如果我想在运行时通过另一个文件名 MainWindow2.xib 更改它,我已经在 .plist 文件中添加了我的 MainWindow.xib 文件名。我们如何通过代码更改它?

你不能,因为info.plist
应用程序包是只读的。您将不得不通过代码来完成。
从 info.plist 中删除所有主窗口,这是一个示例:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
UIViewController *rootViewController = nil;
// Override point for customization after application launch.
if (YES) { //You check here
rootViewController = [[SomeViewController alloc] initWithNibName:@"SomeViewController" bundle:nil];
} else {
rootViewController = [[OtherViewContoller alloc] initWithNibName:@"OtherViewContoller" bundle:nil];
}
self.window.rootViewController = rootViewController;
[self.window makeKeyAndVisible];
return YES;
}
中的main.m
:
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
int main(int argc, char *argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
