从iPhone静态库中包含的类别的调用方法会导致NSInvalidArgumentException(Calling method on category included from iPhone static library causes NSInvalidArgumentException)

我创建了一个静态库来存放我的一些代码，如类别。

我在名为Extensions的“UIView-Extensions.h”中有一个UIView类别。

在这个类别中，我有一个方法叫做：

- (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration;

在调试配置模拟器上调用此方法可以很好地工作。

但是，如果尝试在设备上运行应用程序，则会收到NSInvalidArgumentException：

[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0

由于某种原因，UIView-Extensions.h似乎没有包含在设备构建中。

我已经检查/尝试过

我曾尝试为NSString添加另一个类别，并且遇到同样的问题。

其他文件，如整个类和函数工作正常。这是一个只发生在类别上的问题。

我做了一个干净的所有目标，但没有解决问题。

我检查了静态库项目，这些类别包含在目标的“复制标题”和“编译源”组中。

主要项目“链接二进制与库”组中包含静态库。

另一个项目中，我添加了静态库以便正常工作。

我删除并重新添加了没有运气的静态库

-ObjC链接器标志被设置

有任何想法吗？

I have created a static library to house some of my code like categories.

I have a category for UIViews in "UIView-Extensions.h" named Extensions.

In this category I have a method called:

- (void)fadeOutWithDelay:(CGFloat)delay duration:(CGFloat)duration;

Calling this method works fine on the simulator on Debug configuration.

However, if try to run the app on the device I get a NSInvalidArgumentException:

[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[UIView fadeOutWithDelay:duration:]: unrecognized selector sent to instance 0x1912b0

It seems for some reason UIView-Extensions.h is not being included in the device builds.

What I have checked/tried

I did try to include another category for NSString, and had the same issue.

Other files, like whole classes and functions work fine. It is an issue that only happens with categories.

I did a clean all targets, which did not fix the problem.

I checked the static library project, the categories are included in the target's "copy headers" and "compile sources" groups.

The static library is included in the main projects "link binary with library" group.

Another project I have added the static library to works just fine.

I deleted and re-added the static library with no luck

-ObjC linker flag is set

Any ideas?
