Question

如何在First Name和Last Name中分割全名。

NSString *fullName = @"John Luke Morite";
NSString *firstName = [[fullName componentsSeparatedByString:@" "] objectAtIndex:0]; //John
NSString *lastName = ?? // Luke Morite

Answer 1

更好的方法：

NSString *fullName = @"John Luke Morite";
NSRange range = [fullName rangeOfString:@" "];
NSString *fname = [fullName substringToIndex:range.location];
NSString *lname = [fullName substringFromIndex:range.location+1];

Answer 2

NSString *fullName = @"John Luke Morite";
NSString *firstName = [[string componentsSeparatedByString:@" "] objectAtIndex:0]; //John
NSString *lastName = [fullName substringFromIndex:[fullName rangeOfString:firstName].length + 1];

Answer 3

这里的策略是寻找第一个空格，并采用剩余的字符

NSString *fullName = @"John Luke Morite";
NSRange range = [fullName rangeOfString:@" "];
NSString *lastName = [fullName substringFromIndex:range.length+1];

Answer 4

您也可以使用split来达到此目的：

   let text = "Stack Overflow Z"
   var fullNameArr = text.split(separator: " ", maxSplits: 1, omittingEmptySubsequences: true)
   let firstName: String = String(fullNameArr.first ?? "")
   let lastName: String =  fullNameArr.count > 0 ? String(fullNameArr[1]) : ""
