来自iOS中服务器的图像库

Question

I'm working on retreiving images from server and display it in ios.I select the image that I need to see on full screen it comes. But the problem is, once I go back, it reloads the whole images again from server. Are there any solution so as to save it in cache file for a while. I searched the whole internet for this, but didn't get a proper solution. Can any one please specify best tutorial for that. I'm newbie to ios

Answer 1

If each time you go back it reloads all the images agin from the server is probably because you may either create a new view or because you are calling to load the images from the method viewWillAppear instead of in the viewDidLoad

- (void)viewDidLoad
{
    [super viewDidLoad];

    // Load the images here...

}

Instead of in here:

- (void)viewWillAppear:(BOOL)animated
{
   [super viewWillAppear:animated];
}

If this doesn't not help, please provide us with some code.
