I call NSOpenPanel with this code:
NSOpenPanel *panel = [NSOpenPanel openPanel];
NSArray * fileTypes = [NSArray arrayWithObjects:#"png",#"jpg",#"jpeg",#"gif",#"pdf",nil];
[panel setAllowedFileTypes:fileTypes];
[panel setCanChooseFiles:YES];
[panel setCanChooseDirectories:NO];
[panel setAllowsMultipleSelection:YES]; // yes if more than one dir is allowed
[panel beginSheetModalForWindow:self.view.window completionHandler: ^(NSInteger result) {
if (result == NSFileHandlingPanelOKButton) {
for (NSURL *fileURL in [panel URLs]) {
}
return;
} else {
[self dismissController:self];
}
}];
The error appears first when I choose a file.
The app does not crash and I do get the filenames.
Hope someone can help :)

After upgrading to Yosemite, I'm getting a very weird crash when I run a NSSavePanel in my app. For example, I select openDocument: and it crashes. Or I open the panel to browse files and it crashes.
An uncaught exception was raised

This is a bug with the extension class you are using. NSArray+CocoaDevUsersAdditions firstObject method is implemented wrong. The relevant parts of the crash log you posted are these three lines:
1 libobjc.A.dylib 0x973bea2a objc_exception_throw + 276
2 CoreFoundation 0x97b1cf8c -[__NSArrayI objectAtIndex:] + 204
3 MyApp 0x0013c830 -[NSArray(CocoaDevUsersAdditions) firstObject] + 41
The index 0 beyond bounds for empty array error happens when you try to access the index 0 of an array that contains no objects.
I found some code that I think matches the NSArray+CocoaDevUsersAdditions class at this URL
-(id)firstObject
{
return [self objectAtIndex:0];
}
The above code is wrong. It should check the count of objects first. Correct code should look like this:
-(id)firstObject
{
id result = nil;
if (self.count > 0) {
result = [self objectAtIndex:0];
}
return result;
}
So the problem is the NSArray extension you are using is implemented wrong.
Best solution: Remove your NSArray+CocoaDevUsersAdditions category and use the public firstObject method on NSArray
I'm trying to write a piece of code that would "modernize" a video file. This is the code :
NSOpenPanel *openPanel = [[NSOpenPanel alloc] init];
[openPanel setCanChooseFiles:NO];
[openPanel setCanChooseDirectories:YES];
if([openPanel runModal] == NSCancelButton)
return;
NSMutableString *destination = [[[openPanel URL] absoluteString] mutableCopy];
[destination appendString:#"/"];
[destination appendString:[self fileName:[url absoluteString] withExtention:NO]];
[destination appendString:#".m4v"];
QTMovieModernizer *modernizer = [[QTMovieModernizer alloc] initWithSourceURL:url destinationURL:[NSURL URLWithString:destination]];
[modernizer modernizeWithCompletionHandler:^{NSLog(#"Modernization complete to file %# - error : %#",[modernizer destinationURL],[modernizer error]);}];
The problem is that I get an NSInvalidArgumentException. I've checked the source and destination url carefully and they seem to be ok. The error seems to happen at the initialization the QTMovieModernizer instance. What can be going wrong here?
Error details :

EDIT :
I found out that -fileName:withExtension: returns a string by replacing %20 by spaces. After handling this, the exception at the initsilizing is gone but instead, I have the following error when converting the file :
<<<< QTMovieModernizer >>>> FigFormatUtilsCreateFormatReader: Error -12848 from FigFormatReaderCreateForStream
<<<< QTMovieModernizer >>>> formatReaderForSourceURL: Error in FormatReaderForSourceURL: -12848
I have the following code to retrieve the currentTrack's artwork (using iTunes.h):
iTunesArtwork *iTunesArtwork = [[iTunes.currentTrack artworks] objectAtIndex:0];
NSImage *artwork = iTunesArtwork.data;
if (artwork != nil){
[_musicImageView setImage:artwork];
}
It works for most of the tracks but sometimes it gives me this error (even when the track has an image):
NSImageCell's object value must be an NSImage.

