POChange View in UIScrollView with NSTimer
text
Body
copied!<p>I am using the following code in order to create a <code>UIScrollView</code>:</p> <pre><code>UIScrollView *scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)]; scroll.pagingEnabled = YES; NSInteger numberOfViews = 3; for (int i = 0; i < numberOfViews; i++) { CGFloat yOrigin = i * self.view.frame.size.width; UIView *awesomeView = [[UIView alloc] initWithFrame:CGRectMake(yOrigin, 0, self.view.frame.size.width, self.view.frame.size.height)]; awesomeView.backgroundColor = [UIColor colorWithRed:0.5/i green:0.5 blue:0.5 alpha:1]; [scroll addSubview:awesomeView]; } scroll.contentSize = CGSizeMake(self.view.frame.size.width * numberOfViews, self.view.frame.size.height); [self.view addSubview:scroll]; </code></pre> <p>The Question is: How do I implement an <code>NSTimer</code> in order to change the page every 4 seconds? </p> <pre><code> [NSTimer scheduledTimerWithTimeInterval:4.0f target:self selector:@selector(updateCounter:) userInfo:nil repeats:YES]; </code></pre> <p>I am struggling to write the updateCounter method. Please help</p> <pre><code>- (void)updateCounter:(NSTimer *)theTimer { NSInteger numberOfViews = 3; int i = 0; i++; if (i < numberOfViews) { yOrigin = i * self.view.frame.size.width; [scroll scrollRectToVisible:CGRectMake(yOrigin, 0, self.view.frame.size.width, self.view.frame.size.height) animated:YES]; } return; } </code></pre> <p>OK, so with this code, <code>NSTimer</code> changes from <em>view 1</em> to <em>view 2</em>, but it stops, it does not change after the next 4 seconds to <em>view 3</em>. What I want to do is to change from <em>view 1</em>, to <em>view</em> 2, after 4 seconds, then to <em>view 3</em>, after 4 seconds, and so on. I want to have as many views as I need.</p>

An individual column

Larger individual text columns get their own page to allow for proper reading.
