Trying to Display the load the image from the folder present on MAC desktop using path like (/Users/sai/Desktop/images/aaa.jpg) Which is created in plist file called Data.plist at item0.
As im using NSBundle it is diaplying the image path but not loading the image from the desktop .I have done a lots of research still couldn't find the solution .Plz help me .Here is the code
NSString *path=[[NSBundle mainBundle]pathForResource:#"Data" ofType:#"plist"];
NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:path];
NSString *errorDesc = nil;
NSPropertyListFormat format;
NSDictionary *temp = (NSDictionary *)[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&errorDesc];
NSArray *array=[NSArray arrayWithArray:[temp objectForKey:#"images"]];
NSString *object=[array objectAtIndex:0];
NSLog(#"object at index i %#",[object lastPathComponent]);
NSString *image=[object lastPathComponent];
mImageView.image=[UIImage imageNamed:image];
[self.view addSubview:mImageView];
Here is the screen shot of Data.plist
Simple and Short answer : It is not Possible to get image from MAC desktop, So please it better to stop fighting with it :)
It is different for mobile (iPhone application) and desktop (mac application), but why you want to do this ?? you know that your iOS application install in Apple iPhone ???? if your application is related to iOS ? then how you connect it to MAC OS ??
Best and simple way is put this image in Application Bundle or your Application's document directory and get it.

I am trying to use the SFTP library in NMSSH to download files from an ftp server and have been having trouble on my actual device. It works fine in the simulator. When I check for the file's existence in the stored directory (a created folder in my app's cache directory), the check passes on the simulator but fails on the phone. Below is the code I'm using. As a note, MainPath is the directory path and the fileListLevel1 row item is the file name with the extension.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *cacheDirectory = paths[0];
cacheDirectory = [#[cacheDirectory, #"/NewDirectory", #"/"] componentsJoinedByString:#""];
[[NSFileManager defaultManager] createDirectoryAtPath:cacheDirectory withIntermediateDirectories:false attributes:nil error: nil];
NSString *filePathToOpen = [#[MainPath, [fileListLevel1 objectAtIndex:indexPath.row]] componentsJoinedByString:#""];
bool isFile = NO;
bool isDir = NO;
isFile = [session.sftp fileExistsAtPath:filePathToOpen];
isDir = [session.sftp directoryExistsAtPath:filePathToOpen];
if (isFile){
NSString *fileToOpenNameAndPath = [#[cacheDirectory, [fileListLevel1 objectAtIndex:indexPath.row]] componentsJoinedByString:#""];
[session.sftp writeFileAtPath:filePathToOpen toFileAtPath:fileToOpenNameAndPath];
//FILE NOT FOUND ON THE PHONE - FOUND IN SIMULATOR!!!!!!!!
if ([[NSFileManager defaultManager] fileExistsAtPath:fileToOpenNameAndPath]){
NSLog(#"Found you!");
}
else if(![[NSFileManager defaultManager] fileExistsAtPath:fileToOpenNameAndPath]){
NSLog(#"Why you no there?");
}
I also tried creating the paths using the stringByAppendingPathComponent method and got the same result.
I'm new to app writing and objective c so I may be missing something fundamental here but I've been unable to find anything on this.
One additional question revolves around using the writeFileAtPath:toFileAtPath:progress command. I wonder if my issue is with the simulator writing much faster so my check happens before it is done on the phone. I'm not sure how to properly use the :progress portion as I'm unsure what type of variable the (BOOL (^)(NSUInteger sent)) is referring to or how to create one to check the progress.
Any help would be very much appreciated.
I've a magazine app that downloads PDF in /Library/Caches/... It works pretty well with iOS 7, but from iOS 8 ( that changes file system directories ) I can't open downloaded PDF! from PSPDFKit log error I see:
File downloaded path:
/Users/steven/Library/Developer/CoreSimulator/Devices/xxxxx/data/Containers/Data/Application/xxxxx/Library/Caches/doc1.pdf
PSPDFkit set document from path error:
Error: -[PSPDFGlobalLock documentProviderForDocument:page:]/248 Cannot get document reference, there is no file at /Users/steven/Library/Developer/CoreSimulator/Devices/xxxxx/data/Containers/Bundle/Application/xxxxx/[NAMEAPP]/Users/steven/Library/Developer/CoreSimulator/Devices/xxxxx/data/Containers/Data/Application/xxxx/Library/Caches/doc1.pdf!
