無意中發現，有人創建UIButton這樣寫

UIButton *previousButton = [UIButtonbuttonWithType:101];

一看原來是私有api

UIButton *previousButton = [UIButton buttonWithType:101];[previousButton setTitle:@"<" forState:UIControlStateNormal];previousButton.frame = CGRectMake(0.f, 0.f, 30.f, 80.f);previousButton.center = CGPointMake(previousButton.frame.size.width / 2.f, pagingView.center.y);[previousButton addTarget:pagingView action:@selector(scrollToPreviousPage) forControlEvents:UIControlEventTouchUpInside];[self.view addSubview:previousButton];
