单击直接查看时，ios locationInView无法显示正确的日志

Question

我觉得很奇怪，我有黑暗视图（darkScreenView）和绿色视图。

我使用

 -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
 {
     UITouch *touch = [[event allTouches] anyObject];
     CGPoint touchViewPoint = [touch locationInView:touch.view];

      NSLog(@"[self.darkScreenView pointInside:touchViewPoint withEvent:event]:%d",[self.darkView pointInside:touchViewPoint withEvent:event]);
 }

当我点击暗视图或绿色视图时，

日志仍显示1.为什么？

我点击绿色视图应显示log 0，但我仍然得到日志结果1。

我正在使用xcode 6.3.1。

有谁知道这种情况有什么问题？

谢谢〜

Answer 1

尝试触摸不同的观点..

-(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
 {
  UITouch *touch = [[event allTouches] anyObject];
  if (touch.view==GREEN_VIEW)
  {
    //Write your code for green view here
  }
  else if(touch.view==DARK_VIEW)
  {
    //Write your code for dark view here
  }
}

Answer 2

您的touchViewPoint的位置是相对于触摸的视图。因此，获取相对于self.darkView的位置，如下所示。

Answer 3

以下是您所指的View的问题更改。

-(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
 {
     UITouch *touch = [[event allTouches] anyObject];
     CGPoint touchViewPoint = [touch locationInView:darkView];   <----- Problem

      NSLog(@"[self.darkScreenView pointInside:touchViewPoint withEvent:event]:%d",[self.darkView pointInside:touchViewPoint withEvent:event]);
 }

Answer 4

这将有效

UITouch *touch = [[event allTouches] anyObject];
    CGPoint touchViewPoint = [touch locationInView:touch.view];
    CGPoint  pointOfDarkView = [touch.view convertPoint:touchViewPoint toView:self.darkview];
    NSLog(@"[self.darkScreenView pointInside:touchViewPoint withEvent:event]:%d",[self.darkview pointInside:pointOfDarkView withEvent:event]);

您的问题：

touchViewPoint相对于touch.view坐标

您必须先将点转换为 darkview坐标，然后才能使用pointInside:pointOfDarkView
