I am trying to do a simple update to a sqlite database using EGODatabase and although the code runs the update does not occur?
NSArray *params = [NSArray arrayWithObjects:#"TEST", nil];
EGODatabase *database = [EGODatabase databaseWithPath:[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"db_USBV1.sqlite3"]];
[database executeQuery:#"update users set locked = 0 where UID = ?" parameters:params ];
I saw on previous post that must copy the db to the users directory which i am doing as below;
NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:#"db_USBV1.sqlite3"];
NSFileManager *fileManager = [[NSFileManager alloc] init];
if (![fileManager fileExistsAtPath:filePath]) {
NSError *error = nil;
[fileManager copyItemAtPath:[[NSBundle mainBundle] pathForResource:#"db_USBV1" ofType:#"sqlite3"] toPath:filePath error:&error];
}
[fileManager release];
But update is not occurring.
Any help much appreciated.
Thanks,
Mike
Thanks for the pointers. I was still attempting to work with the file in the bundle and not the file that was copied.

i have a problem when creating a txt file from a for statement. Here is the code of the statement on a CoreData.
NSManagedObjectContext *context = [self managedObjectContext];
NSFetchRequest * allTickets = [[NSFetchRequest alloc] init];
[allTickets setEntity:[NSEntityDescription entityForName:#"Place" inManagedObjectContext:context]];
[allTickets setIncludesPropertyValues:NO];
NSError * error = nil;
NSArray * ticks = [context executeFetchRequest:allTickets error:&error];
for (NSManagedObject * tick in ticks) {
NSArray *keys = [[[tick entity] attributesByName] allKeys];
NSDictionary *myDict = [tick dictionaryWithValuesForKeys:keys];
NSString *theDate = [myDict objectForKey:#"date"];
NSString *theName = [myDict objectForKey:#"name"];
NSString *theNumber = [myDict objectForKey:#"number"];
NSString * finalExport = [NSString stringWithFormat:#"%#%#%#", theDate, theName, theNumber];
NSLog(#"%#",finalExport);
the NSLog result print out all the entries in CoreData correctly, running each request one after the other.
My problem is that when i want to create a txt with the finalExport NSString, i only have the first request in the file.
For exemple i got an NSLog with :
01.01.2015 MYNAME 34555445
02.01.2015 MYNAME 34523445
03.01.2015 MYNAME 34115445
04.01.2015 MYNAME 34552345
But in the text file i only got
01.01.2015 MYNAME 34555445
So how can i have a text file with all the NSLog Results
Thanks in advance for your help ;)

Here is the rest of the code :
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory
NSError *error;
BOOL succeed = [finalExport writeToFile:[documentsDirectory stringByAppendingPathComponent:#"Number.txt"]
atomically:YES encoding:NSUTF8StringEncoding error:&error];
if (!succeed){
NSLog(#"NOT WORKING");
}
You need to make sure you write an array of entries to the file, not just one entry.
I have a graphical application with some predefined tool configurations. At the first lunch of the application I would like to copy these default configuration files into ~/Library/Containers//Data/Library/... from the inside of the bundle. How to do that?
Try this it'll help you.
-(void)copy
{
NSFileManager *filemanager = [NSFileManager defaultManager];
NSError *error;
NSString *path = [self getPath];
BOOL sucess = [filemanager fileExistsAtPath:path];
if(!sucess){
NSString *defaultPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"/*put your assets name with extension here */"];
sucess = [filemanager copyItemAtPath:defaultPath toPath:path error:&error];
if (!sucess) {
NSAssert1(0, #"Failed '%#'.", [error localizedDescription]);
}
}
}
-(NSString *) getPath{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
return [documentsDir stringByAppendingPathComponent:#"/*put your assets name with extension here */"];
}
I have an iPad that has a routine to create a pdf and send as an attachment to an email. It all seems to work with the email composer opening showing the pdf document attached. However when tested on an iPad, when the email is received there is no attachment. Any ideas?
[mailComposer addAttachmentData:data mimeType:#"application/pdf" fileName:#"pdffile.pdf"];
[self presentViewController:mailComposer animated:YES completion:nil];
Many thanks
Detail:
The pdf file is created and called pdffile.pdf. The following is the full email routine:
MFMailComposeViewController *mailComposer;
mailComposer = [[MFMailComposeViewController alloc] init];
mailComposer.mailComposeDelegate = self;
[mailComposer setModalPresentationStyle:UIModalPresentationFormSheet];
[mailComposer setSubject:[NSString stringWithFormat: #"i-observe Lesson Observation for: %s", "date"]];
[mailComposer setMessageBody:[NSString stringWithFormat: #"i-observe Lesson Observation for: %s", "name"] isHTML:NO];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *file = [documentsDirectory stringByAppendingFormat:#"pdffile.pdf"];
NSMutableData *data=[NSMutableData dataWithContentsOfFile:file];
[mailComposer addAttachmentData:data mimeType:#"application/pdf" fileName:#"pdffile.pdf"];
[self presentViewController:mailComposer animated:YES completion:nil];
Try This Method:
if([MFMailComposeViewController canSendMail]){
MFMailComposeViewController *mail=[[MFMailComposeViewController alloc]init];
mail.mailComposeDelegate=self;
[mail setSubject:#"Email with attached pdf"];
NSString *newFilePath = #"get path where the pdf reside";
NSData * pdfData = [NSData dataWithContentsOfFile:newFilePath];
[mail addAttachmentData:pdfData mimeType:#"application/pdf" fileName:#"yourpdfname.pdf"];
NSString * body = #"";
[mail setMessageBody:body isHTML:NO];
[self presentModalViewController:mail animated:YES];
[mail release];
}
else
{
NSLog(#"Message cannot be sent");
}
The next solutions is based assuming that the pdf file is in your main bundle:
NSBundle *mainBundle = [NSBundle mainBundle];
NSString *myFile = [mainBundle pathForResource: #"RealNameofFile" ofType: #"pdf"];
NSData *pdfD = [NSData dataWithContentsOfFile:myFile];
[mailViewController addAttachmentData:pdfData mimeType:#"application/pdf" fileName:#"Nametodisplayattached.pdf"];
make sure that the file has the same name as the table cell
I've been trying to write data back to a pre-defined plist file (data.plist) in my bundle. Using the code below I call the routine 'dictionaryFromPlist' to open the file and then call 'writeDictionaryToPlist' to write to the plist file. However, no data gets added to the plist file.
