iOS - UIImage着色突出显示始终为灰色

Question

我有这个按钮，背景颜色为白色，图像色调为颜色x。选择后，我希望颜色交换 - bg是x（我可以轻松做到），但图像色调总是灰色（或我设置的颜色的深色版本）。我怎样才能改变它？

UIImage *image = [UIImage imageNamed:@"House"];
        image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysTemplate];

        [self setImage:image forState:UIControlStateNormal];
        self.imageView.contentMode  = UIViewContentModeScaleAspectFit;

//

- (void)highlight {
    [super highlight];
    [UIView animateWithDuration:HIGHLIGHT_ANIMATION_TIME animations:^{
        self.tintColor = [UIColor whiteColor];
    }];
}

- (void)unhighlight {
    [super unhighlight];
    [UIView animateWithDuration:HIGHLIGHT_ANIMATION_TIME animations:^{
        self.tintColor = self.colour;
    }];
}

UIButton有许多州尝试：

//disable automatically adjust
self.yourButton.adjustsImageWhenHighlighted = NO;

[self setImage:colorChangedImage forState:UIControlStateHighlighted|UIControlStateSelected];
