I need to call this method manually but I'm confused how to format the completionHandler. I don't understand what I'm reading. Can anyone give me an example of how to define the completionHandler or point me to some documentation?
[self saveToURL:[self fileURL] ofType:@"myDocType" forSaveOperation:NSAutosaveInPlaceOperation completionHandler:^(I'm confused!!!)];
This is the method definition
- (void)saveToURL:(NSURL *)url ofType:(NSString *)typeName forSaveOperation:(NSSaveOperationType)saveOperation completionHandler:(void (^)(NSError *errorOrNil))completionHandler
I've used blocks before like below but I don't understand the syntax above and I couldn't find an example on the internet or the documentation. Any help would be appreciated.
[openPanel beginSheetModalForWindow:[NSApp keyWindow] completionHandler:^(NSInteger theResult) {
if (theResult) {
// some code here
}
