蘋果開發之iOS 搖一搖動畫

微信的搖一搖動畫效果看起來很棒，這裡是類似的搖一搖動畫效果，程式碼範例：

代碼如下

複製代碼

#pragma mark - 搖一搖 - (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {     if (motion == UIEventSubtypeMotionShake) {         AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); //震動效果         [self shakeView:phoneImgView];  //這裡的phoneImgView是需要搖動效果的圖片控制項     } } #pragma mark - 動畫 -(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];         }     }]; }

註：需要震動效果時，要匯入AudioToolbox.framework，然後匯入標頭檔”AudioToolbox/AudioToolbox.h”，實現的搖一搖動畫效果看起來還不錯，可以在自己的工程裡試一試。
