苹果开发之iOS 摇一摇动画

微信的摇一摇动画效果看起来很棒，这里是类似的摇一摇动画效果，代码示例：

代码如下

复制代码

#pragma mark - 摇一摇
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
    if (motion == UIEventSubtypeMotionShake) {
        AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); //震动效果
        [self shakeView:phoneImgView]; //这里的phoneImgView是需要摇动效果的图片控件
    }
}
#pragma mark - 动画
-(void)shakeView:(UIView*)viewToShake
{
    CGFloat t = 14.0;
    CGAffineTransform translateRight = CGAffineTransformTranslate(CGAffineTransformIdentity, t, 0.0);
    CGAffineTransform translateLeft = CGAffineTransformTranslate(CGAffineTransformIdentity, -t, 0.0);
    viewToShake.transform = translateLeft;

    [UIView animateWithDuration:0.08 delay:0.0 options:UIViewAnimationOptionAutoreverse|UIViewAnimationOptionRepeat animations:^{
        [UIView setAnimationRepeatCount:5.0];
        viewToShake.transform = translateRight;
    } completion:^(BOOL finished){
        if(finished){
            [UIView animateWithDuration:0.08 delay:0.0 options:UIViewAnimationOptionBeginFromCurrentState animations:^{
                viewToShake.transform =CGAffineTransformIdentity;
            } completion:NULL];
        }
    }];
}

注：需要震动效果时，要导入AudioToolbox.framework，然后导入头文件”AudioToolbox/AudioToolbox.h”，实现的摇一摇动画效果看起来还不错，可以在自己的工程里试一试。
