Ios 获取UIButton的x和y坐标

我有一个按钮叫“buttonPressed”。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
{

}

回答

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

听起来你想从动作的发送者那里得到X&Y。将sender参数附加到按钮点击方法，并找到sender的框架

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

哪个坐标？你想把它们送到哪里？谢谢。问题是：（UIButton*）我有（id）的地方。我没有看到这一教训
