获取UIButton的x和y坐标

Question

我有一个名为“buttonPressed”的按钮。当我按下按钮时，我需要找到该按钮的x和y坐标。你有什么想法可以帮助我吗？

    UIButton *circleButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
    circleButton.frame = rect;
    circleButton.layer.cornerRadius = 8.0f;
    [circleButton addTarget:self
                     action:@selector(buttonPressed:)
           forControlEvents:UIControlEventTouchUpInside];
    [self addSubview:circleButton];

-(void)buttonPressed:(id)sender
{

}

答案

     - (IBAction)buttonPressed:(UIButton *)sender
     {
       CGPoint coordinates = sender.frame.origin;
       CGFloat x = coordinates.x;
       CGFloat y = coordinates.y;
     }

Answer 1

听起来你想要X＆amp; Y关闭了动作的发送者。将发件人参数附加到按钮点按方法，然后找到发件人的框架。

- (IBAction)buttonTapped:(UIButton *)sender
{
    CGPoint coordinates = sender.frame.origin;
}
