Question

-(void) addImageviewsToscrollview {
    int cx = 0;
    for (int i = 0; i < 4; i++) {
        UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"placeholder.png"]];

        CGRect rect = imageView.frame;
        rect.size.height = 100;
        rect.size.width = 100;
        rect.origin.x = cx;
        rect.origin.y = 0;

        imageView.tag = i;
        imageView.frame = rect;

        [self.imageScrollview addSubview:imageView];

        cx += imageView.frame.size.width+25;


    }
    [self.imageScrollview setContentSize:CGSizeMake(cx, [self.imageScrollview bounds].size.height)];
}

将ImageView添加到ScrollView。应用程序仅用于iPad，我使用的是故事板。我应该创建一个新类和一个新的UIViewController吗？

Answer 1

如果您想要使用任何标记访问任何UIImageView，请使用viewWithTag:

UIImageView *imageView = (UIImageView *)[self.imageScrollview viewWithTag:1];

只需使用您的代码更改数字1。

Answer 2

尝试通过启动1添加标记 imageView.tag = i + 1;

如何在scrollView中使用标记访问imageView？
