Answer 1

Did you call the delegate function in UploadView? Also, since it is optional function, you have to check if the delegate response to the function before calling it.

- (void)yourFunction {
    ...
    if ([self.delegate respondsToSelector:@selector(takeAnotherPhoto:)]) {
        [delegate takeAnotherPhoto:self];
    }
    ...
}
