标签： swift2 uipicker

我有一个快速项目，其中包含一个来自tableview的自定义单元格，在其中我有一个标签来显示UIPicker的值。当您按下标签时，UiPicker出现在键盘上，我无法将默认值设置为UIPicker，我尝试了两种不同的技术： // file2.html <!DOCTYPE html> <html> <head> <title>Fusion Charts Column 2D Sample</title> </head> <body> <div id="chart-container">FusionCharts will render here</div> <script src="js/jquery-2.1.4.js" type="text/javascript"></script> <script src="js/fusioncharts.js" type="text/javascript"></script> <script src="js/fusioncharts.charts.js" type="text/javascript"></script> <script src="js/themes/fusioncharts.theme.zune.js" type="text/javascript"></script> <script src="js/atr1.js" type="text/javascript"></script> </body> </html>，但没有成功，这是我的CustomCell代码：

selectRow()

更新了您的代码。
您没有设置 pickerView.dataSource ！
如果我理解你的问题，你希望默认选择一个元素，而不是索引0处的元素。 我还补充说。
