IOS中实现设备摇动检测
这些方法都是在网上看到的，我自己经过测试的就这2种；
1.UIWindow（已测试）
- (void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (motion == UIEventSubtypeMotionShake )
{
//这里可以促发系统震动，或者发送一个通知，进行相应的处理
}
}
- (void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
}
2. UIViewController（继承自UIResponder - 已测试）
-(BOOL)canBecomeFirstResponder {
returnself.shakeSyncIsOn;//这里是self拥有的一个变量，通过这个变量来设置为第一个激活的responder,只有这个方法返回为true时才可以摇动
}
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
if ([selfcanBecomeFirstResponder]==YES)
{
NSLog(@”becomeFirstResponder:YES”);
//下面这句代码，不一定非得写到viewDidLoad或者applicationDidFinishLaunch中,这里也可以
[[UIApplicationsharedApplication] setApplicationSupportsShakeToEdit:YES];
[selfbecomeFirstResponder];
}
else{
NSLog(@”becomeFirstResponder:NO”);
}
}
- (void)viewWillDisappear:(BOOL)animated {
[selfresignFirstResponder];
[super viewWillDisappear:animated];
}
#pragma mark -
#pragma mark - shakeToSync: UIResponder support motion
//开始摇动检测
-(void)motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@”====== Shake Begins =======”);
}
-(void)motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
NSLog(@”======= Shake Canceled =======”);
}
-(void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (motion == UIEventSubtypeMotionShake)
{
NSLog(@”======== Shake End ========”);
//这里可以添加震动反馈，或者发送一个通知
//AudioToolBox.framework
//_#import “AudioToolbox/AudioToolbox.h”�_�
AudioServicesPlaySystemSound(kSystemSoundID_Vibrate);
}
}
