Question

我需要动态插入行动画＆amp;它在按钮水龙头上正常工作。但是当我在收到推送通知后在ViewDidLoad方法上实现它时，它就无法正常工作。

以下是代码：

[array_messages addObject:[messageInfo valueForKey:@"message"]];

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[array_messages count]-1 inSection:0];

messageFromTop=YES;

[self.tableViewMessage insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationTop];

Answer 1

请尝试这个。它可能对你有所帮助

dispatch_async(dispatch_get_main_queue(), ^{

     NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[array_messages count]-1 inSection:0];
    messageFromTop=YES;

    [self.tableView beginUpdates];
    [self.tableDatalist insertObject:obj atIndex:indexPath];

    [self.tableView insertRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:indexPath inSection:0]]
                          withRowAnimation:UITableViewRowAnimationRight];
    [self.tableView endUpdates];
});

Answer 2

使用此代码ViewDidLoad（）

   [self performSelector:@selector(insertRow) withObject:nil afterDelay:4];

然后

-(void)insertRow
{


dispatch_async(dispatch_get_main_queue(), ^{

     NSIndexPath *indexPath = [NSIndexPath indexPathForRow:[array_messages count]-1 inSection:0];
    messageFromTop=YES;

    [self.tableView beginUpdates];
    [self.tableDatalist insertObject:obj atIndex:indexPath];

    [self.tableView insertRowsAtIndexPaths:@[[NSIndexPath indexPathForRow:indexPath inSection:0]]
                          withRowAnimation:UITableViewRowAnimationRight];
    [self.tableView endUpdates];
});
}

tableview insertRowsAtIndexPaths无法在ViewdidLoad上运行
