Doc based, QTKit app. When saving, the new filename updates in the active window titleBar. I would also like to display the newly saved filename string in a textField, somewhere else on the opened doc. The code successfully saves the new doc. However the lastPathComponent string doesn't update. Please advise?
thanks,
Paul

Since "filename" is apparently valid (because things are working and your window title updates), have you checked to make sure "textField" is actually connected in your XIB?

Ok, yes I know now that you can not use hardcoded paths with sandbox. Up to this point I have not delt with sandbox, so I never encountered it.
I have a Coredata App (Mac OSx) and I used the default save code and the default path location (user/...../applicationsupport/... This, of coarse, is not acceptable in the sandbox.
Without requiring the user to manually open the data file each time the program is launched, is there another way to deal with this?
I would appreciate any input/suggestions.
Thanks You
Sandbox doesn't mean there isn't any access to files and folders without user selection. As it said in App Sandbox in Depth article there's container directory you still having access to.
For taking a path to your Application Support-directory you should use the same code whenever you use Sandboxing or not.

i have this code working on IOS7, its check if an image exist in device and if not, it download locally.
Now on IOS8 doesnt save nothing, could someone help me?
//folder where save
NSString *ImagesPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"Documents"]];
// check if image exist
NSString* foofile = [ImagesPath stringByAppendingPathComponent:nombreImagenLocal];
BOOL fileExists = [[NSFileManager defaultManager] fileExistsAtPath:foofile];
// check if image exist locally
if (!fileExists){
NSData *data = [NSData dataWithContentsOfURL:[NSURL URLWithString:rutaCompletaLogo]];
//if not, i save it
if (data) {
// url where is saved
NSString *cachedImagePath = [ImagesPath stringByAppendingPathComponent:nombreImagenLocal];
if ([data writeToFile:cachedImagePath atomically:YES]) {
NSLog(#"Downloaded file saved to: %#", cachedImagePath);
}// end
The path to 'Documents' folder has changed from iOS8. Check the Apple tech note
Please, make sure you don't use hardcoded values. Use the methods provided by the API:
NSString *resourcePath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
OR (as stated in the previous link)
// Returns the URL to the application's Documents directory.
- (NSURL *)applicationDocumentsDirectory{
return [[[NSFileManager defaultManager] URLsForDirectory:NSDocumentDirectory inDomains:NSUserDomainMask] lastObject];
}
Hope this helps!
I'm using a WebView in edit mode. I have implemented this method from WebUIDelegate Procotol:
- (void)webView:(WebView *)sender willPerformDragDestinationAction:(WebDragDestinationAction)action forDraggingInfo:(id < NSDraggingInfo >)draggingInfo
and use it to catch the drops of elements on my WebView. When I detect a file being dragged from outside my app, and containing a picture, I build in this method the img DOM element and add it to my document.
This works fine, but as the method's name implies, I am only informed that the drag will happen, and I have no control over it.
As the Finder always does file drag operation, what normally happens when dropping a file on a WebView in editing mode is the webview displays the path of the file.
I end up having the file path string added to my webview, and the image too, but I would like to prevent the text from being added.
Is there any way to configure this without subclassing webview?
I tried it and while it works, it breaks plenty of other things like caret moving for the drop and such.
Answering this myself for a change!
- (BOOL)performDragOperation:(id <NSDraggingInfo>)sender
{
if ([sender draggingSource] == nil)
{
NSPasteboard *pboard = [sender draggingPasteboard];
if ( [[pboard types] containsObject:NSFilenamesPboardType] ) {
NSURL* fileURL;
fileURL=[NSURL URLFromPasteboard: [sender draggingPasteboard]];
NSArray *dragTypes = [NSArray arrayWithObject:NSFileContentsPboardType];
[[sender draggingPasteboard] declareTypes:dragTypes owner:nil];
NSImage *content = [[NSImage alloc] initWithContentsOfURL:fileURL];
[[sender draggingPasteboard] setData:[content TIFFRepresentation] forType:NSPasteboardTypeTIFF];
}
}
return [super performDragOperation:sender];
}
Actually, what I did was indeed to subclass the WebView and intercept the performDragOperation to change the content of the dragging pasteboard, if the dragging source is outside of my app and doesn't contain already an image but only a filename.
I ran into the same issue.
What I found is that subclassing the view is the best place for this to insert the image data into the pasteboard. Here is how I am doing it for multiple files:
- (BOOL) performDragOperation:(id<NSDraggingInfo>)sender {
if ( [sender draggingSource] == nil ) {
NSPasteboard *pboard = [sender draggingPasteboard];
NSArray *classes = #[ [NSURL class] ];
NSDictionary *options = #{ NSPasteboardURLReadingFileURLsOnlyKey: [NSNumber numberWithBool:YES],
NSPasteboardURLReadingContentsConformToTypesKey: [NSImage imageTypes] };
NSArray *fileURLs = [pboard readObjectsForClasses:classes options:options];
if ( fileURLs ) {
NSMutableArray *images = [NSMutableArray arrayWithCapacity:[fileURLs count]];
for ( NSURL *fileURL in fileURLs )
[images addObject:[[NSImage alloc] initWithContentsOfURL:fileURL]];
[pboard declareTypes:[NSImage imageTypes] owner:nil];
[pboard clearContents]; [pboard writeObjects:images];
}
} return [super performDragOperation:sender];
}
What I noticed is the following sequence:
