In my project I need to create and send a vCard (vcf file) that must include an image too. I did everything right except I can not add image to the vCard. I have shared my code below.

I am working on a chat application where I am going to send a map to another user.
Below is my code to generate a thumbnail of a map. Is there any way to generate a map thumbnail in Objective-C?
Code to generate thumbnail of static map:
NSString *staticMapUrl = [NSString stringWithFormat:#"http://maps.google.com/maps/api/staticmap?markers=color:blue|%#,%#&%#&sensor=true",_lat, _longi,#"zoom=13&size=%dx%d"];
NSURL *mapUrl = [NSURL URLWithString:[staticMapUrl stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
UIImage *Mapimage = [UIImage imageWithData: [NSData dataWithContentsOfURL:mapUrl]];
Save thumbnail images in document directories:
NSString *datapathMap=[Locations stringByAppendingPathComponent:[NSString stringWithFormat:#"Sm_%#_lc_%#.jpg",userid,dateString1]];
NSData *urlData = [NSData dataWithContentsOfURL:mapUrl];
datapathMap = [datapathMap stringByStandardizingPath];
[urlData writeToFile:datapathMap atomically:YES];
Send thumbnail data to bubble to display thumbnail:
NSBubbleData *MapSendBubble = [NSBubbleData dataWithImage:mapImage date:[NSDate date] type:BubbleTypeMine];
MapSendBubble.avatar = [UIImage imageNamed:#"avatar1.png"];
[bubbleData addObject:MapSendBubble];
[_bubbleTable reloadData];
Send map:
NSDate *today=[NSDate date];
NSDateFormatter *dateFormat1 = [[NSDateFormatter alloc] init];
[dateFormat1 setDateFormat:#"YYYYMMddhhmmss"];
NSString *dateString1=[dateFormat1 stringFromDate:today];
NSString *userid= #"mc1"; NSString *latlong=[NSString stringWithFormat:#"%#%#",[_lat substringToIndex:2],[_longi substringToIndex:2]];

I'm using this code the load the local sqlite database.
- (id)init
{
self = [super init];
if (self) {
NSString *path = [[NSBundle mainBundle] pathForResource:#"db" ofType:#"sqlite3"];
_db = [[MDDatabase alloc] initWithPath:path];
_HTMLRenderer = [[MDHTMLRenderer alloc] init];
}
return self;
}
I would like to put the database online and let the app download the database instead. I changed the code to:
NSData *dbFile = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://www.someurl.com/DatabaseName.sqlite"]];
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:#"Database.sqlite"];
[dbFile writeToFile:filePath atomically:YES];
_db = [[MDDatabase alloc] initWithPath:filePath];
_HTMLRenderer = [[MDHTMLRenderer alloc] init];
Editted:
I changed my code to follow but it's crashed.
- (id)init
{
self = [super init];
if (self) {
[self performSelectorOnMainThread:#selector(downalod) withObject:nil waitUntilDone:YES];
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:#"Database.sqlite"];
_db = [[MDDatabase alloc] initWithPath:filePath];
_HTMLRenderer = [[MDHTMLRenderer alloc] init];
}
return self;
}
-(void)download
{
NSData *dbFile = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://www.someurl.com/DatabaseName.sqlite"]];
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"Documents"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:#"Database.sqlite"];
[dbFile writeToFile:filePath atomically:YES];
}
You have problem in your file. Check with correct url. Its an encoding issue. Try with this (It will work) : http://spaceflight.nasa.gov/gallery/images/apollo/apollo17/hires/s72-55482.jpg
Add App Transport Security Settings (Allow Arbitrary Loads YES) in your plist.
Enable background mode.
Declare this macro in .m
#define DocumentsDirectory [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]
Now call and you will have the file in your local.
Call like:
[self performSelectorOnMainThread:#selector(downalod) withObject:nil waitUntilDone:NO];
_db = [[MDDatabase alloc] initWithPath:filePath];
_HTMLRenderer = [[MDHTMLRenderer alloc] init];
-(void)download
{
NSString *stringURL =[NSString stringWithFormat: #"url"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#",[stringURL stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
NSString *filePath = [DocumentsDirectory stringByAppendingPathComponent:[url lastPathComponent]];
NSLog(#"success--222,%#", filePath);
[NSURLConnection sendAsynchronousRequest:urlRequest queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
{
NSLog(#"success--222,%#", filePath);
if (error)
{
NSLog(#"success--not---Error,%#", [error localizedDescription]);
}
else
{
NSLog(#"success--yes... %#", [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding]);
[data writeToFile:filePath atomically:YES];
}
}];
}
After long time search, finally I solved it myself:
- (id)init
{
self = [super init];
if (self) {
NSData *fetchedData = [NSData dataWithContentsOfURL:[NSURL URLWithString:#"http://www.someurl.com/db.sqlite3"]];
NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *filePath = [documentsPath stringByAppendingPathComponent:#"db.sqlite3"];
[fetchedData writeToFile:filePath atomically:YES];
_db = [[MDDatabase alloc] initWithPath:filePath];
_HTMLRenderer = [[MDHTMLRenderer alloc] init];
}
return self;
}
I have created a simple plist file with some user preferences for a card game I'm writing.
