I hope this helps you . To determine whether the app is run the first time, you need to have a persistent variable to store this info. NSUserDefaults is the best way to store these simple configuration values.
For example,
code :


Share : facebook icon twitter icon

wish of those help I placed a UITextField into a UIAlertView and moved it up so the keyboard wouldn't cover it up with the following code: , For those who may care, here's a working solution:
code :
UIAlertView* dialog = [[UIAlertView alloc] init];
[dialog setDelegate:self];
[dialog setTitle:@"Enter Name"];
[dialog setMessage:@" "];
[dialog addButtonWithTitle:@"Cancel"];
[dialog addButtonWithTitle:@"OK"];

nameField = [[UITextField alloc] initWithFrame:CGRectMake(20.0, 45.0, 245.0, 25.0)];
[nameField setBackgroundColor:[UIColor whiteColor]];
[dialog addSubview:nameField];
CGAffineTransform moveUp = CGAffineTransformMakeTranslation(0.0, 100.0);
[dialog setTransform: moveUp];
[dialog show];
[dialog release];
[nameField release];

I hope this helps . Your otherButtonTitles argument needs to be nil-terminated.
In general, methods that take a variable number of arguments, need to have nil at the end. For example:
code :
[NSArray arrayWithObjects:objA, objB, nil];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"error" message:@"message" delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:@"otherbutton", nil];

help you fix your problem I'm using this code: , If you combine everything into one line you can do so much easier.
code :
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Select Tutorial" message:@"" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Basic", @"Advanced", nil];

To fix this issue The easiest way to find this kind of bug is to use the NSZombieEnabled environment variable.
When you get an EXC_BAD_ACCESS at the end of a call, it usually means that something is being autoreleased, but it's retain count is already 0 from you releasing it.

it fixes the issue You're going to need the iPhone SDK up and running and you're going to want to go over the NSFileManager documentation.
