非条形样式分段控件上的色调颜色

Question

I've got a compilation issue with a UiSegmentedControl, whose style is bezeled. The colour is black. I get an error:

"Tint color on non-bar style segmented control"

Can this be solved, and is it an issue for app submission?

Answer 1

I think that's a bug in Xcode/Interface Builder.
The iOS HIG say nothing about the different styles and the documentation explicitly allows tint colors for bezeled UISegmentedControls:

UISegmentedControlStyleBezeled
Segmented controls in this style can have a tint color.

I would just ignore the warning.

Answer 2

In the interface builder, select the Segment control.

In the Attribute inspector, Set the to .

Answer 3

For some reason, the XIB spouts this warning, but iOS indeed supports a tintColor with a bezeled style. You can avoid the warning by specifying it programmatically. There's a trick, though. If the style is set to bezeled, setting the tintColor will be ignored. You need to do it like this:

[segControl setSegmentedControlStyle:UISegmentedControlStyleBar];
segControl.tintColor = [UIColor colorWithWhite:0.48 alpha:1.0];
[segControl setSegmentedControlStyle:UISegmentedControlStyleBezeled];

In this case, I'm loading a XIB that has it set to bezeled (so I can see how it fits)...but I set it back to a bar and change the tint before setting it back. Weird.
