Question

I need to create an app with tableView. For now I can just load/reload all data in my table. To add/delete operation tableView has editing mode. But the problem is that in this mode tableView shows standart add/delete buttons. But I don t need this buttons. In Apple tutorial I found other way to do add/delete row like this:

[data removeObjectAtIndex:0];
[data addObject:[[chooseTypeCell alloc]init]];
NSIndexPath *insertIndexPaths=[NSIndexPath indexPathForRow:[data count] inSection:0]; 
NSIndexPath *deleteIndexPaths=[NSIndexPath indexPathForRow:0 inSection:0];
[[self view] beginUpdates];
[[self view] insertRowsAtIndexPaths:[NSArray arrayWithObject:insertIndexPaths] withRowAnimation:UITableViewRowAnimationRight];
[[self view] deleteRowsAtIndexPaths:[NSArray arrayWithObject:deleteIndexPaths] withRowAnimation:UITableViewRowAnimationFade];
[[self view] endUpdates];

但造成错误=(......)。

因无一例外而终止职务:无有效表格观点更新。该申请要求更新表格中与数据来源所提供的数据不符的意见。

在我的案件中,使用物体的Im,该物体是UITableViewController的子产物,有UITableViewSource和UITableViewDelegate规程。就此而言,意见变量与我的可调意见有关。因此,UITableView与唯一的控制器连接。在这位控制员中,我界定了这些方法:

#pragma mark - Table view data source

Any ideas what s wrong?

Answer 1

否则:

Assertion failure in -[_UITableViewUpdateSupport _computeRowUpdates], /SourceCache/UIKit/UIKit-1912.3/UITableViewSupport.m:386 Terminating app due to uncaught exception NSInternalInconsistencyException , reason: Invalid table view update. The application has requested an update to the table view that is inconsistent with the state provided by the data source.

May appear because your UITable-Data class is wrong defined. You need to pay your attention to this methods:

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section

你们还需要检查你的算术。所有指数都必须从后数据结构上提取。

文件:

Deletion and reloading operations within an animation block specify which rows and sections in the original table should be removed or reloaded; insertions specify which rows and sections should be added to the resulting table. The index paths used to identify sections and rows follow this model. Inserting or removing an item in a mutable array, on the other hand, may affect the array index used for the successive insertion or removal operation; for example, if you insert an item at a certain index, the indexes of all subsequent items in the array are incremented.

在我的案件中:insertRowsAtIndexPaths功能出现错误。由于我的所有改动(我的数据)都在执行时适用。我的电文Cell的新立场是([数据]-1),而我只是使用[数据]。

感谢您的关注。
