iOS通过UISwitch控制摇一摇

- (IBAction)shakeNavi:(UISwitch *)sender {
 BOOL value = sender.on;
 // 保存UISwitch的开关状态
 [[NSUserDefaults standardUserDefaults] setObject:[NSNumber numberWithBool:value] forKey:@"switch_state"];
 if (value) {
  [[NSUserDefaults standardUserDefaults] setObject:@"shake" forKey:@"isShake"];
  [[NSUserDefaults standardUserDefaults] synchronize];// 同步
 } else {
  [[NSUserDefaults standardUserDefaults] setObject:@"notShake" forKey:@"isShake"];
  [[NSUserDefaults standardUserDefaults] synchronize];// 同步
 }
}

// 设置允许摇一摇功能
[UIApplication sharedApplication].applicationSupportsShakeToEdit = YES;
 //并让自己成为第一响应者
 [self becomeFirstResponder];

#pragma mark - 摇一摇相关方法
// 摇一摇开始摇动
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event {
 NSString *str = [[NSUserDefaults standardUserDefaults] objectForKey:@"isShake"];

 if ([str isEqualToString:@"shake"]) {
  NSLog(@"开始摇动");
  //播放震动
  AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
 }
 return;
}

// 摇一摇取消摇动
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event {
 NSLog(@"取消摇动");
 return;
}

// 摇一摇摇动结束
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event {

 NSString *str = [[NSUserDefaults standardUserDefaults] objectForKey:@"isShake"];

 if ([str isEqualToString:@"notShake"]) {
  return;
 }
 if (event.subtype == UIEventSubtypeMotionShake) { // 判断是否是摇动结束
  NSLog(@"结束摇动");
  // 在这里执行摇动结束需要执行的方法
 }
 return;
}

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
