NSFilenamesPboardType got deprecated on 10.14 and the suggestion is to use NSPasteboardTypeFileURL. This gives me filename as
file:///.file/id=6571367.12885025918
and NSWorkspace is unable to get UTI out of it.
How to get UTI from NSPasteboardTypeFileURL?
Old code:
- (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender
{
NSDragOperation sourceDragMask = [sender draggingSourceOperationMask];
NSDragOperation resultingDragMask = NSDragOperationNone;
NSPasteboard *pboard = [sender draggingPasteboard];
if ([[pboard types] containsObject:NSFilenamesPboardType]) {
NSArray <NSString *>*list = [pboard propertyListForType:NSFilenamesPboardType];
NSString *firstItem = [list objectAtIndexedSubscript:0];
NSError *error;
NSString *UTI = [[NSWorkspace sharedWorkspace] typeOfFile:firstItem error:&error];
if (!error) {
if ([[NSImage imageTypes] containsObject:UTI]) {
resultingDragMask = NSDragOperationCopy;
}
}
} else if ([[pboard types] containsObject:NSPasteboardTypeTIFF]) {
resultingDragMask = NSDragOperationCopy;
}
if (sourceDragMask & NSDragOperationCopy && resultingDragMask & NSDragOperationCopy) {
return NSDragOperationCopy;
}
return NSDragOperationNone;
}
With NSPasteboardTypeFileURL I get error which states file doesn't exist. Dragged from pasteboard:
Printing description of error:
Error Domain=NSCocoaErrorDomain Code=260 "The file “id=6571367.12885025918” couldn’t be opened because there is no such
file." UserInfo={NSURL=file:/.file/id=6571367.12885025918 --
file:///Users/xxx/Library/Containers/com.xxx.imageviewfix/Data/,
NSFilePath=/Users/xxx/Library/Containers/com.xxx.imageviewfix/Data/file:/.file/id=6571367.12885025918,
NSUnderlyingError=0x600000c70d80 {Error Domain=NSPOSIXErrorDomain
Code=2 "No such file or directory"}}
I am late to this question but I found this works:
NSArray<Class> *classes = #[[NSURL class]];
NSDictionary *options = #{};
NSArray<NSURL*> *files = [pboard readObjectsForClasses:classes options:options];
for (NSURL *url in files)
{
NSString *str = [url path];
// TODO: do something with str.
}
Unlike the other answer, dropping multiple files works with this approach.
Getting path of NSURL object gets the original filename. The only thing missing is the array of file paths which NSFilenamesPboardType used to give.
NSString *fileURL = [[NSURL URLFromPasteboard:pboard] path];
Updated code:
- (NSDragOperation)draggingEntered:(id <NSDraggingInfo>)sender
{
NSDragOperation sourceDragMask = [sender draggingSourceOperationMask];
NSDragOperation resultingDragMask = NSDragOperationNone;
NSPasteboard *pboard = [sender draggingPasteboard];
if ([[pboard types] containsObject:NSPasteboardTypeFileURL]) {
NSString *fileURL = [[NSURL URLFromPasteboard:pboard] path];
NSError *error;
NSString *UTI = [[NSWorkspace sharedWorkspace] typeOfFile:fileURL error:&error];
if (!error) {
if ([[NSImage imageTypes] containsObject:UTI]) {
resultingDragMask = NSDragOperationCopy;
}
}
} else if ([[pboard types] containsObject:NSPasteboardTypeTIFF]) {
resultingDragMask = NSDragOperationCopy;
}
if (sourceDragMask & NSDragOperationCopy && resultingDragMask & NSDragOperationCopy) {
return NSDragOperationCopy;
}
return NSDragOperationNone;
}
I know this question is posted many times but truly i didn't get any suggestion that can solve my problem. I wasted my two days on this problem but till now i didn't get any solutions. Please give your valuable guidance.

I'm trying to do a simple chat in iOS with Obj-C, and when I press the "send" button, I save the object into Parse and I retrieve all the messages.
When it succeeds, I retrieve all the messages so the last one (mine) should be retrieved as well, but the last one never gets called. What should I do?
