I have this piece of code, which copies a plist file to the ApplicationSupport directory in the users folder.
NSString *resourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:kAutonumberPlist];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
NSString *dataPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:kAutonumberPlist];
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:dataPath]) {
[fileManager copyItemAtPath:resourcePath toPath:dataPath error:nil];
}
How ca I change it so that instead of copying the file into ~User/Library/ApplicationSupport, it will copy it into ~User/Library/ApplicationSupport/AnotherFolder. The "AnotherFolder" already exists by the way.
Thank you!
You are already using stringByAppendingPathComponent - you could just use it again.
For example:
NSString *dataPath = [[[paths objectAtIndex:0]
stringByAppendingPathComponent: #"AnotherFolder"]
stringByAppendingPathComponent: kAutonumberPlist];

I just want to replace static plist data to dynamic.this is my code
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *docDirPath = [documentsDirectory stringByAppendingPathComponent:#"sample.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath: docDirPath])
{
NSString *bundle = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"plist"];
[fileManager copyItemAtPath:bundle toPath:docDirPath error:&error];
NSLog(#"plist is copied to Directory");
}
i have some data in event array but its not writing/reading can you please suggest me where i am wrong.
NSLog(#"data coming from server....%#",self.eventDataArray);
//Writing array to document directory
NSArray *docpaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [docpaths objectAtIndex:0];
NSString *path = [NSString stringWithFormat:#"%#/sample.plist", documentsDirectoryPath];
[self.eventDataArray writeToFile:path atomically:YES];
NSLog(#"plist path string....%#",path);
//reading from document directory
NSMutableArray *readingArray=[[NSMutableArray alloc] initWithContentsOfFile:path];
NSLog(#"plist reading data is here......%#",readingArray);
I use the following code to copy a Resources plist file into the documents directory:
BOOL success;
NSError *error;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"Test-Info.plist"];
success = [fileManager fileExistsAtPath:filePath];
if (!success) {
NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingFormat:#"Test-Info.plist"];
success = [fileManager copyItemAtPath:path toPath:filePath error:&error];
NSLog(#"Test-Info.plist successfully copied to DocumentsDirectory.");
}
I get the success message, which is great. I'm assuming it's been copied correctly into the documents folder.
However when I then try to read and write to the saved plist file it returns null:
Key entry in Test-Info.plist:
Key: EnableEverything
Type: Boolean
Value: YES
Write code:
NSString *adKey = #"EnableEverything";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSString *path = [documentsDirectoryPath stringByAppendingPathComponent:#"Test-Info.plist"];
NSMutableDictionary *plist = [NSDictionary dictionaryWithContentsOfFile: path];
NSString *enableEverything = [[plist valueForKey:adKey] stringValue];
NSLog(#"****** EXISTING: %# ******", enableEverything); // returns (null)
// Disable in plist.
[plist setValue:0 forKey:adKey]; // will this work?
[plist writeToFile:path atomically:YES]; // this doesn't throw an error?
NSString *enableEverything1 = [[plist valueForKey:adKey] stringValue];
NSLog(#"****** NOW: %# ******", enableEverything1); // returns (null)
Output:
****** EXISTING: (null) ******
****** NOW: (null) ******
My question is why are they (null) when they exist within the plist file?
You are trying to mutate an immutable object.
You need a NSMutableDictionary.
IE
NSMutableDictionary *plist = [[NSDictionary dictionaryWithContentsOfFile: path] mutableCopy];
Also check, if the plist object isnt nil, as any messages can be send to nil without raiing an error. this wouldnt fail, also nothing actually happens.
[plist setValue:0 forKey:adKey]; // will this work?
[plist writeToFile:path atomically:YES]; // this doesn't throw an error?
as the source path is nil, you are most like not copying the file during compilation bundling. drag it here:
Try this for nsbundle path for resource
NSString *path= [[NSBundle mainBundle] pathForResource:#"SportsLogo-Info" ofType:#"plist"];
Try allocating
NSMutableDictionary *plist = [[NSMutableDictionary alloc] initWithDictionary:[NSDictionary dictionaryWithContentsOfFile:path]];
Also check if the file has been copied or not. Go to Library=>Application Support=>iPhone Simulator=>folder named your version of simulator iOS=>Applications=>Find the right folder of your project=>Documents see if the plist file is there
I want to copy set of files from project resource folder to the app document folder automatically at the time of app first launch. Can I do this. Do I need to do it through the code.
