  <p>Incredibly, <strong>they do not include</strong> "standard Apple 'button blue'" ........</p>

  <p>In projects, we always have this: but it's a bit of a wild guess.</p>
  
  <pre><code>#define APPLEBLUE [UIColor \
    colorWithRed:0/255.0 green:122/255.0 blue:255/255.0 alpha:1.0]
  </code></pre>
  
  <p>Alternately, you can do something insanely complex like this.........</p>
  
  <pre><code>@implementation SomeButtons
  {
  UIColor *defaultColor;
  }
  
  -(id)initWithFrame:(CGRect)frame
      {
      defaultColor = [UIColor redColor];
      if(self = [super initWithFrame:frame])
          {
          for (UIView *v in self.subviews)
            if ([v isKindOfClass:[UIButton class]])
              defaultColor = [(UIButton *)v titleColorForState:UIControlStateNormal];
          }
      return self;
      }
  
  -(id)initWithCoder:(NSCoder *)aCoder
      {
      if(self = [super initWithCoder:aCoder])
          {
          for (UIView *v in self.subviews)
            if ([v isKindOfClass:[UIButton class]])
              defaultColor = [(UIButton *)v titleColorForState:UIControlStateNormal];
          }
      return self;
      }
  </code></pre>
  
  <p>It seems almost unbelievable there is not, an easier way, to return to "standard Apple control blue" for button and text colors.</p>
  
  <p>This is the sort of thing Android programmers laugh at us about :/  Does anyone know an easier way? I really hope I'm missing something obvious.   Cheers</p>
