ios - Why do all the async image loading (SDWebImage, AFNetworking) libraries use UIImageView instead of UIImage? -


Am I missing something? It will not be allowed to be used with UIImage, is just more versatile than UIImageView? You can put hands around UIImage and use it for different things, where a UIImageView can actually be added only in the scene.

My initial idea was to keep it in another category and UIImage has been loaded so far, it will get zero and nothing new will be passed but if you If you pass UIImageView, will it apply?

FA networking

You are right, Implementation of Air Force Category (UIImageView + AFNetworking) is bare bones.

But you are missing out, which validate and decode images and provide some options to handle them. (In the old 1.x version of AFNetworking, this functionality is in.)

SDWebImage

Similarly, you are looking at only a very basic implementation of SDWebImage. There are so many options here, so I recommend that you review some other sections, but at the most basic level, you can get a UIImage like this: 

  SDWebImageManager * manager = [SDWebImageManager sharedManager]; [Manager downloadWithURL: imageURL Option: kNilOptions Progress: ^ (NSUInteger received size, NSUInteger is expected) {// Update See a progress} Complete: ^ (UIImage * image, NSError * error, SDImageCacheType cacheType, BOOL end) {If (image) {// Do something with the image; The cache type tells you whether it was cached or not. }}]; Loading of asynchronous  
 
 What if you put it in another category and UIImage has not loaded yet? 
 
 
 OK, all of this asynchronous is loaded, so the integer block will not be called until UIIm   is loaded.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
