search suggestion selection requires two taps

[bvrr557]

Search suggestion result selection is not working on first tap. The didSelectRowAtIndexPath() is not called on first tap. But works fine on second tap.
Single tap worked fine when I commented the below, but not sure of the side effects.
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboradFrameDidShow:) name:UIKeyboardDidShowNotification object:nil];
