Can anyone guide me how to filter the data. As it is a NSString. I am not able to convert it to dictionary. How to get the values for name, birthdate, birthplace, etc.

First Approach:-
First remove White spaces and irrelevant characters from the string.
Then, proceed in this way:-

NSArray *testArray = [yourString componentsSeparatedByString:@"|"];
NSString *key = [testArray objectAtIndex:0];
NSArray *values = [testArray subarrayWithRange:NSMakeRange(1, [testArray count] - 1)];
NSDictionary *dict = [NSDictionary dictionaryWithObject:values forKey:key];

And you can easily get the value of particular key like name, birthplace, etc.

Second approach:-

NSError *err = nil;
NSArray *arr = [NSJSONSerialization JSONObjectWithData:[yourString dataUsingEncoding:NSUTF8StringEncoding] options:NSJSONReadingMutableContainers error:&err];


NSMutableDictionary *dict = arr[0];
    for (NSMutableDictionary *dictionary in arr) {
        // do something using dictionary
    }
