如何在iPad中顯示和隱藏所選表格行索引的視圖？

我在iPad應用程序中使用一個表格和一個UIview。我想在第二個視圖中顯示table的選定行索引中的不同選項。應用程序用戶界面附加在這裏。我的代碼片段是這樣的： -如何在iPad中顯示和隱藏所選表格行索引的視圖？

- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
NSUInteger row=indexPath.row; 

UILabel *lblName, *lblUserName, *lblOldPassword, *lblCreditCardDetails, *lblNewPassword; 

UITextField *txtName, *txtUserName, *txtOldPassword, *txtNewPassword, *txtCreditCardDetails; 

UIButton *btnsaveprofile, *btnSavePassword, *btnSaveCreditCardDetails; 

UIView *subView =[[UIView alloc] initWithFrame:CGRectMake(321, 0, 448, 980)]; 
[viewDetail addSubview:subView]; 

if (row==0) { 

    [subView removeFromSuperview]; 

    UIView *subView =[[UIView alloc] initWithFrame:CGRectMake(0, 0, 448, 980)]; 
    [viewDetail addSubview:subView]; 

    lblName =[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 140, 40)]; 
    [email protected]"Name"; 
    [lblName setBackgroundColor:[UIColor clearColor]]; 
    [subView addSubview:lblName]; 
    [lblName release]; 

    txtName =[[UITextField alloc] initWithFrame:CGRectMake(141, 0, 200, 40)]; 
    txtName.borderStyle=UITextBorderStyleRoundedRect; 
    [subView addSubview:txtName]; 

    lblUserName =[[UILabel alloc] initWithFrame:CGRectMake(0, 60, 140, 40)]; 
    [email protected]"User Name"; 
    [lblUserName setBackgroundColor:[UIColor clearColor]]; 
    [subView addSubview:lblUserName]; 
    [lblUserName release]; 


    txtUserName =[[UITextField alloc] initWithFrame:CGRectMake(141, 60, 200, 40)]; 
    txtUserName.borderStyle=UITextBorderStyleRoundedRect; 
    [subView addSubview:txtUserName]; 


    btnsaveprofile =[[UIButton alloc] initWithFrame:CGRectMake(100, 160, 100, 40)]; 
    [btnsaveprofile setTitle:@"Save" forState:UIControlStateNormal]; 
    [btnsaveprofile addTarget:self action:@selector(btnSaveProfile) forControlEvents:UIControlEventTouchUpInside]; 
    [subView addSubview:btnsaveprofile]; 


}   
if (row==1) { 

    [subView removeFromSuperview]; 

    UIView *subView1 =[[UIView alloc] initWithFrame:CGRectMake(0, 0, 448, 980)]; 
    [viewDetail addSubview:subView1]; 

    lblOldPassword =[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 140, 40)]; 
    [email protected]"Old Password"; 
    [lblOldPassword setBackgroundColor:[UIColor clearColor]]; 
    [subView1 addSubview:lblOldPassword]; 


    txtOldPassword =[[UITextField alloc] initWithFrame:CGRectMake(141, 0, 200, 40)]; 
    txtOldPassword.secureTextEntry=YES; 
    txtOldPassword.borderStyle=UITextBorderStyleRoundedRect; 
    [subView1 addSubview:txtOldPassword]; 


    lblNewPassword =[[UILabel alloc] initWithFrame:CGRectMake(0, 60, 140, 40)]; 
    [email protected]"New Password"; 
    [lblNewPassword setBackgroundColor:[UIColor clearColor]]; 
    [subView1 addSubview:lblNewPassword]; 


    txtNewPassword =[[UITextField alloc] initWithFrame:CGRectMake(141, 60, 200, 40)]; 
    txtNewPassword.secureTextEntry=YES; 
    txtNewPassword.borderStyle=UITextBorderStyleRoundedRect; 
    [subView1 addSubview:txtNewPassword]; 


    btnSavePassword =[[UIButton alloc] initWithFrame:CGRectMake(100, 160, 100, 40)]; 
    [btnSavePassword setTitle:@"Save" forState:UIControlStateNormal]; 
    [btnSavePassword addTarget:self action:@selector(btnNavigationBarClicked) forControlEvents:UIControlEventTouchUpInside]; 
    [btnSavePassword setBackgroundImage:[UIImage imageNamed:@"btn_signin_bg.png"] forState:UIControlStateNormal]; 
    [subView1 addSubview:btnSavePassword]; 


} 
if (row==2) { 

    [subView removeFromSuperview]; 


