I would like to write an enumerator that would go through a paragraph of text and gives me one sentence at a time. I tried using stringEnumerate with the NSStringEnumerationBySentences but that simply looks at the periods and fails. For example, lets say I have the following text Block:

"Senator John A. Boehner decided not to move forward. He also decided not to call the congress. The news reporter said though...."

I would like my function to break down the above paragraph in the following sentences:

1. Senator John A. Boehner decided not to move forward

2. He also decided not to call the congress (No third sentence because it's a half a sentence)

The String Enumerator with the sentence optionjust looks at the periods and breaks down that way which is wrong:

1. Senator John A.

2. Boehner decided not to move forward

3. He also decided not to call the congress

4. The news reporter said though....

Is there any library or function that I can call that does a better job at this?

Thanks

    [textBlock enumerateSubstringsInRange:NSMakeRange(0, [textBlock length])
                                  options:NSStringEnumerationBySentences | NSStringEnumerationLocalized
                                usingBlock:^(NSString *substring, NSRange substringRange, NSRange enclosingRange, BOOL *stop)
    {
        NSLog(@"Sentence Frag:%@", substring);                                                                        
    }];
    return textBlock;
