title: Custom UIButton hard to press
body: <p>If I add a basic UIButton all is well, they are always easy to press every time. However, when I make a custom version using my own .png it becomes hard to trigger every time.</p>
  
  <p>My custom button is a little smaller 32x32 and is mostly transparent. Could it simply be that its smaller, could the transparency be a problem..?</p>
  
  <p>many thanks for any thoughts..</p>