This is my code:
NSMutableArray *messagesArray;
- (IBAction)sendButtonTapped:(id)sender {
self.sendButton.enabled = false;
self.textField.enabled = false;
PFObject *objectChat = [PFObject objectWithClassName: #"ChatClass"];
objectChat[#"text"] = self.textField.text;
[objectChat saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
self.sendButton.enabled = true;
self.textField.enabled = true;
if (succeeded) {
self.textField.text = #"";
[self retrieveMessages];
NSLog(#"success!");
} else {
NSLog(error.description);
}
}];
}
-(void) retrieveMessages {
NSDate *now = [NSDate date];
PFQuery *query = [PFQuery queryWithClassName:#"ChatClass"];
[query whereKey:#"createdAt" lessThanOrEqualTo:now];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (error == nil) {
messagesArray = [[NSMutableArray alloc] init];
for (int i = 0; i < [objects count]; i++) {
[messagesArray addObject:[[objects objectAtIndex:i] objectForKey:#"text"]];
}
runOnMainQueueWithoutDeadlocking(^{
[self.messageTableView reloadData];
});
}
}];
}
void runOnMainQueueWithoutDeadlocking(void (^block)(void))
{
if ([NSThread isMainThread])
{
block();
}
else
{
dispatch_async(dispatch_get_main_queue(), block);
}
}
Thank you very much in advance.
Regards.
Perhaps there's enough of a clock difference with the parse server that the time qualification misses the object just created. Removing that line should do the trick.
I have a working imagepicker that upon button click and hold gesture, allows the user to upload an image to the disk, and the user can change the image using the same gesture. The only issue is, however, I need this to be done twice on the same view (i.e. I have two imageviews, two buttons to change each of the imageviews, etc.), and I am stumped on how to get the second one to work. This is essentially what the view looks like:
Here is my current code:
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//
// Saving into Documents folder
//
NSString* path = [NSHomeDirectory() stringByAppendingString:#"/Documents/first.png"];
BOOL ok = [[NSFileManager defaultManager] createFileAtPath:path
contents:nil attributes:nil];
if (!ok) {
NSLog(#"Error creating file %#", path);
} else {
NSFileHandle* myFileHandle = [NSFileHandle fileHandleForWritingAtPath:path];
[myFileHandle writeData:UIImagePNGRepresentation(info [UIImagePickerControllerOriginalImage])];
[myFileHandle closeFile];
}
//
// Loading from documents
//
NSFileHandle* myFileHandle = [NSFileHandle fileHandleForReadingAtPath:path];
UIImage* loadedImage = [UIImage imageWithData:[myFileHandle readDataToEndOfFile]];
self.chosenImage = loadedImage;
[self.imageView setImage:self.chosenImage];
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void) imagePickerControllerDidCancel:(UIImagePickerController *)picker
{
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)onLongTile:(UILongPressGestureRecognizer *)gesture
{
switch ([gesture state]) {
case UIGestureRecognizerStateBegan:{
NSString *actionSheetTitle = #"Photo Options"; //Action Sheet Title
NSString *type = #"Upload Photo";
NSString *cancelTitle = #"Cancel";
UIActionSheet *actionSheet = [[UIActionSheet alloc]
initWithTitle:actionSheetTitle
delegate:self
cancelButtonTitle:cancelTitle
destructiveButtonTitle:nil
otherButtonTitles:type, nil];
[actionSheet showInView:self.view]; }
}
}
- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {
NSString *buttonTitle = [actionSheet buttonTitleAtIndex:buttonIndex];
if ([buttonTitle isEqualToString:#"Photo"]) {
self.imagePicker = [[UIImagePickerController alloc] init];
self.imagePicker.delegate = self;
[self.imagePicker setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
[self presentViewController:self.imagePicker animated:YES completion:nil];
}
}
Updated code with tags:
- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
if (self.imageViewOne.tag == 100)
{
//
// Saving into Documents folder
//
NSString* path = [NSHomeDirectory() stringByAppendingString:#"/Documents/one.png"];
BOOL ok = [[NSFileManager defaultManager] createFileAtPath:path
contents:nil attributes:nil];
if (!ok) {
NSLog(#"Error creating file %#", path);
} else {
NSFileHandle* myFileHandle = [NSFileHandle fileHandleForWritingAtPath:path];
[myFileHandle writeData:UIImagePNGRepresentation(info [UIImagePickerControllerOriginalImage])];
[myFileHandle closeFile];
}
//
// Loading from documents
