iOS（iPhone / iPad）SDK - 应用程序不更改方向 [英] iOS (iPhone/iPad) SDK - Application not changing orientation
本文介绍了iOS（iPhone / iPad）SDK - 应用程序不更改方向的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的自定义标签栏应用程序中，方向似乎不会改变，即使我强制旋转状态栏。这是我的AppDelegate中的代码：
AppDelegate.h：
#import< UIKit / UIKit.h>
#importMBProgressHUD.h
@class exampleViewContoller;
@class example1ViewController;
@class example2ViewController;
@class example3ViewController;
@class example4ViewController;
@interface< appname> AppDelegate：NSObject< UIApplicationDelegate，MBProgressHUDDelegate> {
UIWindow * window;
UITabBarController * rootController;
exampleViewContoller * viewController;
example1ViewController * viewController1;
example2ViewController * viewController2;
example3ViewController * viewController3;
example4ViewController * viewController4;
NSMutableData * responseData;
NSMutableArray * tweets;
MBProgressHUD * HUD;
}
@property（nonatomic，retain）IBOutlet UIWindow * window;
@property（nonatomic，retain）IBOutlet UITabBarController * rootController;
@property（nonatomic，retain）IBOutlet exampleViewContoller * viewController;
@property（nonatomic，retain）IBOutlet example1ViewController * viewController1;
@property（nonatomic，retain）IBOutlet example2ViewController * viewController2;
@property（nonatomic，retain）IBOutlet example3ViewController * viewController3;
@property（nonatomic，retain）IBOutlet example4ViewController * viewController4;
@property（nonatomic，retain）NSMutableArray * tweets;
@end
AppDelegate.m：
#import< appname> AppDelegate.h
#importexampleViewContoller.h
#importexample1ViewController.h
#importexample2ViewController.h
#importexample3ViewController.h

问题是，当我在iOS模拟器中旋转设备，应用程序不会旋转。非常感谢任何想法！
UPDATE
我也注意到启动图像也不旋转（对于iPad，iPhone不执行横向启动图像）。
注意JMANS p>
我覆盖UITabBarController：
@implementation UITabBarController b
- （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）toInterfaceOrientation {
if（self.selectedIndex == 4）
return（toInterfaceOrientation == UIInterfaceOrientationPortrait）;
else
return（toInterfaceOrientation！= UIInterfaceOrientationPortraitUpsideDown）;
}
@end
解决方案
我会从所有的视图控制器开始：
- （BOOL）shouldAutorotateToInterfaceOrientation：（UIInterfaceOrientation）interfaceOrientation {
return YES;
}
此外，请确保您在Info.plist中支持多个方向。
In my custom Tab Bar Application, the orientation never seems to change, even if I force rotate the status bar. Here is my code in my AppDelegate:
AppDelegate.h:
#import <UIKit/UIKit.h>
#import "MBProgressHUD.h"
@class exampleViewContoller;
@class example1ViewController;
@class example2ViewController;
@class example3ViewController;

@interface <appname>AppDelegate : NSObject <UIApplicationDelegate, MBProgressHUDDelegate> {
UIWindow *window;
UITabBarController *rootController;
exampleViewContoller *viewController;
example1ViewController *viewController1;
example2ViewController *viewController2;
example3ViewController *viewController3;
example4ViewController *viewController4;
NSMutableData *responseData;
NSMutableArray *tweets;
MBProgressHUD *HUD;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *rootController;
@property (nonatomic, retain) IBOutlet exampleViewContoller *viewController;
@property (nonatomic, retain) IBOutlet example1ViewController *viewController1;
@property (nonatomic, retain) IBOutlet example2ViewController *viewController2;
@property (nonatomic, retain) IBOutlet example3ViewController *viewController3;
@property (nonatomic, retain) IBOutlet example4ViewController *viewController4;
@property (nonatomic, retain) NSMutableArray *tweets;
@end

UIColor *kMainColor = [[UIColor alloc] initWithPatternImage:imageView];
[v setBackgroundColor:kMainColor];

[self.rootController.tabBar insertSubview:v atIndex:0];
[imageView release];
[v release];
responseData = [[NSMutableData data] retain];

}
@end
The problem is that when I rotate the device in iOS Simulator, the application won't rotate. Any ideas would be much appreciated!
UPDATE
I have also noticed that the launch image is also not rotating (for iPad that is - iPhone doesn't do landscape launch images).
NOTE FOR JMANS
I overrode UITabBarController:
@implementation UITabBarController (MyApp)
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
if(self.selectedIndex==4)
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
else
return (toInterfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
@end
解决方案
I would start by including this in all of your view controllers:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
return YES;
}
Also, make sure that you are supporting multiple orientations in your Info.plist.
