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 <CoreMotion/CoreMotion.h>
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
