我是新的目标c。如何获取上传到服务器上的图像是横向模式还是纵向模式iphone
我有两个probelms。
我想要做的是显示像iphone galary这样的图像。我正在使用相同的滚动视频。我尝试过在很多帖子中使用fgalary和其他提及的galary，但是他们不是按照我的要求，因为我将不得不做很多定制。
//修改的注释
我想要做的就是在portrate模式在不同的帧大小采取类似CGRectMake（0，0，243，314），并显示图像，如果拍摄图像在横向模式下然后显示它在像CGRectMake（0，0，300，200）等单独的框架中。所有的图像都在服务器上上传，因为之前我在同一帧中显示所有图像，所以图像看起来很舒服，所以我正在像这样做。
我甚至试图从服务器获取图像加载的高度和宽度，如下面的代码所示，但即使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。

请注明它是什么你正在尝试去做，而当你运行你的代码时会发生什么。看起来你在这里有两个或三个问题，但我不确定。 – bdesham
我修改了我的问题，以便您可以清楚地知道我想问什么。 –
嗨使用图像方向属性.... self.rawImage.image.imageOrientation – Spynet
