  1. POSetting text to the UISearchBar when its firstresponder with controller change works weird
    text
    copied!<p>In my app i have <code>UITextField</code> on view of VC1(<code>UIViewController</code>). When i change text in textfield i call pushing of another controller VC2 with <code>UISearchBar</code> on its view. After pushing im assigning <code>UISearchBar</code> text to the textfield text from VC1.</p> <p>On xib my textfield already have some text "Test string".</p> <p>When I'm append VC1 textfield with any char - VC2 pushing and text on searchbar is normal.</p> <p>But when I'm press backspace key on iPhone keyboard - VC2 pushed and text on searchfield start deleting char by char, while whole string not been empted. It happend because delegate method calls recursively.</p> <p>How to fix that behaviour of <code>UISearchBar</code>? I mush to have searchbar active with keyboard opened when VC2 appears! It's main condition. Sure, if i'll remove <code>[self.searchBar becomeFirstResponder]</code> all will works fine.</p> <p>Some code here:</p> <pre><code>@implementation ViewController1 - (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string { NSString * resultString = [textField.text stringByReplacingCharactersInRange:range withString:string]; ViewController2 * vc2 = [ViewController2 new]; [self.navigationController pushViewController:vc2 animated:YES]; [vc2 loadText: resultString]; return NO; } @end @implementation ViewController2 - (void) viewWillAppear:(BOOL)animated { [super viewWillAppear:animated]; [self.searchBar becomeFirstResponder]; } - (void) loadText: (NSString *) text { self.searchBar.text = text; } @end </code></pre> <p>Sample source code of the problem: <a href="http://yadi.sk/d/NJmTLot73_vrE" rel="nofollow">http://yadi.sk/d/NJmTLot73_vrE</a></p>
