iOS功能开发——摇一摇

使用iOS的摇一摇功能，只需要让当前Controller本身支持摇动，同时让它成为第一响应者即可。

- (void)viewDidLoad { 
    [super viewDidLoad]; 
    [[UIApplication sharedApplication] setApplicationSupportsShakeToEdit:YES]; 
    [self becomeFirstResponder]; 
    }

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

#pragma mark - 摇动手机之后的回调方法
- (void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    //检测到摇动开始
    if (motion == UIEventSubtypeMotionShake)
    {
      // your code
      NSLog(@"检测到摇动开始");
    }
}

- (void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    //摇动取消
    NSLog(@"摇动取消");
}

- (void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {
    //摇动结束
    if (event.subtype == UIEventSubtypeMotionShake)
    {
        // your code
        NSLog(@"摇动结束");
        AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);//振动效果 需要#import <AudioToolbox/AudioToolbox.h>
    }  
}
