Once plist is created data storing start automatically, but after some time it automatically stop storing data in plist. But once when i kill app and restart again, it will start again as previously mention and cycle goes on...
Here is my code
- (void)saveLocationsToPlist:(NSMutableDictionary*)mdictPlist {
NSString *plistName = [NSString stringWithFormat:#"LocationArray.plist"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *fullPath = [NSString stringWithFormat:#"%#/%#", docDir, plistName];
NSMutableDictionary *savedProfile = [[NSMutableDictionary alloc] initWithContentsOfFile:fullPath];
NSLog(#"ADD LOCATION TIME : %#",[NSDate date]);
NSLog(#"ADD LOCATION DATA : %#",mdictPlist);
if (![[NSFileManager defaultManager] fileExistsAtPath:fullPath]){
BFLog(#"applicationDocumentsDir Not exists");
fullPath = [docDir stringByAppendingPathComponent: [NSString stringWithFormat:#"LocationArray.plist"] ];
}
if (!savedProfile) {
savedProfile = [[NSMutableDictionary alloc] init];
self.myLocationArrayInPlist = [[NSMutableArray alloc]init];
} else {
self.myLocationArrayInPlist = [savedProfile objectForKey:#"LocationArray"];
}
if(mdictPlist) {
if(self.myLocationArrayInPlist == nil){
self.myLocationArrayInPlist = [[NSMutableArray alloc]init];
}
[_myLocationArrayInPlist addObject:mdictPlist];
[savedProfile setObject:_myLocationArrayInPlist forKey:#"LocationArray"];
}
if (![savedProfile writeToFile:fullPath atomically:FALSE]) {
BFLog(#"Couldn't save LocationArray.plist savedProfile :- %# \n Location Data :- %# \n fullPath:-%#",savedProfile,mdictPlist,fullPath);
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectoryPath = [paths objectAtIndex:0];
NSFileManager *fm = [NSFileManager defaultManager];
NSString *directory = [documentsDirectoryPath stringByAppendingPathComponent:#""];
NSError *error = nil;
for (NSString *file in [fm contentsOfDirectoryAtPath:directory error:&error]) {
NSLog(#"%#",[NSString stringWithFormat:#"%#/%#", directory, file]);
if([file isEqualToString:#"LocationArray.plist"]){
BOOL success = [fm removeItemAtPath:[NSString stringWithFormat:#"%#/%#", directory, file] error:&error];
if (!success || error) {
// it failed.
BFLog(#"Delete error : %#",error);
}
else {
[self saveLocationsToPlist:myLocationDictInPlist];
}
}
}
}
}
Any idea about this issue.

I'm receiving a String from a web service and I would like to store it as a pdf file.
I know the have asked before but the answer is always the same. I've tryed it and didn't worked, and it's not explained enough.
So, this is what I'm doing:
NSData *data = [documentString dataUsingEncoding:NSUTF8StringEncoding];
NSString *formattedName = [NSString stringWithFormat:#"%#.pdf", name];
NSString *pdfPath = [#"documents/" stringByAppendingPathComponent:formattedName];
NSError *error = nil;
if([data writeToFile:pdfPath options:NSDataWritingAtomic error:&error]) {
}
It's not entering in the if, and I think the file is not being generated.
I'm working with objective-c, xcode 9.
What should I modify?
Create it
NSError*error=nil;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"/Application Support"];

I want to store .zip files on iCloud. Anybody help me how to upload and restore? I have read the Apple guideline for iCloud backup and now I have created one folder with some files and two folders with multiple images and then generate zip file of that folder.
First Save your File and Folder on Local Storage.
Then Create this File & Folder's Zip File.
And Last Upload Your zip file on iCloud.
For get this file doing reverse process.

could someone point out what I am doing wrong.

FWIW, here is what worked for me:

if ([fileManager fileExistsAtPath: [self filePathForState]])
{
printf("found state file\n");
NSData *data = [NSData dataWithContentsOfFile:[self filePathForState]];

}
else
{

}
[fileManager release];

return result;
}

}
I want to create a file in my application document folder and i have to store some content. That content takes from my localhost file. So i write a below code. But this code didn't create a file in my application document folder.
- (void) createFile

NSData *data =[NSData dataWithContentsOfURL:[NSURL URLWithString:strPath]];

NSString *folderName = [#"Object File/" stringByAppendingString:strLastpath];
NSLog(#"Path : %# \n File Name : %#",strPath,folderName);
NSArray *dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docsDir = [dirPaths objectAtIndex:0];
databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent:folderName]];
NSLog(#"Database Path : %#",databasePath);
NSFileManager *filemgr = [NSFileManager defaultManager];
if ([filemgr fileExistsAtPath:databasePath] == YES)
{
NSLog(#"File Exists");
}
else
{
NSLog(#"File not exists");
}
NSString *content = [NSString stringWithFormat:#"%#",data];
[content writeToFile:strLastpath atomically:NO encoding:NSStringEncodingConversionAllowLossy error:nil];
}
While build for running i got this.