    UIView *subView =[[UIView alloc] initWithFrame:CGRectMake(0, 0, 448, 980)]; 
    [viewDetail addSubview:subView]; 

    lblCreditCardDetails =[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 180, 40)]; 
    [email protected]"Credit Card Details"; 
    [lblCreditCardDetails setBackgroundColor:[UIColor clearColor]]; 
    [subView addSubview:lblCreditCardDetails]; 
    [lblCreditCardDetails release]; 

    txtCreditCardDetails =[[UITextField alloc] initWithFrame:CGRectMake(181, 0, 200, 40)]; 
    txtCreditCardDetails.secureTextEntry=YES; 
    txtCreditCardDetails.borderStyle=UITextBorderStyleRoundedRect; 
    [subView addSubview:txtCreditCardDetails]; 
    [txtCreditCardDetails release]; 


    btnSaveCreditCardDetails =[[UIButton alloc] initWithFrame:CGRectMake(100, 130, 100, 40)]; 
    [btnSaveCreditCardDetails setTitle:@"Save" forState:UIControlStateNormal]; 
    [btnSaveCreditCardDetails setBackgroundImage:[UIImage imageNamed:@"btn_signin_bg.png"] forState:UIControlStateNormal]; 
    [btnSaveCreditCardDetails addTarget:self action:@selector(btnSaveCreditCard) forControlEvents:UIControlEventTouchUpInside]; 
    [subView addSubview:btnSaveCreditCardDetails]; 
    [btnSaveCreditCardDetails release]; 
    btnSaveCreditCardDetails.hidden=YES; 

}

}

我用這個代碼，但不幸的是它與以前的觀點重疊。

我的問題是如何避免重疊或以什麼方式隱藏以前的意見。

只是使用普通視圖和didselectrow使用快速enumaration像（UIview *在viewDetail中查看）{[view removeFromSuperView];}然後添加你自定義標籤文本到viewDetail – krishh 2013-05-02 09:35:08

我編輯你的代碼，你需要添加其他意見，只是用下面的代碼之前刪除的DetailView的所有子視圖：

- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{ 
NSUInteger row=indexPath.row; 
UILabel *lblName, *lblUserName, *lblOldPassword, *lblCreditCardDetails, *lblNewPassword; 
UITextField *txtName, *txtUserName, *txtOldPassword, *txtNewPassword, *txtCreditCardDetails; 
UIButton *btnsaveprofile, *btnSavePassword, *btnSaveCreditCardDetails; 
//UIView *subView =[[UIView alloc] initWithFrame:CGRectMake(321, 0, 448, 980)]; 
//[viewDetail addSubview:subView]; 

//Remove all subviews of viewDetail 

    for (UIView *subviews in viewDetail.subviews) 
    { 
     [subviews removeFromSuperview]; 
    } 

if (row==0) { 
// [subView removeFromSuperview]; 
    UIView *subView =[[UIView alloc] initWithFrame:CGRectMake(0, 0, 448, 980)]; 
    [viewDetail addSubview:subView]; 
    lblName =[[UILabel alloc] initWithFrame:CGRectMake(0, 0, 140, 40)]; 
    [email protected]"Name"; 
    [lblName setBackgroundColor:[UIColor clearColor]]; 
    [subView addSubview:lblName]; 
    [lblName release]; 
    txtName =[[UITextField alloc] initWithFrame:CGRectMake(141, 0, 200, 40)]; 
    txtName.borderStyle=UITextBorderStyleRoundedRect; 
    [subView addSubview:txtName]; 
    lblUserName =[[UILabel alloc] initWithFrame:CGRectMake(0, 60, 140, 40)]; 
    [email protected]"User Name"; 
    [lblUserName setBackgroundColor:[UIColor clearColor]]; 
    [subView addSubview:lblUserName]; 
    [lblUserName release]; 
    txtUserName =[[UITextField alloc] initWithFrame:CGRectMake(141, 60, 200, 40)]; 
    txtUserName.borderStyle=UITextBorderStyleRoundedRect; 
    [subView addSubview:txtUserName]; 
    btnsaveprofile =[[UIButton alloc] initWithFrame:CGRectMake(100, 160, 100, 40)];

謝謝Bhupendra ....它的工作.... !!!! :-) – 2013-05-02 09:45:16

如果它的工作，那麼你可以接受的答案並將其標記:)） – Bhupendra 2013-05-02 10:05:41

是的，我已經這樣做了..... – 2013-05-02 10:25:50

嘗試下面的代碼代替[子視圖removeFromSuperview];

[[viewDetail subviews] makeObjectsPerformSelector:@selector(removeFromSuperview)];
