  • Cocoa touch - GameKit GKPeerPickerController devices

    - by teepusink
    Hi, I'm now testing GKPeerPickerController. I have a simple app that just have a button and do GKPeerPickerController on a device. However, all it does is "Looking for other iPhones or iPod touches..." I do have another device nearby with bluetooth turned on BUT without the app installed. Does that other device also need to have the app installed? Thanks, Tee

  • [Cocoa] NSImage transparency

    - by ndg
    I'm trying to set a custom drag icon for use in an NSTableView. Everything seems to work but I've run into a problem due to my inexperience with Quartz. - (NSImage *)dragImageForRowsWithIndexes:(NSIndexSet *)dragRows tableColumns:(NSArray *)tableColumns event:(NSEvent *)dragEvent offset:(NSPointPointer)dragImageOffset { NSImage *dragImage = [NSImage imageNamed:@"icon.png"]; NSString *count = [NSString stringWithFormat:@"%d", [dragRows count]]; [dragImage lockFocus]; [dragImage compositeToPoint:NSZeroPoint fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:0.5]; [count drawAtPoint:NSZeroPoint withAttributes:nil]; [dragImage unlockFocus]; return dragImage; } Essentially what I'm looking to do is render my icon.png file with 50% opacity along with an NSString which shows the number of rows currently being dragged. The issue I'm seeing is that my NSString renders with a low opacity, but not my icon.

  • Creating a "permanent" Cocoa object

    - by quixoto
    I have an object factory that hands out instances of certain "constant" objects. I'd like these objects to be protected against bad memory management by clients. This is how I've overridden the class's key methods. Am I missing anything (code or other considerations)? - (id)retain { return self; } - (NSUInteger)retainCount { return UINT_MAX; } - (void)release { // nothing. }

  • fork within Cocoa application

    - by liuliu
    My problem is not the best scenario for fork(). However, this is the best func I can get. I am working on a Firefox plugin on Mac OSX. To make it robust, I need to create a new process to run my plugin. The problem is, when I forked a new process, much like this: if (fork() == 0) exit(other_main()); However, since the state is not cleaned, I cannot properly initialized my new process (call NSApplicationLoad etc.). Any ideas? BTW, I certainly don't want create a new binary and exec it.

  • Sending a 'copy' command in cocoa

    - by Ben Packard
    Is there any way to send a copy (command-c) instruction without using a cgEvent to mimic the keystrokes? I don't have access to the text field in the application I want to take text from, so need to replicate manually copying to the clipboard, and there seemss to be a bug with cgevent posting. According the Quartz documentation, to type a capital Z I should use: CGEventRef event1, event2, event3, event4; event1 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, true); event2 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)6, true); event3 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)6, false); event4 = CGEventCreateKeyboardEvent (NULL, (CGKeyCode)56, false); However, if I attach this set of instuctions to an NSTimer, it only works the first time it is fired. example output: ZzzZzzzzZZzzZ (vs expected ZZZZZZZZZ). How else might I send a copy command to the active window?

  • Cocoa Scripting Bridge and <contents> element

    - by Stephen
    So, the application I'm trying to script has a scripting definition file that includes a <contents> element, which is an "implicitly specified container." The question, how do I get at what's inside this element using Scripting Bridge? Or alternatively, how do I send the Apple Event necessary to retrieve it and then transform what I get back into an SBObject? I already tried: [document nameOfKey] document.nameofKey [document contents] document.contents

  • C++ for Ruby scripters

    - by Aaron Cohen
    I am a fairly capable Ruby scripter/programmer, but have been feeling pressure to branch out into C++. I haven't been able to find any sites along the lines of "C++ for Ruby Programmers". This site exists for Python (which is quite similar, I know). Does anyone know of a guide that can help me translate my Ruby 'thoughts' into C++?

  • Problems Installing Eclipse and Ruby Plugin

    - by Jesse J
    I installed Eclipse on my Ubuntu machine and then the Ruby Development Tools (RDT), but it would crash when I try to alter certain features, like having line numbers, how far back to have history, and the code coloring scheme didn't work fully. I decided to try to uninstall Eclipse by doing sudo aptitude remove Eclipse and then sudo aptitude install eclipse but instead it installed it back with the broken Ruby plugin. I also tried aptitude purge but that didn't help either. How can I freshly reinstall Eclipse and get a properly working Ruby plugin?

  • Mac OS - Download an save an image file on HDD with Cocoa

    - by Julien
    I'm building a program, and I'm quite confident using Objective-C, but I don't know how to programmatically download a file from the web and copy it on the hard drive. I started with : NSString url = @"http://spiritofpolo.com/images/logo.png"; NSData* data = [NSData dataWithContentsOfURL:[NSURL URLWithString:url]]; But then I don't know what to do with the data... that sucks, no ;) Can somebody help?

  • Clarification on Threads and Run Loops In Cocoa

    - by dubbeat
    I'm trying to learn about threading and I'm thoroughly confused. I'm sure all the answers are there in the apple docs but I just found it really hard to breakdown and digest. Maybe somebody could clear a thing or 2 up for me. 1)performSelectorOnMainThread Does the above simply register an event in the main run loop or is it somehow a new thread even though the method says "mainThread"? If the purpose of threads is to relieve processing on the main thread how does this help? 2) RunLoops Is it true that if I want to create a completely seperate thread I use "detachNewThreadSelector"? Does calling start on this initiate a default run loop for the thread that has been created? If so where do run loops come into it? 3) And Finally , I've seen examples using NSOperationQueue. Is it true to say that If you use performSelectorOnMainThread the threads are in a queue anyway so NSOperation is not needed? 4) Should I forget about all of this and just use the Grand Central Dispatch instead?
