NSString *documentdir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *tileDirectory = [documentdir stringByAppendingPathComponent:#"xxxx/Tiles"];
NSLog(#"Tile Directory: %#", tileDirectory
Try this link. It will show you almost all the apps that you can open from your app using the URL Schemes and as the #trojanfoe has said, it is a duplicate.

I am using the following method to write image files out to the Applications/Documents folder:
- (void)saveImage:(UIImage *)image toFile:(NSString *)fileName
{
//get the data from the representation
NSData * binaryImageData = UIImagePNGRepresentation(image);
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
//write the data to a file
[binaryImageData writeToFile:[basePath stringByAppendingPathComponent:fileName] atomically:YES];
}
I thought I could just copy them to my computer, but that's not working out for me. Then, I decided to try to write the files to my hard drive. Nope. I guess that was a dumb idea, too.
I am processing bitmap images that I just want to capture somewhere (not on the device) where I can then retrieve them for testing. I've mucked with this for several hours and now it's getting late and I'm tired. Definitely ready for a little help.
Thank you in advance.
This question was answered by Rajesh Choudhary, but there were a few more hoops to go through to get the images off the phone and I wanted to post the entire process to help someone else in the future. So, here are the steps.
Enable file sharing from your app's info.plist file:
Use the code in the original post to write the file out to the
application /Documents folder.
Run your app to save the file to the iPhone application /Documents folder.
Check that your files were save by opening Organizer and selecting the iPhone running the application and selecting the application. The saved files will be located in the Documents folder in Data files in Sandbox.
To access them, open iTunes. Select the device running the application and select the Apps tab. Then, scroll to the File Sharing section, select the app and voila! The documents folder will display all your saved files on the device.
You can then select one or more of the files and click the Save to... button to save the files to your computer.
if you want to use images from device to your computer... you have to enable file sharing option in your app... When you enable it from your app's info.plist file you can see document folder in itunes.
Select you app from list and then, You can put & get files to/from document directory.
if you want to access image from document directory in app so you can use this method.
-(UIImage *)getImageFromDocumentDirectoryForFileName:(NSString *)fileName
{
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
UIImage *image =[UIImage imageWithContentsOfFile:[basePath stringByAppendingPathComponent:fileName]];
return image;
}
I've created an image file in an application and stored it in the fileDirectory using the following code:
NSArray * paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString * basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
UIImage* videoImage = [self resizeImage:[UIImage imageWithData:self.videoImageData] toWidth:width andHeight:height];
NSData *imageData2 = UIImageJPEGRepresentation(videoImage, imageQuality);
[imageData2 writeToFile:[basePath stringByAppendingPathComponent:#"myfile.png"] atomically:YES];
now from my iPhone device how can i find and open this file?
In Xcode you can go to Window->Organizer and select the Devices tab.
Under the device in the panel on the left you will see Applications. Select your application to see the file system for the app sandbox. Select Download to save all the data to the mac (as a package file).
You can right-click a package file to browse as a folder by selecting Show Package Contents from the context menu.
You would need to connect your iPhone to a Mac to see it. iExplorer does the trick.
imageData2 writeToFile:[basePath stringByAppendingPathComponent:#"/myfile.png"] atomically:YES];
you missed back slash
I got a question, which is, what if I can download a ebook file, eg .epub or PDF, then I list this file on a tableview, now I select one of the books.
Can I open via iBook?
Or I need to implement a reader to open the file?
Also got another question , I download a pdf file in my folder
The path I log it out , looks right
Here is the code:
NSString *docPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0];
NSString *ePubSubFolder = [docPath stringByAppendingPathComponent:#"Books"];
NSString *pdfPath = [ePubSubFolder stringByAppendingPathComponent:[NSString stringWithFormat:#"%#",self.pdfFileName]];
CFURLRef pdfURL = CFURLCreateWithFileSystemPath (NULL,(CFStringRef)pdfPath, kCFURLPOSIXPathStyle, FALSE);
NSLog(#"PDF URL: %#", pdfURL);
pdf = CGPDFDocumentCreateWithURL((CFURLRef)pdfURL);
CFRelease(pdfURL);
The log result is
../iPhone%20Simulator/4.3.2/Applications/06BA5929-3531-4AC3-B524-6CC74DC7E2C9/Documents/Books/Repeat%20After%20Me%20User's%20Guide.pdf
Do I did something wrong ?I won't show any thing on my view.
Many thanks for all reply or answer :-)
in IOS when you open a pdf using any application you get an option on the top right corner click on it and you can see options like open in ibooks etc.. I have tried this with many apps.
this is what I do to use some pdf on my ios devices.. load the file into a dropbox folder on the comp open it in the device in dropbox and then move it over to ibooks..
I am new to iPhone development. I have created plist such as from my previous post. It works well in simulator but not in device.
I am getting the saved value from the plist and checking for the condition. When I use simulator it works but not in device.
(1) You can't write to a file in the resource folder of an iPhone. It is part of the security system of the phone that prevent malicious code from altering an application after it has been installed.
(2) If you want to save new data to a file you need to write the file to one of the automatically generated folders. Whenever an iPhone app is installed on the device or simulator, the system creates a default set of folders.
(3) You want to write to either the Preferences folder or the Documents folder. If the data concerns the operation of the app, write it to preferences. If it contains user data write to Documents.
Preferences:
NSArray *sysPaths = NSSearchPathForDirectoriesInDomains(NSLibraryDirectory,NSUserDomainMask, YES);
NSString *prefsDirectory = [[sysPaths objectAtIndex:0] stringByAppendingPathComponent:#"/Preferences"];
Documents:
NSArray *sysPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory ,NSUserDomainMask, YES);
NSString *docsDirectory = [sysPaths objectAtIndex:0];
Say you want to read a default preference plist file, make some changes and then save it the preferences folder.
NSString *plistPath=[[NSBundle mainBundle] pathForResource:#"PlistFileName" ofType:#"plist"];
NSMutableArray *defaultPrefs=[[NSMutableArray alloc] initWithContentsOfFile:plistPath];
//... modify defaultPrefs
NSString *outputFilePath=[prefsDirectory stringByAppendingPathComponent:#"alteredPrefs.plist"];
[defaultPrefs writeToFile:outputFilePath atomically:NO];
i want to import some document in my app from iPhone something like PDF file or From another app ? is any way to do this ?
any link about that?
thanks
Here is a link about allowing the app to share its documents folder with itunes.

Alternatively you could use code in your app to write files into the apps "documents" directory directly. If neither of these two things are what you are looking for you can register your app to support a file format? But that doesn't sound like what you want.
- (NSString*)DocumentsPath
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, TRUE);
return [paths objectAtIndex:0];
}
//not every class supports writeToFile
- (void)writeToFile:(id)object withFileName:(NSString*)filename
{
[object writeToFile:[[self DocumentsPath] stringByAppendingPathComponent:filename] atomically:TRUE];
}
