Can't create outlets in File's Owner on Xcode 4.5.1

Second, the brackets have the form [A B:1:2:3]

A is a 'class' which is a collection of a fundamental bit of programming with any number of attached 'methods' of additional programming. B is a method of A. 1,2 and 3 are arguments that B will use in its programming.

Altogether, everything in the brackets returns a value in place of the brackets when the application is running.

Third, an IBOutlet is a special type of variable that assigns the ability to be connected to a button.

If you want variable myVariable to be capable of holding an NSString, then you have to declare

NSString *myVariable

If you want myVariable to be capable of holding an integer, then you have to declare

int myVariable

etc. If you want myVariable to be connectable to a button in an .xib file, then you have to declare

IBOutlet myVariable

I may be wrong on some details, but this is the general idea.

NSURL *myURL = [NSURL URLWithString:@"htp//www.google.com"];

NSURL is a class.

myURL is an instance of that class.

This is very basic OOP. If you're having trouble with that, you're not going to get very far.

That looks more like what it should be to define myRequest. NSURL defines the type of variable, and *myRequest provides the name of the variable. The * means that the name of the variable has to be assigned a memory location for the actual value of the variable to be stored in. Everything after the = is what gets stored in the memory location. so since the the equals is in brackets, everything in the brackets will produce (or 'return') a value that is placed in the corresponding memory location for *myURL. Once myURL is then defined, you can refer to myURL without the *.

The brackets define (or 'return') a value by first calling on the 'class' (a group of related methods) and then naming the method with any of the necessary or optional arguments that the method will use to generate its result. The result then is 'returned' and put in place of the brackets at run time.

If you are learning from a video, you can't follow directions step-by-step unless the video was prepared with the exact same Xcode version you are using. That is one reason I prefer to follow the Apple documentation and example projects.

If your objective is to open a web page in a UIWebView, only four steps are required.

1. Create a new project using using the Single View Application template.

2. On the storyboard, drag a Web View onto the view controller.

3. Create the IBOutlet by Ctrl+dragging the web view into the header. Xcode will automatically add this property to the interface. No other code is necessary to implement the IBOutlet.

@property (weak, nonatomic) IBOutletUIWebView *webView;

4. Load the web page into the web view in the view controller's viewDidLoad.

- (void)viewDidLoad

{

[superviewDidLoad];

NSURL *url = [NSURLURLWithString:@"http://www.google.com"];

NSURLRequest *request = [NSURLRequest requestWithURL:url];

[self.webView loadRequest:request];

}
