在我的自定义标签栏应用程序中,方向似乎永远不会改变,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>
#import "MBProgressHUD.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"
#import "exampleViewContoller.h"
#import "example1ViewController.h"
#import "example2ViewController.h"
#import "example3ViewController.h"
#import "example4ViewController.h"
#import "SBJson.h"
#define TMP NSTemporaryDirectory()

@implementation <appname>AppDelegate

@synthesize window = _window;
@synthesize rootController;
@synthesize viewController;
@synthesize viewController1;
@synthesize viewController2;
@synthesize viewController3;
@synthesize viewController4;
@synthesize tweets;

CGFloat width = self.rootController.view.bounds.size.width;
CGFloat height = self.rootController.view.bounds.size.height;
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, width, height)];
UIImage *imageView = [UIImage imageNamed:@"TabBarBackground.png"];
UIColor *kMainColor = [[UIColor alloc] initWithPatternImage:imageView];

[v setBackgroundColor:kMainColor];
[kMainColor release];

[self.rootController.tabBar insertSubview:v atIndex:0];
[imageView release];
[v release];

responseData = [[NSMutableData data] retain];
tweets = [NSMutableArray array];
NSURLRequest *request = [NSURLRequest requestWithURL:
[NSURL URLWithString:@"http://api.twitter.com/1/statuses/user_timeline.json?screen_name=ENTER_USER_HERE&count=20"]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];

NSAssert(nil != self.rootController, @"tab bar controller not hooked up!");

BOOL iPad = NO;
#ifdef UI_USER_INTERFACE_IDIOM
iPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
#endif

if (iPad) {
self.viewController = [[[exampleViewContoller alloc] initWithNibName:@"exampleViewController_iPad" bundle:nil] autorelease];
self.viewController1 = [[example1ViewController alloc] initWithNibName:@"example1ViewController_iPad" bundle:nil] autorelease];
self.viewController2 = [[[example2ViewController alloc] initWithNibName:@"example2ViewController_iPad" bundle:nil] autorelease];
self.viewController3 = [[[example3ViewController alloc] initWithNibName:@"example3ViewController_iPad" bundle:nil] autorelease];
self.viewController4 = [[[example4ViewController alloc] initWithNibName:@"example4ViewController_iPad" bundle:nil] autorelease];
} else {

}
self.rootController.viewControllers = [NSArray arrayWithObjects:self.viewController, self.viewController4, self.viewController1, self.viewController3, self.viewController2, nil];

[viewController release];
[viewController1 release];
[viewController2 release];
[viewController3 release];
[viewController4 release];

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_4_0
self.window.rootViewController = self.rootController;
#else
[self.window addSubview:rootController.view];
#endif
[self.window makeKeyAndVisible];
HUD = [[MBProgressHUD alloc] initWithView:viewController.view];
[viewController.view addSubview:HUD];
[HUD show:NO];

HUD.delegate = self;

HUD.labelText = @"Loading";


return YES;
}

//[---CODE CLIP---]

- (void)application:(UIApplication *)application didChangeStatusBarOrientation:(UIInterfaceOrientation)oldStatusBarOrientation {
CGFloat width = self.rootController.view.bounds.size.width*2;
CGFloat height = self.rootController.view.bounds.size.height;
UIView *v = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, width, height)];
UIImage *imageView = [UIImage imageNamed:@"TabBarBackground.png"];
UIColor *kMainColor = [[UIColor alloc] initWithPatternImage:imageView];

[v setBackgroundColor:kMainColor];
[kMainColor release];
[self.rootController.tabBar insertSubview:v atIndex:0];
[imageView release];
[v release];

}

- (void)hudWasHidden {
[HUD removeFromSuperview];
}

//[---CODE CLIP---]

- (void)dealloc
{
[_window release];
[rootController release];
[HUD release];
[super dealloc];
}

@end

问题是当我在 iOS 模拟器中旋转设备时,应用程序不会旋转。任何想法将不胜感激!

更新

我还注意到启动图像也没有旋转(对于 iPad,即 iPhone 不做横向启动图像)。

JMANS 注释

我覆盖了 UITabBarController:
@implementation UITabBarController (MyApp)

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation {
if(self.selectedIndex==4)
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
else
return (toInterfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
}
@end

最佳答案

我将首先将其包含在您的所有 View Controller 中:

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

此外,请确保您在 Info.plist 中支持多个方向。
