UIRefreshControl+Testing

Follow up on https://gist.github.com/koenpunt/cf8130bdfc432d31136b, but since method swizzling apparently doesn't work so well with Swift 3 anymore, I've now created it as Obj-C protocol.

When using in a Swift project, add it to the bridging header:

#import "UIRefreshControl+Testing.h"

Then you'll need to add a -DTESTING compile flag to the configuration you use for testing to enable this only for test builds.

UIRefreshControl+Testing.h

#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>

@interface UIRefreshControl(Testing)

@end

UIRefreshControl+Testing.m

#if TESTING
#import "UIRefreshControl+Testing.h"
#import <objc/runtime.h>

@implementation UIRefreshControl(Testing)

+ (void)load
{
    Method original, swizzled;
    
    original = class_getInstanceMethod(self, @selector(_setRefreshControlState:notify:));
    swizzled = class_getInstanceMethod(self, @selector(kp__setRefreshControlState:notify:));
    method_exchangeImplementations(original, swizzled);
}

- (void) kp__setRefreshControlState:(int)state notify: (BOOL)notify
{
    printf("kp__setRefreshControlState\n");
}

@end
#endif
