Question

我有一张照片，它的大小是1024 * 768，我在图片中添加了一个UIScrollview，问题是当我缩放一切似乎都没问题，直到我转到照片的右边或下边缘我看到有图像下方有一个自由空间，换句话说，缩放是可以的，但是图像没有变焦，而且它的边缘没有连接到uiscrollview的边缘，所以我看到图像下方和右侧的空间，如果我放大了更多空间越来越大，这里是代码：请帮帮我

    scrollASync = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
    UIImageView *imgv = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 1024, 768)];
    [imgv setImage:[UIImage imageNamed:@"11.jpg"]];

    [scrollASync setUserInteractionEnabled:YES];
    [scrollASync setMultipleTouchEnabled:YES];
    [scrollASync setMinimumZoomScale:1.0];
    [scrollASync setMaximumZoomScale:3.0];
    [scrollASync setDelegate:self];
    [scrollASync setBounces:YES];
    [scrollASync setBouncesZoom:YES];
    [scrollASync setClipsToBounds:YES];
    [scrollASync setContentMode:UIViewContentModeScaleToFill];
    [scrollASync addSubview:imgv];
    [self.view addSubview:scrollASync];

Answer 1

尝试使用

imgv.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | 
        UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin;

希望它有所帮助...
