假设我有两个数组：
@H_502_4@我想组合两个数组,以便我得到一个输出
- let letterArray = ["a","b","c","d","e"...]
- let numberArray = [1,2,3,4,5,6,7...]
@H_502_4@我该怎么做呢？
- ["a1","b2","c3","d4","e5"]
解决方法
您可以在地图前使用
zip(_:_:)：
@H_502_4@You can try this code here. @H_502_4@
- let a = ["a","e"]
- let b = [1,5]
- let result = zip(a,b).map{$0 + String($1)}
- print(result) // => ["a1","e5"]
zip(_:_:)生成一个自定义Zip2Sequence,它具有SequenceType协议的特殊实现,因此它迭代由两个源集合组成的对.
