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

i have string @"greetings capt. ashim mittra,​ vice president – flight operations" want extract “capt. ashim mittra”. i.e. want start word “from” , read “,” (comma)

you can like,

   nsstring *str = @"greetings 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 label or else when want show text bold portion like,

  uifont *font = [uifont boldsystemfontofsize:17.0]; // whatever size, can use diiferent font different method  nsdictionary *dict = [nsdictionary dictionarywithobjectsandkeys:font,nsfontattributename, nil];  nsmutableattributedstring *resultstrwithbold = [[nsmutableattributedstring alloc]initwithstring:str];  [resultstrwithbold setattributes:dict range:rangetosubstring];   yourlabel.attributedtext = resultstrwithbold;
