iOS開發中實現搖一搖並震動

 首先導入AudioToolbox.framework :project ->TARGETS ->General ->Linked Frameworks and Libraries

注釋寫的比較清晰,直接上代碼了

#import <AudioToolbox/AudioToolbox.h> 

label是從sb中隨便拖過來方便搖后回調

@property (strong, nonatomic) IBOutlet UILabel *label;

- (void)viewDidLoad {
    [super viewDidLoad];
    //  支持搖一搖  此處應該寫在AppDelegate中,為粘貼代碼方便寫在這里
    [[UIApplication sharedApplication] setApplicationSupportsShakeToEdit:YES];
    //  讓此控制器成為第一響應者
    [self becomeFirstResponder];
    
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [self resignFirstResponder];
}

重寫下面方法即可搖動回調

//  開始搖動
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    NSLog(@"開始搖動");
    [self animation];
}


- (void)animation {
    CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"position"];
    anim.fromValue = [NSValue valueWithCGPoint:CGPointMake(100, 50)];
    anim.toValue = [NSValue valueWithCGPoint:CGPointMake(100, 500)];
    
    anim.removedOnCompletion = NO;
    anim.duration = 1.0f;
    anim.fillMode = kCAFillModeForwards;
    anim.delegate = self;
    //  隨便拖過來的一個label測試效果
    [self.label.layer addAnimation:anim forKey:nil];
}

//  結束搖動
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    if (event.type == UIEventSubtypeMotionShake ) {
        NSLog(@"搖動結束");
        [self shakeshake];
    }
}

//  搖動結束后執行震動
- (void)shakeshake {
　　// 震動
    AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}

完事,so easy
