有關iOS11 ,最大的變化就是增加了一個安全區域(safeArea)的概念,iOS11 適配的大部分問題都是由于它引起的。
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:
