I want to split the below string into sub string,
string = 000000000000000000111111111111111111111111000000. How to split like we have 48 characters in the mentioned string? I want to separate each character into an array so that I can fetch the values based on the index.

What about
unichar aCharacter = [string characterAtIndex: charIndex];

If you want to retrieve a certain character you can use [(NSString *)string characterAtIndex:(int)index];
e.g. get the char at index 0
unichar character = [string characterAtIndex:0];
If you want to split the string into substrings then you can use the split/substring functions – substringFromIndex:, – substringWithRange: and – substringToIndex:. There are lots more methods which you can use as well. Have a look at the NSString dev reference

By using toCharArray() method See this
String str="000000000000000000111111111111111111111111000000";
char[] cr=str.toCharArray();
System.out.println(cr[18]);//output:1

Using the blow code you can fetch the string with the index
NSMutableArray * stringArray = [[NSMutableArray alloc]init];
for (int i=0; i<yourString.length; i++) {
[stringArray addObject:[NSString stringWithFormat:@"%c",[yourString characterAtIndex:i]]];
}
NSLog(@"string %@",stringArray);
