C# Xamarin仅在设备上丢失了自定义objc类别（无法识别的选择器发送到实例）
情况：C# Xamarin仅在设备上丢失了自定义objc类别（无法识别的选择器发送到实例）,c#,ios,xamarin,xamarin.ios,C#,Ios,Xamarin,Xamarin.ios,情况： 我在objc静态库中定义了一个自定义类别： @implementation UIViewController (Colorful) -(void)changeColor:(UIColor *)color { self.view.backgroundColor = color; } @end 它绑定到Xamarin项目： [Category, BaseType(typeof(UIViewController))] interface UIViewController_Colo
- 我在objc静态库中定义了一个自定义类别：
@implementation UIViewController (Colorful) -(void)changeColor:(UIColor *)color { self.view.backgroundColor = color; } @end - 它绑定到Xamarin项目：
[Category, BaseType(typeof(UIViewController))] interface UIViewController_Colorful { [Export ("changeColor:")] void ChangeColor(UIColor color); } - 此类别用于以下代码：
public override bool FinishedLaunching (UIApplication app, NSDictionary options) { window = new UIWindow (UIScreen.MainScreen.Bounds); UIViewController vc = new UIViewController (); vc.ChangeColor (UIColor.Red); window.RootViewController = vc; window.MakeKeyAndVisible (); return true; }
