问题 I have read couple of posts on how to save brushed data, however, on trying the suggestions on these posts (this, this, this, this and this), none of them seem to be working. One of the problem I encountered while trying these suggestions is that the program runs all the way through the end before any data is brushed, and therefore, the saved data is an empty matrix. My objectives are: Brush the data, and Save the brushed data. This is what I tried from here but it didn't seem to work: t=0:0

问题 In my app I save an XML file to the user's SD card by doing File newxmlfile = new File(Environment.getExternalStorageDirectory() + "/Message.xml"); But not all users have SD-cards in their phone and therefore my app is likely to crash.

问题 This is as simple as it gets. Make RGB image, one pixel big. Set pixel value to (a,b,c). Save. Problem is, the saved image has a different pixel value then (a,b,c). Usually, with +-1 on one of the channels, as if it were random noise, but its consistent. Heres the code: from PIL import Image newImg = Image.new('RGB', (1,1), "black") pixels = newImg.load() pixels[0,0] = (0,3,0) newImg.save("point.jpg") savedImage = Image.open("point.jpg") pixelsSaved = savedImage.load() print pixels[0,0] print

问题 I have saved data which was saved using NSUserDefaults. I was under the impression that if there was nothing saved to the key already (first time app is run) it would default to 0. This however doesn't seem to be the case. Here is what I have: To save: - (void)viewWillDisappear:(BOOL)animated { [[NSUserDefaults standardUserDefaults] setInteger:setbatteryHealthCalculated forKey:@"healthValue"]; [[NSUserDefaults standardUserDefaults] synchronize]; } To load: - (void) viewWillAppear:(BOOL

问题 In my app I need to save a double value (high score) and String (player name) what should i use to get this. any idea will be great. Thank you 回答1: As deanWombourne said, you can use NSUserDefaults to store these data but it isn't very secure.

First of all, copy SFHFKeychainUtils files to your project. Click on the SFHFKeychainUtils.m and click on

问题 In my web app I need to give the user the option to save a js variable as a file (when the user clicks download, the app offers him to save a file, preffereably as .js file).
