在 UITableViewCell 中有一个 UITextField [英] Having a UITextField in a UITableViewCell

问题描述

我现在已经尝试这样做了几天，并且在阅读了大量尝试这样做的人的消息后，我仍然无法在我的一些 UITableViewCells，就像在这个例子中:

I'm trying to do that for a couple of days now, and after reading tons of messages of people trying to do that too, I'm still unable to have a fully working UITextField in some of my UITableViewCells, just like in this example:

我的表单可以正常工作但文本不可见(尽管我将其颜色设置为蓝色)，当我单击它时键盘会进入该字段并且我无法正确实现键盘事件.我尝试了一系列来自 Apple 的示例(主要是 UICatalog，其中有一个类似的控件)但它仍然无法正常工作.

Either I have the form working but the text is not visible (although I set its color to blue), the keyboard goes on the field when I click on it and I haven't been able to correctly implement the keyboard events. I tried with a bunch of examples from Apple (mainly UICatalog, where there is a kinda similar control) but it's still not working correctly.

有人可以帮助我(以及所有试图实现此控件的人)并在 UITableViewCell 中发布一个 UITextField 的简单实现吗?>

Can somebody help me (and all the people trying to realize this control) and post a simple implementation of a UITextField in a UITableViewCell, that works fine?

推荐答案

试试这个.对我来说就像一个魅力(在 iPhone 设备上).我曾经将此代码用于登录屏幕.我将表格视图配置为有两个部分.你当然可以去掉部分条件.

Try this out. Works like a charm for me (on iPhone devices). I used this code for a login screen once. I configured the table view to have two sections. You can of course get rid of the section conditionals.

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:kCellIdentifier];
if (cell == nil) {
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault 
                                   reuseIdentifier:kCellIdentifier] autorelease];
    cell.accessoryType = UITableViewCellAccessoryNone;

    if ([indexPath section] == 0) {
        UITextField *playerTextField = [[UITextField alloc] initWithFrame:CGRectMake(110, 10, 185, 30)];
        playerTextField.adjustsFontSizeToFitWidth = YES;
        playerTextField.textColor = [UIColor blackColor];
        if ([indexPath row] == 0) {
            playerTextField.placeholder = @"[e-mail]";
            playerTextField.keyboardType = UIKeyboardTypeEmailAddress;
            playerTextField.returnKeyType = UIReturnKeyNext;
        }
        else {
            playerTextField.placeholder = @"Required";
            playerTextField.keyboardType = UIKeyboardTypeDefault;
            playerTextField.returnKeyType = UIReturnKeyDone;
            playerTextField.secureTextEntry = YES;
        }       
        playerTextField.backgroundColor = [UIColor whiteColor];
        playerTextField.autocorrectionType = UITextAutocorrectionTypeNo; // no auto correction support
        playerTextField.autocapitalizationType = UITextAutocapitalizationTypeNone; // no auto capitalization support
        playerTextField.textAlignment = UITextAlignmentLeft;
        playerTextField.tag = 0;
        //playerTextField.delegate = self;

        playerTextField.clearButtonMode = UITextFieldViewModeNever; // no clear 'x' button to the right
        [playerTextField setEnabled: YES];

        [cell.contentView addSubview:playerTextField];

        [playerTextField release];
    }
}
if ([indexPath section] == 0) { // Email & Password Section
    if ([indexPath row] == 0) { // Email
        cell.textLabel.text = @"Email";
    }
    else {
        cell.textLabel.text = @"Password";
    }
}
else { // Login button section
    cell.textLabel.text = @"Log in";
}
return cell;    
}

结果如下:
