Question

我有具有图像视图图像的customview，我正在将NSImageNameMenuOnStateTemplate设置为具有颜色的图像视图，但是没有应用颜色

NSImage *tintImage = [self tintedImage:[NSImage imageNamed:NSImageNameMenuOnStateTemplate] withTintColor:NSColor.whiteColor];

myimageView.image = tintImage

-(NSImage*)tintedImage:(NSImage*)image withTintColor:(NSColor*)color{
    NSImage *tinted = [image copy];
    [tinted lockFocus];
    [color set];

    NSRect imageRect = {NSZeroPoint, [image size]};
    NSRectFillUsingOperation(imageRect, NSCompositingOperationSourceAtop);
    [image unlockFocus];
    return tinted;
}

最感谢您的帮助。.

Answer 1

将[image unlockFocus];更改为[tinted unlockFocus];

对于macOS，您需要将setTemplate设置为NO

[tinted setTemplate:NO];

Answer 2

您确实应该避免使用lockFocus / unlockFocus。它们已过时，您已通过锁定一个图像并解锁另一个图像来滥用它们。使用`+ [NSImage imageWithSize：flipped：drawingHandler：]

作为NSImage的类别补充：

- (NSImage *)imageWithSolidFillColor:(NSColor *)color
{
    return [NSImage imageWithSize:self.size flipped:false drawingHandler:^BOOL(NSRect dstRect) {
        [self drawInRect:dstRect fromRect:NSZeroRect operation:NSCompositingOperationSourceOver fraction:1.0];
        [color set];
        NSRectFillUsingOperation(dstRect, NSCompositeSourceAtop);
        return YES;
    }];
}

NSMenuitem模板图像色调颜色不变
