view-based nstableview advice

Hi, Just trying to make sure I'm on the right track here...so I'm doing my first view-based table view and I do like how I can set a lot of things up in IB like text fields, etc. But I want to customize the rows (give them a gradient, etc.) so am I understanding correctly that I should drag ou

Crash in NSBitmapImageRep representationUsingType: NSPNGFileType for 8-bit grayscale

I have code that produces a PNG file from a cropped version of a bitmap that can be 8-bit grayscale, 16-bit grayscale, 24-bit color, or 32-bit color+alpha. It basically looks like this: - (NSData *) getPNGCropped: (NSRect)cropRect { unsigned char* planes[5]; int offset =(int)cropRect

Passing data through a segue

I have a simple storyboard app with a push segue from a master table to a detail controller. In the past, I'd implement -didSelectRowAtIndexPath, get the object for that row, create the detail view controller, assign the object to it, and push it. Now I don't really see a nice way to do that wi

Re: Passing data through a segue

Oh. It seems I can't even implement didSelectRowAtIndexPath; it's not getting called. If the docs for didSelectRowAtIndexPath had been updated to talk about it's use in the context of segues, I wouldn't have to read every word of every other doc published to try to find the answer. -- Rick O

Re: Passing data through a segue

in -didSelectRowAtIndexPath you get the object then you call performSegue:withIdentifer:sender with the object you just got as the sender. in -prepareForSegue you have the destination view controller from the segue object and you have the 'object' you used as sender, the object from your table

Re: Passing data through a segue

Thanks for the quick response. I think I'm okay with sending stuff through the sender parameter, although I do agree it's a bit ugly. Problem is, my didSelectRowAtIndexPath isn't getting called... :-( The delegate is set correctly, so I'm assuming iOS doesn't call it in the presence of segues?

Re: Passing data through a segue

Ah, finally found some docs. In the View Controller Programming Guide, "Configuring the Destination Controller When a Segue is Triggered", it uses -indexPathForSelectedRow. On Apr 2, 2012, at 4:15 , Rick Mann wrote: > Thanks for the quick response. > > I think I'm okay with sending stuff thro

Re: Passing data through a segue

What's your trigger for the segue? Have you set it up in IB so that a select on the table cell triggers it automagically? If so then no you have probably lost control of didSelect... So you have two choices. Either do the second thing I said, find the sending tableViewController, get its selec

Changed cell identifier, now it's not found?

Huh. I changed the name of one of my prototype cells in the storyboard file, and changed it in the code, and now iOS can't find it. I've copied-and-pasted the name used in the string I pass into the IB field just to be sure there wasn't a typo, but I get an exception when I try to dequeue it. An

Ugh, nvm, I can't read. The class I added didn't get added to the target, and it was complaining about the class missing. Seems like Xc4 always forgets to add new files to the target. Huh. I changed the name of one of my prototype cells in the storyboard file, and changed it in the co

Re: Stenography

This may be a case of selective perception. Apparently Cocoa-developer are more familiar with steganography than shorthand. :) Since the original poster explicitly wrote "stenography", it seems plausible that was what he meant. In fact, i know that trainee journalists in the UK are taught sho
