我希望保持自己的视野。为此,我使用此代码,但BAD_ACCESS即将到来。 在这里,我正在为相机overlayView编写此代码。
-(void)viewDidLoad
{
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
//Set Notifications so that when user rotates phone, the orientation is reset to landscape.
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
//Refer to the method didRotate:
[[NSNotificationCenter defaultCenter] addObserver:self
selector:@selector(didRotate:)
name:@"UIDeviceOrientationDidChangeNotification" object:nil];
[super viewDidLoad];
}
- (void) didRotate:(NSNotification *)notification
{
//Maintain the camera in Landscape orientation
[[UIDevice currentDevice] setOrientation:UIInterfaceOrientationLandscapeLeft];
}
为什么要给予BAD ACCESS?
答案 0 :(得分:4)
要保持您的观看格局,只需在NO
方法中返回shouldAutorotateToInterfaceOrientation:
纵向方向,例如:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
