我在滚动视图中添加了一个图像。但它不滚动...... 请帮忙解决问题..

感谢。

boxImage = [[UIImageView alloc]initWithFrame:CGRectMake(0, 44, 320, 372)];
        boxImage.image = [UIImage imageNamed:@"chapter1box.png"];
        textScroll = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 175, 320, 755)];
        scrollTextImg = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 775)];
        scrollTextImg.image = [UIImage imageNamed:@"chapter1narrationtext.png"];
        textScroll.backgroundColor = [UIColor clearColor];
        textScroll.scrollEnabled = YES;
        textScroll.pagingEnabled = YES;
        textScroll.directionalLockEnabled = YES;
        textScroll.autoresizesSubviews = YES;
        textScroll.contentSize = CGSizeMake(320, 775);
        [self.view addSubview:boxImage];
        [boxImage addSubview:textScroll];
        [textScroll addSubview:scrollTextImg];

Answer 1

UIImageView默认情况下userInteractionEnabled属性设置为NO。添加

boxImage.userInteractionEnabled = YES;

应该有帮助。

Answer 2

滚动视图大小必须小于滚动查看内容的大小。