1. WebView captures drag operation.
2. Internal WebCore created document fragment
3. Node is inserted into a DOMRange
4. Editing Delegate is called
5. Lastly UI Delegate is called where it is too late to do anything
Also, I suggest setting the following via the UI Delegate:
- (NSUInteger) webView:(WebView *)webView dragDestinationActionMaskForDraggingInfo:(id <NSDraggingInfo>)draggingInfo {
return WebDragDestinationActionEdit;
}
Ok, now the ISSUE I am running into and I really hope you might have an answer for me. When I select one file no problem. When I select multiple files, I get them and add all of them into the pasteboard properly. Even when I get to (5) for the UIDelegate and inspect the draggingPasteboard for its count I get what is expected. But unfortunately the document fragment is only being created once and likewise only one node gets inserted.
Any ideas how to get multiple fragments to be created so that they can all be inserted?
Thank you in advance.
Fixed version for the previous replies, this code works for multiple images dragged in the web view.
- (BOOL)performDragOperation:(id<NSDraggingInfo>)sender
{
if ( [sender draggingSource] == nil )
{
NSPasteboard *pboard = [sender draggingPasteboard];
NSArray *classes = #[ [NSURL class] ];
NSDictionary *options = #{ NSPasteboardURLReadingFileURLsOnlyKey: [NSNumber numberWithBool:YES],
NSPasteboardURLReadingContentsConformToTypesKey: [NSImage imageTypes] };
NSArray *fileURLs = [pboard readObjectsForClasses:classes options:options];
if(fileURLs)
{
NSArray* filenames = [pboard propertyListForType: NSFilenamesPboardType];
NSMutableString* html = [NSMutableString string];
for(NSString* filename in filenames) {
[html appendFormat: #"<img src=\"%#\"/>", [[[NSURL alloc] initFileURLWithPath: filename] absoluteString]];
}
[pboard declareTypes: [NSArray arrayWithObject: NSHTMLPboardType] owner: self];
[pboard setString: html forType: NSHTMLPboardType];
}
} return [super performDragOperation:sender];
}
I would like to add an NSTextView object to my app and add an action that opens a .txt file located in the app bundle in the textView. Also - I would like to have the option to edit and save the edited doc without renaming it. So standard save, not save as.
What's the best way to handle this?
Use NSString to load the file and put it in your text view:
NSTextView *textView; //your NSTextView object
NSError *err = nil;
NSString *path = [[NSBundle mainBundle] pathForResource:#"EditableFile" ofType:#"txt"];
NSString *contents = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:&err];
if(!contents) {
//handle error
}
[textView setString:contents];
Saving is just the opposite. Get the string and write it to the file:
NSTextView *textView; //your NSTextView object
NSError *err = nil;
NSString *path = [[NSBundle mainBundle] pathForResource:#"EditableFile" ofType:#"txt"];
NSString *contents = [textView string];
if(![contents writeToFile:path atomically:YES encoding:NSUTF8StringEncoding error:&err]) {
//handle error
}
I have cocoa application running on OS X. I have used NSLog for debugging purpose. Now I want to redirect the log statements to file instead of console.
I have used this method but it results logging in Console as well as in file.
- (BOOL)redirectNSLog
{
// Create log file
[#"" writeToFile:#"/NSLog.txt" atomically:YES encoding:NSUTF8StringEncoding error:nil];
id fileHandle = [NSFileHandle fileHandleForWritingAtPath:#"/NSLog.txt"];
if (!fileHandle) return NSLog(#"Opening log failed"), NO;
[fileHandle retain];
// Redirect stderr
int err = dup2([fileHandle fileDescriptor], STDERR_FILENO);
if (!err) return NSLog(#"Couldn't redirect stderr"), NO;
return YES;
}
Is it possible to not have log statement in console but only in file ??
Step 1: Include following function in AppDelegate:
- (void) redirectConsoleLogToDocumentFolder
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *logPath = [documentsDirectory stringByAppendingPathComponent:#"console.log"];
freopen([logPath fileSystemRepresentation],"a+",stderr);
}
Step 2: Call this function at the start of function applicationDidFinishLaunchingWithOptions...
Thats it, Every NSLog() will now get redirected to this console.log file, which you can find in the documents directory.
Recently i have faced similar requirement and this is how i have done it.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// Override point for customization after application launch.
[self redirectConsoleLogToDocumentFolder];
return YES;
}
- (void) redirectConsoleLogToDocumentFolder
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,
NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *logPath = [documentsDirectory stringByAppendingPathComponent:#"console.txt"];
freopen([logPath fileSystemRepresentation],"a+",stderr);
}
And Now if you want to this console to user
-(void)displayLog{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths firstObject];
NSString *logPath = [documentsDirectory stringByAppendingPathComponent:#"console.txt"];
NSError *err = nil;
NSString *fileContents = [NSString stringWithContentsOfFile:logPath
encoding:NSUTF8StringEncoding
error:&err];
if (fileContents == nil) {
NSLog(#"Error reading %#: %#", logPath, err);
} else {
self.textView.text = fileContents;
}
}
You may be interested in CocoaLumberjack. It is a very flexible logging framework for both Mac OS X and iOS. One logging statement can be sent not only to the console but to a file simultaneously. Plus it is actually faster then NSLog. I use it in a project that has common code for both OS X and iOS.
NSLog is made to log into the console. You need to define your own function MyLog or whatever, and replace all occurrences of NSLog into MyLog.
