ios 11和iphone x的相关适配

在ios 11中，tableView会莫名偏移，解决办法：

//解决iOS11 tableview会出现漂移,预估高度都设为0
        self.tableView.estimatedRowHeight = 0;
        self.tableView.estimatedSectionHeaderHeight = 0;
        self.tableView.estimatedSectionFooterHeight = 0;

解决scrollView，默认位移了，解决办法：

-(void)setScrollViewContentInsetAdjustmentBehavior:(UIScrollView *)scrollView {
    #if __IPHONE_OS_VERSION_MAX_ALLOWED >= 110000
        if(@available(iOS 11.0, *)) {
            if ([scrollView respondsToSelector:@selector(setContentInsetAdjustmentBehavior:)]) {
                scrollView.contentInsetAdjustmentBehavior = UIScrollViewContentInsetAdjustmentNever;
            }
        }
    #endif
    }

关于iphone x适配，封装了一个类：代码如下：

ScreenTool.h

#import <Foundation/Foundation.h>
    #import <UIKit/UIKit.h>
    
    #define ViewSafeAreaInsets(view) [ScreenToolSharedInstance getViewSafeAreaInsets:view]
    
    #define WindowSafeAreaInsets [ScreenToolSharedInstance getWindowSafeAreaInsets]
    
    #define Screen_height [[UIScreen mainScreen] bounds].size.height
    #define Screen_width [[UIScreen mainScreen] bounds].size.width
    
    #define ScreenToolSharedInstance [ScreenTool sharedInstance]
    
    #define NavAndStatusBarHeight [ScreenToolSharedInstance getNavAndStatusBarHeight]
    #define TabBarAndVirtualHomeHeight [ScreenToolSharedInstance getTabBarAndVirtualHomeHeight]
    
    #define StatusBarHeight [ScreenToolSharedInstance getStatusBarHeight]
    #define NavContentHeight [ScreenToolSharedInstance getNavContentHeight]
    #define TabBarContentHeight [ScreenToolSharedInstance getTabBarContentHeight]
    
    #define ScrollViewContentInsetAdjustmentBehavior(scrollView) [ScreenToolSharedInstance setScrollViewContentInsetAdjustmentBehavior:scrollView]
    
    typedef NS_ENUM(NSUInteger, DeviceScreenType) {//设备屏幕类型
        DeviceTypeIphone4Screen,
        DeviceTypeIphone5Screen,
        DeviceTypeIphone6Screen,
        DeviceTypeIphone6PlusScreen,
        DeviceTypeIphoneXScreen,
        DeviceTypeOtherScreen
    };
    
    typedef NS_ENUM(NSUInteger, DeviceOrientationType) {//屏幕方向类型
        DeviceOrientationTypeHorizontalScreen,
        DeviceOrientationTypeVerticalScreen,
        DeviceOrientationTypeOther
    };
    
    @interface ScreenTool : NSObject

    -(void)setScrollViewContentInsetAdjustmentBehavior:(UIScrollView *)scrollView;
    
    +(ScreenTool *)sharedInstance;

    -(UIEdgeInsets)getViewSafeAreaInsets:(UIView *)view;
