How to split a string using "-" keyword ?

This is My string i like to split it using special character "-"

hi - नमस्ते
Hindi - हिन्दी
Telugu - तेलुगु
how - कैसे
are - हैं
you - आप
go - जाना
going - जा रहा
translate - अनुवाद करना
good - अच्छा

What i was tried :

[strFileContent enumerateSubstringsInRange:NSMakeRange(0, strFileContent.length)
                                               options:NSStringEnumerationByWords
                                            usingBlock:
             ^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop) {
                 checking=substring;
                 NSLog(@"this is my splitting values =%@",substring);

             }];

If i did above method each word getting separately so that continues words getting brakes for eg translate - अनुवाद करना this word getting brakes .

2)[arrcheck addObject:[strFileContent componentsSeparatedByString:@"-"]];

if i did 2 method then n getting added
