iphone - 在AppDelegate中获取RootView的实例

Question

如何获取 RootViewController 的实例才能使用如下代码:

rootViewController.progressView.progress = 0.7

在应用程序委托(delegate)的 applicationDidFinishLauching 方法中？

Answer 1

这对我有用:

#import "CBAppDelegate.h"
#import "OPStringLocalization.h"

@implementation CBAppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    UIViewController* rootController = [self.window rootViewController];
    [rootController localizeStrings];
    return YES;
}
