普通的alert
先看函数原型
alert: (title: string, message?: string, buttons?: AlertButton[], type?: string) => void
函数实现
Alert.alert(
'标题',
'内容',
[
{text: 'Ask me later', onPress: () => console.log('Ask me later pressed')},
{text: 'Cancel', onPress: () => console.log('Cancel Pressed'), style: 'destructive'},
{text: 'OK', onPress: () => console.log('OK Pressed')}
]
)
带输入框的alert-----iOS
原型
prompt: ( title: string, value?: string, callbackOrButtons?: (value: string) => void | Array<AlertIOSButton>, type?: string, defaultValue?: string ) => void
实现
AlertIOS.prompt(
'标题',
'内容',
(value:string)=>{
console.log(value);
},
'plain-text',
'default-string'
)
