ios – 用陀螺仪滚动图像有问题

概述iPad Air有一个奇怪的问题！ ,我的代码在iPad 3,iPad 4,iPhone 5S,iPod 5th Gen上运行良好,但在iPad上,我的图像自动滚动而无需用户旋转设备,这是我的代码： @property (strong, nonatomic) CMMotionManager *motionManager; self.mainScrollView.frame = CGRe iPad Air有一个奇怪的问题！,我的代码在iPad 3,iPad 4,iPhone 5S,iPod 5th Gen上运行良好,但在iPad上,我的图像自动滚动而无需用户旋转设备,这是我的代码：

@property (strong,nonatomic) cmmotionmanager *motionManager;    self.mainScrollVIEw.frame = CGRectMake(0,self.vIEw.frame.size.wIDth,self.vIEw.frame.size.height);    self.mainScrollVIEw.bounces = NO;    self.mainScrollVIEw.userInteractionEnabled = NO;    //set up the image vIEw    UIImage *image= [UIImage imagenamed:@"YOUR_IMAGE_name"];    UIImageVIEw *movingImageVIEw = [[UIImageVIEw alloc]initWithImage:image];    [self.mainScrollVIEw addSubvIEw:movingImageVIEw];    self.mainScrollVIEw.contentSize = CGSizeMake(movingImageVIEw.frame.size.wIDth,self.mainScrollVIEw.frame.size.height);    self.mainScrollVIEw.contentOffset = CGPointMake((self.mainScrollVIEw.contentSize.wIDth - self.vIEw.frame.size.wIDth) / 2,0);    //inital the motionManager and detec the Gyroscrope for every 1/60 second    //the interval may not need to be that fast    self.motionManager = [[cmmotionmanager alloc] init];    self.motionManager.gyroUpdateInterval = 1/60;    //this is how fast the image should move when rotate the device,the larger the number,the less the roation required.

这是一种动画!!!此代码在其他设备上正常工作！有什么帮助吗？谢谢

解决方法 你能尝试以下方法吗？
这会将错误处理添加到您的代码中,因为可能会从陀螺仪返回错误,并且这可能返回值> 0.09;在测试时更频繁地使用NSLOG来挑选代码并查看返回的值.
