looping issue about icarousel

[iBCode]

@chakery
Just return YES for option iCarouselOptionWrap in the delegate method - (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option withDefault:(CGFloat)value, the rest return default values. That should work.

- (CGFloat)carousel:(iCarousel *)carousel valueForOption:(iCarouselOption)option withDefault:(CGFloat)value {
    switch (option) {
        case iCarouselOptionWrap:
            return YES;
            
        default:
            return value;
    }
}

Dear Nick,

How can I enable infinite scrolling?

Thx

Return YES from the carouselShouldWrap delegate method. Check the included example app for how to use this.

Sorry, what I want to say, is to scroll automatically, when the carousel appears, it start scrolling itself automatically.

Is that possible?

Thanks in advance

There's no correct way to do this right now without modifying the library.

You could do a pretty good approximation though by telling the carousel to scroll a very large number of steps over a very long time, using the scrollByNumberOfItems:duration: method.

If you specified 2000000000 (2 billion) for both parameters, it should cause the carousel to scroll slowly and continuously for 2 billion seconds, aka 63 years.

It might not work though due to floating point precision - I've not tried it. If it doesn't, try a smaller value like a million.

Thanks for you fast reply.

I've tried this (forgot to mention), but the acceleration was slow.

I tried 300 steps with duration equal to 300, but the acceleration was slow, and then in the middle very fast!! hehehe

Then I tried to change decelerationRate to 1.0f, and step over only to 1, but don't worked too.

Thanks,
João Paulo

Ah, okay. The problem is the easing (acceleration curve). I'll have to
modify the carousel library to make this work the way you want.

I'll file this as a feature request for the next version.