You can also try this code
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
NSString *fileName = #"yourFileName";
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:#"/fileName"];
NSDate *data = [NSData dataWithContentsOfURL:YourUrl]; // get date form url
[data writeToFile:dataPath atomically:YES]; // save data in file
I found the answer. File created successfully.

NSString *strPath = [NSString stringWithFormat:#"http://-.-.-.-/~mac/banana.obj"];

I am trying to add and array to a Root array in my plist:
And is not working. Here's my code:
-(IBAction)addName:(id)sender{
NSArray *arrayValues = [NSArray arrayWithObjects: nameLabel.text, nameDate.text, nameValue.text, nil];
NSString *plistpath = [[NSBundle mainBundle] pathForResource:#"Names" ofType:#"plist"];
NSMutableArray *namesNew = [[NSMutableArray alloc] initWithContentsOfFile:plistpath];
[namesNew addObject:arrayValues];
[namesNew writeToFile:plistpath atomically:YES];
}
What am I doing wrong? Thanks!
You need to move the file to NSDocumentDirectory. Then edit the plist file.
For example:
Moving to NSDocumentDirectory:
-(NSDictionary *)copyBundleToDocuments
{
NSFileManager *fileManager = [NSFileManager defaultManager];
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [documentPaths objectAtIndex:0];
NSString *documentPlistPath = [documentsDirectory stringByAppendingPathComponent:#"Names.plist"];
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
NSString *bundlePlistPath = [bundlePath stringByAppendingPathComponent:#"Names.plist"];
//if file exists in the documents directory, get it
if([fileManager fileExistsAtPath:documentPlistPath])
{
NSMutableDictionary *documentDict = [NSMutableDictionary dictionaryWithContentsOfFile:documentPlistPath];
return documentDict;
}
//if file does not exist, create it from existing plist
else
{
NSError *error;
BOOL success = [fileManager copyItemAtPath:bundlePlistPath toPath:documentPlistPath error:&error];
if (success) {
NSMutableDictionary *documentDict = [NSMutableDictionary dictionaryWithContentsOfFile:documentPlistPath];
return documentDict;
}
return nil;
}
}
Then get the plist:
-(void)plistArray:(NSArray*)array
{
//get the documents directory:
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
//getting the plist file name:
NSString *plistName = [NSString stringWithFormat:#"%#/Names.plist",
documentsDirectory];
NSMutableArray *namesNew = [[NSMutableArray alloc] initWithContentsOfFile:plistName];
[namesNew addObject:arrayValues];
[namesNew writeToFile:plistName atomically:YES];
return nil;
}
The plist should be a dictionary as the base object instead of an array.
NSMutableDictionary *namesNew = [NSMutableDictionary dictionaryWithContentsOfFile:plistpath];
[namesNew setObject: arrayValues forKey: #"Root"];
[namesNew writeToFile:plistpath atomically:YES];
You cant write your plist to the bundle you need to use NSDocumentDirectory or NSCachesDirectory
Just copy your plist to bundle the overwrite it.
Note: learn the difference between NSCachesDirectory and NSDocumentDirectory
https://developer.apple.com/icloud/documentation/data-storage/
Copy your plist from bundle to documents(in below code caches), you need to this only one time if your plist in your bundle, I prefer using this code in appdelegate.m when - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *sourcePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"Names.plist"];
NSString *plistInDocuments=#"Names.plist";
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:plistInDocuments];
NSError *error = nil;
if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath]){
[[NSFileManager defaultManager] copyItemAtPath:sourcePath
toPath:dataPath
error:&error];
}
NSLog(#"Error description-%# \n", [error localizedDescription]);
NSLog(#"Error reason-%#", [error localizedFailureReason]);
Get your file and overwrite it
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *plistInDocuments=#"Names.plist";
NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:plistInDocuments];
//add object here
NSMutableArray *namesNew = [[NSMutableArray alloc] initWithContentsOfFile:dataPath];
[namesNew addObject:arrayValues];
NSError *error = nil;
if ([myFile writeToFile:dataPath options:NSDataWritingAtomic error:&error]) {
// file saved
} else {
// error writing file
NSLog(#"Unable to write plist to %#. Error: %#", dataPath, error);
}
