SWScrollView

Scroll view like Star Wars opening crawl.

##Requirements

iOS5.1 or later

##Installing By using CocoaPods

pod 'SWScrollView', '~> 0.0.1'

##Usage

Import header

#import"SWScrollView.h"

Instantiate SWScrollView along with start point and add view on any other view that you want.

CGPoint scrollStartPoint = CGPointMake(0, -600);
SWScrollView *scrollView = [SWScrollView scrollViewWithStartPoint:scrollStartPoint];
[self.view addSubview:scrollView];

If you want start animating automatically, call following method.

[scrollView startAnimationWithDuration:12.f completion:^(BOOL finished) {
// Write what you to do when finished this animation.
}];

##Customize

###Crawling message Of course You can change crawling message in SWScrollView.xib.

###Perspective of scroll view If you want to change perspective of scroll view. Edit -(void)setupScrollPerspective method in SWScrollView.m.

- (void)setupScrollPerspective
{
CATransform3D transform = CATransform3DIdentity;
//z distancefloat distance = [[UIScreen mainScreen] bounds].size.height;
float ratio = [[UIScreen mainScreen] bounds].size.height/[[UIScreen mainScreen] bounds].size.height;
transform.m34 = - ratio / distance;
transform = CATransform3DRotate(transform, 60.0f * M_PI / 180.0f, 1.f, 0.0f, 0.0f);
self.layer.transform = transform;
self.layer.zPosition = distance * ratio;
self.layer.position = CGPointMake([[UIScreen mainScreen] bounds].size.width/2,
[[UIScreen mainScreen] bounds].size.height/3);
}
