iPhone加速度计更改灵敏度-可可触控
||
你好
我希望在用户移动设备时改变灵敏度。目前它还不是很敏感，我相信它是默认的。我希望它更加灵敏，因此当用户稍微摇动手机时，声音就会播放。
这是代码
谢谢
- (BOOL)canBecomeFirstResponder
{
return YES;
}
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
[self becomeFirstResponder];
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if(motion == UIEventSubtypeMotionShake)
{
NSString *path = [[NSBundle mainBundle] pathForResource:@\"whip\" ofType:@\"wav\"];
if (theAudio) [theAudio release];
NSError *error = nil;
theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:&error];
if (error)
NSLog(@\"%@\",[error localizedDescription]);
theAudio.delegate = self;
[theAudio play];
}
}

委婪绷冗诉
现在在您的实现中：实现委托方法：- (void)accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration { float x = acceleration.x; float y = acceleration.y; float b = acceleration.z; // here you can write simple change threshold logic // so you can call trigger your method if you detect the movement you\'re after }久坡
镀建啼
然后在您的委托回调中：- (void) accelerometer: (UIAccelerometer *) accelerometer didAccelerate: (UIAcceleration *) acceleration { // TODO add this acceleration to a list of accelerations and keep the most recent (perhaps 30) // TODO analyze accelerations and determine if a direction change occurred // TODO if it did, then a shake occurred! Clear the list of accelerations and perform your action }
