我想在dropdown列表中仅显示国家/地区名称，并希望将其ID传递给网络服务。如果用户选择印度，我必须通过3.我该怎么做？

Answer 1

据我所知，你有一个包含字符串的数组。

如果是这样，你只需要拆分你的字符串。

objective-c code

NSArray *country = @[@"3;India", @"4;US", @"5;UK"];
NSString *countryStr = country[0];      // 3; India
NSArray *countryArr = [countryStr  componentsSeparatedByString:@";"];
NSString *countryCode = countryArr.firstObject;  //3
NSString *countryName = countryArr.lastObject;   //India
NSLog(@"%@", countryCode);  //3
NSLog(@"%@", countryName);  //India

swift code

let country : NSArray = ["3;India", "4;US", "5;UK"]
let countryStr = country[0]
let countryArr : NSArray = countryStr.componentsSeparatedByString(";")
let countryCode = countryArr.firstObject
let countryName = countryArr.lastObject

if let countryCodePr = countryCode {
    print(countryCodePr)
}

if let countryNamePr = countryName {
    print(countryNamePr)
}

拆分数组对象＆＃34; 1; item1＆＃34;分为1和item1
