IOS 摇一摇功能

设备摇动检测的两种方法简单的记录下

方法一

首先在delegate中添加

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

// Override point for customization after application launch

//添加检测晃动

application.applicationSupportsShakeToEdit = YES;

}

其次在需要检测的ViewController中添加

//检测手机晃动

-(BOOL)canBecomeFirstResponder

{

return YES;

}

- (void)viewWillDisappear:(BOOL)animated {

[self resignFirstResponder];

[super viewWillDisappear:animated];

}

- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event

{

if (motion == UIEventSubtypeMotionShake)

{

UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"提示" message:@"恭喜你获得100-5优惠劵一张" delegate:self cancelButtonTitle:@"关闭" otherButtonTitles: nil];

[alertView show];

NSLog(@"检测到晃动");

}

}

-(void)prarGotProblem:(NSString *)problemTitle withDetails:(NSString *)problemDetails

{

[self alert:problemTitle withDetails:problemDetails];

}

方法二使用CoreMotion

引入需要的头文件

#import 

下需要检测的 viewDidLoad初始化CMMotionManager 同时启动一个NSTimer检测X、Y、Z轴的变化

- (void)viewDidLoad {

[super viewDidLoad];

// Do any additional setup after loading the view.

NSTimer *AutoTimer = [NSTimer scheduledTimerWithTimeInterval:1.0/60.0 target:self selector:@selector(autoChange) userInfo:nil repeats:YES];

_manager = [[CMMotionManager alloc]init];

_manager.accelerometerUpdateInterval=1.0/60.0;

[_manager startAccelerometerUpdates];

}

-(void)autoChange

{

//根据自己需求调节x y z

if (fabsf(_manager.accelerometerData.acceleration.x) > 1.0 || fabsf(_manager.accelerometerData.acceleration.y) > 1.2 || fabsf(_manager.accelerometerData.acceleration.z) > 0.5)

{

NSLog(@"我晃动了 。。。。。");

}

}

注：方法一中晃动幅度大的情况下才会调用，方法二中可以根据自己的需要调节
