Question

So I’m trying to access the variable ‘username’ from another class and append it to a URL as a string. I’m getting the error “No known class method for selector ‘myStaticUsername'” and don’t really know how to solve it. Any help would be appreciated.

FirstViewController.h

+(NSString *) username;

FirstViewController.m

static NSString *myStaticUsername = nil;

@implementation FirstViewController

+(NSString *) username{
    return myStaticUsername;
}
- (void)alertView:(UIAlertView *)alertView didDismissWithButtonIndex:(NSInteger)buttonIndex {
    if (buttonIndex == 0) {
        NSLog(@"Cancel Tapped.");
    }
    else if (buttonIndex == 1) {


        myStaticUsername= Textbox.text;
        NSLog(myStaticUsername);
}

My ViewController.m class where I’m trying to access it:

    - (void)viewDidLoad
{
    NSString *email = [FirstViewController myStaticUsername];

   NSString *website =[NSString stringWithFormat:@"http://www.nameofwebsite?un=:%@", email]; //append the username right here

Thanks.

In your viewDidLoad you need to change this:

NSString *email = [FirstViewController myStaticUsername];

to this:

NSString *email = [FirstViewController username];

myStaticUsername is the name of your static NSString, but the name of the class method you wrote to access it is username.
