Re: performBatchUpdates: + removeObjectAtIndex: = EXC_BAD_ACCESS

I suspect your code is getting called on multiple threads, which would definitely cause crashes or heap corruption since you haven't added any synchronization around your objects. If you don't explicitly use multiple threads, maybe the UICollectionView is running your performBatchUpdates: block

Using NSArrayController with a complex, heterogeneous model

I'm working on a specialized CAD program with a fairly complicated model, not using Core Data. The data is hierarchical in nature, but not homogeneously. A "Part" in my app has a set of geometric primitives, and a set of labels (both have a common base class). These are two separate sets (arrays

performBatchUpdates: + removeObjectAtIndex: = EXC_BAD_ACCESS

Hi everyone, I'm getting an EXC_BAD_ACCESS from my specific combination of performBatchUpdates: and removeObjectAtIndex:. The application is within a framework I'm developing. The framework has a Mediator object, and multiple Manager dependencies. The Mediator combines input from all of the Manag

Just to clarify … this thread is about code, not about design. The appropriate initial directory offered by File > Open under various conditions is a design decision. The answer may vary for different apps. This thread is about the code that you write, or don’t, after the design decision is m

Re: Directory navigated to by menu File > Open

Yes, I missed that NSNavLastRootDirectory default. That explains the magic. Also, I’d forgotten about -[NSSavePanel setDirectoryURL:]. TextEdit does not invoke this method, so that does not explain the behavior. And yes I agree that overriding both -runModalOpenPanel:forTypes: and -beginOpen
