Loading images in background to optimize the loading in ios

Question

I am trying to optimize the load in my application, in fact, I have a lot of images that loaded in my application, and I spend a lot of time waiting for a view controller to ope

Answer 1

To enable the app while getting the images from server and disable block while loading the images try to use UIImageView+AFNetworking library to load the image from server asynchronously AFNetworking

   NSString *imageUrl = [[dict objectForKey:@"photo"] objectForKey:@"url"];

   UIImageView *myImage = [[UIImageView alloc] init];

   [myImage setImageWithURL:[NSURL URLWithString:imageUrl] placeholderImage:[UIImage    imageNamed:@"PlaceHolder.png"]];

Just add this library and include the UIImageView+AFNetworking so you can use the new UIImageView Category imageWithUrl
