Error message when compiling while-loop expected identifier

Question

When trying to compile an infinite while loop in xcode iphone view based application, it gives me an error that reads expected identifier or '(' before 'while'. I made it as simple as possible. Sorry about the picture. Code block was not working. If you want to see an image of the code, here is the link. http://www.freeimagehosting.net/uploads/931d5d8788.gif

#import "Lockerz_NotifierViewController.h"

@implementation Lockerz_NotifierViewController
NSMutableData *responseData;

while (1) {
    NSURLRequest *theRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:@"http://amicionline.me"]
                                                cachePolicy:NSURLRequestUseProtocolCachePolicy
                                            timeoutInterval:60.0];
    // create a connection
    NSURLConnection *theConnection=[[NSURLConnection alloc] initWithRequest:theRequest delegate:self];

    if(theConnection) {
        // create the datum
        responseData=[[NSMutableData data] retain];
    } else {
        // code this later
    }
}

- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
    [responseData setLength:0];
}

- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
    // make it work
    NSLog(@"Succeeded! Received %d bytes of data:",[responseData length]);

    // release it
    [connection release];
    [responseData release];

}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data {
    [responseData appendData:data];
}

What are you trying to do? You can't write code directly in an @implementation. You must put it inside a method, for example:

-(void)start {
   while (1) {
     ...
   }
}
