IOS頁面跳轉的方法

標籤：

在頁面跳轉時，若想用pushViewController，則必須在AppDelegate設定UINavigationController，否則pushViewController無效。
並且用pushViewController從A跳往B後，在B頁面內建“Back”按鈕返回上一頁。類似於

這樣設定，在AppDelegate中

 1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 2     self.window = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen] bounds]]; 3     UIViewController *controllerA = [[ViewController alloc]init]; 4     UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:controllerA]; 5      6     self.window.rootViewController = nav; 7     [self.window makeKeyAndVisible]; 8      9     return YES;10 }

在controllerA中的跳轉頁面方法中這樣寫

-(void)turnToOtherController{    ControllerB *controllerB = [[ControllerB alloc]init];    [self.navigationController pushViewController:controllerB animated:YES];}

這樣，導航條就會一直存在。若不想要導航條，那麼在AppDelegate這樣寫

1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {2     self.window = [[UIWindow alloc]initWithFrame:[[UIScreen mainScreen] bounds]];3     UIViewController *controllerA = [[ViewController alloc]init];4     self.window.rootViewController = controllerA;5     [self.window makeKeyAndVisible];6     7     return YES;8 }

而下面這種方法是通用的，無需設定rootViewController。

[self presentViewController:mainView animated:YES completion:nil];//controller內建的屬性

下面的則需要

[self.navigationController pushViewController:mainView animated:YES];//必須在AppDelegate設定UINavigationController，否則pushViewController無效。//並且使用pushViewController後，在B頁面，會內建一個“Back”按鈕返回上一頁。
