如何从混乱中调用原始方法? [英] How to call the original method from swizzled one?

问题描述

如何从混乱的状态中调用原始方法?

How to call the original method from swizzled one?

原始方法已替换为代码:

The original method is replaced by the code:

[[UIWindow class] jr_swizzleMethod:@selector(originalMethod) withMethod:@selector(swizzledMethod) error:nil];

swizzledMethod上的以下代码进行递归！

The following code on swizzledMethod makes recursion!

[self originalMethod];

如何解决这个问题?

我使用以下库进行缓存:

I use the following library for swizzling:

// JRSwizzle.h semver:1.0

#import <Foundation/Foundation.h>

@interface NSObject (JRSwizzle)

+ (BOOL)jr_swizzleMethod:(SEL)origSel_ withMethod:(SEL)altSel_ error:(NSError**)error_;
+ (BOOL)jr_swizzleClassMethod:(SEL)origSel_ withClassMethod:(SEL)altSel_ error:(NSError**)error_;

@end

推荐答案

答案非常有趣:

[self swizzledMethod]; // will call originalMethod
