uibutton - 如何找出用户触摸图像的次数

Question

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

如果我有四个不同的按钮，您如何知道用户何时触摸某个按钮以及触摸了多少次。

Answer 1

我很喜欢 C#，所以如果我错了，请原谅我，但是当用户点击图像时，你不能只增加一个整数，那么如果你想知道点击量，你会看这个整数吗？

Answer 2

what you will have to do is take one integer in.h file then in .m file write touchesbegan method like below.

  - (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch *touch = [[event allTouches] anyObject];
   CGPoint touchlocation = [touch locationInView:self.view];
  if([touch isKindOfClass:[UIImage class]])
  {
     myInt++;//your global integer....
  }
}

let me know it is working or not!!!

Happy Coding!!!!

试试用这个..

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

    // ----------you can find using tag and first set button's tag in xib ------
    if(touch.view.tag == btnRed.tag)
    {
       redTouch++:
    }
}
