photos

问题 I am developing a iPhone photo app in which there is one view, where I am showing all the images taken through that app with the help of uiscrollview. First I simply loaded the scrollview with all the present images. But it made the app slow and also caused the crash giving the following warning: Received memory warning. Level=2 I googled a lot and found that the reason for so may be loading such heavy images all together on a view are resulting in memory warning and crash afterwards. So I

问题 Is there any way to iterate through all images stored in a blackberry device. I have seen this example which iterates over the whole file system and scans each file. I am wondering is there any cheaper way of doing the same. Something that directly looks into the image directory? Thanks 回答1: Using System.getProperty(String key) it is possible to get image storage dirs on device: Key "fileconn.dir.memorycard.photos". Returns default directory for storing photos on SD Card. It should be

问题 I've been pulling photos from my android device to my linux OS like this: $ adb pull <what-to-pull> <where-to-place> In the future I would prefer to pull only the ones I don't alreay have. What's the best way to do this? Maybe I could put all the photos I've downloaded to the same folder and skip the ones with names that already exist in the folder I'm pulling from? How to do that? Is that even the best way? Does an easier way to do this exist? If so... how? I'm on arch linux by the way, in

问题 Recently used Google Takeout to download 60GB+ of photos and video from Google+. This has resulted in plenty of files -- but valuable metadata including the original dates for photos and often location is stored in a separate metadata.json file for every album, instead of in EXIF. This means I can't import it to any other photo service without essentially scrambling all the dates based on what G+ made automatic edits to the photos. Can't find an answer anywhere -- solving this should help

问题 I have tried to getting absolute path and I got the success too but when I try with the cloud images to get that image and used in application file is not find and getting null. I am implementing to receive files from another app like when you select image from Photos, Gallery or File application and share image by using my application. Here I got the Uri content://com.google.android.apps.photos.contentprovider/0/1/mediaKey%3A%2FAF1QipOFLMMm8uXbeDMQk-P4S0Hx1dlmRDMr4SFABfVi/ACTUAL/61235243

问题 Basically, when they hit "Don't Allow", the imagePicker isn't showing the screen that gives the user the instructions to go into privacy settings and turn it on. If I kill the app and go back, the privacy setting is there. So I figured I probably need to manually do this when they touch "Don't Allow". Is there a callback for when a user allows or doesn't allow access to their photo library? I can't find it in the docs. At the very least I could dismiss the imageView. Thanks! 回答1: If this is

问题 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.

问题 I want to parse all images from my MacOS Photos Library, using PHAsset. However all examples I find are only working for iOS, like the one below, where the last line, which retrieves the assets is not available on macos framework: NSMutableArray *photos = [[NSMutableArray alloc] init]; PHFetchOptions *allPhotosOptions = [[PHFetchOptions alloc] init]; allPhotosOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]]; // Below compilation error as

问题 I need a little bit of help in here, I have a method that saves an UIImage to the camera roll without problems in iOS 8. The method is the following [[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{ [PHAssetChangeRequest creationRequestForAssetFromImage:image]; }completionHandler:^(BOOL success, NSError *error) { if(success){ NSLog(@"worked"); }else{ NSLog(@"Error: %@", error); } }]; I need to adapt that code, so that the image instead of saving the UIImage to the camera roll, it saves

问题 I want to connect an external camera to an iPhone (the camera built into the iPhone is inadequate for my needs) and then write an iPhone app that allows me to send a signal to the external camera when I desire to take a picture and then immediately download the taken photo onto my iPhone so that I can send it wirelessly to a server somewhere else. I have a lot of experience with web programming and JS, but I have no experience with iPhone apps, and I'm not sure if what I want to do is even
