问题描述

我正在更改组件(特别是组件的数量和颜色),在我称之为pickerOne的UIPickerView中,因此在进行更改后,我调用:

I'm changing components (in particular, the number and color of components), in a UIPickerView that I call pickerOne, so after making the changes, I call:

[pickerOne reloadData];

它似乎工作正常,但是我收到了编译警告:

and it appears to be working perfectly however, I'm getting a compile warning:

warning: 'UIPickerView' may not respond to '-reloadData'

虽然这似乎有用,但是我还应该用其他东西重新加载数据吗?

Although this appears to work, is there something else that I should use to reload data?

谢谢

推荐答案

我认为你应该使用:

reloadComponent:

reloadComponent:

reloadAllComponents:

reloadAllComponents:
