NSTimer selector is not getting called

I have following code written to run NSTimer. But the NSTimer selector is not getting called.

.h file

@interface XViewController : UIViewController {
   NSTimer *repeatServerRequest;
}

@property(nonatomic, retain) NSTimer *repeatServerRequest;

- (void)checkForMinimunOnetimePinEntry;
- (void) initializeTimer;
- (void)stopTimer;

.m file

@synthesize repeatServerRequest;

- (void)checkForMinimunOnetimePinEntry {
   // some code
}

- (void) initializeTimer {
    repeatServerRequest = [NSTimer scheduledTimerWithTimeInterval:15.0
                                    target:self
                                    selector:@selector(checkForMinimunOnetimePinEntry)
                                    userInfo:nil
                                    repeats:YES];
}

- (void)stopTimer {
    [repeatServerRequest invalidate];
    [repeatServerRequest release];
    repeatServerRequest = nil;

//    [self.repeatServerRequest invalidate];
//    [self.repeatServerRequest release];
//    self.repeatServerRequest = nil;
}

What am I doing wrong?

Also answer me which one is right to use: self.repeatServerRequest or simply repeatServerRequest?? Thanks in advance!

Do you have an init method for your class ? Perhaps you didn't put it in your code but I prefer to ask ...

The problem is that you assign timer to a class field, not a property.

To make this code working, just put self. before repeatServerRequest =.

When you use self.repeatServerRequest, compiler invokes [self setRepeatServerRequest:...] and retains autoreleased timer.
