ios 11和iphone x的相关适配问题及解决方法

有关iOS11,最大的变化就是增加了一个安全区域（safeArea）的概念，iOS11适配的大部分问题都是由于它引起的。

在ios11中，tableView会莫名偏移，解决办法：

//解决iOS11tableview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(iOS11.0,*)){
if([scrollViewrespondsToSelector:@selector(setContentInsetAdjustmentBehavior:)]){
scrollView.contentInsetAdjustmentBehavior=UIScrollViewContentInsetAdjustmentNever;
}
}
#endif
}

关于iphonex适配，封装了一个类：代码如下：

ScreenTool.h

#import
#import
#defineViewSafeAreaInsets(view)[ScreenToolSharedInstancegetViewSafeAreaInsets:view]
#defineWindowSafeAreaInsets[ScreenToolSharedInstancegetWindowSafeAreaInsets]
#defineScreen_height[[UIScreenmainScreen]bounds].size.height
#defineScreen_width[[UIScreenmainScreen]bounds].size.width
#defineScreenToolSharedInstance[ScreenToolsharedInstance]
#defineNavAndStatusBarHeight[ScreenToolSharedInstancegetNavAndStatusBarHeight]
#defineTabBarAndVirtualHomeHeight[ScreenToolSharedInstancegetTabBarAndVirtualHomeHeight]
#defineStatusBarHeight[ScreenToolSharedInstancegetStatusBarHeight]
#defineNavContentHeight[ScreenToolSharedInstancegetNavContentHeight]
#defineTabBarContentHeight[ScreenToolSharedInstancegetTabBarContentHeight]
#defineScrollViewContentInsetAdjustmentBehavior(scrollView)[ScreenToolSharedInstancesetScrollViewContentInsetAdjustmentBehavior:scrollView]
