Button action event

Dear All!

In my very first iPhone App< i am trying to create one button(through code and not using IB) and then clicking that button, will read some file (file name is hard coded in the program) from local machine and will display the content on the iPhone.

I created button as:

- (void)loadView
{
UIView *contentView = [[UIView alloc] initWithFrame[UIScreen mainScreen] applicationFrame]];
self.view = contentView;

contentView.backgroundColor = [UIColor whiteColor];
contentView.multipleTouchEnabled= TRUE;
[contentView release];

// Add an action button
self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc]
initWithTitle"Browse"
style:UIBarButtonItemStylePlain
target:self
actionselector(presentSheet)] autorelease];

}


where "presentsheet" is a function that will include file opening and reading code.

Am I doing right? How to proceed in "presentsheet"?

Thnx in advance

First, use the CODE tag around code that you post. It will keep formatting as intended and not post messed up characters such at that sad face.

I haven't created a UIViewController manually before, but looking over your code and some documentation, your code looks fine to me.

I'm not sure what your really asking.

Perhaps you should read "Alerts, Action Sheets, and Modal Views" in Apple's iOS Human Interface Guidelines to see what fits for your scenario.

Your method name "presentsheet" suggests you want to display something from the file, but you haven't described what it is or how much screen space it may take. Perhaps placing it into a model UIViewController would make sense, or creating a custom presentation view. You are allowed to be creative.

Aside from the questions XStep presents -

You're adding a button to the navigation bar at the top with that code - is the nav bar even visible? Is this view controller that you are creating the custom view for even on a navigation controller stack?
