In iOS 7 searchbar delegate method searchBarTextDidBeginEditingis not being called on second time. When i tap first time on searchbar then it is calling searchBarTextDidBeginEditing this method but when i tap second time then it is not calling its delegate method while it is working good in iOS 6. problem is only with iOS 7
Any help please
In iOS7 used searchBarShouldBeginEditing and my problem is fixed but still i don't know why it is not calling searchBarTextDidBeginEditing in iOS 7 every time. this is called only once but searchBarShouldBeginEditing is called every time

I am using xcode 5 and ios7 simulator. In which textViewShouldBeginEditing called continuously, rather then once when textview becomes active.
Is there any solution to call textViewShouldBeginEditing method only once.
Thank you in advance for your help and consideration.
[textview becomeFirstResponder];
method within textViewShouldBeginEditing will take looping.
It will work in iOS 6 but in iOS 7 need to remove.The responder will automatic to the corresponding textview.
In one of my apps, when I try to edit (type some text) UITextField, UITextView or any other 'text-able' UIControl the cursor just blinks but no characters are typed in except BACKSPACE (possible only when I have some initial text in it), RETURN and switching character types. This goes to all controls across whole application.
Summary:
It happens only from iOS 6.0 (does not occur on iOS 5.x, 4.x neither Simulator or real device)
All delegate methods are fired (shouldBeginEditing: didBeginEditing:) except shouldChangeCharactersInRange:
isFirstResponder flag is behaving set correctly (shouldBeginEditing: logs NO, while didBeginEditing: logs YES correctly). It is also tested using logs that THE firstResponder IS the one already edited.
It repairs itself after any UIAlertView is presented to the user and dismissed. It doesn't matter if this alert is shown on the same screen (UIViewController view) or any other.
I have no idea how to even approach or debug this.
Where should I look for hints? Any experts of tracking responder chain related issues etc.?
How can I track down the UIAlertView's effect on the issue?
Depending on your implementation it's either the makeKeyAndVisible method of the UIWindow class that you forgot to call inside the - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions method of the application delegate or corresponding Visible at Launch flag in your main interface xib file.
Cheers... :)
in my case, there is a 'visible at launch' on the main window, it was unchecked, which works on iOS5 only, needs to check it to make it working on iOS6.
In my situation I had an activity indicator that would pop up over the main window during periods of background activity. In this case the activity indicator view had its own window that was set to UIWindowLevelAlert. I was inadvertently calling makeKeyAndVisible on this window. Later on I would call resignKeyWindow. This used to work on iOS 4 and 5 but no longer worked in iOS 6. I discovered that this was not technically necessary as simply using window.hidden = Y/N worked just as well.
In my case I moved becomeFirstResponder for my UITextField from ViewDidLoad to ViewDidAppear and this solved my problem.
I'm running into a problem where 9 times out of ten, when I call UIAlertView's dismissWithClickedButtonIndex:animated:, the delegate method alertView:willDismissWithButtonIndex: is not called. Is anyone else running into this problem? I'm about to file a bug with Apple but I'm curious to see if anyone else has run into this issue and figured out any workarounds.
To ensure a consistent behavior across iOS4 and 5, you could just remove the UIAlertView's delegate just prior to calling its dismissWithClickedButtonIndex:animated: method, then manually invoke the delegate method. e.g.
- (void)somethingDidHappen {
id<UIAlertViewDelegate> delegate = myAlertView.delegate;
myAlertView.delegate = nil;
// now, we know the delegate won't be called...
[myAlertView dismissWithClickedButtonIndex:0 animated:NO];
// ...so we call it ourselves below
[delegate alertView:myAlertView clickedButtonAtIndex:0];
}
(That code isn't tested, but you get the point.)
Delegates of UI objects are only called when the user performs an action. Apple assumes that when you do something from code, you already know what you're doing and you don't need to be informed. That applies to all delegates (scrolling delegate methods of UIScrollView vs. code-scrolling, Table View manipulation, ...)
Anyway, what button index should the delegate be called with?.. there is no one when you dismiss programmatically
According to Why doesn't dismissWithClickedButtonIndex ever call clickedButtonAtIndex? the problem is that a different method is being called. However, that doesn't explain why you get erratic calls. On the devices I tested the dismiss method gets called correctly, so I only redirect it to the click version.
Maybe you should file a bug with Apple if you continue seeing the erratic behaviour.
There are alertView:clickedButtonAtIndex:, alertView:didDismissWithButtonIndex: and alertView:willDismissWithButtonIndex:. The method that you're referring to (clickedButtonAtIndex:) is only called when the user explicitly taps on a button on your alert view (hence 'clicked').
Programmatic calls via dismissWithClickedButtonIndex:animated: to dismiss the alert does not seem to call alertView:clickedButtonAtIndex:.
So, if you need some behavior to be always triggered upon the dismissal of the alert view—whether it was triggered by the user tapping on a button or triggered programmatically—then using the didDismissWithButtonIndex: and willDismissWithButtonIndex: makes more sense.
my question is that i use ios 4.1 and viewWillAppear is not call when i go via
[self.view addSubView:self.mySecondView.view];
then and in the first view i alloc second view on ViewDidLoad .. i just want to call ViewWillApear on Second View because want to do the task dynamic.
is their some thing alternative... because InitWithNibName method also fire when alloc and init occur.. i want to fire some method when i add to that view.
Thanks
The same issue is discussed before,Just go through below SO links.

here is the tutorial post

I wrote a small application and tried running it on my device. I had written a function and tried calling it in application did finish launching. It didn't get called every time I ran my app from the homescreen. Then someone told me that applicationdidFinishLaunching doesn't get called every time you launch your app from the homescreen. I then tried calling it in viewDidLoad and later in viewWillAppear methods but it never got called after the first launch. So finally I had to put a UIButton and call the function on buttonClick after which it finally worked. Can someone tell me why it happened?
You probably are testing on iOS 4 which supports multitasking, where apps aren't exited but suspended. You should read a little about app lifecycle in iOS4
