Question

I have the following code:

    //View guest list
-(IBAction) guestList:(id) sender{
    NSString *connected = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"myURL"]];

    //Waits a set peroid of time
    wait(20000);

    //Guest list is availible
    if (connected != NULL){
        CHARLIEAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
        [appDelegate displayView:6];
    }
    //No network connection availible
    else {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"No Network Connection!" message:@"Cannot establish internet connection."  delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        [alert release];
    }

 }

And I get the following warnings:

//Waits a set peroid of time
    wait(20000);

Gives me –
warning: passing argument 1 of ‘wait’ makes pointer from integer without a cast

NSString *connected = [NSString stringWithContentsOfURL:[NSURL URLWithString:@"http://photostiubhart.comoj.com/testconnection.php"]];

Gives me –

warning: ‘stringWithContentsOfURL:’ is deprecated (declared at /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks/Foundation.framework/Headers/NSString.h:384)

I’ve done my testing and the code SEEMS to work fine, even though there are these warnings. Is there a way to remove these warnings at all? Or do they not matter?

I’m using xCode version 3.2.6

Thanks,

Jack

use

NSError* error;  
NSString* connected = [NSString stringWithContentsOfURL:TheUrl encoding:NSASCIIStringEncoding error:&error];
