UIScrollView适配

iOS 11废除了automaticallyAdjustsScrollViewInsets这个属性，转而使用了UIScrollView的contentInsetAdjustmentBehavior来替代。

1. AppDelegate中全局设置

    if (@available(iOS 11.0, *))
    {
        [[UIScrollView appearance] setContentInsetAdjustmentBehavior:UIScrollViewContentInsetAdjustmentNever];
    }

2. WKWebView 需要再单独设置（原因未知）

    if (@available(iOS 11.0, *))
    {
        self.webView.scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
    }

TableViewCell自适应

rowHeight与estimatedRowHeight缺一不可，同时要保证约束闭环，才能达到自适应的效果。Section Header与Section Footer同理。

1. 代码设置

self.tableView.rowHeight = UITableViewAutomaticDimension;
self.tableView.estimatedRowHeight = UITableViewAutomaticDimension;//不能兼容iOS9
self.tableView.estimatedRowHeight = 44;//兼容iOS9

2. Xib设置（均能兼容）

   
   

常见系统控件高度表

控件	竖屏	横屏
StatusBar	20	0
StatusBar(X)	44	0
NavigationBar	44	32
NavigationBar(XR、Max)	44	44
TabBar	49	32
TabBar(X)	83	53
TabBar(XR、Max)	83	70
HomeIndicator	34	21

#define IS_IPHONEX (IS_SCREEN_6_5_INCH || IS_SCREEN_5_8_INCH)

#define TabBarHeight(tabBar)                    CGRectGetHeight(tabBar.frame)
