I have made code to upload image from document directory to Sample Album of Dropbox.
But it dosen't work as i want.
My code:
-(NSString *)getDocumentPath{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *path = [[paths objectAtIndex:0]stringByAppendingPathComponent:#"image1.jpg"];
NSLog(#"path:%#",path);
return path;
}
-(IBAction)uplaodingPhotos:(id)sender
{
NSString *path = [self getDocumentPath];
[[self restClient] uploadFile:#"splash.jpg" toPath:#"/Photos/Sample Album"
withParentRev:nil fromPath:path];
}
In this code i want to add image image1 from document directory to Sample Album in Dropbox.
But it dosen't copy image.Now what i have to do?
Please Help.
Thank in advance.
First you need to make sure you are connected with dropbox session and your rest client is not nill.

my app is creating a CSV file out of a db. I want to browse and open the file to test. How do I access the iphone simulator's storage ?
All data of the Simulator is stored as local files on your Mac.
The path for the user data of iOS apps in the Simulator is:
~/Library/Application Support/iPhone Simulator/[OS version]/Applications/[appGUID]/
You'll want to print out the location of where you store your file when you run the app in the simulator.
You can use this code to get the location of the Library/Cache folder here:
-(NSString *) mediaPathForFileName:(NSString *) fileName
{
NSArray *directoryPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cachesDirectory = [directoryPaths objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#", cachesDirectory, fileName];
return filePath;
}
Pass in a random file name like "test.txt":
// somewhere in your viewDidLoad method
[self mediaPathForFileName:#"test.txt"];
This will print out the path to your app Library/Cache folder.
you need get the path of that file by using NSLog and then user Shift+Cmd+G to go to that path.
pritn this path
NSArray *directoryPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
I want to load a webpage when user connected to network and store it offline(including with images/resources). If the user not connected to any network then i should load the previously stored webpage. I have tried NSData dataWithContentsOfURL:(NSURL *)url and NSString stringWithContentsOfURL but these stores only html content not the resources.
Thanks in advance.
You can do that with ASIHttpRequest. If you do not want to to use that project (it is no longer active) you can look into the code and what it does. Look at "how to cache a whole web page with images in iOS" for more info as well.
I think the simple solution is this - "Safari Client-Side Storage and Offline Applications Programming Guide", https://developer.apple.com/library/archive/documentation/iPhone/Conceptual/SafariJSDatabaseGuide/Introduction/Introduction.html
Only if you are making an app with HTML5 and webview, didn't test this method yet so far, so it might work.
Write this data into file using:
-(void)writeDataToFile:(NSString*)filename
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
if(filename==nil)
{
DLog(#"FILE NAME IS NIL");
return;
}
// the path to write file
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat: #"%#",filename]];
/*NSData *writeData;
writeData=[NSKeyedArchiver archivedDataWithRootObject:pArray]; */
NSFileManager *fm=[NSFileManager defaultManager];
if(!filePath)
{
//DLog(#"File %# doesn't exist, so we create it", filePath);
[fm createFileAtPath:filePath contents:self.mRespData attributes:nil];
}
else
{
//DLog(#"file exists");
[self.mRespData writeToFile:filePath atomically:YES];
}
NSMutableData *resData = [[NSMutableData alloc] init];
self.mRespData=resData;
[resData release];
}
and load it next time.
I don't know if there is one-line-solution like myWebView.cache4Offline = YES; , but I fear as long as you don't have access to the website's code (i.e. if you want to make any website available offline inside your app), you have to program this on your own. Thinking about it, it doesn't seem so difficult:
Scan the html string for image urls (and everything else you need)
Download those resources from the internet using NSData dataWithContentsOfURL (maybe a little annoying, because of relative/absolute URLs)
Save data to file with NSData writeToFile:options:error:
Replace URL in HTML with filePath from 3. (OR, better use a convention for converting their URLs in your file-URLs)
Hope it helps
I have a simple (I think) question :
I got an iPhone. He create a plist file and he save it. I want to upload this file on a server.
