您现在的增强现实应用程序有多远?我认为首先看一下 Apple 的 PARk 是很苛刻的。你需要有一些高级的数学理解。但如果你这样做,为什么不呢!
你可以看看这个存储库,这是一个在纵向和横向模式下工作的增强现实项目。以下是旋转的处理方式:
- (void)deviceOrientationDidChange:(NSNotification *)notification {
prevHeading = HEADING_NOT_SET;
[self currentDeviceOrientation];
UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
// Later we may handle the Orientation of Faceup to show a Map. For now let's ignore it.
if (orientation != UIDeviceOrientationUnknown && orientation != UIDeviceOrientationFaceUp && orientation != UIDeviceOrientationFaceDown) {
CGAffineTransform transform = CGAffineTransformMakeRotation(degreesToRadian(0));
CGRect bounds = [[UIScreen mainScreen] bounds];
switch (orientation) {
case UIDeviceOrientationLandscapeLeft:
transform = CGAffineTransformMakeRotation(degreesToRadian(90));
bounds.size.width = [[UIScreen mainScreen] bounds].size.height;
bounds.size.height = [[UIScreen mainScreen] bounds].size.width;
break;
case UIDeviceOrientationLandscapeRight:
transform = CGAffineTransformMakeRotation(degreesToRadian(-90));
bounds.size.width = [[UIScreen mainScreen] bounds].size.height;
bounds.size.height = [[UIScreen mainScreen] bounds].size.width;
break;
case UIDeviceOrientationPortraitUpsideDown:
transform = CGAffineTransformMakeRotation(degreesToRadian(180));
break;
default:
break;
}
[displayView setTransform:CGAffineTransformIdentity];
[displayView setTransform: transform];
[displayView setBounds:bounds];
degreeRange = [self displayView].bounds.size.width / ADJUST_BY;
}
}
您必须旋转所有注释,然后在设备旋转后旋转覆盖视图!
