iOS 6.0 中的界面方向 [英] Interface orientation in iOS 6.0

问题描述

如何在iOS 6.0中使用以下方法支持界面方向:

How to use the following methods to support interface orientation in iOS 6.0:

shouldAutorotate

supportedInterfaceOrientations

preferredInterfaceOrientationForPresentation

因为 iOS 6.0 中不推荐使用shouldAutorotateToInterfaceOrientation".

As "shouldAutorotateToInterfaceOrientation" is deprecated in iOS 6.0.

请提供代码片段以支持您的回答.

Please provide code snippets to support your answers.

谢谢.

推荐答案

iOS 5 中已弃用的方法:

Deprecated method in iOS 5:

// Override to allow orientations other than the default portrait orientation.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight);
}

iOS 6 中的替换和上面这个已弃用的 iOS 5 方法的等效方法:

Replacement in iOS 6 and equivalent of this deprecated iOS 5 method above:

- (BOOL) shouldAutorotate
{
    return YES;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskLandscapeRight;
}

希望这会有所帮助.

#import "FirstViewController.h"

@interface FirstViewController ()

@end

@implementation FirstViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self)
    {
        // Custom initialization
    }

    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
}

-(BOOL)shouldAutorotate
{
    return NO;
}

-(NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskAll;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
    return UIInterfaceOrientationMaskPortrait;
}

[#edit 2:来自支持 iOS 5 和 iOS 6 的仅横向应用程序的示例代码]

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    return (interfaceOrientation == UIInterfaceOrientationLandscapeRight) || (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}

- (BOOL)shouldAutorotate {

    return YES;
}

- (NSUInteger)supportedInterfaceOrientations {

    return UIInterfaceOrientationMaskLandscape;
}

- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation {

    return UIInterfaceOrientationLandscapeLeft;
}
