Question

有人可以告诉我如何在触摸时缩放UIButton吗？该按钮应该按比例放大10％。

提前致谢！

Answer 1

呼叫

button.transform = CGAffineTransformMakeScale(1.1,1.1);

按下按钮处理程序。

或者如果你想用动画进行缩放：

[UIView beginAnimations:@"ScaleButton" context:NULL];
[UIView setAnimationDuration: 0.5f];
button.transform = CGAffineTransformMakeScale(1.1,1.1);
[UIView commitAnimations];

Answer 2

要完成答案，按钮缩放（和重置）可以放在如下方法中：

// Scale up on button press
- (void) buttonPress:(UIButton*)button {
    button.transform = CGAffineTransformMakeScale(1.1, 1.1);
    // Do something else
}

// Scale down on button release
- (void) buttonRelease:(UIButton*)button {
    button.transform = CGAffineTransformMakeScale(1.0, 1.0);
    // Do something else
}

与按钮的事件相关联如下：

[btn addTarget:self action:@selector(buttonPress:) forControlEvents:UIControlEventTouchDown];
[btn addTarget:self action:@selector(buttonRelease:) forControlEvents:UIControlEventTouchUpInside];
[btn addTarget:self action:@selector(buttonRelease:) forControlEvents:UIControlEventTouchUpOutside];

注1：将CGAffineTransformMakeScale值设置为1.0并不会使它们保持更改的值（即，它不会将1.1乘以1.0），而是将其设置回对象的原始比例。

注2：不要忘记选择器中的冒号:，因为它允许将发件人作为参数传递给接收方法。在这种情况下，我们的方法接收一个UIButton，并在接口（.h文件）中声明为。

Answer 3

这是我使用的

-(IBAction)heartButtonTapped:(UIButton*)sender {
    [sender setSelected:!sender.isSelected];


    [UIView animateWithDuration:0.6 delay:0.0 options:UIViewAnimationOptionAutoreverse animations:^{
        sender.transform = CGAffineTransformMakeScale(1.5,1.5);
    } completion:^(BOOL finished) {
        sender.transform = CGAffineTransformMakeScale(1,1);
    }];
}

Answer 4

稍微修改了@ ibm123的代码，避免了突然调整大小的问题。

- (IBAction) buttonTapAction:(UIButton *) sender {
[self animatePressedDown:sender duration:0.6 zoom:1.5];

}

- (void)animatePressedDown:(UIButton *) sender duration:(double) t zoom:(double) zoomX {
[UIView animateWithDuration:t delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^{
    sender.transform = CGAffineTransformMakeScale(zoomX,zoomX);
} completion:^(BOOL finished) {
    [UIView animateWithDuration:t delay:0.0 options:UIViewAnimationOptionCurveEaseOut animations:^{
        sender.transform = CGAffineTransformMakeScale(1,1);
    } completion:nil];
}];

}

Answer 5

夫特：

button.transform = CGAffineTransform.init(scaleX: 1.0, y: 1.0)

Answer 6

::v-deep .user {
  ...
}

要使其更像本机UIButton行为，我更喜欢在子类中使用touchesBegun和touchesEnded方法：

class BaseButton: UIButton {
    
    override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesBegan(touches, with: event)
        UIView.animate(withDuration: 0.3) {
            self.transform = CGAffineTransform(scaleX: 1.1, y: 1.1)
            self.titleLabel?.alpha = 0.7
        }
    }
    
    override func touchesEnded(_ touches: Set<UITouch>, with event: UIEvent?) {
        super.touchesEnded(touches, with: event)
        UIView.animate(withDuration: 0.3) {
            self.transform = .identity
            self.titleLabel?.alpha = 1
        }
    }
    
}
