In my Application,I am taking screenshots of image View and then I am saving those screen shots in document folder of the application.Now I want to Email all those images with the same folder structure they are in.Zipping all the folders containing the images?
-(void)ZipFile2{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *docDirectory = [paths objectAtIndex:0];
BOOL isDir=NO;
NSArray *subpaths;
NSString *exportPath = docDirectory;
NSFileManager *fileManager = [NSFileManager defaultManager];
if ([fileManager fileExistsAtPath:exportPath isDirectory:&isDir] && isDir){
subpaths = [fileManager subpathsAtPath:exportPath];
}
NSString *archivePath = [docDirectory stringByAppendingString:#"Uploads.zip"];
ZipArchive *archiver = [[ZipArchive alloc] init];
[archiver CreateZipFile2:archivePath];
for(NSString *path in subpaths)
{
NSString *longPath = [exportPath stringByAppendingPathComponent:path];
if([fileManager fileExistsAtPath:longPath isDirectory:&isDir] && !isDir)
{
[archiver addFileToZip:longPath newname:path];
}
}
BOOL successCompressing = [archiver CloseZipFile2];
if(successCompressing)
NSLog(#"Success");
else
NSLog(#"Fail");
}
I use this code but the zip file is not created in my Ipad ??? can you Help Me
ZipArchive has a delegate protocol which sends a message whenever a error occurs.
add below ZipArchive allocation.
archiver.delegate = self
Add protocol to header class and then implement the following method:
- (void)ErrorMessage:(NSString*) msg {
NSLog(#"Zip error: %#", msg);
}

Trying to save custom objects as NSData then upload to iCloud Drive
any direction?
I tried already the Key-Value Method, but it is limited for 1MB :/
is it the correct way?
if yes, how can I read from the iCloud path?

I have an iOS app that at times needs to store UIImage objects locally.
I am using [UIImagePNGRepresentation(image) writeToFile:full_path options:NSAtomicWrite error:nil]; to save the image and [file_manager removeItemAtPath:full_path error:NULL]; to delete the file.
This all works great, however, whenever I delete a file, should I decide to save a new file (which just so happens to have the same name as the old file), the save code doesn't work and returns the following error:
: ImageIO: CGImageReadCreateDataWithMappedFile 'open' failed
error = 2 (No such file or directory)
: ImageIO: CGImageReadCreateDataWithMappedFile 'open' failed
error = 2 (No such file or directory)
: ImageIO: PNG zlib error
So heres what I don't get, why can't I save a file with the same name as the old file, after I have deleted the old file?
The reason I ask this, is that, my app will save certain image files and then when they are no longer needed, my app will delete them. However, there are times when my app needs the image files again (could be a few hours after deletion or a few weeks). When this happens, my app will load the appropriate image data and then try to save it. And thats when the error occurs.
Whats going wrong here?
Thanks for your time, Dan.
UPDATE - Here are the methods I have setup to save/access and delete my image files
-(void)save_local_image:(UIImage *)image :(NSString *)file_name {
// Get the app documents directory link.

