objective-c - 如何在iphone中的一个字符串中添加连接多个NSString

Question

我有 5 个字符串，我希望它们必须存储在单个 NSString 中，所有值都用|符号分开

   NSString *first=@"Ali";
   NSString *second=@"Imran";
   NSString *third=@"AliImran";
   NSString *fourth=@"ImranAli";
   NSString *fifth=@"Ali Imran Jamshed";

我希望将所有这些存储在单个 NSString 中，并且所有值都由给定符号分隔。

Answer 1

NSArray *myStrings = [[NSArray alloc] initWithObjects:first, second, third, fourth, fifth, nil];
NSString *joinedString = [myStrings componentsJoinedByString:@"|"];
// release myStrings if not using ARC.

Answer 2

you can try ....
NSString *joinString=[NSString stringWithFormat:@"%@|%@|%@|%@|%@",youstring1,youstring2,youstring3,youstring4,youstring5];

Answer 3

简短的解决方案：

NSString *str = [@[nstring1, nstring2, nstring3] componentsJoinedByString:@","];

Answer 4

我猜 DrummerB 的建议是最好的方法。您必须将字符串存储在数据结构中。数组或字典。
如果您只想使用字符串，这并非不可能，但这是不明智的。干得好 ：

NSString*first=@"Ali";  
first = [first stringByAppendingString:@"|"];
first = [first stringByAppendingString:@"Imran"];
first = [first stringByAppendingString:@"|"];
first = [first stringByAppendingString:@"AliImran"];
first = [first stringByAppendingString:@"|"];
first = [first stringByAppendingString:@"ImranAli"];
first = [first stringByAppendingString:@"|"];
first = [first stringByAppendingString:@"Ali Imran Jamshed"];

Answer 5

NSArray *stringsArray = [[NSArray alloc] initWithObjects:first, second, third, fourth, fifth, nil];
NSString *combinedString = [stringsArray componentsJoinedByString:@","];

组合的字符串如下所示@"Ali,Imran,AliImran,ImranAli,Ali Imran Jamshed"；

Answer 6

为了改进 Nitish 的答案，您可以按照以下步骤减少行数：

NSString *first=@"Ali";  
first = [first stringByAppendingString:[@"|" stringByAppendingString:[@"Imran" stringByAppendingString:@"|"]]];
