iOS 6中的分段控件tintColor [英] Segmented control tintColor in iOS 6

问题描述

我有一个包含8段的分段控件。我可以更改整个控件的默认色调，但是我可以为控件中的每个段设置不同的颜色吗？我找到了一个在5.1中使用调用此方法的新类的教程，

I have a segmented control with 8 segments. I can change the default tint-color of the whole control, BUT can I set a different color for each segment in the control? I found a tutorial that worked in 5.1 with a new class that calls this method,

-(void)setTintColor:(UIColor*)color forTag:(NSInteger)aTag{}

但它在iOS 6中不起作用。想法？

But it doesn't work in iOS 6. Any ideas?

此问题已在此处修复。由于格式问题，我无法粘贴源代码。

这是一个hacky修复。这会奏效。将您的代码放在ViewDidAppear中。这就行了。

Its a hacky fix. This will work. Place your code in ViewDidAppear. That will do the trick.

- (void)viewDidAppear:(BOOL)animated 
{
    [super viewDidAppear: animated];
    dispatch_async(dispatch_get_main_queue(), ^{
        for (int i = 0 ; i < [segmentControl.subviews count] ; i++)
        {
            if ([[segmentControl.subviews objectAtIndex: i] isSelected] )
            {
                [[segmentControl.subviews objectAtIndex: i] setTintColor: [UIColor blackColor]];
                break;
            }
        }
    }); 
}
