如何快速调用目标C中具有处理程序块的函数

Question

请任何人告诉我如何从swift调用目标c类中定义的“ attemptLogin”登录函数

#import <Foundation/Foundation.h>

@interface LoginHandler : NSObject<NSURLConnectionDelegate,NSXMLParserDelegate>{

}

typedef void (^CustomCallback)(NSDictionary *responseObj);

-(void)attemptLogin:(NSString *)userName andPassword:(NSString *)password completionHandler:(CustomCallback) callback;
@end

，即时通讯就像

var loginHandler = LoginHandler();
        loginHandler.attemptLogin(userMob, andPassword: userPass){
            data in


        }

但data以NSObject形式返回，但应为NSDictionary

假设您在目标C中有屏蔽-

 [[MyDataStore instance] askUserForMe:^(Person *person, NSError *error){
        // do things with myself that aren't strange
    }];

下面的代码将是您从swift调用时的代码-

MyDataStore.instance().askUserForMe() {
    person, error in 
    // do things with myself that aren't strange
}
