I'm trying to get pagecontrol to work. Right now I can scroll to the 2nd page, but the background is not changing (im changing the background to make sure it works fine). When I use pageControl to flip through pages, the background changes fine. I think I need to call pageTurning in scrollViewDidScroll but adding [self pageTurningage]; does not work
this is what I have atm:
any ideas?
this is what I have atm:
Code:
static int kNumberOfPages = 2;
#import "AppDelegate.h"
@implementation AppDelegate
@synthesize window = _window;
@synthesize pageControl, scrollView, viewControllers;
-(IBAction)changePage:(id)sender
{
pageControlUsed = YES;
}
-(void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView{
pageControlUsed = NO;
}
-(void)scrollViewDidScroll:(UIScrollView *)sender
{
if(pageControlUsed){
return;
}
CGFloat pageWidth = scrollView.frame.size.width;
int page = floor((scrollView.contentOffset.x - pageWidth / 2)/pageWidth) + 1;
pageControl.currentPage = page;
}
-(void)pageTurning:(UIPageControl *)pageController{
NSInteger nextPage = [pageController currentPage];
switch (nextPage) {
case 0:
scrollView.backgroundColor = [UIColor blueColor];
break;
case 1:
scrollView.backgroundColor = [UIColor redColor];
default:
break;
}
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
scrollView.contentSize = CGSizeMake(scrollView.frame.size.width * kNumberOfPages, scrollView.frame.size.height);
scrollView.delegate = self;
[pageControl addTarget:self action:@selector(pageTurning:) forControlEvents:UIControlEventValueChanged];
pageControl.currentPage = 0;
[self pageTurning:pageControl];
//self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
// Override point for customization after application launch.
//self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
any ideas?
