如何在IBAction中读取UITextField值。我正在以编程方式创建UITextField [英] How can I read UITextField value in an IBAction. I'm creating UITextField programmatically

问题描述

如何在 IBAction 中读取 UITextField 值？我正在以编程方式创建 UITextField 。所以我不能使用Xcode设置 @property 和 @synthesize 。生成 UITextField 的代码如下：

How can I read UITextField value in an IBAction? I'm creating UITextField programmatically. So I can't set @property and @synthesize using Xcode. The code to generate UITextField is as follows:

for(i=0; i<[fieldName count]; i++)
{
    UITextField *name = [fieldName objectAtIndex:i];
    frame = CGRectMake(fromLeft, fromTop, totalWidth, totalHeight);
    name = [[[UITextField alloc] initWithFrame:frame] autorelease];
    name.borderStyle = UITextBorderStyleRoundedRect;
    name.returnKeyType = UIReturnKeyDone;
    //name.placeholder = [fieldName objectAtIndex:i];
    name.autocapitalizationType = UITextAutocapitalizationTypeWords;
    name.adjustsFontSizeToFitWidth = TRUE;
    name.keyboardType = UIKeyboardTypeDefault;

    [name addTarget:self action:@selector(doneEditing:) forControlEvents:UIControlEventEditingDidEndOnExit];   
    [scroller addSubview:name];
    fromTop = fromTop + 40;
}

现在我想在按钮点击中读取每个文本框的值（ IBAction为）。有人可以帮我吗？

Now I want to read values of each textbox in a button click (IBAction). Can anyone help me please?

推荐答案

你可以使用这样的东西来遍历所有 UITextFields 是 self.view 的子视图，并将其文本添加到 NSMutableArray ：

You could use something like this to loop through all UITextFields that are subviews of self.view and add their text to a NSMutableArray:

for (UITextField *field in self.view.subviews) {
    if ([field isKindOfClass:[UITextField class]]) {
        if ([[field text] length] > 0) {
            [someMutableArray addObject:field.text];
        }
    }
}
