将纵向模式设置为横向

Question

我尝试使用类别.... 添加新文件并选择 Category 并创建子类 UINavigationController 类。

这是 .h 的类别代码

    #import <UIKit/UIKit.h>
    #import "AppDelegate.h"

    @interface UINavigationController (orientation)

    @end

code for .m file

#import "UINavigationController+orientation.h"

@implementation UINavigationController (orientation)

- (BOOL)shouldAutorotate
{
    return YES;
}

- (NSUInteger)supportedInterfaceOrientations
{

    AppDelegate * delegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];

    if (delegate.islandscape)
    {
        // for iPhone, you could also return UIInterfaceOrientationMaskAllButUpsideDown
        return UIInterfaceOrientationMaskLandscape;

    }
    return UIInterfaceOrientationMaskPortrait;

}
@end

在 App 委托中声明 isLandscape 以检查天气 First view controller 或 secondView Controller isLandscape is Bool.

现在 FirstViewController.m 文件我希望在 Portarit 模式下使用此代码

- (IBAction)PlayClicked:(id)sender
{
    AppDelegate * delegate=(AppDelegate *)[[UIApplication sharedApplication]delegate];


    self.navigationController.navigationBarHidden=YES;
    delegate.islandscape=YES;

    ViewController * v=[[ViewController alloc]initWithNibName:@"ViewController" bundle:nil];

    [self presentViewController:v animated:NO completion:nil];


    //[self dismissViewControllerAnimated:YES completion:nil];
   [self.navigationController pushViewController:v animated:YES];

}


- (NSInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

我希望 SecondViewController 在横向模式下使用这个。

delegate.islandscape=NO;   // called transfer to Category 

- (NSInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscape;
}

我推荐这个 1st ViewController in Protrait and SecondViewController in Landscape Mode 和这个 Landscape Apps Xcode 5 / iOS 7 和其他但不适合我
