   NSString *fourth=@"ImranAli";
   NSString *fifth=@"Ali Imran Jamshed";

I want to all these in single NSString to store and all values separated by given sign.

回答1:

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

回答2:

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

Short solution:

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

I guess what DrummerB suggested, is the best way. You have to store the strings in data structure. Array or dictionary for that matter.
If you just want to use strings it is not impossible, but it will be unwise. Here you go :

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"];

回答5:

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

The combined String looks like this @"Ali,Imran,AliImran,ImranAli,Ali Imran Jamshed";

To improve on Nitish's answer, you can reduce the number of lines by following this:

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