February 6th, 2009

I’m a big fan of simple, short tutorials that do what you need quickly. Here is a simple iPhone hello world tutorial with 3 steps and 3 lines of code. Download the source code

  1. Create a new iPhone project of the “View-Based Application” type. ( Helper Image )
  2. Open HelloWorldViewController.m in the “Classes” folder, uncomment the ViewDidLoad method on line #35 and add this code to it:( Helper Image )

     - (void)viewDidLoad {
    [super viewDidLoad];
	UILabel *helloLabel = [[UILabel alloc] initWithFrame:CGRectMake(100, 30, 100, 30)];
	[self.view addSubview:helloLabel];
	helloLabel.text = @"Hello World";
}
  3. Hit the “Build and Go” button and watch the magic.(or select Buld->Build and Go)

    Thanks! That’s exactly what a hello, world should be. Simplest program, so complete beginners can get started.

    Took me longer to google the tutorial than to get it working.

    Great!
