// example: [self colorizeStack:self.view];

- (void)colorizeStack:(UIView *)view {
    CGFloat hue = ( arc4random() % 256 / 256.0 );  // 0.0 to 1.0
    CGFloat saturation = ( arc4random() % 128 / 256.0 ) + 0.5;  // 0.5 to 1.0, away from white
    CGFloat brightness = ( arc4random() % 128 / 256.0 ) + 0.5;  // 0.5 to 1.0, away from black
    UIColor *color = [UIColor colorWithHue:hue saturation:saturation brightness:brightness alpha:0.8];

Now API looks like this:
- (void)getTapPoints;
- (void)spendTapPoints;
 
Here is how it would be absolutely awesome:
- (void)getTapPointsCompletion:(void (^)(TapjoyConnect *tj, NSUInteger tapPoints, NSError *error))completionBlock;
- (void)spendTapPoints:100 completion:(void (^)(TapjoyConnect *tj, NSError *error))completionBlock;
 
So, I could use it like this:
