IOS開發檢測裝置搖動

裝置搖動檢測的兩種方法簡單的記錄下

方法一

首先在delegate中添加

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

{

    // Override point for customization after application launch

    

    //添加檢測晃動

    application.applicationSupportsShakeToEdit =YES;

}

其次在需要檢測的ViewController中添加

//檢測手機晃動

-(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:@"恭喜你獲得100-5優惠劵一張" delegate:self cancelButtonTitle:@"關閉" otherButtonTitles: nil];

        

        [alertView show];

        

        NSLog(@"檢測到晃動");

    }

}

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

{

    [self alert:problemTitle withDetails:problemDetails];

}

方法二使用CoreMotion

引入需要的標頭檔

#import <CoreMotion/CoreMotion.h>

下需要檢測的 viewDidLoad初始化CMMotionManager 同時啟動一個NSTimer檢測X、Y、Z軸的變化

- (void)viewDidLoad {

    [superviewDidLoad];

    // Do any additional setup after loading the view.

    NSTimer *AutoTimer = [NSTimerscheduledTimerWithTimeInterval:1.0/60.0target:selfselector:@selector(autoChange)userInfo:nilrepeats:YES];

    _manager = [[CMMotionManageralloc]init];

    _manager.accelerometerUpdateInterval=1.0/60.0;

    [_managerstartAccelerometerUpdates];

}

-(void)autoChange

{

    //根據自己需求調節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(@"我晃動了。。。。。");

    }

}

註：方法一中晃動幅度大的情況下才會調用，方法二中可以根據自己的需要調節
