小编use*_*321的帖子

] 2我正在使用AFNetworking将数据发送到server.Below是我的代码:

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager setRequestSerializer:[AFJSONRequestSerializer serializer]];
    [manager setResponseSerializer:[AFJSONResponseSerializer serializer]];
    [manager.requestSerializer setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];


    NSMutableDictionary *dict = [[NSMutableDictionary alloc]init];

    [dict setValue:[[arrLoginDetails objectAtIndex:0] objectForKey:@"id"] forKey:@"user_id"];

    [dict setValue:[[arrLoginDetails objectAtIndex:0] objectForKey:@"id"] forKey:@"shipper_id"];

    [dict setValue:strUuid forKey:@"imageOrderId"];

    [dict setValue:@"1" forKey:@"type"];

    NSData * imageData = UIImageJPEGRepresentation([aryImages objectAtIndex:0], 0.7);


   if([imageData length]>0){
    NSString *base64String = [imageData base64EncodedStringWithOptions:0];


    if([base64String length]>0){
    [dict setValue:base64String forKey:@"file_path"];

       NSString * reqFormat= [NSString stringWithFormat:@"%@&email=%@&dev_id=%@",UploadImage,[[arrLoginDetails objectAtIndex:0] objectForKey:@"email"],APP_DELEGATE.stringDeviceID];

 [manager POST:reqFormat parameters:dict1 success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
  }failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         NSLog(@"error:%@",error.debugDescription);

 }

以下是我得到的错误: …

如何在ios7中将圆角和边框应用于UISearchBar的背景？我可以改变条形图的背景颜色.

像这样的东西

谢谢

我有

NSstring *str = @"Existing applications can be improved or extended on 11-01-2014 at 4 PM for 120$ ";

从上面的字符串我想得到日期,时间和金额.上面的字符串我试图动态..

我试过的是

NSArray *arySeperator = [result componentsSeparatedByString:@" "];
for(int i=0;i< [arySeperator count];i++)
{

}

无法继续......

关于如何进一步的任何帮助或建议？

嗨，我想从“ 2017-07-31T11：40：00.000Z”获得11:40的时间

以下是我正在使用的代码：

     let formatter = Foundation.DateFormatter()
        formatter.dateFormat = "YYYY-MM-dd'T'HH:mm:ss.sssZ" //2017-04-01T18:05:00.000
        let date1  = formatter.date(from: data.arvTime)
        print("date:\(String(describing: date1))")
        let dateFormatterPrint = Foundation.DateFormatter()
        dateFormatterPrint.dateFormat = "HH:mm"
        let resultTime = dateFormatterPrint.string(from: date1!)
        print("time:\(String(describing: resultTime))")

将时间设为1：29，即我错了时间

请帮我解决这个问题。