I have also created a controller that reads and writes to this plist file which is a singelton.
everything works fine, but then after a couple of tries it stops working.
Logging the values to the console it shows the list returning a value of 0 which causes my app to crash
I have deleted the plist and created a new one and then the same story, works fine for 2 or three time and then boom zero.
here is a copy of the controller singelton code:
#implementation userOptionsController
static userOptionsController* _sharedOptionsController = nil;
#synthesize backgroundSound=_backgroundSound;
#synthesize soundEffects = _soundEffects;
#synthesize coach = _coach;
#synthesize numberOfDecks = _numberOfDecks ;
+(userOptionsController*)sharedOptionsController{
#synchronized([userOptionsController class])
{
if(!_sharedOptionsController)
[[self alloc]init];
return _sharedOptionsController;
}
return nil;
}
+(id)alloc
{
#synchronized ([userOptionsController class])
{
NSAssert(_sharedOptionsController == nil, #"Attempted to allocate a second instance of userOptionsController singleton");
_sharedOptionsController = [super alloc];
return _sharedOptionsController;
}
return nil;
}
- (id) init {
self = [super init];
if (self) {
}
return self;
}
-(void)readPlistFile
{
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"playerPrefOptions.plist"];
NSFileManager *fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath: path])
{
NSString *bundle = [[NSBundle mainBundle] pathForResource:#"playerPrefOptions" ofType:#"plist"];
[fileManager copyItemAtPath:bundle toPath: path error:&error];
}
NSMutableDictionary *temp = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
self.backgroundSound = [[temp objectForKey:#"backgroundSounds"]boolValue];
self.soundEffects = [[temp objectForKey:#"soundEffects"]boolValue];
self.coach =[[temp objectForKey:#"coach"]boolValue];
self.numberOfDecks = [[temp objectForKey:#"numberOfDecks"]intValue];
}
-(void)writeOptionsToFile
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:#"playerPrefOptions.plist"];
NSMutableDictionary *infoDict = [[NSMutableDictionary alloc] initWithContentsOfFile: path];
NSNumber *moshe = [NSNumber numberWithInt:self.numberOfDecks];
[infoDict setObject: moshe forKey:#"numberOfDecks"];
[infoDict setObject:[NSNumber numberWithBool:self.coach] forKey:#"coach"];
[infoDict setObject:[NSNumber numberWithBool:self.backgroundSound] forKey:#"backgroundSounds"];
[infoDict setObject:[NSNumber numberWithBool:self.soundEffects] forKey:#"soundEffects"];
[infoDict writeToFile:path atomically:YES];
}
#end
so the property :
int numberOfDecks =[userOptionsController sharedOptionsController].numberOfDecks;
will return zero.
any ideas?
thanks.
Rather than use a plist for this content, it looks like NSUserDefaults is a more appropriate location.
Instead of shipping the app with a default plist file, instead just registerDefaults: with NSUserDefaults (often done in your app delegate application:didFinishLaunchingWithOptions:).
Then, whenever any changes are made just update NSUserDefaults and call synchronize to save the changes.
Try this and see what it does (what logs are output):
#implementation userOptionsController
+ (userOptionsController*)sharedOptionsController
{
static dispatch_once_t pred = 0;
__strong static id _sharedObject = nil;
dispatch_once(&pred, ^{
_sharedObject = [[self alloc] init];
});
return _sharedObject;
}
- (id) init {
self = [super init];
if (self) {
}
return self;
}

I can't save my new data to plist file for some reason. This is code I have been using for saving data:
-(void)saveData:(NSMutableDictionary *)dictionaryData toFile:(NSString *)filename {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *path = [docDir stringByAppendingPathComponent:filename];
NSMutableArray *data = [[NSMutableArray alloc] initWithContentsOfFile:path];
[data addObject:dictionaryData];
[data writeToFile:filename atomically:YES];
}
this is code I used to copy file from bundle to app directory in case if it is not there :
-(NSMutableArray *)loadFromFile:(NSString *)filename {
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDir = [paths objectAtIndex:0];
NSString *path = [docDir stringByAppendingPathComponent:filename];
NSFileManager *fileMgr = [NSFileManager defaultManager];
if(![fileMgr fileExistsAtPath:path]) {
NSArray *fileArray = [filename componentsSeparatedByString:#"."];
NSString *name = [fileArray objectAtIndex:0];
NSString *ext = [fileArray objectAtIndex:1];
NSString *bundle = [[NSBundle mainBundle] pathForResource:name ofType:ext];
[fileMgr copyItemAtPath:bundle toPath:path error:&error];
}
NSMutableArray *data = [[NSMutableArray alloc] initWithContentsOfFile:path];
return data;
}
For some reason I can't save new data to plist file. When I try to add new NSMutableDictionary object to my plist file (with saveData:toFile: method) and than reload my array variable with the plist file data - new object is not there. Am I doing something wrong?
