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:
