As already stated in a previous answer, the notification type needs to be set to alert for the action button to be shown. If you want to set the default notification style of your app to alert, you need to define the key NSUserNotificationAlertStyle in info.plist with the value alert. See Apple’s info.plist keys reference … Read more
Improving on that CocoaRocket solution: The following saves having to subclass NSTextField and remembering to use the subclass throughout your application; it will also enable copy, paste and friends for other responders that handle them, eg. NSTextView. Put this in a subclass of NSApplication and alter the principal class in your Info.plist accordingly. – (void) … Read more
It is hard to provide a generic solution for Mac App Store receipt validation, mainly because this is a very sensitive piece of code that must be hard to bypass (cf. Apple documentation). These GitHub projects are very good starting points to learn about what steps must be performed in receipt validation: NPReceiptVerification ValidateStoreReceipt AppReceiptParser … Read more
On Xcode 11, you can turn off Sandboxing by removing it from the Signing & Capabilities tab:
What are window controllers actually for? Window controllers are tools to load a window from a NIB file and for managing the memory of the resources allocated in the NIB. Before there where NSWindowControllers one basically had to write the same code for every window or invent an own window controller class. Of course they … Read more
If I understand you correctly you have an NSData, say data, containing an encoded NSAttributedString. To reverse the process: NSAttributedString *nas = [[NSAttributedString alloc] initWithData:data options:nil documentAttributes:NULL error:NULL]; and to get the plain text without attributes you then do: NSString *str = [nas string];
copy and mutableCopy are defined in different protocols (NSCopying and NSMutableCopying, respectively), and NSArray conforms to both. mutableCopy is defined for NSArray (not just NSMutableArray) and allows you to make a mutable copy of an originally immutable array: // create an immutable array NSArray *arr = [NSArray arrayWithObjects: @”one”, @”two”, @”three”, nil ]; // create … Read more
This will remove all invalid characters anywhere in the filename based on Ismail’s invalid character set (I have not verified how complete his set is). – (NSString *)_sanitizeFileNameString:(NSString *)fileName { NSCharacterSet* illegalFileNameCharacters = [NSCharacterSet characterSetWithCharactersInString:@”/\\?%*|\”<>”]; return [[fileName componentsSeparatedByCharactersInSet:illegalFileNameCharacters] componentsJoinedByString:@””]; } Credit goes to Peter N Lewis for the idea to use componentsSeparatedByCharactersInSet: NSString – Convert … Read more
This is just an IB problem that happens all the time (I’m not sure why). To solve this, simply just resize the table view to the size smaller than the 2nd column, then drag it back to the size you want and the 2nd column will disappear.
The datasource supplies the data, the delegate supplies the behavior. In MVC, datasource is in the model layer and the delegate is in the control layer. Actually, on second thought, the datasource is usually controller that is lower down, closer to the model. I don’t think I’ve ever used a model object as my datasource.
