Won't work when init with 0 numberOfMessages

[tobatha]

Hi Mohan,
Awesome MessageComposer.
Just one major issue, whenever the conversation initialized with NO messages, ie. [amDatasource numberOfMessages] returns 0 for the very first time, messages won't update even though messages's added later, and I spend a lot time on solving that issue with no luck. Could u help ? Thanks a lot

found the problem, you might wanna change your code to the following in *.m
first, in your original code you didn't check if numberOfRows > 0, which will cause crash if no messages, and i accidentally put "[self.messageTableView beginUpdates];" out side of the if condition, and keep the "[self.messageTableView endUpdates];" within the if condition, so it won't reload the data even though messages are added.

-(void) scrollToBottom:(BOOL)animated
{
NSInteger numberOfRows = [self.messageTableView numberOfRowsInSection:0];

if (numberOfRows > 0) {

    [self.messageTableView beginUpdates];
    NSIndexPath *lastCellIndexPath = [NSIndexPath indexPathForItem:numberOfRows - 1
                                                         inSection:0];
    [self.messageTableView scrollToRowAtIndexPath:lastCellIndexPath
                                 atScrollPosition:UITableViewScrollPositionBottom
                                         animated:animated];
    [self.messageTableView endUpdates];
}

}

Hi Tobatha, by adding rows to the tableView will not effect. It's still in development phase. When ever you want to update the tableview you can call "reloadMessagesData", which will reload the tableview.
