UIImageView+AFNetworking maxConcurrentOperationCount

This awesome UIImageView extension has the af_sharedImageRequestOperationQueue, where max concurrent number set as

_af_sharedImageRequestOperationQueue.maxConcurrentOperationCount = NSOperationQueueDefaultMaxConcurrentOperationCount;

How to access this private field and set custom value for maxConcurrentOperationCount? (I don't want to edit files under CocoaPods directly)

UPD: Thanks GeneratorOfOne, looks like the best solution for me. However, I decided to use SDWebImage, because it provides cache out of the box and allows to set maxConcurrentOperationCount in a line of code.

As explained in the definition NSOperationQueueDefaultMaxConcurrentOperationCount is meant to return the correct amount of concurrent queues allowed based on system conditions.

Why would you want to limit it?

This is a private method which has a static NSOperationQueue. You could either go and poke the code directly which is not good to change the existing code for some librarues. I would suggest you to create a new UIImageView category, where you would expose this method and then you could set the maxConcurrentOperationCount on it.

Like,

@interface UIImageView(MyExtension)
  + (NSOperationQueue *)af_sharedImageRequestOperationQueue;
@end

@implementation UIImageView(MyExtension)
  + (void)load {
     NSOperationQueue *queue = [self af_sharedImageRequestOperationQueue];
    queue.maxConcurrentOperationCount = 5;
  }
@end

Then, you could now include the extension in your class and set its maxConcurrentOperationCount.
