UItapgestureRecognizer
全部标签 我是手势识别器的新手,所以这个问题可能听起来很傻:我正在将点击手势识别器分配给一堆UIView。在该方法中是否有可能找出其中哪些被以某种方式被点击,或者我需要使用屏幕上被点击的点来找出它?for(NSUIntegeri=0;i 最佳答案 用参数定义你的目标选择器(highlightLetter:)UITapGestureRecognizer*letterTapRecognizer=[[UITapGestureRecognizeralloc]initWithTarget:selfaction:@selector(highlightLe

在使用UIGestureRecognizers时,我如何知道在哪个subview上发生了事件?根据文档:Agesturerecognizeroperatesontoucheshit-testedtoaspecificviewandallofthatview’ssubviews.据我所知,'view'属性是Theviewthegesturerecognizerisattachedto.这将是父View。 最佳答案 这将在事件的位置找到最里面的后代View。(请注意,如果该subview有任何交互式内部私有(private)孙子,则此代

如何在UIScrollView中检测触摸点?触摸委托(delegate)方法不起作用。 最佳答案 设置点击手势识别器:UITapGestureRecognizer*singleTap=[[UITapGestureRecognizeralloc]initWithTarget:selfaction:@selector(singleTapGestureCaptured:)];[scrollViewaddGestureRecognizer:singleTap];你会接触到:-(void)singleTapGestureCaptured:(U
