Question

我想知道如何使用按钮作为对象创建分页UIScrollView？

到目前为止，我已经想出用图像制作类似的UIScrollView，看起来像这样：

    - (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

    NSArray *pictures = [NSArray arrayWithObjects: [UIImage imageNamed:@"nr1"], [UIImage imageNamed:@"nr2"], nil];


    for (int i = 0; i < pictures.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 = [[UIImageView alloc] initWithFrame:frame];
        subview.image = [pictures objectAtIndex:i];
        [self.scrollView addSubview:subview];
    }

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

}

任何教程都将受到赞赏：）

您只需添加按钮而不是图像

替换此

UIImageView *subview = [[UIImageView alloc] initWithFrame:frame];
subview.image = [pictures objectAtIndex:i];
[self.scrollView addSubview:subview];

使用

UIButton *subview = [UIButton buttonWithType:UIButtonTypeRoundedRect];
subview.frame = frame;
[subview setTitle:@"Test" forState:UIControlStateNormal];
[self.scrollView addSubview:subview];
