通过tag获取控件，实现image数组添加点击事件

最近小白项目里遇到一些问题，让小白很抓狂吖！其中一个就是如何通过tag获取控件，实现image数组添加点击事件的问题，其实不难的，可是小白只知道UIBtton数组用tag值来区分控件实现点击，还有就是单张imageView用UITapGestureRecognizer来实现点击方法，

//添加单击手势

UITapGestureRecognizer* singleRecognizer;

singleRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(handlePanFrom:)];

singleRecognizer.numberOfTapsRequired = 1;

[imageView addGestureRecognizer:singleRecognizer];

imageView.userInteractionEnabled=YES;

但现在的问题是imageArray,小白解决方法是：

UICollectionViewCell的.h文件

@property (strong, nonatomic) IBOutletCollection(UIImageView) NSArray *imageArray;

@property(nonatomic,copy)void(^image0Block)();

@property(nonatomic,copy)void(^image1Block)();

@property(nonatomic,copy)void(^image2Block)();

@property(nonatomic,copy)void(^image3Block)();

@property(nonatomic,copy)void(^image4Block)();

@end

UICollectionViewCell的.m文件

UIButton *btn0 = [self.imageArray[0] viewWithTag:0];

[btn0 bk_whenTapped:^{

if (self.image0Block) {

self.image0Block();

}

}];

UIButton *btn1 = [self.imageArray[1] viewWithTag:1];

[btn1 bk_whenTapped:^{

if (self.image1Block) {

self.image1Block();

}

}];

UIButton *btn2 = [self.imageArray[2] viewWithTag:2];

[btn2 bk_whenTapped:^{

if (self.image2Block) {

self.image2Block();

}

}];

UIButton *btn3 = [self.imageArray[3] viewWithTag:3];

[btn3 bk_whenTapped:^{

if (self.image3Block) {

self.image3Block();

}

}];

UIButton *btn4 = [self.imageArray[4] viewWithTag:4];

[btn4 bk_whenTapped:^{

if (self.image4Block) {

self.image4Block();

}

}];

ViewController.m

cell.image0Block = ^{NSLog(@"图0被点击了");};

cell.image1Block = ^{NSLog(@"图1被点击了");};

cell.image2Block = ^{NSLog(@"图2被点击了");};

cell.image3Block = ^{NSLog(@"图3被点击了");};

cell.image4Block = ^{NSLog(@"图4被点击了");};
