//[[[UIApplication sharedApplication] scheduledLocalNotifications] count];IF you are getting this proper after deleting the cell, then it won;t crash.Since you are deleting the cell but not updating the count so still it return 5 intend of 4 after deleting the data.
[self.tableView reloadData];
}
希望有效......让我们亲自动手

从崩溃日志中可以清楚地看到“第0节中的行数无效”是导致崩溃的原因。每次编辑单元格时，请调试应用程序以查看各部分的行。然后它将帮助您确定原因。
