触摸内部以获取UIImageView [英] Touch Up Inside for a UIImageView

问题描述

我正在尝试实现类似于 Touch Up Inside a UIButton 的触摸事件。我见过一些使用 touchesBegan：withEvent 的代码，但看起来我需要在屏幕上滑动一下手指。我其实只想触摸图片

I'm trying to implement touch event similar to a Touch Up Inside a UIButton. I've seen some codes using touchesBegan:withEvent but it looks I need to slide a bit my finger over the screen. I actually just want to touch in the image

代码：

- (void) touchesBegan:(NSSet*)touches withEvent:(UIEvent*)event {   
    NSLog(@"Image touched!");
}

问候！

推荐答案

您可以使用手势来触及 UIImageView 。

UITapGestureRecognizer *tapRecognizer = [[UITapGestureRecognizer alloc]
                         initWithTarget:self action:@selector(ClickEventOnImage:)];
        [tapRecognizer setNumberOfTouchesRequired:2];
        [tapRecognizer setDelegate:self];
        //Don't forget to set the userInteractionEnabled to YES, by default It's NO.
        myImageView.userInteractionEnabled = YES;
        [myImageView addGestureRecognizer:tapRecognizer];

实施 ClickEventOnImage 功能。

-(void) ClickEventOnImage:(id) sender
{

}
