ios 6中的UITabBarController轮换问题

Question

确认!我最终在iOS 5中解决了我的tabbar旋转问题,但是iOS 6和xcode似乎已经破坏了......这就是我所拥有的:

目标应用程序摘要包括:支持的界面方向 - Portraint,Landscape Left,Landscape Right

应用程序中的每个单一视图都有以下方法:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
    return ((interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown) &&
            (interfaceOrientation != UIInterfaceOrientationLandscapeLeft) &&
            (interfaceOrientation != UIInterfaceOrientationLandscapeRight));
} else {
    return YES;
}
}

- (BOOL)shouldAutorotate
{
NSLog(@"am I called1?");
return NO;
}

-(NSUInteger)supportedInterfaceOrientations{
   NSLog(@"am I called?");
   return UIInterfaceOrientationMaskPortrait;
}

在不属于选项卡栏的视图中,旋转被阻止.在标签栏的所有视图中(有5个),应用程序从不调用ShouldAutorotate,因此旋转.它确实看起来supportInterfaceOrientations在视图加载时被调用一次,但是当我在视图之间切换时它不会被调用,因为我得到了NSLog,但似乎忽略了MaskPortrait设置.

我必须在目标中启用横向,因为我有一个需要旋转的视频播放器视图(它确实如此,很好)

这是iOS 6中的tabbar错误吗？我是否需要以不同方式禁用视图的旋转？在ios 5中,shouldautorotatetointerfaceorientation运行良好

我已经有一段时间了

谢谢,扎克

扎克,我遇到了同样的问题.这是因为你将viewController嵌入到TabBar控制器或UINavigationController中,并且这些方法的调用发生在那些方法中,而不是普通的View(在iOS6中更改).

我遇到了这个问题,因为我在我的所有模态视图中呈现了嵌入在UINavigationController中的viewController,这些视图具有导航到不同视图(注册过程,登录等).

我的简单修复是为UINavigationController创建一个包含这两种方法的CATEGORY.我无论如何都应该返回NO,因为我不希望我的模态视图旋转.你的修复可能很简单,试一试.希望能帮助到你.

我创建了一个类别并将其命名为autoRotate并选择了UINavigationController选项.M + H文件如下.

#import "UINavigationController+autoRotate.h"

@implementation UINavigationController (autoRotate)

-(BOOL)shouldAutorotate {
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskPortrait;
}

@end

......和类别.h:

#import <UIKit/UIKit.h>

@interface UINavigationController (autoRotate)

-(BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;

@end

如果您有像我一样的标签栏,您唯一需要做的就是将以下内容添加到您的委托.m文件中,

#import "AppDelegate.h"

//UITabBarController category to set the view rotations for ios 6
@implementation UITabBarController (Background)

-(BOOL)shouldAutorotate
{
    //I don't want to support auto rotate, but you can return any value you want here
    return NO;
}

- (NSUInteger)supportedInterfaceOrientations {
    //I want to only support portrait mode
    return UIInterfaceOrientationMaskPortrait;
}

@end


/////here starts the implementation of the app delegate which is gonna be whatever you currently have on your .m delegate

@implementation AppDelegate

// delegate methods and other stuff

@end

我还遇到了一个问题,我需要一些视图来旋转,而其他视图则不需要多个导航控制器.我通过告诉NavigationController查看视图控制器来做到这一点.这就是我做的.

我创建了一个名为RootNavigationController的UINavigationController类,并将该类指定为故事板中导航控制器的自定义类.在RootNavigationController.m中,我添加了以下方法;

- (BOOL)shouldAutorotate {

    return [self.visibleViewController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations {
    return [self.visibleViewController supportedInterfaceOrientations];    
}

在每个视图控制器.m文件中,我还添加了以下方法.

- (BOOL)shouldAutorotate {
    //return yes or no
}

- (NSUInteger)supportedInterfaceOrientations{
    //return supported orientation masks
}

这样做允许我在视图控制器中为每个视图设置方向.

无论如何,为我工作......

我的情况是:

• UITabBarController有2个项目:2导航控制器
• UINavigationController1 withRootView:ViewController1
• UINavigationController2 withRootView:ViewController2.
• 现在我想要ViewController1设置shouldAutorotate:NO/maskPortrait和ViewController2设置shouldAutorotate/MaskAll.

所以我的工具:创建UITabBarController类和UINavigationCntroller类

的UITabBarController + autoRotate.h

@interface UITabBarController (autoRotate)

-(BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;

@end

的UITabBarController + autoRotate.m

#import "UITabBarController+autoRotate.h"

@implementation UITabBarController (autoRotate)

- (BOOL)shouldAutorotate {
    return [self.selectedViewController shouldAutorotate];
}
- (NSUInteger)supportedInterfaceOrientations {
    return [self.selectedViewController supportedInterfaceOrientations];
}

@end

UINavigationController的+ autoRotate.h

@interface UINavigationController (autoRotate)

-(BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;

@end

UINavigationController的+ autoRotate.m

@implementation UINavigationController (autoRotate)

- (BOOL)shouldAutorotate {
    return [self.visibleViewController shouldAutorotate];
}

- (NSUInteger)supportedInterfaceOrientations {
    return [self.visibleViewController supportedInterfaceOrientations];
}

@end

UIViewController1.m

- (BOOL)shouldAutorotate {
    return NO;
}
- (NSUInteger)supportedInterfaceOrientations {
   return UIInterfaceOrientationMaskPortrait;;
}

UIViewController2.m

- (BOOL)shouldAutorotate {
   return YES;
}
- (NSUInteger)supportedInterfaceOrientations {
   return UIInterfaceOrientationMaskAll;
}

它就像一个魅力!
