Loading images from remote URLs

[daniel-hall]

Hi! Really like what you're doing with Classy, and I'm exploring its suitability for a large project I'm working on. One requirement this project has is the ability to load icons and images for styled elements from a URL, as opposed to only using resources in the app's bundle.

In Pixate / CSS, doing this works something like:

.myClass {
background-image: url("http://somewhere.com/images/icon.png");
}

Is there a similar functionality implemented or planned for Classy?

@daniel-hall while this is not directly supported at the moment. You can achieve the same thing in classy just with a bit more boiler plate

In the classy stylesheet

MyView.myClass {
    background-image-path: "http://somewhere.com/images/icon.png"
}

Then in your code, declare the property

@interface MyView
@property (nonatomic) NSString* backgroundImagePath;
@end

Then use something like UIKit+AFNetworking to load the image by overriding cas_updateStyling

@implementation MyView 
- (void)cas_updateStyling {
    [super cas_updateStyling]
    [self.imageView setImageWithURL:[NSURL URLWithString:self.backgroundImagePath]]
}
@end

@cloudkite Ah!! I get the idea. I'll play around with that -- thank you!
