Question

我有这个按钮，背景颜色是白色，图像色调是颜色 x。选择后，我希望颜色交换 - bg 是 x（我可以轻松做到）但图像色调始终是灰色（或我设置的颜色的较暗版本）。我该如何更改它？

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 有很多状态尝试：

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

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

iOS - UIImage 着色高亮始终为灰色

iOS - UIImage tinting highlight always grey

tint

highlight
