在didFinishLaunchingWithOptions中创建的控制器中更改NSString的值并重新加载该控制器

Question

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{


if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
{
CGSize result = [[UIScreen mainScreen] bounds].size;
if(result.height == 480)
{
    // iPhone Classic
    NSLog(@"iPhone 4");
}
if(result.height == 568)
{
    // iPhone 5
    NSLog(@"iPhone 5");
}
}

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

SideMenuViewController *leftMenuViewController = [[SideMenuViewController alloc] init];



ContainerOfSideMenuByVeerViewController *container = [ContainerOfSideMenuByVeerViewController
                                                  containerWithCenterViewController:[self navigationController]
                                                  leftMenuViewController:leftMenuViewController];

self.window.rootViewController = container;
[self.window makeKeyAndVisible];

return YES;

}

我想更改leftMenuViewController中存在的NSString的值并重新加载它，以便我可以根据新数据更改逻辑。

我想在每个控制器中更改NSString，但我无法做到，因为leftMenuViewController在didFinishLauchingWithOption中启动，只加载一次。

我该怎么做？

Answer 1

您可以在refresh中制作leftMenuViewController方法，或在property中制作NSString。 定义SideMenuViewController *leftMenuViewController in Appdelegate file and make it属性,使用以下方法合成it. Now you are able to refresh your leftMenuViewController with your NSString`：

AppDelegate *appDelegate = [UIApplication sharedApplication];
[appDelegate.leftMenuViewController refresh:yourStr];
