我正在使用 Microsoft Azure 服务
进行项目开发。在删除一行时,遇到了以下错误:
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (2) must be equal to the number of rows
contained in that section before the update (2), plus or minus the number of rows inserted or deleted from that section (0 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).
加载和删除行的代码如下:- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 3;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
//medicine list
if (section == 0) {
NSArray *sectionInfo = [self.fetchedResultsController1 fetchedObjects];
return [sectionInfo count];
}
//allergy list
else if (section == 1) {
NSArray *sectionInfo = [self.fetchedResultsController2 fetchedObjects];
return [sectionInfo count];
}
//notes list
else if (section == 2){
NSArray *sectionInfo = [self.fetchedResultsController3 fetchedObjects];
return [sectionInfo count];
}
else
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"mcell";
MedicationTableViewCell *cell = (MedicationTableViewCell *) [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
// Add utility buttons
NSMutableArray *rightUtilityButtons = [NSMutableArray new];
[rightUtilityButtons sw_addUtilityButtonWithColor: [UIColor colorWithRed:1.0f green:0.231f blue:0.188 alpha:1.0f] title:@"Delete"];
switch (indexPath.section) {
case 0: {
NSManagedObject *item = [self.fetchedResultsController1 objectAtIndexPath:indexPath];
cell.textLabel.text = [item valueForKey:@"name"];
break;
}
case 1: {
NSManagedObject *item = [self.fetchedResultsController2 objectAtIndexPath:[NSIndexPath indexPathForRow:indexPath.row inSection:0]];
cell.textLabel.text = [item valueForKey:@"name"];
break;
}
case 2: {
NSManagedObject *item = [self.fetchedResultsController3 objectAtIndexPath: [NSIndexPath indexPathForRow:indexPath.row inSection:0]];
cell.textLabel.text = [item valueForKey:@"title"];
break;
}
default:
break;
}
cell.rightUtilityButtons = rightUtilityButtons;
cell.delegate = self;
return cell;
}
- (void)swipeableTableViewCell:(SWTableViewCell *)cell didTriggerRightUtilityButtonWithIndex:(NSInteger)index {
// Delete button is pressed
NSIndexPath *cellIndexPath = [self.medicationsTableView indexPathForCell:cell];
//fetchingg data from local store first
NSManagedObject *item = [self.fetchedResultsController1 objectAtIndexPath:[NSIndexPath indexPathForRow:cellIndexPath.row inSection:0]];
NSMutableArray *keys = [[NSMutableArray alloc] initWithObjects:@"id", @"name", @"userId", nil];
NSMutableArray *values = [[NSMutableArray alloc] initWithObjects: [item valueForKey:@"id"], [item valueForKey:@"name"], [item valueForKey:@"userId"], nil];
//creating dictionary of data
NSDictionary *dict = [[NSDictionary alloc] initWithObjects:values forKeys:keys];
//calling delete fucntion
[self.authService deleteItem:self.syncTable withDict:dict completion:^{
//removing row from table view
[self.medicationsTableView reloadData];
[self.medicationsTableView deleteRowsAtIndexPaths:@[cellIndexPath] withRowAnimation:UITableViewRowAnimationRight];
}];
break;
}
请告诉我我哪里出错了。先谢谢!!!
