在哪里可以找到有关在 iPhone 上使用 UISplitViewController 的通用应用程序的信息？
我已经关注了我发现的所有关于创建通用应用程序的帖子，该应用程序使用 UISplitViewController 并在 iPhone（当然没有它）和 iPad 上运行良好。
我的目标设备系列是 => iPhone/iPad iPhone操作系统部署=> iPhone操作系统3.0 基础 SDK => iPhone 设备 3.2
我的 UIKit.framework 在我的目标常规中是“弱引用”
在我使用 UISplitViewController *splitViewController 的地方；我收到错误了。
据我所知，iPhone SDK 3.x 没有 UISplitViewController，但 SDK 的基础是 3.2。
我应该使用这样的条件吗？
Class splitVCClass = NSClassFromString(@"UISplitViewController");
if (splitVCClass)
{
UISplitViewController* mySplitViewController = [[splitVCClass alloc] init];
// Configure the split view controller.
}
但我在这里会遇到与再次使用 UISplitViewController 相同的错误...
谢谢！
问候，

通用代码：
#import <UIKit/UIKit.h>
@class iPad_RootViewController;
@class iPad_DetailViewController;
@interface AppDelegate_Pad : NSObject <UIApplicationDelegate> {
UIWindow *window;
UISplitViewController *splitViewController;
iPad_RootViewController *rootViewController;
iPad_DetailViewController *detailViewController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;
@property (nonatomic, retain) IBOutlet iPad_RootViewController *rootViewController;
@property (nonatomic, retain) IBOutlet iPad_DetailViewController *detailViewController;
@end
错误是：
iPad/AppDelegate_Pad.h:18: error: expected specifier-qualifier-list before 'UISplitViewController'
UISplitViewController 是黑色的，就像它没有被标记
一样 我也遵循了这个： Apple iPad 编程指南
I've followed all posts that I've found about creating a Universal App that uses a UISplitViewController and runs fine on iPhone (without it, of course) and in iPad.
My Targeted Device Familiy is => iPhone/iPad
iPhone OS Deployment => iPhone OS 3.0
Base SDK => iPhone Device 3.2
My UIKit.framework is 'weak ref' in my Target General
In the place where I use the UISplitViewController *splitViewController; I'm getting the error.
I understand that the iPhone SDK 3.x doesn't have the UISplitViewController but the base of the SDK is 3.2.
Should I use conditionals like this ?
Class splitVCClass = NSClassFromString(@"UISplitViewController");
if (splitVCClass)
{
UISplitViewController* mySplitViewController = [[splitVCClass alloc] init];
// Configure the split view controller.
}
But I'm going to have the same error here as using again the UISplitViewController ...
Thanks !
regards,

general code:
#import <UIKit/UIKit.h>
@class iPad_RootViewController;
@class iPad_DetailViewController;
@interface AppDelegate_Pad : NSObject <UIApplicationDelegate> {
UIWindow *window;
UISplitViewController *splitViewController;
iPad_RootViewController *rootViewController;
iPad_DetailViewController *detailViewController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UISplitViewController *splitViewController;
@property (nonatomic, retain) IBOutlet iPad_RootViewController *rootViewController;
@property (nonatomic, retain) IBOutlet iPad_DetailViewController *detailViewController;
@end
And the error is:
iPad/AppDelegate_Pad.h:18: error: expected specifier-qualifier-list before 'UISplitViewController'
And the UISplitViewController is black, like it hasn't been tokenized
Also I've followed this: Apple iPad Programming Guide

好吧，我发现问题只出现在模拟器中运行时，因为我被迫编译到 3.x 并且 UISplitViewController 不在这个 SDK 中，所以我必须在它周围添加一堆 #ifdef .. 。
OK, I see that the problem is only when running in the Simulator, as I'm forced to compile to 3.x and the UISplitViewController isn't in this SDK, so I have to add a bunch of #ifdef around it ...
Apple 文档称“iPhone OS 部署 => iPhone OS 3.1.3”适用于通用应用程序。
并且，尝试这样，
Apple Documentation says "iPhone OS Deployment => iPhone OS 3.1.3" for universal apps.
and, try like this,
