无法动态删除UITextField的边框

Question

I want to remove the border of UITextField dynamically.

I tried [stringTextField setBorderStyle:UITextBorderStyleNone];

but nothing happened. Any idea?

Answer 1

Is the TextField already displayed in the view when this happens? If so, you (probably) need to execute the following:

[stringTextField setBorderStyle:UITextBorderStyleNone];
[stringTextField setNeedsDisplay];

in order for the view to redraw the TextField , sans border. Note that there's no guarantee the system will immediately redraw the textField . You're indicating to the system that you'd like the field to be redrawn.

Answer 2

With an existing UITextField I found that this worked:

[textField setEnabled:NO];
[textField setBorderStyle:UITextBorderStyleNone];

while this did not (the border remained in the view):

[textField setBorderStyle:UITextBorderStyleNone];
[textField setEnabled:NO];

Answer 3

Try this ones.

textField.borderStyle = UITextBorderStyleRoundedRect;
textField.borderStyle = UITextBorderStyleNone;
