在xcode4.3.1中如何创建 window-based Application 工程。
在xcode 4.2中如何创建 window-based Application.
老外写的方法，写得非常清楚，就不用翻译了。出处也找不到，抱歉！
In the tutorial that I am learning at the moment, it requires “Window-based application”.
Xcode 4.2 beta 4 does not have “window-based application”; so, I created a project with “Empty application”.
Unfortunately, “Empty application” has no longer “MainWindow.xib”, which tutorial teacher said to modify something in it.
So, I googled to make “MainWindow.xib” visible and found this article.
“MainWindow.xib” posted by Jeroen Trappers
What he said is that “MainWindow.xib” is not included by default in templates. He suggested to create “MainWindow.xib” manually as below:
(FYI, this instruction is only for me. It is better to go to original article and follow.)
1. Create new project in Xcode 4.2 beta and choose “Empty Application” template
2. Add “New File” to the project by choosing “iOS -> User Interface -> Empty”
3. Choose “iPhone” and name “MainWindow” (.xib will be added automatically)
4. Open “MainWindow.xib” in project navigator
5. Click “File’s Owner” in “Placeholders”
Change Class as “UIApplication” in “Identity Inspector”
6. Drag “Object” in the library into “Objects” panel on the left
7. Change the class of the Object as your delegate class, such as “DemoAppDelegate”
(The name of object will be automatically change like “Demo App Delegate”)
8. Drag “Window” in the library into “Objects” panel on the left
9. Open “DemoAppDelegate.h” in project navigator
10. Find below code
@interface DemoAppDelegate :
UIResponder
@property (strong, nonatomic)UIWindow *window;
@end
11. Change as below:
@interface DemoAppDelegate :
UIResponder
@property (strong, nonatomic) IBOutlet UIWindow *window;
@end
11. Open “MainWindow.xib” in project navigator
12. Click “File’s Owner” in “Placeholders”
13. Control-Drag “delegate” of “Outlets” in “Connections Inspector” to “Demo App Delegate” in “Objects”
14. Click “Demo App Delgate” in “Objects”
15. Control-Drage “window” of “Outlets” in “Connections Inspector” to “Window” in “Objects”
16. Open “Summary” of your project
17. Find “iPhone / iPod Deployment Info”
18. Change “Main Interface” as “MainWindow”
19. Open “DemoAppDelegate.m” in project navigator
20. Find below code
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
21. Change as below
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
//self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
//self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}
