cocoa - How to make a periodic call to a method in objective c?

Question

if the question is not explained clearly please excuse me. I'm developing an iphone Client-Server app, i created all the classes, instances and ect. I can even send get and parse the response too.. Anyway, now i need to make my method be called in a defined period of time(for instance, call it repeatly in 10 seconds). I googled a lot and also take a look at

NSDate but i couldn't solve.. Now, can anyone please help me how to handle this situation? Thank you very much

You can create and schedule an instance of NSTimer to call your method on a given time interval. See in particular the following convenience creation method:

+ (NSTimer *)scheduledTimerWithTimeInterval:(NSTimeInterval)seconds target:(id)target selector:(SEL)aSelector userInfo:(id)userInfo repeats:(BOOL)repeats
