1.註冊一個 註射器

@implementation Module

+ (void)load {
//默認註射器
    JSObjectionInjector *injector = [JSObjection defaultInjector];
//沒有就創建一個註射器
    injector 
 
= injector ? : [JSObjection createInjector];
    injector = [injector withModule:[[self alloc] init]];
    [JSObjection setDefaultInjector:injector];
}

- (void)configure {
    [self bindClass:[BViewController class] toProtocol:@protocol(BViewControllerProtocol)];
}

@end

- (IBAction)btnClick:(id)sender {

JSObjectionInjector *injector = [JSObjection defaultInjector];

UIViewController <BViewControllerProtocol> *vc = [injector getObject:@protocol(BViewControllerProtocol)];

vc.backgroundColor = [UIColor redColor];

vc.currentIndex = 1000;

[self.navigationController pushViewController:vc animated:YES];

}}
