UITextField Uniqueness in UITableViewCell

Question

在UITableViewCell中，单元格中有多个uitextfield ，那么如何识别uitextfield委托方法中除标签属性之外的哪个文本字段会产生动作？

Answer 1

Is your textfield is a member of a class? or created inside the method. If your textfield is a member variable you can check it by :

- (void) textFieldDidEndEditing:(UITextField *)textField
{
if ( [textfield isEqual:m_yourTextField] )
{

}
}

This way, you don't need to use tags. :D

Answer 2

您可以在cellForRowAtIndexPath:分配特定文本字段的标记值cellForRowAtIndexPath:例如分配indexPath.row）作为标记值，​​并将其条件放入uitextfield委托方法中

Answer 3

Check the below code:

In your cellForRowAtIndexPath

[cell.yourtextField setTag:indexPath.row];

[cell.yourtextField addTarget:self action:@selector(textClicked:)
        forControlEvents:UIControlEventTouchUpInside];

Then

-(void)textClicked:(UITextFiled*)txt
{
    NSLog(@"viewbuttonClicked:%ld",(long int)[txt tag]);


}

Answer 4

- (void) textFieldDidEndEditing:(UITextField *)textField{
   if (textField == _txtPhone) {
     //Phone text field
    }
}