Attention: I've replaced some words with xxxx
I'm using an old version of PSPDFKit( i don't known exactly version, I can't find version params )
i get "Caches" folder in this way ( called [Utility documents] in my code ):
NSArray *paths = [[NSArray alloc] initWithArray:NSSearchPathForDirectoriesInDomains( NSCachesDirectory, NSUserDomainMask, YES )];
return [paths objectAtIndex:0];
Download path PDF code:
NSString *destPath = [[Utility documents] stringByAppendingPathComponent:[[highlightedMagazine objectForKey:#"url"] lastPathComponent]];
Read PDF code for iOS 8:
NSString *destPath = [[Utility documents] stringByAppendingPathComponent:[[highlightedMagazine objectForKey:#"url"] lastPathComponent]];
pdfController.document = (PSPDFDocument *)[[Utility documents] stringByAppendingPathComponent:[[highlightedMagazine objectForKey:#"url"] lastPathComponent]];
I see also that download path is "/data/Containers/Data" and read path is "/data/Containers/Bundle", I can't change it.
Can someone help me?? Thank you!
I'm running Xcode 6 Beta 5 but this has been happening since the first beta. My app's directory in the simulator keeps being renamed after each run. It took me a while to figure this out. I'm using this to get the doc's dir reference.
NSString *folder = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask,
YES) lastObject];
NSLog(#"Documents Dir: %#",folder);
Now for example on the first run it'll be:
/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/4B10C2E4-A5C3-4C64-93B1-4069FCCB9C46/Documents
Second run now it's:
/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/7E9EB62D-115A-4092-AD23-CB6BA3E5E10F/Documents
Third run:
/Users/Joey/Library/Developer/CoreSimulator/Devices/5B9930EE-A9B4-4B36-BABB-AA864ACAF2DE/data/Containers/Data/Application/EC8F41E8-52ED-4B10-9808-B3ACC46FC6AA/Documents
This is wreaking havoc with my app because it stores path references for certain files within the app. It's not that my NSLog statement is returning incorrect results, I verified this is what happening in Finder. It's changing the name every time. Has anyone seen this happen? Is this a "feature" that I'm misunderstanding?
Turns out Xcode 6 does in fact change the app's UUID every run, and I'm in the wrong for storing absolute paths.
USE SIMPHOLDERS
I used this app on Xcode 5 opens the Documents folder, for the currently running app in the simulator, in Finder.
http://simpholders.com/
not ready for Xcode 6 yet (as of sep 24 2014) but saves all this hassle.
In Xcode 6 / iOS8 The bundle is now separate from the data./ The application GUID is regenerated between runs in Xcode (not sure why)
DOCUMENTS DIR:/Users/gbxc/Library/Developer/CoreSimulator/Devices/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Data/Application/C220D351-0BE7-46BA-B35E-D16646C61A3F/Documents
mainBundlePath_:/Users/gbxc/Library/Developer/CoreSimulator/Devices/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Bundle/Application/12200D1D-9B67-408B-BCF7-38206CBE0940/myappname.app/BLANK_BLOG_SCALED.jpg
1. FIND THE DEVICES FOLDER in SIMULATOR
/Users/gbxc/Library/Developer/CoreSimulator/Devices/
open each /device.plist to see which GUID is which device in XCode - I think this is static
3. FIND THE DEVICE you're running on iPad 2 - I think this is static
/Devices/AC79941F-EC56-495E-A077-773EEE882732
4. Find your application /Documents folder
/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Data/Application/C220D351-0BE7-46BA-B35E-D16646C61A3F/Documents
BEWARE the GUID C220D351-0BE7-46BA-B35E-D16646C61A3F is regenerated everytime the app is run in XCode 6
NSArray *paths_ = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
if(paths_){
_docsDir = [paths_ firstObject];
DebugLog(#"DOCUMENTS DIR:%#",_docsDir);
}else{
ErrorLog(#"paths_ is nil - cant get Documents directory");
}
MAIN BUNDLE path
NSString *mainBundlePath_ = [[NSBundle mainBundle] pathForResource:#"someimageinyourbundle" ofType:#"jpg"];
/AC79941F-EC56-495E-A077-773EEE882732/data/Containers/Bundle/Application/12200D1D-9B67-408B-BCF7-38206CBE0940/clarksonsiq.app/BLANK_BLOG_SCALED.jpg
NEVER CACHE THE PATH to /Documents between runs it will change.
