Do like this.When you click on a button in button action call this.

UIActionSheet *photoActionSheet = [[UIActionSheet alloc] initWithTitle:@"" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@"Take Photo", @"Choose Existing",nil];

        [photoActionSheet showFromRect:CGRectMake(315, 355, 10, 10) inView:self.view animated:YES];

#pragma mark UIActionSheetDelegate methods

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{
    imgPicker.delegate = self;


    if(buttonIndex == 0){

            if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera]){
                imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
                [self presentModalViewController:imgPicker animated:YES];

        }


    else if(buttonIndex == 1){


            imgPicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            [self presentModalViewController:imgPicker animated:YES];


    }

}
