Ios7 UIPickerView是否具有UITextView颜色？

我正在尝试将UITextView“文本颜色”更改为白色。我不在乎采摘者是否保持黑色，但如果能够同时改变两者，那就太好了。（文本视图显示UIPickerView选择的内容。）我正在使用故事板

我是新来的。这是我的

你真正的问题是什么<代码>[tvView setTextColor:yourColor]不起作用？请同时删除无用的代码（如iAd横幅、setTorch）。我认为一个

开关盒

会比其他的

更好，也更容易理解，如果

。你间接解决了它。[tvView setTextColor:yourColor]不，这不行。我找到了这个问题，不知道为什么我没有早点找到。[就像我说的我是新来的。iAd和setTourch有什么问题吗？你的iAd代码和setTorch与你的textview颜色问题无关。仅此而已。
