ios設置tableview默認選中第一行并實現(xiàn)點擊第一行的效果
//如果有數(shù)據(jù),默認選中第一行并請求第一行的數(shù)據(jù) if(self.tableViewData.count>0) { [self.tableView selectRowAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:0] animated:YES scrollPosition:UITableViewScrollPositionTop];//設置選中第一行(默認有藍色背景) [self tableView:self.tableView didSelectRowAtIndexPath:[NSIndexPath indexPathForItem:0 inSection:0]];//實現(xiàn)點擊第一行所調用的方法 }
