我的应用程序遇到了这个问题,不知道出了什么问题。 致命异常:NSInternalInconsistencyException 缺少新显示的第78行的单元格
这是堆栈跟踪:

错误发生在这里:
- (void)insertNewComment:(NSIndexSet *)indexSet atLocation:(NSInteger)location{
[self.tableView beginUpdates];
NSMutableArray *indexArray = [NSMutableArray new];
if (!indexSet) {
[indexArray addObject:[NSIndexPath indexPathForRow:location inSection:0]];
} else {
[indexSet enumerateIndexesUsingBlock:^(NSUInteger index, BOOL *stop ) {
[indexArray addObject:[NSIndexPath indexPathForRow:index inSection:0]];
}];
}
[self.tableView insertRowsAtIndexPaths:indexArray withRowAnimation:UITableViewRowAnimationBottom];
[self.tableView endUpdates];
}
我使用AutoLayout作为单元格,但我手动计算高度并根据设备方向缓存它们。
身高计算器:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
Comment* comment = self.comments[indexPath.row];
CGFloat cellHeight = [self getHeightForLayoutMode:self.screenMode forCommentID:comment.commentID];
if(cellHeight > 0) {
return cellHeight;
}
if([comment isType2]) {
[self setHeightForLayoutMode:self.screenMode forCommentID:comment.commentID height:106];
return 106;
}
CGFloat width = tableView.bounds.size.width - 100;
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle defaultParagraphStyle] mutableCopy];
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
NSDictionary *attributes = @{NSFontAttributeName: [UIFont fontWithName:@"MyFont" size:11.0f], NSParagraphStyleAttributeName:paragraphStyle};
CGRect rect = [comment.message boundingRectWithSize:CGSizeMake(width, CGFLOAT_MAX)
options:NSStringDrawingUsesLineFragmentOrigin
attributes:attributes
context:nil];
CGFloat height = 31+ceilf(rect.size.height);
[self setHeightForLayoutMode:self.streamViewController.screenMode forCommentID:comment.commentID height:height];
return height;
}
有人有这样的问题(Crash with Missing cell for newly visible row when updating UITableView),他们刚刚删除了estimatedSectionHeaderHeight,但我的代码上没有estimatedSectionHeaderHeight。
答案 0 :(得分:0)
插入值时,如果节数超出范围,则会发生此错误。这不是身高问题。
答案 1 :(得分:0)
我找出了问题的原因。
在我的视图控制器中,我有一个textview,它将触发键盘显示。我将UITableView固定在底部。我在keyboardWillShow&上将它设置为scrollToBottom在textview高度更改时调整插入。一旦键盘显示,桌面视图几乎不可见(特别是在iPhone 5上)。
现在修复是我将tableview的底部固定在textview的顶部,保持相同的高度和高度。 tableview的可见性,我不需要scrollToBottom&再调整插入,因为自动布局会处理它。希望它可以帮助别人!
干杯。
