处理iOS6中的旋转 [英] Handling Rotation in iOS6

问题描述

我只想在我的UINavigationController堆栈中的一个View上支持不同的Orientations。我怎样才能做到这一点？

它也必须在iOS5中运行。

解决方案

我'我对iOS6如何处理Orientation有很多麻烦，希望这是你正在寻找的。

创建一个UINavigationController类并称之为UINavigationController + autoRotate 。

把它放在你的UINavigationController + autoRotate.h中：

  #import< UIKit / UIKit.h> 
 
 @interface UINavigationController（autoRotate）
 
  - （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）toInterfaceOrientation; 
  - （BOOL）shouldAutorotate; 
  - （NSUInteger）supportedInterfaceOrientations; 
 
 @end 
  

将此放入UINavigationController + autoRotate.m：

  #importUINavigationController + autoRotate.h
 
 @implementation UINavigationController（autoRotate）
 
  - （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation 
 {
 return [self.topViewController shouldAutorotateToInterfaceOrientation：interfaceOrientation]; 
} 
 
  - （BOOL）shouldAutorotate 
 {
 return [self.visibleViewController shouldAutorotate]; 
} 
 
 
  - （NSUInteger）supportedInterfaceOrientations 
 {
 if（！[[self.viewControllers lastObject] isKindOfClass：NSClassFromString（@ViewController） ]）
 {
返回UIInterfaceOrientationMaskAllButUpsideDown; 
} 
 else 
 {
 return [self.topViewController supportedInterfaceOrientations]; 
} 
} 
 
 @end 
  

您不想旋转的视图，添加：

   - （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation 
 { 
 return（interfaceOrientation == UIInterfaceOrientationPortrait）; 
} 
 
  - （NSUInteger）supportedInterfaceOrientations 
 {
返回UIInterfaceOrientationMaskPortrait; 
} 
 
  - （BOOL）shouldAutorotate 
 {
 return NO; 
} 
  

对于你想要旋转的视图：

   - （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation 
 {
 return（interfaceOrientation！= UIDeviceOrientationPortraitUpsideDown）; 
} 
 
  - （NSUInteger）supportedInterfaceOrientations 
 {
返回UIInterfaceOrientationMaskAllButUpsideDown; 
} 
 
  - （BOOL）shouldAutorotate 
 {
返回YES; 
} 
  

在你的App代表中，添加：

   - （NSUInteger）应用程序：（UIApplication *）application supportedInterfaceOrientationsForWindow：（UIWindow *）window 
 {
 return UIInterfaceOrientationMaskAllButUpsideDown; 
} 
  

I only want to support different Orientations on one View in my UINavigationController Stack. How can I do this?

It also has to work in iOS5.

解决方案

I've had a lot of trouble with how iOS6 handles Orientation, hopefully this is what you're looking for.

Create a category of UINavigationController and call it "UINavigationController+autoRotate".

Put this in your UINavigationController+autoRotate.h:

#import <UIKit/UIKit.h>

@interface UINavigationController (autoRotate)

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;
-(BOOL)shouldAutorotate;
- (NSUInteger)supportedInterfaceOrientations;

@end

Put this in UINavigationController+autoRotate.m:

#import "UINavigationController+autoRotate.h"

@implementation UINavigationController (autoRotate)

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return [self.topViewController shouldAutorotateToInterfaceOrientation:interfaceOrientation];
}

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


- (NSUInteger)supportedInterfaceOrientations
{
    if (![[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"ViewController")])
    {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
    else
    {
        return [self.topViewController supportedInterfaceOrientations];
    }
}

@end

For Views that you DO NOT want to rotate, add:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (BOOL)shouldAutorotate
{
    return NO;
}

And for Views you DO want to rotate:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation != UIDeviceOrientationPortraitUpsideDown);
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

- (BOOL)shouldAutorotate
{
    return YES;
}

In your App's delegate, add:

- (NSUInteger)application:(UIApplication*)application supportedInterfaceOrientationsForWindow:(UIWindow*)window
{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}
