登录成功，拿到token

历尽波折，终于成功登录并拿到了token:

    - (LoginResultDto *)login:(NSString *)userName andPassword:(NSString *)password
{
    LoginRequestDto *requestDto=[LoginRequestDto new];
    requestDto.accountName = userName;
    requestDto.password = password;

    NSString *urlAsString = self.loginUrl;
    NSURL *url = [NSURL URLWithString:urlAsString];
    NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];
    [urlRequest setTimeoutInterval:30.0f];
    [urlRequest setHTTPMethod:@"POST"];
    [urlRequest setHTTPBody:[requestDto toJson]];

    NSURLResponse *response = nil;
    NSError *error = nil;

    NSData *responseData = [NSURLConnection sendSynchronousRequest:urlRequest
                                         returningResponse:&response

                                                             error:&error];

    if (!error) {
        LoginResultDto *result = [LoginResultDto deserialize:responseData];
        return result;
    }
    return  nil;
}

以下是本章基础时间

property getter setter 的实现

@property(nonatomic,strong,readonly) NSString *loginUrl;
- (NSString *) loginUrl
{
    return nil;
}

The compiler willautomatically synthesize an instance variable.If you implement both a getter and a getter for a readwrite property, or a getter for a readonly property, the compiler will assume that you are taking control over the property implementation and won't synthesize an instance variable automatically.

NSString 基础

NSString* str = [NSString stringWithFormat:@"%@",@"Hello World"]
