多宫格界面方法（1）

iOS中，多宫格的界面很常见，实现的方法也有很多种，例如除了常见的UICollectionView方式，也还可以通过自定义一个UIView，在UIView中实现多宫格的创建，以下为我的工程中封装的多宫格创建代码，在此记录一下。

完整代码

1.自定义一个继承UIView的类JiugonggeView

//JiugonggeView.h文件中实现
@interface JiugonggeView : UIView
//将点击按钮的事件传回给上一层
@property (nonatomic, copy)void(^callBackTitle)(NSString *title);
//视图的初始化
- (instancetype)initWithFrame:(CGRect)frame andBtnTitleArray:(NSArray *)array;
@end

//JiugonggeView.m文件中实现
#define IMAGENAMED(imgName) [UIImage imageNamed:imgName]
@implementation JiugonggeView
{
    CGFloat rowFloat;
}
//视图初始化
- (instancetype)initWithFrame:(CGRect)frame andBtnTitleArray:(NSArray *)array
{
    self = [super initWithFrame:frame];
    if (self)
    {
        //创建按钮的边框
        rowFloat = 4.00;//这里表示行数为4
        for (NSInteger i = 0; i < rowFloat; i ++)
        {
            //每行列数为3
            for (NSInteger j = 0; j < 3; j ++)
            {
                CGFloat btnW =  frame.size.width/3.00;
                CGFloat btnH = frame.size.height/rowFloat-0.3;
                CGFloat  btnX = j*btnW;
                CGFloat btnY = I*btnH;
                UIView *backView = [[UIView alloc] initWithFrame:CGRectMake(btnX, btnY, btnW, btnH)];
                [backView.layer setBorderColor:RGB_HEX(0xe3e3e3, 1).CGColor];
                [backView.layer setBorderWidth:0.3];
                [self addSubview:backView];
            }
        }
        [self createBtn:array];
    }
    return self;
}
//创建按钮
- (void)createBtn:(NSArray *)array
{
    //计算行数
    NSInteger myCount = [array count]/3;
    if ([array count]%3 > 0)
    {
        myCount += 1;
    }
    //从数组中取标题的索引
    NSInteger index = 0;
    //行循环
    for (NSInteger i = 0; i <myCount; i ++)
    {
        //计算列数
        NSInteger num = 3;
        if (i == myCount-1 && [array count]%3 > 0)
        {
            num = [array count]%3;
        }
        //列循环
        for (NSInteger j = 0; j < num; j ++)
        {
            //设置按钮的位置参数
            CGFloat btnW =  self.frame.size.width/3.00;
            CGFloat btnH = self.frame.size.height/rowFloat;
            CGFloat  btnX = j*btnW;
            CGFloat btnY = I*btnH;
            //创建按钮
            UIButton *btn = [UIButton buttonWithType:UIButtonTypeCustom];
            [btn setFrame:CGRectMake(btnX, btnY, btnW, btnH)];
            [btn setBackgroundColor:[UIColor clearColor]];
            [btn addTarget:self action:@selector(btnFunction:) forControlEvents:UIControlEventTouchUpInside];
            [self addSubview:btn];
            //设置按钮中图片文字
            NSArray *ary = array[index];
            [btn setTitle:ary[1] forState:UIControlStateNormal];
            [btn.titleLabel setFont:[UIFont systemFontOfSize:14 weight:UIFontWeightLight]];
            [btn.titleLabel setNumberOfLines:0];
            [btn.titleLabel setTextAlignment:NSTextAlignmentCenter];
            [btn setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
            [btn setImage:IMAGENAMED(ary[0]) forState:UIControlStateNormal];
            //设置按钮中图片在上文字在下
            CGFloat offset = 14.0f;
            btn.titleEdgeInsets = UIEdgeInsetsMake(0, -btn.imageView.frame.size.width, -btn.imageView.frame.size.height-offset/2, 0);
            btn.imageEdgeInsets = UIEdgeInsetsMake(-btn.titleLabel.intrinsicContentSize.height-offset/2, 0, 0, -btn.titleLabel.intrinsicContentSize.width);
            //设置从数组中取标题的索引
            index ++;
        }
    }
}
//点击按钮
- (void)btnFunction:(UIButton *)sender
{
    if (self.callBackTitle)
    {
        self.callBackTitle(sender.titleLabel.text);
    }
}

2.在VC中调用

- (void)viewDidLoad
{
    [super viewDidLoad];
    [self createScrollView];
}
//创建视图
- (void)createScrollView
{
     NSArray *dataAry = @[@[@"res_ico_Report",@"按钮1"],@[@"oth_ico_app",@"按钮2"],@[@"oth_ico_dtc",@"按钮3"],@[@"res_ico_batterydataplayback",@"按钮4"],@[@"res_ico_dataplayback",@"按钮5"]];
    //创建功能按钮视图
    JiugonggeView *funcView = [[JiugonggeView alloc] initWithFrame:CGRectMake(0, 0, SCREEN_W, SCREEN_H) andBtnTitleArray: dataAry];
    [funcView setBackgroundColor:[UIColor clearColor]];
    [self.view addSubview:funcView];
    //点击按钮后的回调
    [funcView setCallBackTitle:^(NSString *title)
    {
        [self funcButtonClickAction:title];
    }];
}
//实现按钮方法
- (void)funcButtonClickAction:(NSString *)title
{
}
