可可:将参数传递给NSApplicationDelegate [英] Cocoa: Pass arguments to NSApplicationDelegate

问题描述

我已经创建了简单的Cocoa应用程序(Mac OS X 10.6)，并且出现了入口点:

I have created the simple Cocoa application (Mac OS X 10.6) and there have appeared the entry point:

int main(int argc, char *argv[])
{
    return NSApplicationMain(argc,  (const char **) argv);
}

和AppDelegate虚拟:

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    // how to get argc and argv?
}

和其他一些.如何将argc和argv正确传递给AppDelegate?

and some other. How could I pass the argc and argv to my AppDelegate right way?

推荐答案

使用+[NSProcessInfo processInfo]和-[NSProcessInfo arguments].

在您的应用程序委托中，

In your application delegate,

- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
    NSArray *args = [[NSProcessInfo processInfo] arguments];
    // use -objectAtIndex: to obtain an element of the array
    // and -count to obtain the number of elements in the array
}
