ios - Buddy name in SMS? (Obj-C) -


i'm making app user can send sms prefilled phone numbers. loadstring, loadstring2, , loadstring3 strings uitextfields user can fill in , save. however, if user fills in 1 or 2 fields, , leaves 1 empty, recipients chosen phone numbers, , 1 contact called buddy name.

my question is, how rid of strange contact, called "buddy name"?

my code:

if ([mfmessagecomposeviewcontroller cansendtext])  {      [controller setrecipients:[nsarray arraywithobjects:loadstring, loadstring2, loadstring3, nil]];     [controller setbody:thelocation];     [self presentviewcontroller:controller animated:yes completion:null];  } else {             nslog(@"can't open text."); }

"buddy name" shows if array contains string isn't valid contact empty string. add strings recipients array if non-empty:

if ([mfmessagecomposeviewcontroller cansendtext]) {     nsmutablearray *recipents = [nsmutablearray array];     if ([self isvalidphonenumber:loadstring]) {          [recipents addobject:loadstring];     }     if ([self isvalidphonenumber:loadstring2]) {          [recipents addobject:loadstring2];     }     if ([self isvalidphonenumber:loadstring3]) {          [recipents addobject:loadstring3];     }     [controller setrecipients:recipents];     [controller setbody:thelocation];     [self presentviewcontroller:controller animated:yes completion:null];  } else {     nslog(@"can't open text."); }

...

- (bool)isvalidphonenumber:(nsstring *)phonenumberstring {     // if length 0 it's invalid. may want add other checks here make sure it's not invalid other reasons.     if (phonenumberstring.length == 0) {         return no;     } else {         return yes;     } }
