Answer 1

IF what you're getting back really is a string, then you should look at the string searching methods like rangeOfString.
That will return an NSRange that contains your label, "place_addr".
Then you'd want to search from that point forward for a semicolon, using the related method rangeOfString:options:range:, that searches in a specific range of a string.
Finally, you'd need to calculate a range for the contents, that would be 5 characters past the end of the NSRange of "place_addr", and up to, but not including, the final semicolon.
Then you'd use substringWithRange to extract the string who's range you calculated above.
Give that a try, and come back if you have trouble.

Please try the code below
- (NSArray *)findKey:(NSString *)key inString:(NSString *)allString
{
NSMutableArray *result = [[NSMutableArray alloc] initWithCapacity:1];
NSArray *splitArray = [allString componentsSeparatedByString:#";"];
for (NSString *s in splitArray) {
NSArray * keyValueArry = [s componentsSeparatedByString:#"="];
if([keyValueArry count] > 1)
{
NSString *_key = [keyValueArry objectAtIndex:0];
NSString *_value = [keyValueArry objectAtIndex:1];
if([_key isEqualToString:key])
{
[result addObject:_value];
}
}
}
return result;
}
where key is place_addr, and allString is as your sample string.
