Obj-C: application:openFiles: (multiple files dropped) not receiving all files. Bug? - objective-c

Question

Closest one I found is: https://stackoverflow.com/questions/4778932/cocoa-app-not-receiving-all-dropped-files-in-applicationopenfiles
But it hasn't been answered.
My Problem is this,
So let's say I am dropping 4 files on my dock application:
test.xls
test.rtf
test.jpg
test.pdf
If I go debug my program it shows this:
Debug log
As you can see the .jpg file is not in there.
This also happens for: .py, other image types, .txt files
I have found out that if I drop files only from that group (.py .jpg .txt) then it recognizes all of them.
My Info.plist looks like this:
<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEplistPUBLIC"-//Apple//DTDPLIST1.0//EN""http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plistversion="1.0">
<dict>
<key>CFBundleDevelopmentRegion</key>
<string>en</string>
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeName</key>
<string>AllFiles</string>
<key>CFBundleTypeIconFile</key>
<string>application.icns</string>
<key>CFBundleTypeRole</key>
<string>Viewer</string>
<key>LSHandlerRank</key>
<string>Alternate</string>
<key>LSItemContentTypes</key>
<array>
<string>public.item</string>
</array>
</dict>
</array>
I don't know where the error is in here, maybe it's a bug? Or did I configure my info.plist wrong?
I hope someone can help me and thank you all in advance!

Answer 1

I encountered the same problem and here is how I solved it:
#property (strong) NSMutableArray *openFilesList;
#property (strong) NSTimer *openFilesTimer;
...
#synthesize openFilesList;
#synthesize openFilesTimer;
...
-(void)init {
openFilesList = [[NSMutableArray alloc] init];
openFilesTimer = nil;
}
-(void)application:(NSApplication *)sender openFiles:(NSArray *)filenames {
if (openFilesTimer) {
[openFilesTimer invalidate];
}
[openFilesList addObjectsFromArray:filenames];
openFilesTimer = [NSTimer scheduledTimerWithTimeInterval:0.2f
target:self
selector:#selector(processOpenFiles)
userInfo:nil
repeats:NO];
}
-(void)processOpenFiles {
NSArray *filenames = [openFilesList copy];
openFilesTimer = nil;
[openFilesList removeAllObjects];
// Do your processing with filenames
}

Answer 2

set in info.plist like this
<key>CFBundleDocumentTypes</key>
<array>
<dict>
<key>CFBundleTypeExtensions</key>
<array>
<string>*</string>
</array>
<key>CFBundleTypeName</key>
<string>Files</string>
<key>CFBundleTypeRole</key>
<string>Editor</string>
<key>LSItemContentTypes</key>
<array>
<string>public.data</string>
</array>
</dict>
</array>
and use this method in AppDelegate.m
-(void)application:(NSApplication *)sender openFiles:(NSArray *)fileList{
// use fileList array
}
-(BOOL)application:(NSApplication *)sender openFile:(NSString *)filename{
return YES;
}