BOOL success;
NSError *error;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *documentsDirectory = [NSHomeDirectory() stringByAppendingPathComponent:#"Documents"];
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:#"Data.txt"];
success = [fileManager fileExistsAtPath:filePath];
if (!success) {
NSString *path = [[NSBundle mainBundle] pathForResource:#"Data" ofType:#"txt"];
success = [fileManager copyItemAtPath:path toPath:filePath error:&error];
}
In application did finish launching with options
This is probably a very easy problem to solve but i have not succeeded. I have copied the file "questions_famquiz_easy_110326.txt" to the resources folder and now want to access (read) it and NSLog it to see that i am able to read it.
The code below is from one of the tests i have done based on examples that i have found on the web.
I am trying to access a txt-file in the Resources folder and fail to do so. I have searched for a solution, tested a lot, but not succeeded.
I am testing with the following code:
NSLog(#"\n \n >>>>>>viewDidLoad<<<<<<<<<");
NSError *error;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *docsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [docsDirectory stringByAppendingPathComponent:#"questions_famquiz_easy_110326.txt"];
if(![fileManager fileExistsAtPath:filePath])
{
NSData *data = [NSData dataWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingString:#"/questions_famquiz_easy_110326.txt"]];
[data writeToFile:filePath atomically:YES];
}
NSString *myString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
NSLog(#"myString: %#", myString);
NSLog(#"\n \n>>>>>>DONE WITH viewDidLoad<<<<<<<<<");
exit(0); //====EXIT JUST FOR THE TEST====<<<
The above code is located in the first viewController that is started.
The output i get is:
>>>>>>viewDidLoad<<<<<<<<<
2011-04-24 21:53:47.825 FamQuiz_R0_1[542:307] myString: (null)
2011-04-24 21:53:51.044 FamQuiz_R0_1[542:307]
>>>>>>DONE WITH viewDidLoad<<<<<<<<<
Could someone nice help me to solve this?
update:
Here is the filePath:
2011-04-24 22:38:08.562 FamQuiz_R0_1[637:307] filePath: /var/mobile/Applications/7F5FDB03-0D22-46BC-91BC-4D268EB4BBEB/FamQuiz_R0_1.app/questions_famquiz_easy_110326.txt
Here is where i have placed the file:
PROBLEM SOLVED:
NSString *myString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];
When i used the above it did not work, when i used the below it worked and printed out the text.
NSString *myString = [[NSString alloc] initWithContentsOfFile:filePath];
You're not reading from the resources folder. You're trying to read from the document directory. So getting back nil makes sense since the file doesn't exist there.
Change:
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *docsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *filePath = [docsDirectory stringByAppendingPathComponent:#"questions_famquiz_easy_110326.txt"];
to:
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"questions_famquiz_easy_110326" ofType:#"txt"];
and it should work for you.
This code works beautifully to save my plist to the documents directory.
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationItem.rightBarButtonItem = self.addButtonItem;
NSString *path = [[NSBundle mainBundle] pathForResource:#"TitleArray" ofType:#"plist"];
NSMutableArray *tmpArray = [[NSMutableArray alloc]initWithContentsOfFile:path];
self.titles = tmpArray;
[tmpArray release];
//TESTING NEW CODE FOR SAVING TO DOC DIR
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *docDirPath = [documentsDirectory stringByAppendingPathComponent:#"TitleArray.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath: docDirPath])
{
NSString *bundle = [[NSBundle mainBundle] pathForResource:#"TitleArray" ofType:#"plist"];
[fileManager copyItemAtPath:bundle toPath:docDirPath error:&error];
NSLog(#"plist is copied to Directory");
}
I have not been able to figure out how to load the plist back to the app!
Can anyone help? Thanks.
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"TitleArray.plist"];
NSArray * myList = [NSArray arrayWithContentsOfFile:path];
NSMutableArray *tmpArray = [myList mutableCopy];
self.titles = tmpArray;
[tmpArray release];
didn't work?
If you are asking how to overwrite a plist included in your app's main bundle, then you should know that it cannot be done. Take a look at this question for more details: Can you update a file in the application bundle?
NSError *error; NSArray *paths =
NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *docDirPath = [documentsDirectory stringByAppendingPathComponent:#"TitleArray.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if(![fileManager fileExistsAtPath: docDirPath])
{
docDirPath = [[NSBundle mainBundle] pathForResource:#"TitleArray" ofType:#"plist"];
}
NSMutableArray *tmpArray = [[[NSMutableArray alloc] initWithContentsOfFile: docDirPath] mutableCopy];
