ios開發之xcode載入圖片點擊事件，圖片帶參數

clickx 作為一個方法被調用，表示當你點擊圖片的時候出發這個方法，這個方法可以自己隨便寫比如abc,clicky

代碼如下

複製代碼

- (IBAction)test:(id)sender {     UIImageView *imageView =[[UIImageView alloc]initWithFrame:CGRectMake(100, 100, 200, 200)];     imageView.image=[UIImage imageNamed:@"22.png"];     imageView.userInteractionEnabled = YES;     [imageView setTag:2];//為了帶個參數過去     UITapGestureRecognizer *singleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(clickx:)];     [imageView addGestureRecognizer:singleTap];     //[singleTap release];     [self.view addSubview:imageView]; }

UITapGestureRecognizer 帶過來的參數 gesture 將索引值tag給傳遞過來

代碼如下	複製代碼
- (IBAction)clickx:(id)sender,UITapGestureRecognizer *gesture{    UIView *temView = [gesture view];     NSInteger temIndex = temView.tag;     NSLog(@"aaaa%d",temIndex); }
