我想念什么？
// Excerpt from some .mm source file:
std::set locale(LC_ALL, "ru_RU.UTF-8");
int rv = strcasecmp([@"слово" UTF8String], [@"СЛОВО" UTF8String]);
assert(rv == 0);
我希望不区分大小写的比较能够成功完成，但是实际上我正在使用strcasecmp的非零返回码。
答案 0 :(得分：0)
var compositor = Window.Current.Compositor;
var easeIn = compositor.CreateCubicBezierEasingFunction(new Vector2(0.6f, 0.0f), new Vector2(0.9f, 0.0f));
var linear = compositor.CreateLinearEasingFunction();
var colorAnimation = compositor.CreateColorKeyFrameAnimation();
// 0.0f means at 0% of the total duration of 5s, 0.2f means 20%, etc.
colorAnimation.InsertKeyFrame(0.0f, Colors.Red, linear);
colorAnimation.InsertKeyFrame(0.2f, Colors.DarkOrange, easeIn);
colorAnimation.InsertKeyFrame(0.4f, Colors.Green, linear);
colorAnimation.InsertKeyFrame(0.6f, Colors.Purple, easeIn);
colorAnimation.InsertKeyFrame(0.8f, Colors.DarkSlateGray, linear);
colorAnimation.InsertKeyFrame(1.0f, Colors.Black, linear);
colorAnimation.Duration = TimeSpan.FromSeconds(5);
colorAnimation.IterationBehavior = AnimationIterationBehavior.Forever;
// Note the control exposes the inner DropShadow property, and this is the property we want to animate
ChristmasBonusStarUpperDropShadowPolygon.DropShadow.StartAnimation("Color", colorAnimation);
不起作用的原因是it's useless on multibyte strings。
由于您似乎正在使用strcasecmp()：
Objective-C++这应该适用于不区分大小写的匹配。
