Formatting a String in Objective - C

I'm getting a response from webservice as a string like below one -

brand=company%%samsung@@modelnumber=webmodel%%GT1910@@Sim=Single%%SingleSim@@3g=yes%%Yes@@wifi=yes%%yes(2.1 mbps upto)

I'm confusing that to format my response like below one - 

brand=samsung
modelnumber=GT1910
Sim=SingleSim
3g=Yes
wifi=(2.1 mbps upto)

I've tried to remove the special characters (@@ and %%)

specialString = [specialString stringByReplacingOccurrencesOfString:@"@@" withString:@"\n"];
specialString = [specialString stringByReplacingOccurrencesOfString:@"%%" withString:@"\n"];
specialString= [specialString stringByReplacingOccurrencesOfString:@" " withString:@""];

My output was -

brand=company
samsung
modelnumber=webmodel
GT1910
Sim=Single
SingleSim
3g=yes
Yes
wifi=yes
(2.1 mbps upto)

How to remove unwanted words.

You can't use simple find and replace because there are parts of the original string you don't want.

Untested, but this will probably work:

NSArray *parts = [specialstring componentsSeparatedByString:@"@@"];
NSMutableArray *result = [[NSMutableArray alloc] init];
for(NSString *piece in parts) {
    NSArray *pairs = [piece componentsSeparatedByString:@"="];
    if([pairs count] > 1) {
        NSString *key = [pairs objectAtIndex:0];
        NSString *values = [pairs objectAtIndex:1];
        NSArray *avalues = [values componentsSeparatedByString:@"%%"];
        [result addObject:[NSString stringWithFormat:@"%@=%@", key, [avalues lastObject]]];
    }
}

NSLog(@"%@", [result componentsJoinedByString:@"\n"]);
// [result release]; // Uncomment if ARC is turned off

First splits by @@ and iterates over array. Then splits by = to get key on left side (index 0). Takes right side (index 1) and splits by %% and uses last value.

Trim like below it will work

NSString *strRes = @"brand=company%%samsung@@modelnumber=webmodel%%GT1910@@Sim=Single%%SingleSim@@3g=yes%%Yes@@wifi=yes%%yes(2.1 mbps upto)";
strRes = [strRes stringByReplacingOccurrencesOfString:@"=" withString:@"--"];
strRes = [strRes stringByReplacingOccurrencesOfString:@"@@" withString:@"\n"];
NSRange rangeForTrim;
while ((rangeForTrim = [strRes rangeOfString:@"--[^%%]+%%" options:NSRegularExpressionSearch]).location != NSNotFound)
    strRes = [strRes stringByReplacingCharactersInRange:rangeForTrim withString:@"="];

NSLog(@"%@",strRes);

Well, I can't write the code right away but here's what you gotta do:

  • Replace all %% with (space)
  • Replace all @@ with \n
  • Remove all words between = and (space)
