小编kir*_*iri的帖子

在我的项目中,当我们选择项目时,我在下一个控制器中显示详细信息,但我已经使用Libxml获取详细信息,我必须在加载页面时禁用后退按钮,如何可能,请帮助我

谢谢

我在 returnData = [NSURLConnection sendSynchronousRequest:theRequest returningResponse:nil error:nil];

以下是我正在使用的代码

    NSString* curl = @"https://Some Url?ticket=";
curl = [curl stringByAppendingString:self.ticket];
curl = [curl stringByAppendingString:@"&apikey=hjgajgfjaghjf&XMLString="];
curl = [curl stringByAppendingString:stringB];
curl = [curl stringByReplacingOccurrencesOfString:@"\n" withString:@""];
NSURL *finalURL = [NSURL URLWithString:curl];

    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:finalURL cachePolicy:NSURLRequestReloadIgnoringCacheData   timeoutInterval:10]; 
     [theRequest setHTTPMethod:@"POST"];

   NSData* returnData= [NSURLConnection sendSynchronousRequest:theRequest returningResponse:nil error:nil];

任何一个可以告诉我为什么我在得到泄漏returndata我relased的returndata并尝试过,但我仍得到.

谢谢

我正在研究Rest Kit 0.2o,我正在使用一些来自Web的Json格式的示例URL,响应如下.我正在使用对象映射.我按照以下链接作为参考" https://github.com/RestKit/RestKit/wiki/Object-Mapping "我使用链接中给出的几乎相同的响应.

{
  "geonames": [
    {
      "fcodeName":"capital of a political entity",
      "toponymName":"Mexico City",
      "countrycode":"MX",
      "fcl":"P",
      "fclName":"city, village,...",
      "name":"Mexiko-Stadt",
      "wikipedia":"en.wikipedia.org/wiki/Mexico_City",
      "lng":-99.12766456604,
      "fcode":"PPLC",
      "geonameId":3530597,
      "lat":19.428472427036,
      "population":12294193
    },
    {
      "fcodeName":"capital of a political entity",
      "toponymName":"Manila",
      "countrycode":"PH",
      "fcl":"P",
      "fclName":"city,village,...",
      "name":"Manila",
      "wikipedia":"en.wikipedia.org/wiki/Manila",
      "lng":120.9822,
      "fcode":"PPLC",
      "geonameId":1701668,
      "lat":14.6042,
      "population":10444527
    }]
}

下面是代码

RKObjectMapping *newsMapping = [RKObjectMapping mappingForClass:[News class]];
[newsMapping addAttributeMappingsFromDictionary:@{
     @"fcodeName": @"fcodeName",
     @"toponymName": @"toponymName",
     @"countrycode": @"countrycode",
     @"fcl": @"fcl",
     @"fclName": @"fclName",
     @"name":@"name",
     @"wikipedia":@"wikipedia",
     @"lng":@"lng",
     @"fcode":@"fcode",
     @"geonameId":@"geonameId",
     @"lat":@"lat",
     @"population":@"population",
}];

RKResponseDescriptor* responseDescriptor = [RKResponseDescriptor responseDescriptorWithMapping:newsMapping
                                                                                   pathPattern:nil …

所有，

我有一个对象

public class Device {

     public String getUserId() {
        return userId;
    }
    public String getDeviceId() {
        return deviceId;
    }

}

我得到了所有的价值清单

     List<Device> uList = getList();

在列表中，我有一个基于userId的重复值现在我要获取“唯一”列表，该列表将删除userId的重复项
