我想设置一个UIAlertController带有四个动作按钮,按钮的标题设置为"心形","黑桃","钻石"和"俱乐部".按下按钮时,我想返回其标题.
总之,这是我的计划:
// TODO: Create a new alert controller
for i in ["hearts", "spades", "diamonds", "clubs"] {
// TODO: Add action button to alert controller
// TODO: Set title of button to i
}
// TODO: return currentTitle() of action button that was clicked
