总结一下AFNetworking的基本使用方法。
①在AppDelegate.h中，导入AFHTTPRequestOperationManager.h文件，添加一个属性manager:
@property (strong,nonatomic(AFHTTPRequestOperationManager *)manager;
在实现文件中Application：didFinishLauchingWithOpertions:中完成manager的初始化：
self.manager ＝ [AFHTTPRequestOperationManager manager];
②在需要使用HTTP协议加载数据的地方，导入AppDelegate.h,实现以下语句：
appDelegate = [UIApplication sharedApplication].delegate;
NSString *str_input_data = [NSString stringWithFormat:@"238549_21963$2053$11$%@$%@$%@$%@$None$%@$O10.001$%@$%@$%@$%@$%@",ageCode,sexCode,nationCode,marryCode,symCode,self.highBPField.text,self.lowBPField.text,self.rateField.text,self.temperatureField.text,self.breathField.text]; NSString *temStr = [NSString stringWithFormat:@"http://url?str_input_data=%@",str_input_data];//str_input_data为服务端需要参数的接口 NSString *encoded = [temStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];//需要进行UTF-8编码转换才能是能被识别的URL [appDelegate.manager GET:encoded parameters:nil success:^(AFHTTPRequestOperation *operation, id resonseObject){
//这里面对接收到的responseObject进行处理,它已经是解析好的json文件了 resultKeys = [NSMutableArray array]; resultValues = [NSMutableArray array]; NSArray *array = resonseObject; for (NSInteger j = 0; j < array.count; j ++){ if (j % 2 == 0) { [resultKeys addObject:[array objectAtIndex:j]]; } else if (j % 2 == 1 && ![(NSString *)array[j] isEqual:@" 0"]){ //[resultValues addObject:[array objectAtIndex:j]]; [resultValues addObject:(NSString *)array[j]]; } else{ break; } } NSLog(@"keys=%@,value= %@",resultKeys,resultValues); [self.resultTable reloadData]; }failure:^(AFHTTPRequestOperation *operation, NSError *error){ NSLog(@"连接诊断结果服务错误：%@",error); }];
