iOS开发-摇一摇功能的实现

实现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

第一步

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

第二步

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

第三步

#pragma mark - ShakeToEdit 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>
    }
    
}
