crash on deleteRowsAtIndexPaths

當我從表中刪除行時，我的應用程序崩潰。這裏是我的來源，其中發現錯誤和堆棧跟蹤。感謝名單！crash on deleteRowsAtIndexPaths

//delete row from database

我以前見過這個，肯定是你忘記了更新填滿表的數據源。但是那部分代碼缺失。造成這種情況的方法是

 

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
    return ; 
}

漂亮從錯誤信息明確：

「無效更新：在部分0包含在現有部分中的行數無效號碼的行在之後，更新（6）必須等於更新前（012），減去插入的行數或刪除該部分中的部分中包含的行數（0插入， 1刪除）。'

您嘗試刪除的對象不會在數據源中被刪除。
如果我假設您的UITableViewDataSource也使用dbManager，則必須修復dbManager以實際刪除該對象。

是的，問題是方法numberOfRowsInSection 所以，留下後患，你應該：

在功能上與陣列，數據庫等
遞減當前的行數commitEditingStyle刪除數據。
[tableView beginUpdates];
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject: indexPath] withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];

而且都是OK！

你需要包裹[開始和結束]內更新？ – alexzg 2014-05-06 02:09:44

我得到了同樣的錯誤，原因是我刪除最後一行中的表和爲0 我numberOfSectionsInTableView實現收益rowsArray計..

變爲最小值1破案

最新Swift解決方案

如果您要刪除節中的最後一行，您應該刪除整個節而不是行。要做到這一點：

tableView.beginUpdates() 
    self.dataArray.removeAtIndex(index.row) 
    if tableView.numberOfRowsInSection(index.section) == 1 { 
    tableView.deleteSections(NSIndexSet(index: index.section), withRowAnimation: .Automatic) 
    } 
    else { 
    tableView.deleteRowsAtIndexPaths([index], withRowAnimation: .Fade) 
    } 
    tableView.endUpdates()
