iOS判断网络请求超时的方法
本文介绍了iOS判断网络请求超时的方法，代码具体如下：
+(AFHTTPRequestOperation*)requestOperationWithUrl:(NSString*)url
requetMethod:(NSString*)method
paramData:(NSDictionary*)aParamData
constructingBodyWithBlock:(void(^)(id<AFMultipartFormData>formData))block
success:(successBlock)success
failure:(failureBlock)failure{
AFHTTPRequestSerializer*requestSerializer=[AFJSONRequestSerializerserializer];
NSMutableURLRequest*request;
if(block){
method=@"POST";
request=[requestSerializermultipartFormRequestWithMethod:methodURLString:urlparameters:aParamDataconstructingBodyWithBlock:blockerror:nil];
}else{
request=[requestSerializerrequestWithMethod:methodURLString:urlparameters:aParamDataerror:nil];
}
AFHTTPRequestOperation*op=[[AFHTTPRequestOperationalloc]initWithRequest:request];
AFJSONResponseSerializer*responseSerializer=[AFJSONResponseSerializerserializer];
responseSerializer.removesKeysWithNullValues=YES;
responseSerializer.acceptableContentTypes=[NSSetsetWithObject:@"text/html"];
op.responseSerializer=responseSerializer;
__weakAFHTTPRequestOperation*weakOp=op;
[opsetCompletionBlockWithSuccess:^(AFHTTPRequestOperation*operation,idresponseObject){
if([responseObject[@"code"]integerValue]==0){
if(success){
//success(weakOp,aParamData,responseObject[@"list"]);
success(weakOp,aParamData,responseObject);
}
}else{
NSLog(@"operationerrormsg=[%@]",responseObject[@"description"]);
if(failure){
failure(weakOp,aParamData,[selferrorWithRet:responseObject]);
}
}
}failure:^(AFHTTPRequestOperation*operation,NSError*error){
NSLog(@"operationfailed=[%@]error=[%@]",operation,error);
if(failure){
failure(weakOp,aParamData,error);
}
}];
returnop;
}
打印error
ErrorDomain=NSURLErrorDomainCode=-1001"请求超时。"

NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=,_kCFStreamErrorCodeKey=-2102,NSErrorFailingURLKey=http://123.56.109.92/refitcar/service.s?sn=,NSLocalizedDescription=请求超时。,_kCFStreamErrorDomainKey=4,
NSUnderlyingError=0x167da8e0{

UserInfo={
_kCFStreamErrorCodeKey=-2102,
NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=,

NSLocalizedDescription=请求超时。,
_kCFStreamErrorDomainKey=4
}
}
}
可见：
poerror.localizedDescription 请求超时。
poerror.code -1001
poerror.userInfo
{
NSErrorFailingURLKey="http://123.56.109.92/refitcar/service.s?sn=";
NSErrorFailingURLStringKey="http://123.56.109.92/refitcar/service.s?sn=";
NSLocalizedDescription="\U8bf7\U6c42\U8d85\U65f6\U3002";
NSUnderlyingError="ErrorDomain=kCFErrorDomainCFNetworkCode=-1001\"\U8bf7\U6c42\U8d85\U65f6\U3002\"UserInfo={_kCFStreamErrorCodeKey=-2102,NSErrorFailingURLStringKey=http://123.56.109.92/refitcar/service.s?sn=,NSErrorFailingURLKey=http://123.56.109.92/refitcar/service.s?sn=,NSLocalizedDescription=\U8bf7\U6c42\U8d85\U65f6\U3002,_kCFStreamErrorDomainKey=4}";
"_kCFStreamErrorCodeKey"="-2102";
"_kCFStreamErrorDomainKey"=4;
}
所以使用error.code是否等于 -1001 判断请求超时