NSDictionary *dict = [self dictionaryFromPlist];
NSString *key = #"Reports";
NSString *value = #"TestingTesting";
[dict setValue:value forKey:key];
[self writeDictionaryToPlist:dict];
- (NSMutableDictionary*)dictionaryFromPlist {
NSString *filePath = [[NSBundle mainBundle] pathForResource:#"data" ofType:#"plist"];
NSMutableDictionary* propertyListValues = [[NSMutableDictionary alloc]
initWithContentsOfFile:filePath];
return [propertyListValues autorelease];
}
- (BOOL)writeDictionaryToPlist:(NSDictionary*)plistDict{
NSString *filePath = #"data.plist";
BOOL result = [plistDict writeToFile:filePath atomically:YES];
return result;
}
The code runs through successfully and no error is thrown but no data is added to my plist file.
You can not write to your bundle, it is read only. If your case though, you are writing to a relative path, not to the bundle.
I'm not sure what the default working directory is for iOS apps. It is best to use absolute paths. You should be writing to the documents/cache directory. Something like this will get the path for you:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
Then just grab the lastObject and prepend that to your file name.
As mentioned by #logancautrell you can not write in mainbundle, you can save your plist in the app documents folder, you could do so:
NSString *path = #"example.plist";
NSArray *paths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
NSString *basePath = ([paths count]> 0)? [paths objectAtIndex: 0]: nil;
NSString *documentPath = [basePath stringByAppendingPathComponent:path] // Documents
NSFileManager *fileManager = [NSFileManager defaultManager];
BOOL checkfile = [fileManager fileExistsAtPath: documentPath];
NSLog(#"%#", (checkFile ? #"Exist": #"Not exist"));//check if exist
if(!checkfile) {//if not exist
BOOL copyFileToDoc = [yourDictionary writeToFile:documentPath atomically: YES];
NSLog(#"%#",(copyFileToDoc ? #"Copied": #"Not copied"));
}
I'm making an app where I need to copy certain file from the app bundle to the user's Application Support folder. This is the code I'm using actually:
NSBundle *thisBundle = [NSBundle mainBundle];
NSString *executableName = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleExecutable"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
NSString *userpath = [paths objectAtIndex:0];
userpath = [userpath stringByAppendingPathComponent:executableName]; // The file will go in this directory
NSString *saveFilePath = [userpath stringByAppendingPathComponent:#"db.sqlite"];
NSFileManager *fileManager = [[NSFileManager alloc] init];
[fileManager copyItemAtPath:[thisBundle pathForResource:#"db" ofType:#"sqlite"] toPath:saveFilePath error:NULL];
But this doesn't copies anything, BTW this is a Mac app.
Finally got it working with adding
if ([fileManager fileExistsAtPath:userpath] == NO)
[fileManager createDirectoryAtPath:userpath withIntermediateDirectories:YES attributes:nil error:nil];
And the resulting code is:
NSBundle *thisBundle = [NSBundle mainBundle];
NSString *executableName = [[[NSBundle mainBundle] infoDictionary] objectForKey:#"CFBundleExecutable"];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSApplicationSupportDirectory, NSUserDomainMask, YES);
NSString *userpath = [paths objectAtIndex:0];
userpath = [userpath stringByAppendingPathComponent:executableName]; // The file will go in this directory
NSString *saveFilePath = [userpath stringByAppendingPathComponent:#"db.sqlite"];
NSFileManager *fileManager = [[NSFileManager alloc] init];
if ([fileManager fileExistsAtPath:userpath] == NO)
[fileManager createDirectoryAtPath:userpath withIntermediateDirectories:YES attributes:nil error:nil];
[fileManager copyItemAtPath:[thisBundle pathForResource:#"db" ofType:#"sqlite"] toPath:saveFilePath error:NULL];
You might want to double-check your file paths:
NSLog(#"src: %#", [thisBundle pathForResource:#"db" ofType:#"sqlite"]);
NSLog(#"dst: %#", saveFilePath);
