我需要在按鈕單擊時顯示來自rootviewcontroller的另一個視圖。我寫了下面的代碼,但它不起作用。任何想法爲什麼?在iOS中不工作呈現模態視圖控制器
在我的應用程序的委託方法我有下面的代碼 -
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
// Override point for customization after application launch.
self.viewController = [[[MainMenuViewController alloc] initWithNibName:@"MainMenuViewController" bundle:nil] autorelease];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
然後在我的mainviewcontroller我有這應該帶我去一個不同類別的按鈕動作,但它什麼都不做。儘管nslog語句起作用,但按鈕操作仍在工作。有任何想法嗎?
LoginViewController * loginViewController = [[LoginViewController alloc]initWithNibName:@"LoginViewController" bundle:nil];
[self.modalViewController presentModalViewController:loginViewController animated:YES];
NSLog(@"HE::P");
這是什麼'modalViewController'財產?不應該是'[self presentModalViewController ...]'? – albertamg 2012-07-13 15:31:40
