I have a requirement where i have a textfield in a view. When i want to open the view by switching the tab(TabBased Application),first time when the view is loaded the keyboard appears because i loadview method is called. But when i switch to tab2 and again switch to tab1 again, load view is not called. I want the keyboard to appear everytime i open the tab1 page.. Please Help Me.

A:
Use -viewWillAppear: in your view controller to send your text field a -becomeFirstResponder message, e.g.:
- (void) viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[myTextField becomeFirstResponder];
}

You code should work, assuming all the objects are instantiated and wired up. Try adding an `NSLog` statement to verify that `-viewWillAppear:` gets called. Also make sure `searchForProduct` isn't `nil` and/or that it is hooked up properly if you're using Interface Builder for your view.

searchForProduct is not released.. It contains the memory allocation... The Problem is viewWillAppear Method is never called...

What class are you putting `-viewWillAppear:` into? Are you putting it into a `UIViewController` subclass or a `UIView` subclass or some other subclass?

If you're putting it into a view controller, then it should get called. Put an `NSLog` statement in the `-viewWillAppear:` method and watch the Console. If you're not getting a log statement printed to the Console, then something else is wrong with your application unrelated to this.
