tableView加载完毕后回调的delegate方法: -(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { if([indexPath row] == ((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject]).row){ //end of loading //for example [activityIndicator stopAnimating]; } } ++++++++++++++++++++++++++++++++++++++ 由于willDisplayCell是异步调用的,所以在上面的block里面不能即时更新UI,最好使用GCD通过主线程加上你的代码: -(void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { if([indexPath row] == ((NSIndexPath*)[[tableView indexPathsForVisibleRows] lastObject]).row){ //end of loading dispatch_async(dispatch_get_main_queue,^{ //for example [activityIndicator stopAnimating]; }); } }标签:
