Answer 1

Use the NSString compare method (or one of the more detailed variations).

Answer 2

Steps:

1. Check if both the strings are of equal length.

   using ObjectiveC :

   ---

   [str1 length] == [str2 length];

2. If both the strings are of equal length, then compare character by character.

   using ObjectiveC:

   ---

BOOL isStringsEqual = YES; for(int i=0; i < [str1 length]; i++) { if([str1 characterAtIndex:i] != [str2 characterAtIndex:i]) { isStringsEqual = NO; break; } }

if(isStringsEqual) { NSlog(@"Both strings are equal"); } else { NSlog(@"Both strings are not equal"); }
