How to extract a substring from a dynamic string in objective c?

Question

I have a string like @"Greetings from Capt. Ashim Mittra,​ Vice President – Flight Operations" from which I want to extract “Capt. Ashim Mittra”. i.e. I want to start from the word “from” and read to “,” (comma)

Answer 1

You can do something like,

   NSString *str = @"Greetings from Capt. Ashim Mittra,​ Vice President – Flight Operations";

NSRange range1 = [str rangeOfString:@"from"];
NSRange range2 = [str rangeOfString:@","];
NSRange rangeToSubString = NSMakeRange(range1.location + range1.length, range2.location - range1.location - range1.length);

NSString *resultStr = [str substringWithRange:rangeToSubString];

NSLog(@"path1 : %@",resultStr);

you can set attributed text to your label or else when you want to show your text with bold portion something like,

  UIFont *font = [UIFont boldSystemFontOfSize:17.0]; // whatever size, can use diiferent font with different method

NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:font,NSFontAttributeName, nil];

NSMutableAttributedString *resultStrWithBold = [[NSMutableAttributedString alloc]initWithString:str];

[resultStrWithBold setAttributes:dict range:rangeToSubString];

 yourLabel.attributedText = resultStrWithBold;
