ios - How to make recipients in MFMessageComposeViewController using a variable -

i'm trying use mfmessagecomposer pre-fill sms user. trying use variable stored in mutable array , use number pre-fill phone number. doesn't work code below @ recipient part. i've tried changing string, adding array. phone doesn't anything.

however if manual number using @[@"123132131235"]; recipients work.

- (ibaction)smssend:(id)sender {      {         mfmessagecomposeviewcontroller *controller = [[mfmessagecomposeviewcontroller alloc] init];         [controller setmessagecomposedelegate:self];         if([mfmessagecomposeviewcontroller cansendtext])         {              controller.recipients =  [[nsarray alloc] initwithobjects:[detail valueforkey:@"phone"], nil];              nslog(@"%@",[detail valueforkey:@"phone"]);              controller.body = @"hello testing";              [self presentviewcontroller:controller animated:yes completion:null];          }   else {             nslog(@"cannot send");         }     } } 

please me.

cheers, tony.

try this:

- (ibaction)smssend:(id)sender   {  {     mfmessagecomposeviewcontroller *controller = [[mfmessagecomposeviewcontroller alloc] init];     [controller setmessagecomposedelegate:self];     if([mfmessagecomposeviewcontroller cansendtext])     {         controller.recipients = [nsarray arraywithobjects:[detail valueforkey:@"phone"], nil];          controller.body = @"hello testing";          [self presentviewcontroller:controller animated:yes completion:null];     }        else      {         nslog(@"cannot send");     }  } }   

the change have made recipient array allocation. recipient array not array own instead of [nsarray alloc] should directly initialise array objects.

initwithobject returns array retain count of 1, i.e. own array , must release @ point prevent memory leaks.

arraywithobject returns autoreleased array not have worry releasing when don't need anymore (but if store in instance variable, should retain prevent autorelease pool freeing it)
