loading image fro MYSQL into Imageview - ios

Question

I have tried to find this answer for days now and cant find anything. I store url to image in my database and Im trying to get this url and load the image to a ImageView.
Users uploads a image and my PHP script makes a url to the image in the database. This is my database table: ID -> Username -> Password -> urlImage. And I have another PHP script that takes the username and askes for the urlImage.
In Xcode i want to add this: `
NSUserDefaults *settings = [NSUserDefaults standardUserDefaults];
NSString *user = [settings valueForKey:#"username"];
NSString *post = [NSString stringWithFormat:#"username=%#&image=dummy",user];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://url.com/Wish_Profile_Pic.php"]];
NSString *postLen = [[NSString alloc] initWithFormat:#"%d" ,[post length ]];
[request setValue:postLen forHTTPHeaderField:#"Content-Length"];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
//this is hard coded based on your suggested values, obviously you'd probably need to make this more dynamic based on your application's specific data to send
[request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
[[NSURLConnection alloc] initWithRequest:request delegate:self];
`
This will send a request to the database sever and the server will output the urlImage. How can I view the image in the ImageView? Cant find anything about this.

NSString *post = [NSString stringWithFormat:#"username=%#&image=dummy",use];
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:#"http://url.com/Wish_Profile_Pic.php"]];
NSString *postLen = [[NSString alloc] initWithFormat:#"%d" ,[post length ]];
[request setValue:postLen forHTTPHeaderField:#"Content-Length"];
[request setHTTPMethod:#"POST"];
[request setValue:#"application/x-www-form-urlencoded" forHTTPHeaderField:#"content-type"];
[request setHTTPBody:[post dataUsingEncoding:NSUTF8StringEncoding]];
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse *r, NSData *data, NSError *e) {
if(data.length) {
UIImage *img = [[[UIImage alloc] initWithData:data] autorelease];
//try base64
if(!img) {
//NEEDS http://projectswithlove.com/projects/NSData_Base64.zip
id b64 = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] autorelease];
id data2 = [NSData dataFromBase64String:b64];
img = [[[UIImage alloc] initWithData:data2] autorelease];
}
if(img)
self.imageView.image = img;
}
else if(e)
NSLog(#"%#", e);
}];
