1.我们将网址进行转码

NSString *url = [strUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

2.更改请求的格式

AFHTTPRequestOperationManager *requestManager = [AFHTTPRequestOperationManager manager];

requestManager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/html", nil];

3.怎么判断一个字典的返回值为空，如果返回的responseObject[@"addressInfo"]为空的话，就不执行下面的代码。

NSDictionary*dic=responseObject[@"addressInfo"];

if (!([dic count]==0))

{

[[NSUserDefaults standardUserDefaults] setObject:responseObject[@"addressInfo"][@"address"] forKey:@"userInfo"];

[[NSUserDefaults standardUserDefaults] setObject:responseObject[@"addressInfo"][@"areaId1"] forKey:@"areaId1"];

[[NSUserDefaults standardUserDefaults] setObject:responseObject[@"addressInfo"][@"areaId2"] forKey:@"areaId2"];

[[NSUserDefaults standardUserDefaults] setObject:responseObject[@"addressInfo"][@"areaId3"] forKey:@"areaId3"];

}
