title: Using a block object instead of a selector?
body: <p>I have:</p>
  
  <pre><code>[self schedule:@selector(tickhealth)];
  </code></pre>
  
  <p>And tickHealth method only has one line of code:</p>
  
  <pre><code>-(void)tickHealth
  {
      [hm decreaseBars:0.5];
  }
  </code></pre>
  
  <p>is it possible to use block objects in place of a selector. for example something like:</p>
  
  <pre><code>[self schedule:^{
      [hm decreaseBars:0.5];
  }];
  </code></pre>
