Question

In my viewDidLoad method, I set the following variables:

// Get requested URL and set to variable currentURL
NSString *currentURL = self.URL.absoluteString;
//NSString *currentURL = mainWebView.request.URL.absoluteString;
NSLog(@"Current url:%@", currentURL);

//Get PDF file name
NSArray *urlArray = [currentURL componentsSeparatedByString:@"/"];
NSString *fullDocumentName = [urlArray lastObject];
NSLog(@"Full doc name:%@", fullDocumentName);

//Get PDF file name without ".pdf"
NSArray *docName = [fullDocumentName componentsSeparatedByString:@"."];
NSString *pdfName = [docName objectAtIndex:0];

I would like to be able to use these variables inside of another method (i.e. - (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {)

How can I reuse these variables outside of the viewDidLoad method? I’m a newbie… help would be SO much appreciated

Answer 1

Make them an instance variable and not a variable local to the method you’re using. After that, you can access them from all methods of the same class.

Example:

@interface MyClass: NSObject {
    NSString *currentURL;
    // etc.
}

- (void)viewDidLoad
{
    currentURL = self.URL.absoluteString;
    // etc. same from other methods
}
