考虑到:
视图A:仅竖屏 - 视图B:仅横屏
我不能在导航控制器中实现它。相反,我打开了一个模态视图从视图A到视图B,并将一个新的导航控制器强行置于该视图。
这对我来说在iOS5+上可行。
你需要为导航控制器创建一个类别,像这样:
UINavigationController+Rotation_IOS6.h
#import <UIKit/UIKit.h>
@interface UINavigationController (Rotation_IOS6)
- (BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation;
@end
UINavigationController+Rotation_IOS6.h
#import "UINavigationController+Rotation_IOS6.h"
@implementation UINavigationController (Rotation_IOS6)
- (BOOL)shouldAutorotate
{
return [self.topViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations
{
return [self.topViewController supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [self.topViewController preferredInterfaceOrientationForPresentation];
}
@end
在
AppDelegate.m中添加以下内容:
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{
return UIInterfaceOrientationMaskAll;
}
接下来在A视图中:
- (BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationPortrait;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationPortrait || interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown);
}
同样在视图 A 中打开视图 B,请执行以下操作:
ViewB *vc = [[ViewB alloc] initWithNibName:@"ViewB" bundle:nil];
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:vc];
[self presentViewController:navigationController animated:YES completion:nil];
最后,在
视图B 中。
- (BOOL)shouldAutorotate {
return YES;
}
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscapeRight | UIInterfaceOrientationMaskLandscapeLeft;
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return UIInterfaceOrientationLandscapeRight;
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation == UIInterfaceOrientationLandscapeRight || interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}
