React Native:iOS 警告

利用一个特定的标题和消息来启动一个警告对话框。

提供一个可选按钮的列表。点击任何按钮触发各自的按下回调动作,并且忽略警告。在默认情况下,只有一个按钮是“OK”按钮。列表中最后一个按钮被视为“主”按钮,它被用粗体显示出来了。

    AlertIOS.alert(      Foo Title,      My Alert Msg,
      [
        {text: Foo, onPress: () => console.log(Foo Pressed!)},
        {text: Bar, onPress: () => console.log(Bar Pressed!)},
      ]
    )}

方法

static alert(title: string, message?: string, buttons?: Array<{ text: ?string; onPress: ?Function; }>)
