    3 |
  1. When the button Clicked continuously，this category will be helpful。The button only response for the first event and then will ignore the remaining。We can customize the time interval
    2. 4 |
  2. When a button dones't hook this， wo need set the button Property ‘isIgnore' true
    3. 5 |
  3. Use UIButton+delay.The button only response for the last event and then will ignore the remaining。We can also customize the time interval
