因为BlocksKit库导致融云选择拍摄照片失效问题

 - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    id realDelegate = self.realDelegate;
    if (realDelegate && [realDelegate   respondsToSelector:@selector(imagePickerController:didFinishPickingMediaWithInfo:)])
        [realDelegate imagePickerController:picker didFinishPickingMediaWithInfo:info];

    void (^block)(UIImagePickerController *, NSDictionary *) = [self blockImplementationForMethod:_cmd];
    if (block)   block(picker, info);
}

打印一下融云RCChatSessionInputBarControl所有实现的方法，可以发现他们实现的回调是一个过期的回调方法

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingImage:(UIImage *)image editingInfo:(nullable NSDictionary *)editingInfo NS_DEPRECATED_IOS(2_0, 3_0);

引以为鉴在设计第三方时也要考虑兼容DEPRECATED方法

打印类所有方法

  void DumpObjcMethods(Class clz)  {

    unsigned int methodCount = 0;
    Method *methods = class_copyMethodList(clz, &methodCount);
    
    printf("Found %d methods on '%s'\n", methodCount, class_getName(clz));
    
    for (unsigned int i = 0; i < methodCount; i++) {
        Method method = methods[i];
        
        printf("\t'%s' has method named '%s' of encoding '%s'\n",
               class_getName(clz),
               sel_getName(method_getName(method)),
               method_getTypeEncoding(method));
        
        /**
         *  Or do whatever you need here...
         */
    }    
    free(methods);
}
