iOS获取手机倾斜角度

最近一个埋点上的小需求,百度里找到的都不是很好用.

1.引入头文件<CoreMotion/CoreMotion.h> 以及在linked里加入这个包.

- (void)viewDidLoad {

[superviewDidLoad];

CMMotionManager*motionManager = [[CMMotionManageralloc]init];

NSOperationQueue*queue = [[NSOperationQueuealloc]init];

//加速计

if(motionManager.accelerometerAvailable) {

motionManager.accelerometerUpdateInterval=0.5;

[motionManagerstartAccelerometerUpdatesToQueue:queuewithHandler:^(CMAccelerometerData*accelerometerData,NSError*error){

if(error) {

[motionManagerstopAccelerometerUpdates];

NSLog(@"error");

}else{

doublezTheta =atan2(accelerometerData.acceleration.z,sqrtf(accelerometerData.acceleration.x*accelerometerData.acceleration.x+accelerometerData.acceleration.y*accelerometerData.acceleration.y))/M_PI*(-90.0)*2-90;

doublexyTheta =atan2(accelerometerData.acceleration.x,accelerometerData.acceleration.y)/M_PI*180.0;

NSLog(@"手机与水平面的夹角是%.2f,手机绕自身旋转的角度是%.2f",-zTheta,xyTheta);

}

}];

}else{

NSLog(@"This device has no accelerometer");

}

}
