我想在连接开始的时候轮换UIButton,希望在连接中断时停止轮换。
因此,我的问题是,如何在UIButton开始或停止轮换。
我采用以下轮任守则。
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:5.0];
// (180 * M_PI) / 180 == M_PI, so just use M_PI
btn.transform = CGAffineTransformMakeRotation(M_PI);
[UIView commitAnimations];
您可以通过打电话<条码>删除<条码>。
[btn.layer removeAllAnimations];
确保在接触层特性之前进口QuartzCore,否则你会得到警告。
#import <QuartzCore/QuartzCore.h>
不断使用
[UIView setAnimationRepeatCount:5000];
