From Apple’s documentation
In Objective-C, there are three ways to create a timer. The following two class methods automatically register the new timer with the current NSRunLoop object in the default mode (NSDefaultRunLoopMode).
The following two class methods create timers that you may register at a later time by sending the message addTimer:forMode: to an NSRunLoop object.
Try using scheduledTimerWithTimeInterval:target:selector:userInfo:repeats:. –zootbobbalu
