Where is the applicationDidFinishLaunching function?
提问by Phillip Senn
My documentation says:
我的文档说：
Add the codes below into the applicationDidFinishLaunching function... -(void)applicationDidFinishLaunching:(UIApplication *)application{
将以下代码添加到 applicationDidFinishLaunching 函数中... -(void)applicationDidFinishLaunching:(UIApplication *)application{
But I only see
但我只看到
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
Q: Are these two the same?
问：这两个是一样的吗？
If not, where do I find the applicaitonDidFinishLaunching function?
如果没有，我在哪里可以找到 applicaitonDidFinishLaunching 函数？

Per the Apple documentation:
根据 Apple 文档：
applicationDidFinishLaunching:
Tells the delegate when the application has finished launching.
当应用程序完成启动时告诉委托。
-(void)applicationDidFinishLaunching:(UIApplication *)application
This method is used in earlier versions of iOS to initialize the application and prepare it to run. In iOS 3.0 and later, you should use the application:didFinishLaunchingWithOptions:instead.
此方法在早期版本的 iOS 中用于初始化应用程序并准备运行。在 iOS 3.0 及更高版本中，您应该使用application:didFinishLaunchingWithOptions:代替。

These are the same. The options have been added in the 4.0 SDK if I recall correctly.
这些都是一样的。如果我没记错的话，这些选项已添加到 4.0 SDK 中。
Edit: it's been there since 3.0: http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intf/UIApplicationDelegate
编辑：它自 3.0 以来一直存在：http: //developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIApplicationDelegate_Protocol/Reference/Reference.html#//apple_ref/occ/intf/UIApplicationDelegate
