集成React Native中遇到的JSONKit错误

集成React Native完成之后，运行出现了如下错误：

根据上下文，可以看出React Native调用了项目中JSONKit的方法，搜索全项目之后，发现并没有导入JSONKit，猜测是项目中某个框架有导入，再看报错，说的是野指针错误，可能跟这个解析方法有关系，所以，在不修改源码的情况下我的解决办法是：

+ (void)replaceJSONKitStringSelector
{
    SEL jsonStringSelectorOld = NSSelectorFromString(@"JSONStringWithOptions:error:");
    if ([NSDictionary instancesRespondToSelector:jsonStringSelectorOld]) {
        SEL jsonStringSelectorNew = NSSelectorFromString(@"NEWJSONStringWithOptions:error:");
        
        Method jsonStringMethodNew = class_getInstanceMethod([NSArray class], jsonStringSelectorNew);
        
        class_replaceMethod([NSArray class],
                            jsonStringSelectorOld,
                            method_getImplementation(jsonStringMethodNew),
                            method_getTypeEncoding(jsonStringMethodNew));
    }
}

+ (void)replaceJSONKitObjectSelector
{
    SEL jsonObjectSelectorOld = NSSelectorFromString(@"JSONStringWithOptions:error:");
    SEL jsonObjectMutableSelectorOld = NSSelectorFromString(@"JSONStringWithOptions:error:");
    if ([NSString instancesRespondToSelector:jsonObjectSelectorOld]) {
        
        SEL jsonObjectSelectorNew = NSSelectorFromString(@"NEWJSONStringWithOptions:error:");
        SEL jsonObjectMutableSelectorNew = NSSelectorFromString(@"NEWJSONStringWithOptions:error:");
        
        Method jsonObjectMethodNew = class_getInstanceMethod([NSArray class], jsonObjectSelectorNew);
        Method jsonObjectMutableMethodNew = class_getInstanceMethod([NSArray class], jsonObjectMutableSelectorNew);
        
        class_replaceMethod([NSString class],
                            jsonObjectSelectorOld,
                            method_getImplementation(jsonObjectMethodNew),
                            method_getTypeEncoding(jsonObjectMethodNew));
        
        class_replaceMethod([NSMutableString class],
                            jsonObjectMutableSelectorOld,
                            method_getImplementation(jsonObjectMutableMethodNew),
                            method_getTypeEncoding(jsonObjectMutableMethodNew));
    }
}

+ (void)replaceJSONKitSelector
{
    [self replaceJSONKitStringSelector];
    [self replaceJSONKitObjectSelector];
}

- (NSString *)NEWJSONStringWithOptions:(NSUInteger)option error:(NSError **)error
{
    return [self modelToJSONString];
}

- (id)NEWObjectFromJSONStringWithParseOptions:(NSUInteger)parseOptionFlags error:(NSError **)error
{
    return [self modelToJSONString];
}

- (id)NEWMutableObjectFromJSONStringWithParseOptions:(NSUInteger)parseOptionFlags error:(NSError **)error
{
    return [self modelToJSONString];
}

@end

新增一个扩展类，在初始化RCTRootView之前调用一次[NSObject replaceJSONKitSelector]，问题就得到解决了。

大家在集成过程中是否有遇到同样的问题，或者有更好的解决方法，一起分享一下。。
