Thanks to Rufel's answer I was able to fix my issue and reduce the code of my class at the same time:

#import "AppButton.h"

@interface AppButton ()

@property (readonly) UIImage *normalImage;

@end

@implementation AppButton

@synthesize highlightTintColor = _highlightTintColor;

- (id)initWithCoder:(NSCoder *)aDecoder
{
    if (self = [super initWithCoder:aDecoder]) {
        [self initialize];
    }
    return self;
}

- (UIImage *)normalImage
{
    return [self imageForState:UIControlStateNormal];
}

- (void)initialize
{
    self.adjustsImageWhenHighlighted = NO;
    // set disabled image
    [self setImage:[self image:self.normalImage tintedWithColor:[UIColor colorWithRGBValue:RGBValueC9]] forState:UIControlStateDisabled];
}

- (void)setHighlightTintColor:(UIColor *)highlightTintColor
{
    _highlightTintColor = highlightTintColor;
    // update highlighted image
    if (highlightTintColor) {
        [self setImage:[self image:self.normalImage tintedWithColor:highlightTintColor] forState:UIControlStateHighlighted];
    }
}

- (UIImage *)image:(UIImage *)image tintedWithColor:(UIColor *)tintColor
{
    CGRect rect = CGRectMake(0, 0, image.size.width, image.size.height);
    UIGraphicsBeginImageContextWithOptions(image.size, NO, 0.0f);

    // Tint image
    [tintColor set];
    UIRectFill(rect);
    [image drawInRect:rect blendMode:kCGBlendModeDestinationIn alpha:1.0f];
    UIImage *tintedImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return tintedImage;
}

@end
