Question

HI guys,

==>in my application i have used three different thread code for one of them is here all thread are of same kind
==>i have defined two thread in appdelegate class
==>one in the root view controller
==>all the thread having different sleep time

My question is that does any thread may get killed by the other and the invocation time for one thread get affected by the other?

-(void)PostData
{
NSAutoreleasePool *apool = [[NSAutoreleasePool alloc] init];// we are responsible for the memory pool

while(TRUE)
{       
    [self performSelectorOnMainThread:@selector(PostAllthedata) 
                           withObject:nil 
                        waitUntilDone:YES]; 
    [NSThread sleepForTimeInterval:150]; 

}
[apool release];
}

-(void)PostAllthedata
{
PostSyncData *objPostSyncData=[[PostSyncData alloc]init];
[objPostSyncData release];    
}

The Apple reference documents on the use of the method - (void)performSelectorOnMainThread:(SEL)aSelector withObject:(id)arg waitUntilDone:(BOOL)wait states

Multiple calls to this method from the
same thread cause the corresponding
selectors to be queued and performed
in the same same order in which the
calls were made.
