Question

任何人都可以解释一下发生了什么吗？我用这个方法

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

为matchmakerViewController提供横向方向。它可以在iPhone甚至iPad模拟器上完美运行，但不能在iPad设备上运行。当我在iPad上运行应用程序时，matchmakerViewController以纵向方向大量出现。怎么了？我如何解决它？感谢

Answer 1

更改您的shouldAutorotateToInterfaceOrientation

-(BOOL)shouldAutorotateToInterfaceOrientation:( UIInterfaceOrientation)interfaceOrientation
 {     
     return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft || interfaceOrientation == UIInterfaceOrientationLandscapeRight);
 }

同时检查您的应用程序plist文件，键，如支持的界面方向，它的类型将是数组，并且将具有 4值。 从plist中删除纵向模式并保存。它会工作。请检查一下。

Answer 2

（这很可能不是你的问题，但我使用下面的代码并且工作正常）

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

此外，请确保将父视图设置为autorotate true。 shouldAutorotateToInterfaceOrientation doesn't work

Answer 3

这是优雅的解决方案，通过类别，扩展GKMatchMakerViewController，相同的解决方案将适用于任何其他游戏中心视图，如排行榜视图和成就视图：

.h文件

#import <Foundation/Foundation.h>
#import "GameKit/GameKit.h"

@interface GKMatchmakerViewController(LandscapeOnly)



-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation;

@end

.m文件

#import "GKMatchmakerViewController-Landscape.h"

@implementation GKMatchmakerViewController(LandscapeOnly)


-(BOOL) shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {

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


}

@end

让我知道它是否有效!!

Answer 4

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
}


also check parent controller maybe some controller return YES

or try 

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    // Return YES for supported orientations
    if (interfaceOrientation==UIInterfaceOrientationPortrait)
        return (interfaceOrientation == UIInterfaceOrientationLandscapeLeft);
    else 
        return NO;
}

GameCenter横向在iPad上不起作用
