如何在新視圖中顯示方法的結果？

Question

我已經創建了一個應用程序，該應用程序在輸入用戶信息後向登錄頁面開始，並向服務器發送GET。使用響應值我動態地創建按鈕，標題等。一切正常，但在發送GET並使用JSON響應之後，我的按鈕正在與登錄頁面在同一視圖上創建。我也想創建一個新視圖並在該視圖上創建按鈕。由於我使用用戶信息中的一些參數，我需要使用MainViewController在同一個類中創建視圖（在我的情況下，它的格式爲BNT_1ViewController），但我無法弄清楚如何處理這種情況。我也在分享代碼，也許有幫助。
第二個問題，使用此代碼我的按鈕只是向下移動，但我需要兩行按鈕。我怎樣才能改變x軸按鈕的位置？我改變這些值，但是整列變化，即使我想只是放置兩個按鈕在同一行，所有的結構取代了..

-(IBAction)Accept:(id)sender 
    { userName=[[NSString alloc] initWithString:userNameField.text ]; 
     [userNameField setText:userName]; 
     NSUserDefaults *userNameDef= [NSUserDefaults standardUserDefaults]; 
     [userNameDef setObject:userName forKey:@"userNameKey"]; 
     password =[[NSString alloc] initWithString:passwordField.text]; 
     [passwordField setText:password]; 
     NSUserDefaults *passDef=[NSUserDefaults standardUserDefaults]; 
     [passDef setObject:password forKey:@"passwordKey"]; 
     serverIP=[[NSString alloc] initWithString: serverField.text]; 
     [serverField setText:serverIP]; 
     NSUserDefaults *serverDef=[NSUserDefaults standardUserDefaults]; 
     [serverDef setObject:serverIP forKey:@"serverIPKey"]; 
     [userNameDef synchronize]; 
     [serverDef synchronize]; 
     [passDef synchronize];

以下是您查詢的答案，也許它會幫助你 - 1.我也想創建一個新視圖並在該視圖上創建按鈕。 爲此，您可以創建新的視圖控制器，並在收到響應後推送該視圖控制器。您也可以將響應從一個控制器浮動到其他控制器。 2.第二個問題，使用此代碼我的按鈕只是向下移動，但我想要兩行按鈕 您需要正確設置按鈕框架，然後才能完美工作。
