ios 11和iphone x的相关适配问题及解决方法

2021-04-05 15:38杨克进 IOS

这篇文章主要介绍了ios 11和iphone x的相关适配,文中给大家提到了在ios 11中,tableView会莫名偏移问题的解决方法,非常不错,具有参考借鉴价值,需要的朋友可以参考下

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。

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:
