iphone - CocoaAsyncSockets creating Connection on app startup but Reading/Writing from a view(s) -

-

i using cocoaasyncsockets library in order create tcp socket connection in app. currently, have created connection opening socket connection in didfinishlaunchingwithoptions method in appdelegate.m file. code looks so:

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:  (nsdictionary *)launchoptions {     socket = [[asyncsocket alloc] initwithdelegate:self];     [self connect];      self.window = [[[uiwindow alloc] initwithframe:[[uiscreen mainscreen] bounds]]    autorelease];     // override point customization after application launch.     self.viewcontroller = [[[tekmatrixviewcontroller alloc]     initwithnibname:@"tekmatrixviewcontroller" bundle:nil] autorelease];     self.window.rootviewcontroller = self.viewcontroller;     [self.window makekeyandvisible];     return yes; }

and here's connect method:

- (void)connect  {     [socket connecttohost:@"9.5.3.6" onport:11005 error:nil]; }

now, have been struggling how use read/write methods in views without having re-establish connection.

  • i have established tcp socket connection when application launches
  • i open socket in didfinishlaunchwithoptions method can create connection , stay connected entire time app running
  • i don't know how read/write from/to server views
  • i'm new socket/ios development, i'm hoping easiest possible solution

i appreciate can on this. i'm still pretty new ios , still picking on syntax, more details can provide, better off i'll be.

thanks help!

asyncsocket comes method writing:

- (void)writedata:(nsdata *)data withtimeout:(nstimeinterval)timeout tag:(long)tag;

and several variants of read methods, here one: (more header file of library)

- (void)readdatawithtimeout:(nstimeinterval)timeout tag:(long)tag;

you should samples code same website have downloaded asyncsocket library see how used. 1 thing keep in mind these methods asynchronous operations.

c++ - Troubles when compiling phash program -

-
here (probably) simple problem: i'm trying use perceptual hashing library phash ubuntu 11.10. had ffmpeg installed, way i've done: sudo apt-get install libphash0 sudo apt-get install libphash0-dev then tried compile program: #include <iostream> #include <phash.h> using namespace std; int main() { ulong64 myhash=0; ph_dct_imagehash("test.jpg", myhash); cout<<myhash<<endl; } when compiling, prints out: undefined reference `ph_dct_imagehash' any suggestion? should do? in advance! matteo monti you forgot link phash library, linker cannot find function. try adding -l phash gcc command line (or update makefile). if doesn't work, maybe you'll need specify library path (the location of *.a file) using -l "/usr/lib/"
