Thanks for the input everyone.
For those curious, this is the final code:
- (BOOL)application:(NSApplication *)theApplication openFile:(NSString
*)filename
{
NSError *err = nil;
NSString *utiFile = [[NSWorkspace sharedWorkspace] typeOfFile:filename
error:&err];
if (err) {
NSRunAlertPanel(NSLocalizedString(@"Error opening file",nil),
[NSString stringWithFormat:NSLocalizedString(@"Unable to open %@: %@", nil),
[filename lastPathComponent], [err localizedFailureReason]], nil, nil, nil);
return NO;
}
NSArray *handlers = [NSArray arrayWithObjects:[PcsxrPluginHandler
class], [PcsxrMemCardHandler class], [PcsxrFreezeStateHandler class],
[PcsxrDiscHandler class], nil];
BOOL isHandled = NO;
for (Class fileHandler in handlers) {
NSObject<PcsxrFileHandle> *hand = [[fileHandler alloc] init];
BOOL canHandle = NO;
for (NSString *uti in [fileHandler supportedUTIs]) {
if ([[NSWorkspace sharedWorkspace] type:utiFile
conformsToType:uti]) {
canHandle = YES;
}
}
if (canHandle) {
isHandled = [hand handleFile:HandleBinCue(filename)];
}
[hand release];
}
return isHandled;
}
