Iphone 滚动视图中的分页

_

viewdidload
{
NSArray*colors=[NSArray ARRAY WITHOBJECTS:[UIColor REDCLOR]、[UIColor GREENCLOR]、[UIColor blueColor]、nil]；
对于（int i=0；i

我用这段代码在scrollview中用不同的颜色显示分页，为了识别，我只想用图像代替颜色

viewdidload
{
    NSArray *colors = [NSArray arrayWithObjects:[UIColor redColor], [UIColor greenColor], [UIColor blueColor], nil];
    for (int i = 0; i < colors.count; i++) {
        CGRect frame;
        frame.origin.x = self.scrollView.frame.size.width * i;
        frame.origin.y = 0;
        frame.size = self.scrollView.frame.size;

        UIView *subview = [[UIView alloc] initWithFrame:frame];
        subview.backgroundColor = [colors objectAtIndex:i];
        [self.scrollView addSubview:subview];
        [subview release];
    }

    self.scrollView.contentSize = CGSizeMake(self.scrollView.frame.size.width * colors.count, self.scrollView.frame.size.height);

    self.pageControl.currentPage = 0;
    self.pageControl.numberOfPages = colors.count;
}

- (void)scrollViewDidScroll:(UIScrollView *)sender {
    if (!pageControlBeingUsed) {
        // Switch the indicator when more than 50% of the previous/next page is visible
        CGFloat pageWidth = self.scrollView.frame.size.width;
        int page = floor((self.scrollView.contentOffset.x - pageWidth / 2) / pageWidth) + 1;
        self.pageControl.currentPage = page;
    }
}

NSArray*colors=[NSArray阵列WithObjects:[UIImage ImageName:@]h1@2x“]，[UIImage ImageName:@”h2@2x“]，[UIImage ImageName:@”h2。1@2x“]，无]；
对于（int i=0；i

但是我只有两个视图，图像大小不适合它是去定位的。如何用上面的代码设置图像。请帮助我解决这个问题。 提前谢谢

NSArray *colors = [NSArray arrayWithObjects:[UIImage imageNamed:@"h1@2x"], [UIImage imageNamed:@"h2@2x"], [UIImage imageNamed:@"h2.1@2x"], nil];
    for (int i = 0; i < colors.count; i++) {
        CGRect frame;
        frame.origin.x = self.scrollView.frame.size.width * i;
        frame.origin.y = 0;
        frame.size = self.scrollView.frame.size;

        UIImageView*subview = [[UIView alloc] initWithFrame:frame];
        UIImage *imggg = [colors objectAtIndex:i];
        [subview setBackgroundColor:[UIColor colorWithPatternImage:imggg]];

        [self.scrollView addSubview:subview];
        [subview release];
    }

这看起来像是您的代码正在尝试执行的操作

如果您希望在每个页面上显示图像，请执行以下操作：

UIView *subview = [[[UIView alloc] initWithFrame:frame] autorelease];
[subview setBackgroundColor:[colors objectAtIndex:i]];

[[self scrollView] addSubview:subview];

要为每个页面创建多个图像，只需为页面使用UIImages数组

UIImage *img = [UIImage imageNamed:@"nameOfImageFile"];
UIImageView *imageView = [[[UIImageView alloc] initWithImage:img] autorelease];

[[self scrollView] addSubview:imageView];

---

我通过将数组中图像的大小减小到scrollview的大小来得到答案。我的scrollview大小是320424，我将图像的大小切片为320424。它工作得很好。谢谢。

NSArray *imageNames = [NSArray arrayWithObjects:@"image1Name", @"image2name", @"image3Name", nil];

UIImage *img = [UIImage imageNamed:[imageNames objectAtIndex:pageNumber]];
UIImageView *imageView = [[[UIImageView alloc] initWithImage:img] autorelease];

[[self scrollView] addSubview:imageView];

对于（int i=0；i），但在上面的代码中，我只获得@“nameOfImageFile”一个图像，但我在每个页面上都有多个图像要隐藏。有关多个图像的实现，请参阅“添加”。
