Thanks for the links, but my problem is a little different. The code in my library is executed fine, it's only crash when build in 'Release' mode and just in this category. Other categories work just fine. Thanks again. On Jul 31, 2011, at 2:02 AM, Jerry Krinock wrote: > > On 2011 Jul 30, at 2

Release build throw "unrecognized selector sent to instance" for a category method

Hi all. I'm working on tow projects. One is a Mac application and the other is a static library used for the application. Both are in the same Xcode workspace. In the library project I use several categories, one of them add some methods to NSDate to move a date around (ej: 'moveDateToNextMonth'

Ticker tape display

I have drawn text into a CALayer. I'd like to allow the user select the type of animation effect displayed, such as fading the text in/out by changing the CALayer's opacity. One of the effects I'm trying to do is a ticker tape display where a line of text is scrolled repeatedly from off-screen

Nib File Distortion

I have a complex form or screen in which I have buttons, images, text boxes, boxes. Since using Xcode 4, 5, I have had problems sizing the text boxes and the images and having them retain their new location. These items were nib was built using Xcode 3 and was properly aligned until I upgraded.

I tried ImageKit and it works great. Excellent quality. Thanks for the suggestion, Scott. I didn't have to do much more than change an NSImageView to an IKImageView in InterfaceBuilder and the code. However, there doesn't appear to be an easy way to print a CGImageRef (which you get from a

Thanks, I'll take a look at IK. I also found an Apple example application called ImageApp. It seems to work fine. No memory leaks. The approach for using CIImage seems to be to draw directly to an NSView rather than going to an NSImageView. Jim Merkel On Jul 29, 2011, at 11:46 PM, Scott
