How to download & display an image from ftp server - iphone

Question

(new to xCode and programming) I am trying to connect/download/save to variable and display an image in UIImageView from an ftp server. The code is below. Any help advice would be appreciated.
- (void)viewDidLoad
{
//sets label to notify user whats happening
NSMutableString *labelString;
labelString = [NSMutableString stringWithString: #"Connecting"];
[labelDymamic setText: labelString];
//variable for ftp location
NSString *ftpLocation = [NSString stringWithFormat:#"ftp2.bom.gov.au/anon/sample/gms/IDE00003.201011170430.gif"];
//variable to recieve data
NSMutableData *responseData;
//loads ftpLocation into url
NSURL *url = [NSURL URLWithString:ftpLocation];
//sets label to notify user whats happening
NSMutableString *labelStringDownloading;
labelStringDownloading = [NSMutableString stringWithString: #"Downloading"];
[labelDymamic setText: labelStringDownloading];
//Connect to ftp
self.ftpImageView.image = [UIImage imageNamed:#"Icon.png"];
self.labelDymamic.text = #"Receiving";
NSURLRequest *request = [NSURLRequest requestWithURL:url];
(void) [[NSURLConnection alloc] initWithRequest: request delegate:self];
//download image
//save to variable
//display to screen
//sets label to notify application loading complete
NSMutableString *labelLoadedString;
labelLoadedString = [NSMutableString stringWithString: #"Radar"];
[labelDymamic setText: labelLoadedString];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
At the moment all that is displayed is a white screen with labelLoadedString variable "Radar".
Thanks

Answer 1

your url is wrong, its missing the SCHEME: ftp://
as for downloading:
NSURLRequest *request = [NSURLRequest requestWithURL:url];
//download
[NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue] completionHandler:^(NSURLResponse * r, NSData * d, NSError * e) {
//save
UIImage *img = [[UIImage alloc] initWithData:d];
//display
self.imageView.image = img;
//sets label to notify application loading complete
NSMutableString *labelLoadedString;
labelLoadedString = [NSMutableString stringWithString: #"Radar"];
[labelDymamic setText: labelLoadedString];
}];

After fixing your URL, which as mentioned appears to be incorrect, checkout AFNetworking (see https://github.com/AFNetworking/AFNetworking). There's a category on UIImage that will make your life a lot easier when dealing with loading images from remote locations (such as over http, https, ftp, you name it ;)
Here's an example from their overview:
UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.0f, 100.0f)];
[imageView setImageWithURL:[NSURL URLWithString:#"http://i.imgur.com/r4uwx.jpg"] placeholderImage:[UIImage imageNamed:#"placeholder-avatar"]];
