我在尝试阻止某些视图中的方向时遇到问题,但代码不是工作属性.
我在每个视图中使用这些行：
- (BOOL)shouldAutorotate
{
return YES;
}
- (NSUInteger)supportedInterfaceOrientations
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
return UIInterfaceOrientationMaskPortrait;
} else {
return UIInterfaceOrientationMaskAll;
}
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
它几乎可以在使用UINavigationController的视图中工作,但是在使用UITabBarController的视图中我遇到了很大的问题,因为它接缝代码没有被调用.
解决方法
好吧我解决了,你必须继承UINavigationController和UITabBarController,所以这里是代码：
//cCustomNavigationController.h file
#import <UIKit/UIKit.h>
@interface cCustomNavigationController : UINavigationController <UINavigationControllerDelegate>
@end
//cCustomNavigationController.m file
#import "cCustomNavigationController.h"
@interface cCustomNavigationController ()
@end
@implementation cCustomNavigationController
- (BOOL)shouldAutorotate {
return [self.visibleViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations {
return [self.visibleViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return [self.visibleViewController preferredInterfaceOrientationForPresentation];
}
@end
//cCustomTabController.h file
#import <UIKit/UIKit.h>
@interface cCustomTabController : UITabBarController <UITabBarControllerDelegate>
@end
//cCustomTabController.m file
#import "cCustomTabController.h"
@interface cCustomTabController ()
@end
@implementation cCustomTabController
- (BOOL)shouldAutorotate {
return [self.selectedViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations {
return [self.selectedViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {
return [self.selectedViewController preferredInterfaceOrientationForPresentation];
}
@end
现在你只需要在你需要它的地方创建你的TabBarController或者你的NavigationController,即
//For the UINavigationController UINavigationController *navigationController = [[cCustomNavigationController alloc] init]; //For the UITabBarController UITabBarController *tabController = [[cCustomTabController alloc] init];
我希望这能帮到你们.
