ShareKit方法在Lion/Xcode 4.3.1中泛滥成灾? [英] ShareKit method swizzling in Lion / Xcode 4.3.1?

问题描述

我最近使用iOS 5 SDK升级到Lion和Xcode 4.3.1，共享库 ShareKit 是损坏-它为电子邮件处理程序使用了混乱的方法.显然，Apple已被禁止，或至少试图逐步淘汰方法.

I recently upgraded to Lion and Xcode 4.3.1 with the iOS 5 SDK, and the sharing library ShareKit is broken - it used method swizzling for its email handler. Apparently Apple has banned or at least attempted to phase out method swizzling.

ShareKit导入不再存在的文件</usr/include/objc/objc-class.h>，并定义它自己的方法合并方法SHKSwizzle.它使用它来更改MFMailComposeViewController的viewDidDisappear:方法，如下所示:

ShareKit imports a file </usr/include/objc/objc-class.h>, which no longer exists, and defines its own method swizzling method SHKSwizzle. It uses this to alter MFMailComposeViewController's viewDidDisappear: method as follows:

SHKSwizzle([MFMailComposeViewController class], @selector(viewDidDisappear:), @selector(SHKviewDidDisappear:));

您认为解决此问题的最佳和最简便的方法是什么?

What do you think is the best and easiest way to work around this?

推荐答案

即使在最新的XCode和iOS SDK上，我也从未遇到过与方法相关的错误.我使用 ShareKit 2.0 .尽管我认为应该避免方法混乱.

I have never experienced method swizzling related errors on even on newest XCode and iOS SDK. I use ShareKit 2.0. Though method swizzling is a thing to be avoided in my opinion.

如果我记不清楚的话，陷入困境的方法是viewDidDisappear.看看它能做什么.在iOS 5上，您可以使用- (void)dismissViewControllerAnimated:(BOOL)flag completion:(void (^)(void))completion中的完成块来实现相同的目的.

The method swizzled is viewDidDisappear if I remember well. Look what it does. On iOS 5 you can achieve the same using completion block in - (void)dismissViewControllerAnimated:(BOOL)flag completion:(void (^)(void))completion.

只需更改在- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error中关闭viewController的方式就足够了.

Just change the way you dismiss the viewController in - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error might be enough.

这只是一个主意，如何摆脱方法的麻烦.

This is just an idea, how you might get rid of method swizzle.
