单独使用collectionCell视图

偶然间在别人工程中看到的，方法很简单下面就让我来给大家说下 简单实现使用collectionCell 创建等同于view的视图

用法

#define SCREEN_WIDTH  [UIScreen mainScreen].bounds.size.width
#define SCREEN_HEIGHT  [UIScreen mainScreen].bounds.size.height
#define floatByScreenWidth(a) ((a)/320.0)*SCREEN_WIDTH

1.自定义collectionCell 添加你需要的属性
（比如添加一个图片 后者标题） 这里不再说

2.自定义一个view 声明一个方法

- (void)setView; // 声明一个方法

- (void)setView { // 实现方法
    for (int i = 0;  i < 8; i++) { // 需要创建几个视图
        // 读取cell 属性复制 添加点击事件 计算坐标
            MyCollectionCell *cell = [[[NSBundle mainBundle]loadNibNamed:@"MyCollectionCell" owner:self options:nil]lastObject];
            cell.backgroundColor = [UIColor colorWithRed:arc4random()%255/255.0 green:arc4random()%255/255.0 blue:arc4random()%255/255.0 alpha:arc4random()%255/255.0];
            cell.nametitle.text = [NSString stringWithFormat:@"第%dcell",i];
            UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc]init];
            [tap addTarget:self action:@selector(ClickVideoSites:)];
            cell.tag = i+1;
            tap.view.tag = i+1;
            [cell addGestureRecognizer:tap];
            
            int x = i/8;
            if (x<4) {
                cell.frame = [self setFrameBynum:i andPage:x];
            }else{
                cell.frame = [self setFrameBynum:i andPage:x];
            }
            [self addSubview:cell];  // self 即是自定义view视图
        }
    }
 }
 
 //布局cell的位置
- (CGRect)setFrameBynum:(int)num andPage:(int)page
    {
        CGFloat length = floatByScreenWidth(74);
        CGFloat height = length/74*85;
        CGFloat width = (SCREEN_WIDTH-4*length)/5;
        
        if (num  <  4) {
            return CGRectMake(width + page * SCREEN_WIDTH + (length+width)*num, 0, length, height);
        }
        else
            return CGRectMake(width + page * SCREEN_WIDTH + (length+width)*(num-4),height + 10, length, height);
    }

3.Controller里面使用

    MyView * _myView = [[MyView alloc]initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, SCREEN_HEIGHT)];
    [_myView setView];
    [self.view addSubview:_myView];

class XYNoDataView: UIView {
    
    var nodataView: XYAddressMyFriendNoDataCell?
    private func setup() {
        
        self.backgroundColor = #colorLiteral(red: 0.9490196078, green: 0.9607843137, blue: 0.968627451, alpha: 1)
        let rect = CGRect(x: 0, y: 68, w: UIScreen.main.bounds.size.width, h: 240)
        let nodataView = Bundle.main.loadNibNamed("XYAddressMyFriendNoDataCell", owner: nil, options: nil)?.first as! XYAddressMyFriendNoDataCell
        nodataView.frame = rect
        self.addSubview(nodataView)
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        setup()
    }
    
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setup()
    }
}

到这里已经实现自定义collectioncell视图的使用，希望帮到你们，谢谢
