ios - 如何通过afnetworking与服务器通信？

我正在使用AFNetworking请查看我的代码

+(void)requestLogin:(id<LoginRequestDelegate>) delegate LoginURL:(NSString *)loginurl{

static User *user;
static id <LoginRequestDelegate> del;
del=delegate;
static AFHTTPRequestOperation *afRequest;
if(afRequest){
    return;
}
isLogin = NO;
Reachability *objInternetReachable = [Reachability reachabilityForInternetConnection];
NetworkStatus status = [objInternetReachable currentReachabilityStatus];
if(status != NotReachable) {
    NSString *strUrl=loginurl;
    NSLog(@"Login JSON URL %@", strUrl);
    strUrl=[strUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
    NSURLRequest *urlReq=[[NSURLRequest alloc] initWithURL:[NSURL URLWithString:strUrl] cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0];
    afRequest=[[AFHTTPRequestOperation alloc] initWithRequest:urlReq];
    AFNetworkActivityIndicatorManager * newactivity = [[AFNetworkActivityIndicatorManager alloc] init];
    newactivity.enabled = YES;
    [afRequest setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

        newactivity.enabled = NO;
        NSString *strRes=[[NSString alloc] initWithData:responseObject encoding:NSASCIIStringEncoding];
        //JSON DATA
        NSDictionary *dic=[[NSDictionary alloc]init];
        SBJsonParser *parser=[[SBJsonParser alloc] init];
        dic=[parser objectWithString:strRes];
        NSLog(@"Dic :- %@", dic);

        if(dic){
            NSString *isLoginRes = [dic objectForKey:@"login"];
            if([isLoginRes isEqualToString:@"true"]){
                NSLog(@"login res %@",isLoginRes);
                isLogin = YES;
                NSDictionary *resp = [dic objectForKey:@"resp"];
                user = [User sharedInstance];
                // User
                NSDictionary *userDic = [resp objectForKey:@"User"];
                user.userId = [userDic objectForKey:@"id"];
                user.userEmail = [userDic objectForKey:@"email"];

我正在使用这段代码，但是当我使用此方法时，它会跳到故障块。

[afRequest setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject)

该块不执行。

程序在该块上移动跳转

failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        newactivity.enabled = NO;
        if(del){
            [del isLoginRespomce:isLogin LoginDetail:user];
        }

最佳答案

您的代码可能更简单，将AFccinging用作AFHTTPRequestOperationManager，非常容易使用，并且与分配自己的AFHTTPRequestOperation一样好。

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
[manager GET:loginurl parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
    NSLog(@"JSON: %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
    NSLog(@"Error: %@", error);
}];
