Get GPS location from MLMediaObject on OS X

阅读更多关于 Get GPS location from MLMediaObject on OS X

问题 I'm getting started with the Media Library Framework on OS X, specifically with regard to accessing a user's Photos library. After a lot of wrangling I was able to get access to each photo as a MLMediaObject, but now I've hit a roadblock: How can I access the GPS location of the photo, from the MLMediaObject?

How do I use [camera takePhoto] and edit using UIImagePicker - UIImagePickerController.allowsEditing = YES

阅读更多关于 How do I use [camera takePhoto] and edit using UIImagePicker - UIImagePickerController.allowsEditing = YES

I'm going to feel dumb but I've searched everywhere and have not found an answer. I've been able to pull up the "edit" view using the default camera's controls. However I threw an overlay on it and I have a UIButton hooked up to IBAction take photo which looks like [UIImagePickerController takePicture]. However, it totally skips the editing part even though I set allows editing to YES. Is there another command to call it? Right now, it just goes straight to didFinishPickingMediaWithInfo. camera.sourceType = UIImagePickerControllerSourceTypeCamera; camera.cameraDevice =

问题 Can anyone share code (or point me to Android sample code) to help me add images to an album in the Media Store (Gallery). In my app I download images from our server, and also take new images using the camera (via Intent). I would like to organize those images in an app-specific album, similar to what the Facebook (and other apps) app does, keeping related images all neatly organized. I looked into this a while ago, following the Media Store API docs, and it didn't work for me....so need
