UILabel 自动改变颜色

Question

i'm facing a really strange problem: i have some UILabel in my view, which has a black background, so i set their text color to white in Interface Builder in order to see them, the problem is, when i run the app on the simulator or on my iphone with ios7 or iOS 6.1.3 i can update them without problems (for update i mean: myLabel.text = @"Something")

but when i run the app on my sister's iphone 3gs with iOS 6.0 at the moment i update them the font color turns black. It seems that on her phone the label can't remember the color set on IB.

Does anyone of you know why this happens? Thanks

Answer 1

It sounds like you have set the label "type" to "Attributed" in Interface Builder.

If this is the case then it is not the label that holds the text colour. It is the text itself.

If you replace the text with something else then the default text color of black will be used.

If you want to continue using Attributed text then you need to add a "foregroundColor" attribute to the text before setting it to the label.

The easier way round this is to change the label type to "Plain" in Interface Builder.

Of course, this depends on you having set it to Attributed.

我认为您不应在界面构建器中使用默认标签颜色，而应提供其他颜色（黑色等）。

I ran into a similar problem. Was stumping me completely, until I quit and relaunched the simulator. It wasn't enough to just close the window or rebuild. I had to cmd-q, then build and launch again. Magically fixed the issue. Annoying.. but worked for me
