selectedTextRange return nil in UISearchbar iOS - ios

Question

I have aUISearchBar, I get theUITextfield in it and then I want to set selected Text range but it's always return nil. This is my code:
UITextField *searchField = [self.searchBar valueForKey:#"_searchField"];
[searchField becomeFirstResponder]; // focus to this searchfield
And I fill in the text:
self.searchBar.text = #"This is text";
And checked if theUITextField text is filled in and it is. Still, all the methods regardingUITextPosition andUITextRange return nil:
UITextRange *selectedRange = [searchField selectedTextRange]; //selectedRange = nil
UITextPosition *newPosition = [searchField positionFromPosition:selectedRange.start offset:addressToComplete.street.length]; //newPosition = nil
UITextRange *newRange = [searchField textRangeFromPosition:newPosition toPosition:newPosition]; //newRange = nil
My code is wrong something?

Have you tried Logging UITextField *searchField? its nil from the looks of it.. i think your code is supposed to be..
(UITextField *)[self.searchBar valueForKey:#"_searchField"]
([after trying your code] OooOoKayyy.. it works.. hahaha..) By the way this is how i get UITextField inside searchBar..
for (id object in [[[self.searchBar subviews] objectAtIndex:0] subviews])
{
if ([object isKindOfClass:[UITextField class]])
{
UITextField *searchField = (UITextField *)object;
break;
}
}
First i tried what you have which is:
UITextField *searchField = (UITextField *)[searchBar valueForKey:#"_searchField"];
searchBar.text = #"This is text";
// and logging your searchField.text here.. returns nil/empty..
and i tried rearranging it like this...
searchBar.text = #"This is text";
UITextField *searchField = (UITextField *)[searchBar valueForKey:#"_searchField"];
NSLog(#"searchFields.text :%#", searchField.text);
again i tried your code under -(void)viewDidLoad but no good, yeah it is always nil as you said.. now it looks like this..
- (void)viewDidLayoutSubviews
{
[super viewDidLayoutSubviews];
searchBar.text = #"This is text"; // not important
UITextField *searchField = [searchBar valueForKey:#"_searchField"];
[searchField becomeFirstResponder];
UITextRange *selectedRange = [searchField selectedTextRange]; //selectedRange = not nil anymore
NSLog(#"searchField.text :%# -> selectedRange :%#\n\n" , searchField.text, selectedRange);
}
//i've also tried it inside uibutton's event and i worked .. >.<
i programmatically selectedTextRange(for example purposes) and probably it something to do with the xibs autolayout or something (weird i dont experience it) but there it is, try it.. :)
i hope i've helped you..
Happy coding.. Cheers!
