我知道,这是一个很常见的问题,但所有的每一个网站上的答案不工作!如果你还是不明白我的意思,那么也许这行代码将有助于您理解。


- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [[event allTouches] anyObject];
    CGPoint location = [touch locationInView:self.view];
    if (touch.view == nextbutton)
        [self performSelector:@selector(next)];
    if (touch.view == prevbutton)
        [self performSelector:@selector(previous)];
    if (touch.view == moreoptionsbutton)
        [self performSelector:@selector(moresettings)];
}

这不,当你触摸nextbutton, prevbutton, and more optionsbutton,这是顺便说一下UIImageViews做任何事情。我一直在使用isEqual:代替==也尝试过,但还没有任何解决。任何建议?

有帮助吗?

解决方案

您必须设置userinteractionEnabled = YES您所有的UIImageViews否则他们将不会收到触摸事件。也改变了行:

 UITouch *touch = [[event allTouches] anyObject];

 UITouch *touch = [touches anyObject];

其他提示

我创建了一个检查,以确保它我希望之前将被点击的视图。

if( [touch.view isKindOfClass:[Custom class]] ){
    CGPoint touchPoint = [touch locationInView:self.view];

    if( CGRectContainsPoint( self.customClassOne.frame, touchPoint )
       || CGRectContainsPoint( self.customClassTwo.frame, touchPoint ) ){
        [self touchOnCustomClass];
    }
}
