我是目标 c 的新手。
我有两个问题。
我想做的是显示像 iphone galary 这样的图像。我正在使用滚动视频。我尝试在许多帖子中使用 fgalary 和其他提到的 galary，但它们不符合我的要求，因为我必须在其中进行许多自定义。
//修改评论
我想要做的是以单独的帧大小显示以移植模式拍摄的图像，如 CGRectMake(0, 0, 243, 314)，如果图像是在横向模式下拍摄的，则以单独的帧显示，如 CGRectMake(0, 0, 300, 200)..所有图像都上传到服务器上，就像之前我在同一帧中显示所有图像一样，所以图像在显示时看起来会拉伸，所以我就是这样做的。
我什至尝试从服务器获取图像加载的高度和宽度，如下面的代码所示，但这甚至不适用于从服务器加载的图像。请建议我一些更好的方法来解决我的问题。
