需要用swift实现，将字符串数组合并为单个的字符串
最后直接＋即可：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | //merge character array into stringfunc mergeCharArrToSingleStr(charArr:[Character]) -> String { print("charArr=\(charArr)") //charArr=["一", "个", "字", "符", "串"] let mergedSingleStr:String = String(charArr) //"一个字符串" print("mergedSingleStr=\(mergedSingleStr)") return mergedSingleStr}//merge string array into single stringfunc mergeStrArrToSingleStr(strArr:[String]) -> String { print("strArr=\(strArr)") var singleStr:String = "" for eachStr in strArr { singleStr += eachStr } print("singleStr\(singleStr)") return singleStr} |
调用示例代码：
1 2 3 4 5 6 7 8 9 10 11 12 13 | /** mergeCharArrToSingleStr demo*/let charArrToMerge:[Character] = ["待", "合", "并", "字", "符", "数", "组"]let mergedStr:String = mergeCharArrToSingleStr(charArrToMerge)print("mergedStr=\(mergedStr)") //"待合并字符数组"/** mergeStrArrToSingleStr demo*/let stringArrToMerge:[String] = ["待", "合", "并", "字", "符", "串","数", "组"]let mergedSingleStr:String = mergeStrArrToSingleStr(stringArrToMerge)print("mergedSingleStr=\(mergedSingleStr)") //"待合并字符串数组" |
