here is my question:
Is it possible to increase the scheduledTimerWithTimeInterval:2 for example of "3" after 10 seconds in ViewDidLoad for example.
E.g., from this:
[NSTimer scheduledTimerWithTimeInterval:2 target:self selector:@selector(createNewImage) userInfo:nil repeats:YES];
to this:
[NSTimer scheduledTimerWithTimeInterval:3 target:self selector:@selector(createNewImage) userInfo:nil repeats:YES];
thank you sorry for my english I french :/
Reschedule the timer recursively like this:
float gap = 0.50;
[NSTimer scheduledTimerWithTimeInterval:gap target:self selector:@selector(onTimer) userInfo:nil repeats:NO];
-(void) onTimer {
gap = gap + .05;
[NSTimer scheduledTimerWithTimeInterval:gap target:self selector:@selector(onTimer) userInfo:nil repeats:NO];
}
========
Or according to How can I update my NSTimer as I change the value of the time interval
Invalidate it with:
[myTimer invalidate];
Then create a new one with the new time. You may have to set it to nil first as well.
myTimer = nil;
myTimer = [NSTimer scheduledTimerWithTimeInterval:mySlider.value
target:self
selector:@selector(myMethod)
userInfo:nil
repeats:YES];
Use setFireDate: to reschedule the timer. You'll need to keep track of the timer in an ivar. For example:
@property (nonatomic, readwrite, retain) NSTimer *timer;
@synthesize timer=timer_;
- (void)setTimer:(NSTimer *)aTimer {
if (timer_ != aTimer) {
[aTimer retain];
[timer_ invalidate];
[timer_ release];
timer_ = aTimer;
}
- (void)dealloc {
[timer_ invalidate];
[timer_ release];
}
...
self.timer = [NSTimer scheduledTimerWithTimeInterval:...];
...
self.timer.fireDate = [NSDate dateWithTimeIntervalSinceNow:3]; // reschedule for 3 seconds from now
