valueForKey: @"_clearButton"

[mahmutsahinn]

Hi,

I have a US2ValidatorTextField and i want to change clear button image.

@Property(nonatomic,strong) US2ValidatorTextField *txtSearch;

in viewDidload method;

UIButton *clearButton = [self.txtSearch valueForKey:@"_clearButton"]; [clearButton setImage:[UIImage imageNamed:@"icon_textbox_close"] forState:UIControlStateNormal]; [clearButton setImage:[UIImage imageNamed:@"icon_textbox_close"] forState:UIControlStateHighlighted];

This code works fine but sometimes it gives crash for valueforundefined key.
I had to get into try catch block. I dont understand root causes this error.
