在iPhone中检测图片的图像位置
[英]Detecting image location of the picture in iPhone
问题描述
I am working on a camera app in which the pictures I take should store the location as to where they were taken. 
我正在开发一款相机应用程序，其中我拍摄的照片应该存储它们拍摄地点的位置。 So maybe after a while, if I want to know where a particular picture was taken, I should click on a button, say above my photo album, which should re-direct me to a mapview. 所以也许过了一段时间，如果我想知道拍摄特定照片的位置，我应该点击一个按钮，比如说我的相册上面，我应该重新引导我到mapview。 There, it should show the places where i've taken all my pictures, with an album for each place. 在那里，它应该显示我拍摄所有照片的地方，每个地方都有一张专辑。
Any idea on how to make this work? 有关如何使这项工作的任何想法？

Add MetaData to UIImage . 将MetaData添加到UIImage 。 Same metadata of UIImage can be used to know images's location. UIImage的相同元数据可用于了解图像的位置。
Refer Save_Photo_to_Album_with_Metadata 请参阅Save_Photo_to_Album_with_Metadata
