- (IBAction)updateText:(id)sender {
	if([txtName.text length] == 0) {
		lblHello.text = @"Please enter your name";
	} else {
		lblHello.text = [[NSString alloc] initWithFormat:@"Hello %@!", txtName.text];
	}
	[sender resignFirstResponder];
}

But then you use : “lblHello.text = text” and not “self.lblHello.text = text”.
“self” is not mandatory if we want to call the property ? else we call the ivar ?

Thank you for your help.

Xcode : Create an IBAction method in our Controller class that will cause the UITextField to release his grab of the keyboard. Put the following line in your .h file:

-(IBAction)textFieldDoneEditing:(id)sender;

IB : Connect the UITextField’s DidEndOnExit event to our new IBAction method
IB : Set the Keyboard>Type property of the UITextField to Done
Xcode: put this in your .m file:

-(IBAction)textFieldDoneEditing:(id)sender{
[sender resignFirstResponder];
}

In interface Builder, you need to connect your Did End On Exit event to this method.

gl

-(BOOL)hideKeyboard:(UITextField *)textField{
[textField resignFirstResponder];
return YES
}

and in the Interface Builder view, I chose the Textfield, click and drag the circle of the delegate to the File’s owner. But the keyboard still doesn’t hide after I click Display. So can you help me with this? or did I miss something in the .h file. From my experience, I think I need to declare something in the .h which it can be recognized in the .m file ( I used to work code with C++ so I think these are the same ). Can you help me

Thanks

Thanks!

Please only RELEASE if you have ALLOC.

If your if-statement is true… you don’t ALLOC…. but you *STILL* free the memory.

Ugh.

- Highlight “File’s Owner” in Interface Builder
- Click on “File->Read Class Files…” from the menu bar
- Navigate to your view controller header file (ViewBasedViewController.h) and click “Open”

You can now make your connections as the tutorial describes

Thanks for the tutorials Brandon!

Thanks for the tutorials, they are really nice explained and run smoothly. Thanks a lot!

I don’t know if this was a problem with me or something that has changed with the SDK, but I had to manually link the “view” to get this tutorial to work.

In the Interface Builder, under Connections, drag from the circle to the right of “view” to “File’s Owner” and select “view”.

Prior to doing that, the app would start up and instantly close. It was only by comparing what I had to the downloaded xib file that I found the issue.

I am VERY new to the Mac and thus am making all sorts of noob mistakes, one of them being:

I dragged Xcode to the desktop and now, boom, it doesn’t work.

This problem needs to be resolved before I can go further, any ideas?

Thanks again for the great walkthroughs!

I was trying to set things before “viewDidLoad” had actually occurred…

How silly

I’ve created a view with a NIB called “Search Results NIB”, and it has a label on it. I connected to Files Owner to Search_Results_View (the view controller), connected the View I created to the File’s Owner, and then connected label I created to the File’s Owner (with a variable named “filterBy”).

So then in my app, when the user selects an element in a table, it creates a “Search Results View” and pushes it onto the view controller like so:

Search_Results_View *controller = [[Search_Results_View alloc] initWithNibName:@”Search Results NIB” bundle:[NSBundle mainBundle]];

controller.title = [NSString stringWithFormat:@"Poh's %@",[[tableData objectAtIndex:0] objectAtIndex:[indexPath indexAtPosition:1]]];

controller.filterBy.text = @”Hello World”;

appDelegate.vcRecipesScreen.vcResults = controller;

[controller release];

My issue is that the text on the label just won’t change! In fact, when I set break-points to see what is going on, filterBy is set to 0×0, which means it isn’t even being allocated…

So what is going on? Please help, I’m so confused…

In desperation I added another event: “Touch up inside”
It worked.

I experimented more. I think that
“Touch up outside” event is not generated at all!?

This may be bug in 3.1.2 simulator running under X10.6.2

Any ideas or similar experiences?
