iphone - 禁用可编辑属性 UITextField

Question

我在禁用UITextField. 我正在尝试将我的文本字段用作组合框，但是当我使用组合框样式时，我的文本是可编辑的。当我设置userInteractionEnabled = NO为阻止编辑时，我看不到我的文本字段作为组合框。我可以为这个问题做些什么？

Answer 1

您在文本字段编辑上显示一个操作表。

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {
    if ([textField isEqual:myTextField]){
       UIActionSheet *actionsheet = [[UIActionSheet alloc] initWithTitle:@"Please select an option" delegate:self cancelButtonTitle:nil destructiveButtonTitle:nil otherButtonTitles:@"Option1", @"Option2", @"Option3", nil];
       [actionsheet showInView:self.view];
       return NO; 
    } 
    return YES;
}

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

[myTextField setText:[actionSheet buttonTitleAtIndex:buttonIndex]];

 }

Answer 2

用这个：

txtBox.editable = NO;

而不是，

txtBox.userInteractionEnabled = NO;

Answer 3

使用这个 UITextField 委托：

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField;

设置返回 NO 并打开您的组合框。

Answer 4

将按钮或其他东西放在 UITextFields 上怎么样。将 Textfields editable 设置为 NO 不是一个好主意，但只会欺骗您的 UI。

Answer 5

I do not think that using uitextfield as combobox is a good solution.The problem is is you disable the userinteraction or make your textview uneditable how would you catch user taps and activate the list?

If i were you i would refer to a button an a small tableview that pops up whe nyou click the button.It is not easy to implement but a more elegant solution.