I was serializing it to a plist and couldnt figure out why they kept disappearing
The GUID above /Documents keeps changing between runs but if you have /Documents open in Finder the folder stays open.

I can confirm that this is Xcode 6 related not iOS 8.
I have two development machines. On one of them I have Xcode 5. I was working all the time on that machine and my URL's were fine (photo app, photos are visible).
Yesterday I checked in form git my source on a machine with Xcode 6. I noticed that my photos are not visible any more, only photos that are created during that app session.
After little debugging, I realized that file:///var/mobile/Applications/B6A6BAEF-C90C-4A2A-93DB-E6700B88971F/Documents/ is changing on every app run.
All that time I am working with iOS 7 device.
I am going to check once more on a machine with Xcode 5 to confirm when I get my hands on it.
You need to to save only path inside DocumentDirectory(directory/file name), and add it to the DocumentDirectory every time you load the file...
-(void)saveImage:(UIImage *)image{
NSData *pngData = UIImagePNGRepresentation(image);
NSString *pathInDocumentDirectory = [APP_DocumentDirectory stringByAppendingPathComponent:PROFILE_IMAGE_NAME];
NSString *filePath = [self documentsPathForFileName:pathInDocumentDirectory];
//Save pic file path - DirName/Filename.png
[XYZPreferencesHelper setUserImageFilePath:pathInDocumentDirectory];
//Write the file
[[NSFileManager defaultManager] createFileAtPath:filePath contents:pngData attributes:nil];
}
-(void)loadSavedUserPicture{
//Load saved DirName/Filename.png
NSString *pathInDocumentDirectory = [XYZPreferencesHelper getUserImageFilePath];
if (pathInDocumentDirectory != nil){
//Full path with new app Document Directory
NSString *filePath = [self documentsPathForFileName:pathInDocumentDirectory];
if ([[NSFileManager defaultManager] fileExistsAtPath:filePath]){
NSData *pngData = [NSData dataWithContentsOfFile:filePath];
UIImage *image = [UIImage imageWithData:pngData];
if (image != nil){
userPicImageView.image = image;
}
}
}
}
- (NSString *)documentsPathForFileName:(NSString *)name
{
NSString *documentsPath = [self createRestcallDirectoryIfNotExist];
return [documentsPath stringByAppendingPathComponent:name];
}
-(NSString *)createRestcallDirectoryIfNotExist{
NSString *path;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsPath = [paths objectAtIndex:0];
path = [documentsPath stringByAppendingPathComponent:APP_DocumentDirectory];
NSError *error;
if (![[NSFileManager defaultManager] fileExistsAtPath:path]) //Does directory already exist?
{
if (![[NSFileManager defaultManager] createDirectoryAtPath:path
withIntermediateDirectories:NO
attributes:nil
error:&error])
{
NSLog(#"Create directory error: %#", error);
}
}
return documentsPath;
}
Because app's UUID changes and not reliable
so we should not store urls instead we should store just file names and reconstruct url at runtime , on update/reinstall iOS creates new home directory, stores app bundle in it and copies documents files so url changes
So, my app queries an Amazon Dynamo DB database and retrieves a few kilobytes worth of data. What I want the app to do is download everything the first time, and then every time after, just download a timestamp to see if it has the most recent version of the data. So that I only have to download the data every once in a while, I'm trying to use NSKeyedArchiver to archive the array that I'm downloading. I have tried this three different ways, and none of them work on an iPhone, although two of them work on the simulator.
