ios - 使用带有对象的协议(protocol)来获取对象的实例

Question

我是 Objective-C 的新手，正在尝试实现异议(依赖注入(inject)器)。

但它在下面不起作用是我正在使用的代码

My Protocol File 
#import <Foundation/Foundation.h>

@protocol InfoquestProtocolTest <NSObject>
-(void):nothing;
@end

My .h file is below
#import <Foundation/Foundation.h>
# import "InfoquestProtocolTest.h"


@interface InfoquestImplementation : NSObject<InfoquestProtocolTest>



@end

my .m file implementing protocol 


#import "InfoquestImplementation.h"

@implementation InfoquestImplementation
-(void):nothing{}
@end 

Code for module file of objection

#import "InfoquestTestConf.h"
#import <Objection/Objection.h>
#import "InfoquestViewController.h"
#import "InfoquestImplementation.h"
@implementation InfoquestTestConf
-(void)configure
{

    [self bindClass:[InfoquestImplementation class]   toProtocol:@protocol(InfoquestProtocolTest)];
}
@end

Code for getting object from objection

    JSObjectionInjector *injector = [JSObjection createInjector];
    [JSObjection setDefaultInjector:injector];
    InfoquestTestConf *Module = [[InfoquestTestConf alloc] init];
    [injector withModule: Module];
    id<InfoquestProtocolTest> testing2 = [injector getObject:[@protocol(InfoquestProtocolTest)];

但是当我尝试使用 [testing2 nothing] 进行调用时；我遇到错误，自动完成什么也没显示。

谢谢高拉夫

语法错误:

你应该替换:

-(void):nothing;

与

-(void)nothing;
