【iOS】AssistiveTouch熱鍵按鈕

AssistiveTouch熱鍵按鈕

介紹

  • 這是一個(gè)掛再界面上的控件，支持自由拖動(dòng) isPanMoview 通過這個(gè)屬性進(jìn)行設(shè)置
  • 這個(gè)按鈕就是類似于蘋果的AssistiveTouch熱鍵按鈕一樣 可以保留在界面之上

使用

  • 在使用的時(shí)候，要注意的是你把他加在在了哪一個(gè)視圖上，這會(huì)直接影響到使用的效果
  • 創(chuàng)建的時(shí)候，首先要注意的就是 setClickBlock 里面的事情 我們看到的效果 都是手動(dòng)設(shè)置的
  • 我們往里面添加 的時(shí)候 要注意調(diào)用 [- addViewToHotView:] 這個(gè)方法來添加
