使用xcode中的單個按鈕顯示和隱藏標籤文本框

-1

當使用一個按鈕執行操作時，需要顯示和隱藏一些標籤和文本框。詳細我想使用單個UIButton執行兩個操作我嘗試了下面的代碼，但它只執行一個操作。我可以使用相同的按鈕顯示標籤，但是當我再次點擊時，我無法隱藏它。使用xcode中的單個按鈕顯示和隱藏標籤文本框

-(IBAction)changePassword:(id)sender { 
    if ([sender tag]==0) 
    { 
     newPasswordLbl.hidden=NO; 
     oldPasswordLbl.hidden=NO; 
     confirmPasswordLbl.hidden=NO; 
     newPassword.hidden=NO; 
     oldPassword.hidden=NO; 
     confirmPassword.hidden=NO; 
     submit.hidden=NO; 
     settings.hidden=NO; 
     connection.hidden=YES; 
     openTrades.hidden=YES; 
     closedTrades.hidden=YES; 
    } 
    else if([sender tag]==1) 
    { 
     newPasswordLbl.hidden=YES; 
     oldPasswordLbl.hidden=YES; 
     confirmPasswordLbl.hidden=YES; 
     newPassword.hidden=YES; 
     oldPassword.hidden=YES; 
     confirmPassword.hidden=YES; 
     submit.hidden=YES; 
     settings.hidden=NO; 
     connection.hidden=YES; 
     openTrades.hidden=YES; 
     closedTrades.hidden=YES; 
    } 


}

我已經使用與發件人標籤兩個按鈕在上面的代碼，但犯規的作品出來 – gopinath

有啥不加工。詳細解釋（編輯問題） – DHEERAJ

哎！我的錯誤對不起朋友 – gopinath

在changePassword方法後更改按鈕的標籤。

-(IBAction)changePassword:(id)sender { 

    UIButton pressedButton = (UIButton *) sender; 
    if ([pressedButton tag]==0) 
    { 
     // change your buttons tag here. 
     pressedButton.tag = 1; 
     // change the visibility of the buttons. 
    } 
    else if([pressedButton tag]==1) 
    { 
     // change your buttons tag here. 
     pressedButton.tag = 0;  
     // change the visibility of the buttons. 
    } 
}

我不能像sender.tag = 1 asign上面它拋出一個錯誤（屬性標籤找不到強類型對象的對象） – gopinath

指定發件人到UIButton，然後你將有標籤屬性，然後你可以更改。 –

是的，它解決了！我明白了@Pradeep做得好！謝謝 – gopinath

-(IBAction)changePassword:(UIButton *) sender {  
    sender.selected = !sender.selected;  
    if (sender.selected) {  
     // write your code here for tag 0  
     } else {  
     // write your code here for tag 1  
    }  
}