//
NSFileHandle* myFileHandle = [NSFileHandle fileHandleForReadingAtPath:path];
UIImage* loadedImage = [UIImage imageWithData:[myFileHandle readDataToEndOfFile]];
self.chosenImageOne = loadedImage;
[self.imageViewOne setImage:self.chosenImageOne];
[self dismissViewControllerAnimated:YES completion:nil];
}
if (self.imageViewTwo.tag == 200)
{
//
// Saving into Documents folder
//
NSString* path = [NSHomeDirectory() stringByAppendingString:#"/Documents/two.png"];
BOOL ok = [[NSFileManager defaultManager] createFileAtPath:path
contents:nil attributes:nil];
if (!ok) {
NSLog(#"Error creating file %#", path);
} else {
NSFileHandle* myFileHandle = [NSFileHandle fileHandleForWritingAtPath:path];
[myFileHandle writeData:UIImagePNGRepresentation(info [UIImagePickerControllerOriginalImage])];
[myFileHandle closeFile];
}
//
// Loading from documents
//
NSFileHandle* myFileHandle = [NSFileHandle fileHandleForReadingAtPath:path];
UIImage* loadedImage = [UIImage imageWithData:[myFileHandle readDataToEndOfFile]];
self.chosenImageTwo = loadedImage;
[self.imageViewTwo setImage:self.chosenImageTwo];
[self dismissViewControllerAnimated:YES completion:nil];
}
}
From what I understood of the question, set tags to your UIImageView and change is accordingly. something like:
[self.imageViewOne setTag:100];
[self.imageViewTne setTag:200];
And then in your delegates you can check the tag value and do the needful:
if ( imageView.tag == 100)
{
// Code for first imageView
}
The purpose when I select a row from a tableView, having data loaded from sqlite, to be capable of changing the value of a certain field.
Manipulating through two views, the first one loads the entire database into a mutable array, and when I press a certain field, I go to another view. In this second view, I have a button. How to obtain the result of when pressing this button the field in the database will change value.

First you have to take the values of selected row;
This is in your TABLEVIEWCONTROLLER
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath*)indexPath {
if(listObject.count!=0){
//you will get the object from the list
ObjectType *selectedObject=(ObjectType*)[listObject objectAtIndex:indexPath.row];
//you can call your view controller (in my example init with nib)
yourDetailViewController = [[YourDetailViewController alloc] initWithNibName:#"YourDetailViewControllerNib" bundle:nil];
//you can set your selected object in order to use it on your detail view controller
yourDetailViewController.objectSelected = selectedObject;
[self.navigationController yourDetailViewController animated:YES];
}
}
And this is in your DETAILVIEWCONTROLLER;
-(void)objectUpdate:(Object*)selectedObject withDBPath:(NSString *)dbPath{
NSError *errMsg;
if (sqlite3_open([dbPath UTF8String], &database) == SQLITE_OK) {
const char *sql_stmt = [#"CREATE TABLE IF NOT EXISTS iosobjecttable (yourcolumns INTEGER PRIMARY KEY NOT NULL , youranothercolumn VARCHAR)" cStringUsingEncoding:NSUTF8StringEncoding];
if (sqlite3_exec(database, sql_stmt, NULL, NULL, (__bridge void*)errMsg) == SQLITE_OK)
{
// SQL statement execution succeeded
}
if(updateStmt == nil) {
NSString *querySQL = [NSString stringWithFormat:
#"update iosobject set youranothercolumn=%# where p_event_id=%#", object.changedcomlumn,object.objectid];
const char *query_sql = [querySQL UTF8String];
if(sqlite3_prepare_v2(database, query_sql, -1, &updateStmt, NULL) != SQLITE_OK){
NSAssert1(0, #"Error while creating update statement. '%s'", sqlite3_errmsg(database));
//NSLog(#"%#",errMsg);
}
}
#try {
if(SQLITE_DONE != sqlite3_step(updateStmt)){
NSAssert1(0, #"Error while updating data. '%s'", sqlite3_errmsg(database));
//NSLog(#"%#",errMsg);
}
else{
//NSLog(#"updatingupdatingedelementt %#",tEvent.eventid);
}
sqlite3_reset(updateStmt);
}
#catch (NSException* ex) {
//NSLog(#"Error while updating data. '%s'", sqlite3_errmsg(database));
}
}
}
and how you call this function is like this;
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
NSString *dbPath=[appDelegate getDBPath];
[self objectUpdate:objectUpdate withDBPath:dbPath];
And in app delegate you have to write getDBPath in app delegate;
- (NSString *) getDBPath {
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
NSString *documentsDir = [paths objectAtIndex:0];
return [documentsDir stringByAppendingPathComponent:#"yourdbname.sqlite"];
}
