很不幸，不行。
正如 iOS 的“相机编程主题”中所述，除了默认设置之外，如果您想获得其他内容，则必须实现自定义裁剪 GUI：
"When using built-in editing controls, the image picker controller enforces certain options. For still images, the picker enforces a square cropping as well as a maximum pixel dimension. For movies, the picker enforces a maximum movie length and resolution. If you want to let the user edit full-size media, or specify custom cropping, you must provide your own editing UI."
如果您想让用户编辑完整大小的媒体，或指定自定义裁剪，则必须提供自己的编辑界面。请参考此链接: http://developer.apple.com/library/ios/#documentation/AudioVideo/Conceptual/CameraAndPhotoLib_TopicsForIOS/Articles/PickinganItemfromthePhotoLibrary.html#//apple_ref/doc/uid/TP40010408-SW1