Then, with 3 others iPhone, I will download this plist file and decrypt the informations.
My question is : How can I upload this plist file into a server !!
I don't have any FTP server or others ... Can I use instead Dropbox by exemple ?
Or is an other way to communicate between iPhone (private - not for AppStore) ?
Thanks very much for your answers !
Yes, you can use Dropbox API to upload a plist on the Dropbox user's folder.
Check first this link to setup your project
You can use these snippets (from this page):
NSString *localPath = [[NSBundle mainBundle] pathForResource:#"Info" ofType:#"plist"];
NSString *filename = #"Info.plist";
NSString *destDir = #"/";
[[self restClient] uploadFile:filename toPath:destDir
withParentRev:nil fromPath:localPath];
then implement the callbacks
- (void)restClient:(DBRestClient*)client uploadedFile:(NSString*)destPath
from:(NSString*)srcPath metadata:(DBMetadata*)metadata {
NSLog(#"File uploaded successfully to path: %#", metadata.path);
}
- (void)restClient:(DBRestClient*)client uploadFileFailedWithError:(NSError*)error {
NSLog(#"File upload failed with error - %#", error);
}
EDIT:
(if you want, you can load the plist from the Documents folder of your app. remember that the mainBundle is read-only so you can't modify the plist that resides in the main bundle, you can only read it)..like this:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);
NSString *plistFilePath = [[paths objectAtIndex:0]stringByAppendingPathComponent:#"info.plist"];
NSDictionary *plistFile = [[NSMutableDictionary alloc] initWithContentsOfFile:plistFilePath];
I use NSKeyedArchiver to archive data in my iPhone app into a .data. Long story, short, I lost all my data. I use "iPhone back up extractor" and it works great. I found a .data file for my app.
To be clear, I found a .data file and I would to open and see what the contents look like. I understand no software (Ex: notepad) might be able to read that file and I may have to use Xcode. If you know of any way, Xcode/notepad/someProgram, please let me know.
This is the code that I implement when I build the app:
- (NSString *)locPath {
return pathInDocumentDirectory(#"tableArray.data");
}
- (void)archieve{
// Get the path to the document directory
NSString *path = [self locPath];
// grab the array
NSMutableArray *tableArray = [someViewController tableArray];
// archive the array to file
[NSKeyedArchiver archiveRootObject:tableArray toFile:path];
}
This code is called during applicationWillTerminate, applicationDidEnterBackground, etc...
The data is restored/called upon in the didFinishLaunchingWithOptions like this:
// Get the path to the document directory
NSString *path = [self locPath];
// Unarchive .data into an array
NSMutableArray *tableArray = [NSKeyedUnarchiver unarchiveObjectWithFile:path];
Any help is appreciated! Thanks!!!
PS: Link for iPhone back up extractor is http://supercrazyawesome.com/
The easiest way I found is to get the document directory using this code:
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *dir = [paths objectAtIndex:0];
NSLog(#"Directory: %#", dir);
In there, the Documents dir will contain the .data file
I am simply creating a student management system in iPhone.
There I need to store student's small images,
Which should be appear in tableView,
Ok, I know how to work with tableView...
how to work with database...
But question is
Where to store images
how can we obtain the path of stored images..
Do i have to store entire images to database...
Or
i have to store relative path of image to database...
What is suggested by You masters?
Thanks in advance for helping me.
You can create image files on the file system of the device in the Document directory. Use something like this:
// Generate a unique user filename
NSString *imageFilename = [NSString stringWithFormat:#"student_image_%#", uniqueIdentifier];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *path = [NSString stringWithFormat:#"%#/%#", [paths objectAtIndex:0], imageFilename];
NSData *storage = [image UIImagePNGRepresentation]; // or UIImageJPEGRepresentation
[storage writeToFile:path atomically:NO];
Best Regards,
