How to download an image from a URL in Objective C iPhone?

This method downloads the image from the specified URL and stores in the documents directory and then shown in an ImageView.
Make sure you have an imageview linked with the outlet in the UserInterface.

-(void) downloadImageFromURL :(NSString *)imageUrl{
    
    NSURL  *url = [NSURL URLWithString:imageUrl];
    NSData *urlData = [NSData dataWithContentsOfURL:url];
    if ( urlData )
    {
        NSLog(@"Downloading started...");
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];
        NSString *filePath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"dwnld_image.png"];
        NSLog(@"FILE : %@",filePath);
        [urlData writeToFile:filePath atomically:YES];
        UIImage *image1=[UIImage imageWithContentsOfFile:filePath];
        imageView.image=image1;
        NSLog(@"Completed...");
    }
    
}