Any ideas on what's going on?
make sure it is an image -- not just check if its not nil, thats not enough. the type in an h file must not be the type the object really has. It is more like... it SHOULD be an image :D
if([artwork isKindOfClass:[NSImage class]]) {
....
from the comments.
That didnt always work. ell. no more crashes but some images didnt show. we used the rawData as fallback:
//kind of like this
if(![artwork isKindOfClass:[NSImage class]]) {
artwork = [[NSImage alloc] initWithData:tunesArtwork.rawData];
}
if([artwork isKindOfClass:[NSImage class]]) {
...
}
Here is my code:
.h
NSMutableString *buffer, *tmpBuffer;
int status; // 0=waiting for <DMX>, 1=recording
.m
- (void)applicationDidFinishLaunching:(NSNotification *)aNotification
{
buffer = [[NSMutableString alloc] init];
tmpBuffer = [[NSMutableString alloc] init];
status = 0;
}
- (void) receivedData:(NSString *)data {
// status=0 means we are still looking for start tag
if(status == 0) {
// add new data to last examined chunk (if any)
[tmpBuffer appendString:data];
// try to locate the open tag inside the tmpBuffer
NSRange range = [tmpBuffer rangeOfString:#"<DMX>" options:NSCaseInsensitiveSearch];
// if found, store the portion after the start tag into buffer
if(range.location != NSNotFound) {
range.length = [tmpBuffer length] - range.location + 5; // 5 is length of start tag...
[buffer setString:[tmpBuffer substringWithRange:range]];
status = 1; // set status to 1 so we know recording started
} else {
// store last examined chunk
[tmpBuffer setString:data];
}
} else {
[buffer appendString:data];
NSRange range = [buffer rangeOfString:#"</DMX>" options:NSCaseInsensitiveSearch];
if(range.location != NSNotFound) {
range.length = [buffer length] - range.location;

libc++abi.dylib: terminate called throwing an exception
(lldb)
It's happening where [self fullDMXReceived:buffer]; is called because when I remove it, it doesn't crash.
What's happening here? Can anyone decode this error?
FYI, I'm calling receivedData from another class like this: AppDelegate *theAppDelegate = [[AppDelegate alloc] init]; [theAppDelegate receivedData:string]; Could this be a problem?
When I run AppDelegate *theAppDelegate = (AppDelegate *)[[NSApplication sharedApplication] delegate];
I get this error message:

libc++abi.dylib: terminate called throwing an exception
(lldb)
In comments, you say:
AppDelegate *theAppDelegate = [[AppDelegate alloc] init];
[theAppDelegate receivedData:string];
That creates a new AppDelegate object, which means the applicationDidFinishLaunching method isn't being called (it was already called in the first AppDelegate instance). Use the original one instead.
AppDelegate *theAppDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
I want to store the FTP Password in a Keychain rather than in the NSUserDefaults. So I used a wrapper called EMKeyChain to store the problem. The problem being is that it won't load the password when the Preference Window is loaded:
Note: FTPPassword is a IBOutlet for NSTextField in PreferenceController.h
-(void)windowDidLoad
{
//Check Login Keychain
[self loadlogin];
//Set FTP Password Delegate to PreferenceController
[FTPPassword setDelegate:self];
//Load Password
EMGenericKeychainItem *keychainItem = [EMGenericKeychainItem genericKeychainItemForService:#"MelScrobbleX" withUsername: #"ftp"];
if (keychainItem.password != nil) {
[FTPPassword setValue:keychainItem.password];
}
Resulting in this big nasty error:

The program creates a new keychain item every time the password changes even though the keychain item exists already. (This selector is for FTPPassword)
- (void)controlTextDidEndEditing:(NSNotification *)aNotification {
EMGenericKeychainItem *keychainItem = [EMGenericKeychainItem genericKeychainItemForService:#"MelScrobbleX" withUsername: #"ftp"];
if (keychainItem.password == nil) {
//Create Keychain
NSLog(#"Creating Keychain");
[EMGenericKeychainItem addGenericKeychainItemForService:#"MelScrobbleX" withUsername:#"ftp" password:[FTPPassword stringValue]];
}
else if (keychainItem.password != [FTPPassword stringValue]){
//Save Password
NSLog(#"Saving Password");
keychainItem.password = [FTPPassword stringValue];
}
else if ([[FTPPassword stringValue] length] == 0){
//Blank Password. Remove Keychain Item
NSLog(#"Deleting Password");
[keychainItem removeFromKeychain];
}
}
Notes: The required frameworks are already linked (Security.framework and Carbon.framework) and this error happens with GC on and off. Also, I'm using the Mac OS X 10.5 SDK.
Your error says
-[NSSecureTextField setValue:]: unrecognized selector sent to instance 0x10c4be0
You should look up the reference, see NSSecureTextField. By traversing the class hierarchy, you eventually find there's no such method as setValue:.
I guess you wanted to do
[FTPPassword setStringValue:keychainItem.password];
instead of
[FTPPassword setValue:keychainItem.password];
I would've thought that the compiler should have warned against using setValue: because there's no such method in NSControl,
but I found this informal protocol defining setValue: as a category method of NSObject. Alas...
