新出版的iphone x被大家吐槽了，相信大家對iPhoneX的印象很深刻，今天就讓武林技術頻道小編為大家帶來ios 11和iphone x的相關適配問題及解決方法吧！
在ios 11中，tableView會莫名偏移，解決辦法：
//解決iOS11 tableview會出現漂移,預估高度都設為0 self.tableView.estimatedRowHeight = 0; self.tableView.estimatedSectionHeaderHeight = 0; self.tableView.estimatedSectionFooterHeight = 0;
解決scrollView，默認位移了，解決辦法：
-(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 } 關于iphone x適配，封裝了一個類：代碼如下：
