<code objc>    
    -(NSComparisonResult)caseInsensitiveCompare:(NSString *)string;  
</code>

Returns the result of invoking compare:options: with NSCaseInsensitiveSearch as the only option.

===== ObjC Sourcecode Example =====
<code objc>  
    NSString *myString1=@"HELLO WORLD";
    NSString *myString2=@"hello world";
        
    if([myString1 caseInsensitiveCompare:myString2]==NSOrderedSame){
            
            NSLog(@"similar");  
        }
    else{
            
            NSLog(@"dissimilar");          
        }

      /* 
       defintion NSComparisonResult: 
       enum _NSComparisonResult {NSOrderedAscending = -1, NSOrderedSame, NSOrderedDescending};
       typedef NSInteger NSComparisonResult; 
       
       therefore, the comparative work with numerical values
       */
        
        if([myString1 caseInsensitiveCompare:myString2]==0){
            
            NSLog(@"similar");
        }
        else{
            
            NSLog(@"dissimilar");    
        }
