Question

Here is the UI…(I know it is ugly…) The orange is a view, and the blue is the table, and the gray one is the table cell, lastly, the red is a textfield in a table cell. My question is simple, I just wanna to know the red text field position… Seems the table cell may move up and down, so, the position can be changed. So, I don’t need to dynamic update the text field position, I just need the position when the user click the text field, any ideas? Thanks.

Answer 1

you can make use of convetrPoint methods that can be used on an UIView or its derived classes

- (CGPoint)convertPoint:(CGPoint)point toView:(UIView *)view
- (CGPoint)convertPoint:(CGPoint)point fromView:(UIView *)view

in you case, you’ll need to do this:

- (void)textFieldDidBeginEditing(UITextField *)textField 
{
     CGPoint textFieldOriginInTableView = [textFiled convertPoint:textField.frame.origin toView:tableView];
     //or if you want it relative to the orangeView, your toView should be the orangeView
}
