Select File Name created with Date and Time for later use?

Question

 NSString *dateString= [self currentDateandTime];

//create file path and file name

  NSString *docDirectory =
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *pdfPath = [docDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"602_TW0023.%@_pdf.pdf",dateString]];
NSLog(@"Path: %@", pdfPath);

i converted an image to pdf and saved it with current date and time. How can i use this file to upload to ftp or php.

NSString* theFileName = [pdfPath lastPathComponent];

how to call above string into other method.can we set tag or what? i'm new to programming. point me right direction.

i tried a lot.

NSString *applicationDocumentsDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filepath =[NSString stringWithFormat: @"%@/%@",applicationDocumentsDir, @"%@"];

NSData *uploadData = [NSData dataWithContentsOfFile: filepath];

you can create a singleton or global variable, or you can get the names of all the files in the DocumentsDirectory and sort them by date.

thanks for reply. but i dont need to list. because those files are temporary files.my app handles only one file at a time — Avis, Aug 20 '14 at 16:28
is there any way to select file with it's extension? @IgnacyDebicki — Avis, Aug 20 '14 at 16:30
if you are handling one file at a time, you can always set a property of one of the classes as NSString that contains the filename — Ignacy Debicki, Aug 20 '14 at 16:30
i tried that, seriously but it didn't work for me.i set a property for file that i'm creating and i tried to retrieve..but i'm missing some logic @IgnacyDebicki — Avis, Aug 20 '14 at 16:34

also, if you are handling only one file at a time and then delete it, can't you use a static filename like "image.pdf"? — Ignacy Debicki, Aug 20 '14 at 16:55

in your class.h:

 @property(strong,nonatomic)NSString *filepath;

when you create the file path add:

self.filepath=pdfPath;

Then, when creating the data to upload use:

NSData *uploadData =[NSData dataWithContentsOfFile:self.filepath];

this will make sure you have the same file path when saving and reading the pdf
