How to develop an iOS framework which includes image resources?

Question

I am developing an iOS framework which includes image resources, I call the methods below in the framwork,

crossImage = [UIImage imageNamed:@"cross"];
arrowImage = [UIImage imageNamed:@"arrow"];

and then I build a demo to test my framework, but find crossImage and arrowImage are both nil; Afterwards, I figure out imageNamed:method will search images in the app's directory not in the framework's, so I can fix it by adding the two images to the demo project. However, it's barely elegant. so any other solutions to target the images in my framework?

Answer 1

You can load the image from framework using:

+ (UIImage *)imageNamed:(NSString *)name
               inBundle:(NSBundle *)bundle
compatibleWithTraitCollection:(UITraitCollection *)traitCollection

method.

In your framework class write like:

NSBundle *frameWorkBundle = [NSBundle bundleForClass:[self class]];
UIImage *arrow = [UIImage imageNamed:@"arrow" inBundle:frameWorkBundle compatibleWithTraitCollection:nil];
UIImage *cross = [UIImage imageNamed:@"cross" inBundle:frameWorkBundle compatibleWithTraitCollection:nil];

Refer UIImage Class Reference for more info about this method.

You can also load images using:

[[UIImage alloc] initWithContentsOfFile:path];

The path you'll want to generate from the bundle path. Something like:

NSBundle *bundle = [NSBundle bundleForClass:[YourFramework class]];
NSString* path = [bundle pathForResource:@"cross.jpg" ofType:nil];
