Question

I ve been getting a table view inconsistency exception, wanting to know a way around it. Tapping on a table view cell accessory view, I display an additional cell in the table view, think of a control panel popping below the row you re looking at. Meanwhile, an HTTP request to an API is fetching the second page of data.. if the data comes in while I m animating the control panel, I get the crash.

NSInternalInconsistencyException , reason: Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (31) must be equal to the number of rows contained in that section before the update (32), plus or minus the number of rows inserted or deleted from that section (1 inserted, 1 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).

Solved! Turned out the issue wasn t in the content updates directly. I was adding a row in numberOfRowsInSection like so:

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {   
    NSInteger count = [self.sharedItems count];
    if (_contentPagesTotal > _contentPagesLoaded) {
        // Add a row for the loading label
        count++;
    }
    return count;
}

现在

if (self.showLoadingRow) {
    count ++
}

And in the content http callback: self.showLoadingRow = _contentPagesTotal > _contentPagesLoaded

因此,装货箱在装货时被 stick。
