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 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 0x1912b0It 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?

唯一有效的解决方案是包括:
“-all_load”
在其他链接器标志。
编辑:一定要将此标志添加到项目包括静态库,而不是静态库本身。
我知道这不是正确的方法,但它现在正在工作。
这可能是OS 3.0的问题,因为这也是Three20的工作。
The only solution that worked was to include:
"-all_load"
in other linker flags.
EDIT: Be sure to add this flag to the project including the static library, not to the static library itself.
I know this isn't the correct method, but it is working for now.
It maybe a OS 3.0 issue since this was the work around for Three20 as well.
