i working on application , have check net connectivity. using 2 files reachability.h , reachability.m. have show alert when net not working.

but when observer check net shows alert view more 1 time. , times shows alert more 9-10 times. code here:

in .h file

reachability* internetreachable; reachability* hostreachable; networkstatus internetstatus;

in .m file

internetreachable = [[reachability reachabilityforinternetconnection] retain]; [internetreachable startnotifier]; [[nsnotificationcenter defaultcenter] addobserver:self selector:@selector(checknetworkstatus:) name:kreachabilitychangednotification object:nil]; hostreachable = [[reachability reachabilitywithhostname: @"www.apple.com"] retain]; [hostreachable startnotifier]; - (void) checknetworkstatus:(nsnotification *)notice { internetstatus = [internetreachable currentreachabilitystatus]; if (internetstatus != notreachable){ nslog(@"internet on"); } else { uialertview *alert = [[uialertview alloc] initwithtitle:@"error!" message:@"server not connected or down!" delegate:self cancelbuttontitle:@"ok" otherbuttontitles:nil]; [alert show]; [alert release]; internetcount++; } }

this code in delegate , using code in other classes ever have check internet

plz help

i don't utilize reachability because i've had problems you, created own implementation. import header file below , phone call [self networkisreachable] check net connection.

#import <netinet/in.h> - (bool)networkisreachable { struct sockaddr_in zeroaddress; bzero(&zeroaddress, sizeof(zeroaddress)); zeroaddress.sin_len = sizeof(zeroaddress); zeroaddress.sin_family = af_inet; scnetworkreachabilityref defaultroutereachability = scnetworkreachabilitycreatewithaddress(null, (struct sockaddr *)&zeroaddress); scnetworkreachabilityflags flags; bool gotflags = scnetworkreachabilitygetflags(defaultroutereachability, &flags); cfrelease(defaultroutereachability); if (!gotflags) { homecoming no; } bool isreachable = flags & kscnetworkreachabilityflagsreachable; bool noconnectionrequired = !(flags & kscnetworkreachabilityflagsconnectionrequired); if ((flags & kscnetworkreachabilityflagsiswwan)) { noconnectionrequired = yes; } homecoming (isreachable && noconnectionrequired) ? yes : no; }

intellij idea - Update external libraries with intelij and java - simple plenty really. i'm using apache jars, i'll create changes jar's every often. these jars listed external libs in intelij (i.e classpath looking install dir of jar's). when create changes intelij doesn't seem know new implementation. have remove jar external library , re-ad it. does know have intelij picks changes automatically ? i've done clean , rebuild project had little effect. you can go preferences -> build, execution, deployment -> build tools -> maven -> importing , check box says import maven projects automatically . in mac, can command + shift + a , come in action reimport , click on reimport maven projects . intellij-idea
