ios - 旋转UIButton并保留其大小

我正在尝试旋转形状为正方形(65 x 65)的按钮。旋转它们后，按钮会更改其大小。有什么办法可以旋转并保持尺寸？

代码:

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];

self.stealthButton.transform = CGAffineTransformMakeRotation(radians);
self.recButton.transform = CGAffineTransformMakeRotation(radians);
self.toggleButton.transform = CGAffineTransformMakeRotation(radians);
[UIView commitAnimations];

最佳答案

尝试这样可能会对您有所帮助，

CABasicAnimation *fullRotation = [CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    fullRotation.fromValue = [NSNumber numberWithFloat:0];
    fullRotation.toValue = [NSNumber numberWithFloat:((360*M_PI)/180)];
    fullRotation.duration = 1;
    fullRotation.repeatCount = 1;
    [button.layer addAnimation:fullRotation forKey:@"360"];

在您的项目中添加以下框架。

#import <QuartzCore/QuartzCore.h>
#import "QuartzCore/CALayer.h"
