Question

当我尝试按如下方式重新加载几行时，我的应用程序崩溃了：

[tblView reloadRowsAtIndexPaths:rowsToReload withRowAnimation:UITableViewRowAnimationNone];

但是，当我用以下代码替换行时，代码工作正常：

[tblView reloadData];

我得到的崩溃是

libc ++ abi.dylib：以NSException类型的未捕获异常终止

Answer 1

UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.3];

[CATransaction begin];
[CATransaction setAnimationDuration:0.3];

[CATransaction setAnimationTimingFunction:[CAMediaTimingFunction 
functionWithControlPoints:0 :1.8 :0 :1]];

[self.menuCollectionView performBatchUpdates:^{
  [tblView reloadRowsAtIndexPaths:rowsToReload withRowAnimation:UITableViewRowAnimationNone];
} completion:^(BOOL finished) {
}];

[CATransaction commit];
[UIView commitAnimations];

Answer 2

用作

 NSIndexPath* indexPath = [NSIndexPath indexPathForRow:2 inSection:0];

 NSArray* indexArray = [NSArray arrayWithObjects:indexPath, nil];

 [tblView  reloadRowsAtIndexPaths:indexArray withRowAnimation:UITableViewRowAnimationFade];

Answer 3

传递indexPath，如下所示。

{{ (post | async)?.id }}
{{ (post | async)?.title}}
{{ (post | async)?.content}}

reloadRowsAtIndexPaths崩溃; reloadData工作
