如何在滾動時設置textfield內容？

Question

在我的應用程序中，我在tableview上有37個textfield進行滾動。如果假設我在第一個文本框中輸入了一些值並滾動了表格，那麼在第一個文本文件中輸入的值以及layout可以幫助我輸入值。

下面是我的代碼：

#import "Edit.h" 


@implementation Edit 
@synthesize tableContents,textField,scrollView; 
@synthesize txtUserName,txtFirstName,txtLastName,txtNickName,txtDisplayName,txtEmail,txtWebSite,txtAboutMe,txtNewPassword,txtPasswordAgain; 
@synthesize txtPayPalEmail ,txtActiveMemPk ,txtMemPkExpireDate; 
@synthesize txtBusinessName ,txtAbnAcn ,txtContactName ,txtPhone ,txtFax ,txtMobile ,txtBusinessEmail ,txtFacebookLink ,txtLinkedinLink ,txtMySpaceLink; 
@synthesize txtBlogLink ,txtInstanMessage ,txtWebsite ,txtStreet ,txtCitySuburb ,txtZipCode ,txtState ,txtTradingHour; 
@synthesize txtActiveOfService ,txtTradeOnWeekend ,txtProduct , txtService ,txtPickUpAndDelivery;

{ 
    self = [super initWithStyle:style]; 
    if (self) { 
     // Custom initialization 
    } 
    return self; 
} 

- (void)dealloc 
{ 
    [super dealloc]; 
}

    self.navigationController.navigationBar.tintColor = [UIColor blackColor]; 
    //self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"main-bg.png"]];

            initWithTitle:@"Update"            
            style:UIBarButtonItemStyleBordered 
            target:self 
            action:@selector(update)]; 
    self.navigationItem.rightBarButtonItem = updatebtn; 

    [updatebtn release];

Answer 1

在泰伯維管理文本框創建細胞有點tediuos，如果文本字段的數量是固定的，你可以嘗試使用視圖控制器與37（如果數量是固定的）textfield在滾動視圖。滾動可以通過使用this

如果你仍然想堅持你的想法。然後將textfields的值保存在可變字典中，並在滾動tableview時使用這些數據。

編輯：附加的屏幕快照顯示了一個簡單的視圖，其中包含多個文本框的滾動視圖。您可以創建IBOutlets以將代碼中的這些文本字段鏈接起來，並設置/獲取這些值。如果文本字段的數量太多，則可以使用上述方法向下滾動到最後一個文本字段並管理覆蓋視圖的鍵盤。

Answer 2

這可能是由於細胞的你出隊的財產，

您嘗試通過這樣的

UITableViewCell *cell = [[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:TextCellIdentifier] autorelease]; 
cell.accessoryType= UITableViewCellAccessoryNone; 
cell.selectionStyle=UITableViewCellSelectionStyleNone; 
cell.font = [UIFont fontWithName:@"Helvetica" size:14]; 

Answer 3

需要在.h文件中

到uitextfieldDelegate在.m文件

- (void)textFieldDidEndEditing:(UITextField *)textField { 
if (textField == txtUserName) { 
    self.name = textField.text ; 
} else if (textField == txtNickName) { 
    self.address = textField.text ; 
} else if (textField == txtDisplayName) { 
    self.password = textField.text ; 
} else if (textField == txtEmail) { 
    self.description = textField.text ;  
} 

}