this is how I load plist file :
#property (nonatomic, strong) NSMutableArray *modules;
#property (nonatomic, strong) NSMutableDictionary *module;
- (void)viewDidLoad {
[super viewDidLoad];
self.modules = [self loadFromFile:#"ModulesList.plist"];
self.module = [self.modules objectAtIndex:0];
for (int i = 0; i < self.modules.count; i++ ) {
NSLog(#"Modules array from plist file, module at index %i : %#",i, [self.modules objectAtIndex:i]);
}
than for testing purpose I have this code to add new module object:
- (IBAction)leftButton:(id)sender {
NSString *mytitle = [[NSString alloc] initWithFormat:#"my title"];
NSString *myauthor = [[NSString alloc] initWithFormat:#"my author2"];
NSUInteger myean = 22023423;
NSString *mytitle2 = [[NSString alloc] initWithFormat:#"my title 2"];
NSString *myauthor2 = [[NSString alloc] initWithFormat:#"my author2"];
NSUInteger myean2 = 29032432;
NSString *mytitle3 = [[NSString alloc] initWithFormat:#"my title 3"];
NSString *myauthor3 = [[NSString alloc] initWithFormat:#"my author 3"];
NSUInteger myean3 = 21023423;
NSMutableDictionary *mybook = [[NSMutableDictionary alloc] init];
NSMutableDictionary *mybook2 = [[NSMutableDictionary alloc] init];
NSMutableDictionary *mybook3 = [[NSMutableDictionary alloc] init];
[mybook setObject:mytitle forKey:#"title"];
[mybook setObject:myauthor forKey:#"author"];
[mybook setObject:[NSNumber numberWithInteger:myean] forKey:#"ean"];
[mybook2 setObject:mytitle2 forKey:#"title"];
[mybook2 setObject:myauthor2 forKey:#"author"];
[mybook2 setObject:[NSNumber numberWithInteger:myean2] forKey:#"ean"];
[mybook3 setObject:mytitle3 forKey:#"title"];
[mybook3 setObject:myauthor3 forKey:#"author"];
[mybook3 setObject:[NSNumber numberWithInteger:myean3] forKey:#"ean"];
NSMutableArray *mybooks = [[NSMutableArray alloc] init];
[mybooks addObject:mybook];
[mybooks addObject:mybook2];
[mybooks addObject:mybook3];
[self.module setObject:mybooks forKey:#"books"];
[self.modules addObject:self.module];
for (int i = 0; i < self.modules.count; i++ ) {
NSLog(#"Modules array after add operation, module at index: %i: %#",i, [self.modules objectAtIndex:i]);
}
[self saveData:self.module toFile:#"ModulesList.plist"];
}
than when I will reload my self.modules array from plist with button action, my new data is not there:
- (IBAction)reload:(id)sender {
self.modules = [self loadFromFile:#"ModulesList.plist"];
for (int i = 0; i < self.modules.count; i++ ) {
NSLog(#"RELOAD: Modules array from plist file, module at index %i : %#",i,[self.modules objectAtIndex:i]);
}
}
this is screenshot of my plist file : http://dl.dropbox.com/u/49076351/Screen%20Shot%202013-02-27%20at%2016.27.45.png
I have a UITableView populated by a feed from searchtwitter.com. I also have a details table with an image and UILabel. I have all this working, but I want to add a UIButton on the detail page that will save the UIImage and the label into a property list. I'm very new to this; here is what I have so far (not working).
- (IBAction)SaveFriend:(id)sender
{
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentDirectory = [path objectAtIndex:0];
NSString *plistPath = [documentDirectory stringByAppendingPathComponent:#"TwitterFriends.plist"];
NSDictionary * tweet = [[NSDictionary alloc]init];
NSString *text = [tweet objectForKey:#"from_user"];
NSString *user = [tweet objectForKey:#"from_user_name"];
personName.text = text;
personInfo.text = user;
// create dictionary with values in UITextFields
NSDictionary *plistDict = [NSDictionary dictionaryWithObjects: [NSArray arrayWithObjects: personName, personInfo, nil] forKeys:[NSArray arrayWithObjects: #"Name", #"info", nil]];
NSString *error = nil;
// create NSData from dictionary
NSData *plistData = [NSPropertyListSerialization dataFromPropertyList:plistDict format:NSPropertyListXMLFormat_v1_0 errorDescription:&error];
// check is plistData exists
if(plistData)
{
// write plistData to our Data.plist file
[tweet writeToFile:plistPath atomically:YES];
}
else
{
NSLog(#"Error in saveData: %#", error);
[error release];
}
}
Instead of using a .plist, try using an NSArray or NSMutableArray and then the writeToFile method. For example:
NSMutableArray *temp = [NSMutableArray new];
[temp addObject:image];
[temp addObject:label];
[temp writeToFile:[self saveFilePath:#"filename"] atomically:YES];
//Returns the saved information path
- (NSString*) saveFilePath: (NSString *) add
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *path = [paths objectAtIndex:0];
NSString *filename = [path stringByAppendingPathComponent:add];
return filename;
}
