问题描述
我正在尝试使用Xcode 4构建一个通用应用程序。但是，它似乎与过去的版本有点不同。
I am trying to build an universal application with Xcode 4. However, it seems a little different from past versions.
我的项目使用基于视图的应用程序模板。我的问题是我添加了一个 UIViewController 子类，它有一个用于iPad的nib文件。如何为iPhone创建另一个具有相同类的nib文件？另外，如何确保为正确的平台加载正确的nib文件？
My project utilizes the View Based Application template. My issue is that I added a UIViewController subclass which has one nib file for iPad. How do I create another nib file with the same class targeted instead for iPhone? Also, how do I ensure that the proper nib file is loaded for the proper platform?
编辑：
这是我的代码：
EDITED :here is my code :
- (IBAction)BookView {
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
BookViewController *viewController = [[BookViewController alloc] initWithNibName:@"BookViewController" bundle:nil];
[self presentModalViewController:viewController animated:YES];
} else {
BookViewController *viewController = [[BookViewController alloc] initWithNibName:@"BookViewController_iPad" bundle:nil];
[self presentModalViewController:viewController animated:YES];
}
}
推荐答案
步骤1：为iPhone创建：
Step 1: Create for iPhone:
- 新文件/ ios / cocoa touch / UIViewController子类
- 取消选中针对iPad的目标
- 使用XIB查看
此步骤将创建具有相同名称的.m .h和.xib文件，例如：CustomView
This step will create .m .h and .xib files with same name, for example: CustomView
步骤2：为iPad创建新的XIB：
Step 2: Create new XIB for iPad:
- 新文件/ ios /用户界面/查看
设备系列iPad - 为方便起见选择在此xib中使用后缀_iPad（例如CustomView_iPad）
- 的相同名称转到文件所有者，在检查器选项卡中选择身份检查器，自定义类并选择在步骤中创建的同一名称类1。
- 连接IBOutlets。
- New file / ios / user interface / viewdevice family iPad
- for convenience choose the same name with suffix _iPad (for example CustomView_iPad)
- in this xib go to File's Owner, in the inspector tabs choose identity inspector, custom class and choose the same name of class created in step 1.
- Connect IBOutlets.
在您的代码中使用以下内容：
In your code use something like this:
if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
CustomView *viewController = [[CustomView alloc] initWithNibName:@"CustomView" bundle:nil];
} else {
CustomView *viewController = [[CustomView alloc] initWithNibName:@"CustomView_iPad" bundle:nil];
}