[NSKeyedArchiver archiveRootObject:self.dataArray toFile:#"dataArray.archive"];
This does not work on the simulator nor the actual iphone. The result of this method is NO.
The next thing I used was the full path:
[NSKeyedArchiver archiveRootObject:self.dataArray toFile:#"Users/Corey/Desktop/.../dataArray.archive"];
And this worked on the simulator, but not on the iPhone. My guess was that when compiled, the filesystem looks different (and obviously doesn't have the same path). So next I tried:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"dataArray" ofType:#".archive"];
[NSKeyedArchiver archiveRootObject:self.dataArray toFile:filePath];
Once again, this works on the simulator but fails on the iphone. I have confirmed that all of the data is in self.dataArray before writing to the archive, and confirmed that the array is nil after writing back to the archive (in the iphone version). Any ideas what's going on? Is there a better way to do the filepath?
This is what I tracked down:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent: #"dataArray.archive"];
[NSKeyedArchiver archiveRootObject:your_object toFile:filePath];
and it worked perfectly on both the simulator and the iPhone!
[NSKeyedArchiver archiveRootObject:self.dataArray toFile:#"dataArray.archive"];
You have to provide a full path.
[NSKeyedArchiver archiveRootObject:self.dataArray toFile:#"Users/Corey/Desktop/.../dataArray.archive"];
That is not a full path. A full path begins with / and does not have /../ anywhere.
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"dataArray" ofType:#".archive"];
You do not have permission to write inside the mainBundle, it is read only.
Also, in general you shouldn't use file paths, you should use URLs. Some APIs (including this one) requires a path but URLs are the recommended approach these days.
Here's the proper way to write the file to disk:
NSURL *applicationSupportUrl = [[NSFileManager defaultManager] URLsForDirectory:NSApplicationSupportDirectory inDomains:NSUserDomainMask][0];
applicationSupportUrl = [applicationSupportUrl URLByAppendingPathComponent:#"My App"]; // replace with your app name
if (![applicationSupportUrl checkResourceIsReachableAndReturnError:NULL]) {
[[NSFileManager defaultManager] createDirectoryAtURL:applicationSupportUrl withIntermediateDirectories:YES attributes:#{} error:NULL];
}
NSURL *archiveUrl = [applicationSupportUrl URLByAppendingPathComponent:#"foo.archive"];
[NSKeyedArchiver archiveRootObject:self.dataArray toFile:archiveUrl.path];
I have a plist (NSDictionary) which I intended can be changed by user data input. Here is what I have done.
NSString *path = (the path for the plist)
NSMutableDictionary *plistFile = [[NSDictionary dictionaryWithContentOfFile:path] mutableCopy];
[plistFile setObject:(an NSString object) forKey:(an NSString key)];
[plistFile writeToFile:path atomically:YES];
So this is what I have coded. It works well on iPad 3 (new iPad) (iOS 6.1.2) and my XCode (4.6) simulator (iOS 6). However, it does not work on my iPad mini (iOS 6.1.3). I have found the problem which is in the last step. When I wrote
BOOL success = [plistFile writeToFile:path atomically:YES];
NSLog(#"%#",#(success));
The console always prints 0 which means it does not succeed. But on my iPad 3 and simulator it prints 1, which means success.
That is all I can describe because there is no exception being thrown out or other output. By the way, my iPad 3 (on which it works) is jailbroken but the iPad mini is not. Nevertheless, I use my developer account to codesign on both devices. Can anyone help me? Or else can anyone point to me a new solution?
Try to use
NSError * error = nil;
BOOL success = [plistFile writeToFile:path options:NSDataWritingAtomic error:&error];
NSLog(#"Success = %d, error = %#", success, error);
And then check what error occures. Maybe it can helps you.
And you can write only to the document directory. You may have some troubles with your path.
I can't see from your code if you have done this, but your path needs to be the sandboxed app directory.
NSArray* pathList = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
NSString* path = [[NSString alloc] initWithFormat:#"%#", [pathList objectAtIndex:0]];
