objective c - memory management: am i doing something wrong here? -

-

In my iPhone application a very small number of cases, I get an accident after the loop in the code given below Is: 

  ABAddressBookRef AddressBookEnter = ABAddressBookCreate (); CFMutableArrayRef abContacts = (CFMutableArrayRef) ABAddressBookCopyArrayOfAllPeople (Address Bookinit); // All contacts get the array of CFArraySortValues ​​(abContacts, CFRangeMake (0, CFArrayGetCount (abContacts)), (CFComparatorFunction), ABPersonComparePeopleByName, (Zero *), ABPersonGetSortOrdering ()), NSArray * copypeople = (NSArray *) abContacts; NSMutableArray * tempTheadlist = [[NSMutableArray alloc] init]; For (; I & lt; i = 0 int copypeople.count; i ++) {NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init]; ABRecordRef record = [copyEople ObjectOutIndexX: i]; If (Blah Blah) [tempThreadList addObject: someObject]; [Bridge release]; } // End of accident after loop ends (tempTheadlist.count> 0) [NSThread detachNewThreadSelector: @selector (loading_pictures :) toTarget: auto withObject: tempTheadlist]; [TempTheadlist Release]; [Copy release]; CFRelease (addressBookInit);

Is any reason why it should crash here at any point?

"text" itemprop = "text">

(1) ABAddressBookCopyArrayOfAllPeople () a CFArrayRef , Not a CFMutableArrayRef .

(2) CFArrayRef, CFMutableArrayRef, and NSArray inserted among all are irrelevant. NSArray and CFArray are synonymous.

(3) The autoreclip pool in the () loop is irrelevant. Any new objects can not be made in () loop, and thus nothing should come into the pool. Neither objectAtIndex: will maintain / autorer objects.

(4) That you are sorting the ARM returned by all people (AB) Address Archippi, possibly a crash may be triggered. This function is declared as returning CFArrayRef () and it will be considered irreversible.

If the app is crashing, then post the accidental backtrack. Without it, it is difficult to say how specially the accident is being triggered, is this crash in the thread which runs the code above? ... or crashing in a newly created thread?

c# - How to capture HTTP packet with SharpPcap -

-
I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

I do not understand why this script does not work. It has something to do within AJAX PostScript / Function. Right now, when I submit my form, it runs php code on the same page. What it should do, send the values ​​of the form for Project_Azax.fp, then there will be a refund of success on the page which is correct or false. $ (document) .ready (function () {$ ('div # didIt').