I'm having some issue connecting to my sqlite database.. I'm using xcode version 4.4.1
here's my code..
NSString *docsDir;
NSArray *dirPaths;
// Get the documents directory
dirPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
docsDir = [dirPaths objectAtIndex:0];
// Build the path to the database file
databasePath = [[NSString alloc] initWithString: [docsDir stringByAppendingPathComponent: #"signature.db"]];
NSFileManager *filemgr = [NSFileManager defaultManager];
if ([filemgr fileExistsAtPath: databasePath ] == NO)
{
const char *dbpath = [databasePath UTF8String];
if (sqlite3_open(dbpath, &database) == SQLITE_OK)
{
status.text = #"Connected..";
} else {
status.text = #"Failed to open/create database..";
}
}
[filemgr release];
Any suggestion..?
Thanks,
Boom
There is no need to check if the database exists; sqlite3_open_v2() (reference) will create the database, if it does not exist, if you pass the flag SQLITE_OPEN_CREATE:
NSString *dbPath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPath:#"signature.db"];
if (sqlite3_open_v2([dbPath UTF8String], &database, SQLITE_OPEN_READWRITE|SQLITE_OPEN_CREATE) == SQLITE_OK)
{
status.text = #"Connected..";
// Check the schema and install if it doesn't exist
sqlite3_close(database);
} else {
status.text = #"Failed to open/create database..";
}
You may wish to check if the DB file is in place if you have one in your app's bundle that is pre-built so you can drop it into your documents folder. Of course, as you enhance your app, any schema changes will need to be done in code. Here is some code that I use (that works, but needs to updated a bit)
When opening/creating the DB I use this to specify where the DB file will be. I don't put it with the init because my location is different between iOS and Mac OS X and I want the DB code to work with both:
NSString *dbFilePath;
NSArray *searchPaths = NSSearchPathForDirectoriesInDomains (NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentFolderPath = searchPaths[0];
dbFilePath = [documentFolderPath stringByAppendingPathComponent: #"MyDBFile.db"];
MyDB* appDB = [[EasySpendLogDB alloc] initWithFile:dbFilePath];
if(!appDB) {
// show error
return;
}
This is in my DB access class. It uses some wrapper classes I wrote:
- (id) initWithFile: (NSString*) filePathName {
if(!(self = [super init])) return nil;
BOOL myPathIsDir;
BOOL fileExists = [[NSFileManager defaultManager]
fileExistsAtPath: filePathName
isDirectory: &myPathIsDir];
NSString *backupDbPath = [[NSBundle mainBundle]
pathForResource:#"MyDBFile"
ofType:#"db"];
if (backupDbPath != nil && !fileExists) {
[[NSFileManager defaultManager]
copyItemAtPath:backupDbPath
toPath:filePathName
error:nil];
}
db = [[ABSQLiteDB alloc] init];
if(![db connect:filePathName]) {
return nil;
}
[self checkSchema]; // this is where schema updates are done (see project sample)
return self;
}
You may also want to check out this objective-c wrapper I wrote that has a sample project: https://github.com/AaronBratcher/ABSQLite
Suppose I have a custom function called savePlist as below.
CommonClass.m
- (NSString *)getDirectoryPath
{
NSArray *pathList = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [pathList objectAtIndex:0];
return path;
}
- (void)savePlist:(NSString *)fileName WithArray:(NSArray *)fileArr
{
NSString *path = [[self getDirectoryPath] stringByAppendingPathComponent:fileName];
[fileArr writeToFile:path atomically:YES];
}
While I run a code as below, no plist is generated.
ABCAppDelegate.m
...
[cc savePlist:#"example.plist" WithArray:[NSArray new]];
The file of example.plist has not been generated, is there any mistakes on my code?
Thanks
UPDATE:
If I use the code as below, the xxx.plist file has been generated successfully.
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *plistFile = [[paths objectAtIndex:0] stringByAppendingPathComponent:#"abc.plist"];
NSMutableDictionary *plist = [[NSMutableDictionary alloc] initWithContentsOfFile:plistFile];
if (!plist) {
plist = [NSMutableDictionary new];
[plist writeToFile:plistFile atomically:YES];
NSLog(#"write plist");
}
Reference: link
UPDATE 2:
I change the code as below:
NSLog(#"code");
[cc savePlist:#"example.plist" WithArray:[NSArray new]];
NSLog(#"code");
- (void)savePlist:(NSString *)fileName WithArray:(NSArray *)fileArr
{
NSLog(#"fileName = %#, fileArr = %#", fileName, fileArr);
NSString *path = [[self getDirectoryPath] stringByAppendingPathComponent:fileName];
NSLog(#"path = %#", path);
[fileArr writeToFile:path atomically:YES];
}
It just print out:
2011-10-10 14:24:00.560 ABC[3390:207] code
2011-10-10 14:24:00.561 ABC[3390:207] code
No message of fileName = and fileArr =, also path = print out on the log, so the code inside savePlist have not been executed?
It looks like your common class object is not instantiated, and you are sending all those messages to nil. Try logging cc in your app delegate code, where you call this method from.
You need to create an instance of your common class, something like
cc = [[CommonClass alloc] init];
(may vary depending on your set up).
I have been trying to create a new file inside of my application support folder while using NSApplicationSupportDirectory; I can write a file to it, but I have been unable to create a folder inside of Application Support.
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSApplicationSupportDirectory, NSUserDomainMask, YES);
NSString *applicationDirectory = [paths objectAtIndex:0];
//make a file name to write the data to using the application support: (attempting to create the blasted directory inside of application support directory
NSString *fileName = [NSString stringWithFormat:#"%#/managersemail.txt",
applicationDirectory];
//create content - formats with the managersemail.txt location
NSString* content = [NSString stringWithFormat:#"%#",[nameField stringValue]];
//save content to the documents directory
[content writeToFile:fileName
atomically:NO
encoding:NSStringEncodingConversionAllowLossy
error:nil];
NSDictionary* errorDict;
The code that I have listed above works great, except for the part about creating the folder in which I want to place the managersemail.txt. I tried to mimic the stringWithFormat that is listed in the NSString* content and then varying several ways however to no avail! Any thoughts?
NSAppleEventDescriptor* returnDescriptor = NULL;
Perhaps the solution provided on Cocoa with Love might be useful?
Excerpt:
- (NSString *)findOrCreateDirectory:(NSSearchPathDirectory)searchPathDirectory
inDomain:(NSSearchPathDomainMask)domainMask
appendPathComponent:(NSString *)appendComponent
error:(NSError **)errorOut
{
// Search for the path
NSArray* paths = NSSearchPathForDirectoriesInDomains(
searchPathDirectory,
domainMask,
YES);
if ([paths count] == 0)
{
// *** creation and return of error object omitted for space
return nil;
}
// Normally only need the first path
NSString *resolvedPath = [paths objectAtIndex:0];
if (appendComponent)
{
resolvedPath = [resolvedPath
stringByAppendingPathComponent:appendComponent];
}
// Check if the path exists
BOOL exists;
BOOL isDirectory;
exists = [self
fileExistsAtPath:resolvedPath
isDirectory:&isDirectory];
if (!exists || !isDirectory)
{
if (exists)
{
// *** creation and return of error object omitted for space
return nil;
}
// Create the path if it doesn't exist
NSError *error;
BOOL success = [self
createDirectoryAtPath:resolvedPath
withIntermediateDirectories:YES
attributes:nil
error:&error];
if (!success)
{
if (errorOut)
{
*errorOut = error;
}
return nil;
}
}
if (errorOut)
{
*errorOut = nil;
}
return resolvedPath;
}
Maybe you can try using the NSFileManager to create the folder, then write the file into the folder.
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *applicationSupport = [[NSString stringWithString:#"~/Library/Application Support/'YOUR APP'] stringByExpandingTildeInPath];
if ([fileManager fileExistsAtPath:applicationSupport] == NO)
[fileManager createDirectoryAtPath:applicationSupport withIntermediateDirectories:YES attributes:nil error:nil];
NSString *fileName = [NSString stringWithFormat:#"%#/managersemail.txt", applicationSupport];
NSString* content = [NSString stringWithFormat:#"%#",[nameField stringValue]];
//save content to the documents directory
[content writeToFile:fileName
atomically:NO
encoding:NSStringEncodingConversionAllowLossy
error:nil];
So something like that should work. Feel free to leave comments to ask questions.
