如何將Swift中的多參函數(shù)轉(zhuǎn)化成Curring函數(shù)

假定我們有1個(gè)含有多個(gè)參數(shù)的函數(shù)，用于構(gòu)建1個(gè)人的基本信息：
func buildInfoWithName(name: String,#age: Int,#gender: String,#address: String,#phone: String) -> String {
return "My name is " + name
+ ",I'm a " + gender
+ ",I live in " + address
+ ",my phone number is " + phone
}
let mike = buildInfoWithName("Mike",age: 20,gender: "boy",address: "Tokyo Japan",phone: "12345678")
如果我們不想1次性提供所有的參數(shù)，可以把它改造成Curring函數(shù)：
func buildInfoWithName(name: String)(age: Int)(gender: String)(address: String)(phone: String) -> String {
return "My name is " + name
+ ",I'm a " + gender
+ ",I live in " + address
+ ",my phone number is " + phone
}
let benson = buildInfoWithName("Benson")(age: 24)(gender: "boy")(address: "Chengdu Sichuan")(phone: "87654321")
我們把原始的函數(shù)已分解成了接受單1參數(shù)的函數(shù)序列。
