+ (nsthread*)networkthread {     static nsthread *networkthread = nil;     static dispatch_once_t oncetoken;     dispatch_once(&oncetoken, ^{         networkthread = [[nsthread alloc] initwithtarget:self selector:@selector(networkthreadmain:) object:nil];          [networkthread start];     });      return networkthread; }  + (void)networkthreadmain:(id)sender {     while (yes)     {         @autoreleasepool {             [[nsrunloop currentrunloop] run];         }     } }  - (void)scheduleinthread:(id)sender {     [inputstream scheduleinrunloop:[nsrunloop currentrunloop] formode:nsrunloopcommonmodes];     [inputstream open]; }  - (void)closethread {         [inputstream close];     [inputstream removefromrunloop:[nsrunloop currentrunloop] formode:nsrunloopcommonmodes];     [inputstream release];     inputstream = nil; }

call made when trying connect inputstream:

[self performselector:@selector(scheduleinthread:) onthread:[[self class] networkthread] withobject:nil waituntildone:yes];
