Example of [NSTimer scheduledTimerWithTimeInterval]
- (void) viewDidLoad {
NSInvocation *updateDisplayInvocation = [NSInvocation invocationWithMethodSignature:[self methodSignatureForSelector: @selector (myMethod)]];
[updateDisplayInvocation setSelector: @selector (myMethod)];
[updateDisplayInvocation setTarget: self];
NSTimer *audioDisplayUpdateTimer;
audioDisplayUpdateTimer = [NSTimer scheduledTimerWithTimeInterval:3.0 invocation:updateDisplayInvocation repeats:YES];
[super viewDidLoad];
}
- (void) myMethod {
NSLog(@"Method execution");
}
