core-foundation

I've got this issue being reported via Crashlytics, although I've been unable to replicate it locally, so I've got nothing to go on other than the stack trace below.. Not sure if the references to CoreLocation in the stack trace have anything to do with it, but I'm not sure what could possibly be the cause. My project is using ARC. Any clue?

My issue is that i need have. I need to achieve this programmatically. So for mac os x an application icon should have these sizes: I have 10 images. Each one i placed a badge in the right corner, the placement and position of this badge does not scale. So i 10 different images. How to make a ICNS out of this? I thought to use sips, however sips only takes one file and it does all the scalings: http://cc.bingj.com/cache.aspx?q=mac+icns+sips+argument+list&d=5035141870911884&mkt=en-US&setlang=en-US&w=n3PZcWn6bEPxt4O96PPLd6nugtVq5jDz Is there a way to make /usr/bin/sips take my 10 images and make

I'm playing with IOKit and have the following code, the general idea is to pass a platformExpert key to this small core foundation command line application and have it print the decoded string. The test case is "serial-number". The code below when run like: ./compiled serial-number Almost works but returns the last 4 characters of the serial number at the beginning of the string i.e. for an example serial such as C12D2JMPDDQX it would return DDQXC12D2JMPDDQX Any ideas? #include <CoreFoundation/CoreFoundation.h> #include <IOKit/IOKitLib.h> int main (int argc, const char * argv[]) { CFStringRef

I have written a server that listens on a specific port for incoming tcp connections. To manage the network connectivity I am using Streams (CFStream/NSStream). When a connection is esthablished I save all the information about this very connection in another instance of a dedicated class which is also set as the delegate for the streams. Now I want to get the public IP of the device that sends me a message through the already esthablished streams, in other words, I would like to store the IP of the stream's peer. I tried many things, but unfortunately I only get null-values. Is there a

I'm converting some of my older Objective-C code to Swift so I can move away from some deprecated methods but I keep getting a crash and so far I can't seem to figure out what's causing it. I'm getting a private key from a P12 Certificate and this method seems to work fine up until I get to the part where I actually need to get the dictionary from the CFArray, and even though the array has values in it the app keeps crashing. Here's the code that I have : func privateKeyFromCertificate(p12Name: String, withPassword password: String) -> SecKeyRef { let resourcePath: String = NSBundle.mainBundle

I have a few questions about ARC (automatic reference counting): CFURLRef url = (__bridge CFURLRef)[NSURL fileURLWithPath:appPath]; //Question 1: Here, I would expect the NSURL object to be autoreleased and //therefore the CFURLRef will also be available for “a while.” Is this correct? url = NULL; //Question 2: Will this cause the NSURL to be released immediately? NSURL *url = [NSURL fileURLWithPath:appPath]; url = nil; //Question 3: Does the “url = nil” result in an immediate release of the NSURL? NSURL *url = [[NSURL alloc] initWithString:@"/something"]; url = nil; //Question 4: What about

I'm aware that NSUrl is bridged to CFUrl. What are the Core Foundation equivalents for NSURLRequest and NSURLConnection so I can do something with a CFUrl object using pure C? There are not direct equivalents to NSURLRequest and NSURLConnection in Core Foundation, but you can use the lower-level CFHTTP functions in CFNetwork . For example, CFHTTPMessageRef myRequest = CFHTTPMessageCreateRequest(kCFAllocatorDefault, requestMethod, myUrl, kCFHTTPVersion1_1); CFHTTPMessageSetBody(myRequest, bodyData); CFHTTPMessageSetHeaderFieldValue(myRequest, headerField, value); CFReadStreamRef myReadStream =
