我正在学习一些花絮，翻译一些什么与UI加速计
即

[self setAccelometerManager [UIAccelerometer sharedAccelerometer]];

可能成为

[self.motionManager = [[CMMotionManager alloc] init];

设置手动更新间隔，如

[[self accelerometerManager] setUpdateInterval: 0.25];

你可以有

self.motionManager.accelerometerUpdateInterval = 0.25;

并释放委托

self.accelerometerManager.delegate = nil;

现在将

[self.motionManager stopDeviceMotionUpdates];

同样从链接中，我最终做了这样的事情：

motionManager = [[CMMotionManager alloc] init];

motionManager.accelerometerUpdateInterval  = 1.0/10.0; // Update at 10Hz

if (motionManager.accelerometerAvailable) {
    queue = [NSOperationQueue currentQueue];
    [motionManager startAccelerometerUpdatesToQueue:queue withHandler:^(CMAccelerometerData *accelerometerData, NSError *error) {
        switch (currentOrientation) {
            case UIDeviceOrientationLandscapeLeft:
                viewAngle = atan2(accelerometerData.acceleration.x, accelerometerData.acceleration.z);
                break;
            case UIDeviceOrientationLandscapeRight:
                viewAngle = atan2(-accelerometerData.acceleration.x, accelerometerData.acceleration.z);
                break;
            case UIDeviceOrientationPortrait:
                viewAngle = atan2(accelerometerData.acceleration.y, accelerometerData.acceleration.z);
                break;
            case UIDeviceOrientationPortraitUpsideDown:
                viewAngle = atan2(-accelerometerData.acceleration.y, accelerometerData.acceleration.z);
                break;  
            default:
                break;
        }
        [self updateCenterCoordinate];
    }];

}
