iphone - Does ABPersonViewController CFRetain its displayedPerson ABRecordRef? -

-

<पूर्व> ABRecordRef पता पुस्तिकारेकॉर्ड = ...; एबीएनईपर्सनव्यूकंट्रोलर * नयाप्रॉन्स व्यू कंट्रोलर = [[एबीएनवेपर्सन व्यू कंट्रोलर एलोॉक] इनट] ऑटोरेक्वेस]; NewPersonViewController.newPersonViewDelegate = प्रतिनिधि; NewPersonViewController.displayedPerson = addressBookRecord;

क्या यह सुरक्षित है 

  सीएफआरईईएज़े (पता पुस्तिका);

?

क्या इस बारे में कोई मानक कोर फ़ाउंडेशन पैटर्न नहीं है I

मुझे नहीं लगता है कि यह CFRelease को कॉल करने के लिए सुरक्षित है। प्रदर्शित किए गएप्रदर्शन को शीर्षलेख में निम्न प्रकार से परिभाषित किया गया है।
तो, प्रदर्शित किए गएप्रदर्शन को केवल असाइन किया गया है और कॉपी या बनाए रखा नहीं है जब हम मान सेट करते हैं।
इसलिए, मुझे लगता है कि हम इसे रिलीज़ नहीं कर सकते हैं।

objective c - iPhone and it's wireless area -

-
Is this a way to find other iPhones in the category of wireless areas? So I give an example. I'm staying at the airport somewhere I have an iPhone too. I and the other iPhone owners are playing the same game. Is there any way to warn me and the other player that we are close to each other? Does this work even if we are not on the same wireless network, or there is no wireless? And if there is any way to do this, can you give me some starting point? Like a link where I can learn something like this or maybe this is probably the name of this process, because I do not know how to search about this topic in Google. Thanks in advance! Can be completed with peer-to-peer discovery and connectivity you are describing Game Kit Framework Originally I thought it works only through Bluetooth, but after watching it immediately, it seems that WiFi is also supported. Hope it helps!

unix - Listing all shared memory segments used by a process on AIX5.3+ -

-
I would like to find all the shared memory segments used by a given process I am particularly interested in detecting shmid That's why I can use it in call (shmctl). On Solaris I will just read / proc / $ PID / map to find that information (field pr_shmid) The content of that file is defined by struct prmap_t in the sys / procfs format. Ax also has a / proc / $ PID / map file. Any project is a primate, but unfortunately it has been projected in pr_shmid field. Any ideas how can I get it on AIX5.3 +? I do not particularly know about AX, but I think that ipcs command is quite standard where SysV IPC is supported, so I want to get the ipcs -m command to give the appropriate code; If you can not find a better method, then there may be an option to parse its output.
