我对这段代码感到沮丧......
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:[NSBundle mainBundle]];
DoctorRecordController *object=[storyboard instantiateViewControllerWithIdentifier:@"DoctorRecord"];##############leaking code
object.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
[self presentViewController:object animated:YES completion:^(void){
}];
仪器在上述代码中显示泄漏。我怎样才能消除泄漏?
