[英]BAD_ACCESS while landscape orientation
我想保留我的风景。 为此,我正在使用此代码,但 BAD_ACCESS 即将到来。 在这里,我正在为相机 overlayView 编写这段代码。
-(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];
}
为什么它给 BAD ACCESS?
为了让你的视图保持横向,只需在你的shouldAutorotateToInterfaceOrientation:
纵向方法中返回NO
,比如 tihs:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return UIInterfaceOrientationIsLandscape(interfaceOrientation);
}
