Issue with UIView loaded from nib file - ios

Question

I am developing an application with multiple views. I have a template for an image gallery which I have created in a xlib file. This view will be loaded as a single page in a scroll view. I am able to get the view loaded multiple time from xlib with the following:
- (void)registerForKeyboardNotifications
{
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWasShown:)
name:UIKeyboardDidShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(keyboardWillBeHidden:)
name:UIKeyboardWillHideNotification object:nil];
}
- (id)initWithFrame:(CGRect)frame
{
self = [[[NSBundle mainBundle] loadNibNamed:#"GSEstimateView" owner:self options:NULL] lastObject];
self.commentText.delegate = self;
self.scrollView.delegate = self;
self.commentText.delegate =self;
[self registerForKeyboardNotifications];
return self;
}
The first issue I am facing is, when the key board is shown the keyboardWasShown: method is getting called for as many UIViews I have created. If I try to load the keyboard from the second UIView, I get an exception for invalid selector being called. Is the UIView loaded from a nib or xlib Singleton? How can I have my UIView instance notified if I load it from nib file?

Hi first I don't recommend to use NSNotification prefer to use protocols like this.
#protocol KeyBoardDelegate <NSObject>
- (void)KeyBoardVisible:(BOOL)op;
#end
And if you have multiples views and if you want to now the view control like this:
*viewDidLoad, viewDidUnload, viewWillDisappear, viewWillAppear, and others *
I recommend use the view of the UIViewController like this.
UIViewControllerCustom *example = [[UIViewControllerCustom alloc] initWithNibName:#"exampleNIB" bundle:[NSBundle mainBundle]];
[self.view addSubview:example.view];
Using this you can take the control of the view of example viewcontroller and use the methods
- (void)viewDidLoad{
[super viewDidLoad];
//When the nib has been loaded.
}
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
//When the view is show.
}
- (void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
//The view is hidden
}
- (void)viewDidUnload{
[super viewDidUnload];
// Release any retained subviews of the main view.
}
And some more methods. :)
