ios - protocol method is not being called by the delegate -

i have implemented protocol in app,

i have declared protocol method in loginviewcontroller , calling protocolmethod confirmviewcontroller

here code snippet: loginviewcontroller.h

@protocol firstcontrollerdelegate<nsobject> @required -(void)protocolmethod;  @end  @interface loginviewcontroller : uiviewcontroller<firstcontrollerdelegate>  @end 

loginviewcontroller.m

- (ibaction)loginbtnclicked:(id)sender {     confirmviewcontroller *obj = [confirmviewcontroller new];      obj.delegate=self;    [self performseguewithidentifier:@"confirmloginsegue" sender:self];   }  -(void)protocolmethod{     nslog(@"--- not callled ---");      [self dismissviewcontrolleranimated:no completion:nil]; } 

code confirmviewcontroller.h

@interface confirmviewcontroller : uiviewcontroller  @property (nonatomic, assign) id <firstcontrollerdelegate> delegate;  @end 

confirmviewcontroller.m

 (ibaction)continueclicked:(id)sender {      [_delegate protocolmethod]; //calling protocol method...     [self dismissviewcontrolleranimated:yes completion:nil]; } 

where doing mistake?

please , in advance!

wrong approach , delegate initialisation

in lines:-

confirmviewcontroller *obj = [confirmviewcontroller new];      obj.delegate=self;    [self performseguewithidentifier:@"confirmloginsegue" sender:self];      --- loosing object here 

solution

in attribute inspector give identifier confirmviewcontroller, push vc , set delegate object confirmviewcontroller this:-

uistoryboard *storyboard = [uistoryboard storyboardwithname:@"mainstoryboard" bundle:nil]; confirmviewcontroller *confirmviewcontroller = [storyboard instantiateviewcontrollerwithidentifier:@"confirmviewcontroller"];  confirmviewcontroller.delegate=self;  [self.navigationcontroller pushviewcontroller:confirmviewcontroller animated:yes];
