LLSlideViewController 分页控件 项目简介
LLSlideViewController 是一个新的分页控件，替代了 UIPageViewController，有效的避免了程序奔溃问题。使用示例：[self.slideViewController setViewController:[self viewControllerAtIndex:0]
direction:LLSlideViewControllerDirectionForward
animated:YES
completion:^{
NSLog(@"completed");
}];
direction:LLSlideViewControllerDirectionForward
animated:YES
completion:^{
NSLog(@"completed");
}];
