what is the best way for saving username and High Score

由 为君一笑 提交于 2019-12-01 13:38:34
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 As deanWombourne said, you can use NSUserDefaults to store these data but it isn't very secure. If you don't want to store this data "in the air", you can take a look to SFHFKeychainUtils by Buzz Andersen to store them in the iPhone Keychain. First of all, copy SFHFKeychainUtils files to your project. Click on the SFHFKeychainUtils.m and click on Get Info. Go to Target tab and check if the box near your target is checked. If not, check it. Control-click

PHP Pass File Handle to user so that file downloads & saves to their machine

由 [亡魂溺海] 提交于 2019-12-01 13:23:29
问题 I am downloading a file from another server. I wish to push this file to my users rather than saving it to my server. In other words, pass them the file handle so it just passes through my server and saves to their machine. How can I do this? I have this so far: $handle = fopen($_GET['fileURL'], 'r'); $filename = stream_get_contents($handle); How do I push this to the user, maybe using headers? Thank you for any help and direction. EDIT I have the headers: header("Pragma: public"); //

How to save data , in an iOS application?

问题 I am developing an application where the user creates an event which has 3 fields: Category , name , event. After the user gives his entry , i have a save button that will save his data for future reference. Then when he opens the app again the data will be shown in a table View. How exactly do i "save" data on iOS ? I know about the NSUserDefaults , but i am pretty sure this is not the way for this example. What i ve done so far : I created a "Note" class with Category , name , event. The

Write a “string” as raw binary into a file Python

由 家住魔仙堡 提交于 2019-12-01 12:52:06
I'm trying to write a series of files for testing that I am building from scratch. The output of the data payload builder is of type string, and I'm struggling to get the string written directly to the file. The payload builder only uses hex values, and simply adds a byte for each iteration. The 'write' functions I have tried all either fall over the writing of strings, or write the ASCII code for the string, rather than the string its self... I want to end up with a series of files - with the same filename as the data payload (e.g. file ff.txt contains the byte 0xff def doMakeData(counter):

问题 I'm trying to replicate a UI effect as on http://mcfc.co.uk I have written a script that hides a div on click function and applies a class to a div with the #id corresponding to the div that was clicked, and the reverse.

Thanks for any help. <script type="text/javascript"> $(document).ready(function(){ $('.portlet').click( function(){ var idtext = this.id; $(this).hide(); $("[id*=

Why do not all started applications save the wanted information in the text files as expected?

I am trying to create a batch file on a USB drive that will run an .exe, save its text to a .txt file, and then close the .exe. I am currently running into a weird problem, only 5 of the 18 .exe's are actually saving their text to a file. This is the convention I am using to complete my task: start IEPassView.exe /stext Results/IEPassView.txt taskkill /f /im IEPassView.exe start MailPassView.exe /stext Results/MailPassView.txt taskkill /f /im MailPassView.exe start MessenPass.exe /stext Results/MessenPass.txt taskkill /f /im MessenPass.exe start RouterPassView.exe /stext Results/RouterPassView

I'm very new to this topic and trying to gain some understanding. I'm writing an application that allows user to personalize it and create his/own preferences, such as font color, size, certain nodes' positions and etc. While doing my research, I found couple examples using xml files to store users' perferenace. Is this the best way to store information? Is there a more secure way to do it? since xml file is readable for people and not just the machine. If you need to save more user informations, you can use a database. But if you need to save one user information, you can use Preferences :

Possible Duplicate: Is it possible to copy database file to SD card? I have a database on my Android phone, and I need to get the information onto an SD card. Is it possible to save the database file onto the SD card in a readable state? I haven't been able to find any information on how to do this. I know the name of the database, and fields etc... I've found some examples that show how to save to SD cards, but not exactly what I need. Some source code that copies the database file to an SD card would be perfect. Hopefully this question is clear enough. Yes. Here is the function that i use:

Print or capturing multiple objects in R

I have multiple regressions in an R script and want to append the regression summaries to a single text file output. I know I can use the following code to do this for one regression summary, but how would I do this for multiple? rpt1 <- summary(fit) capture.output(rpt1, file = "results.txt") I would prefer not to have to use this multiple times in the same script (for rpt1, rpt2, etc.), and thus have separate text files for each result. I'm sure this is easy, but I'm still learning the R ropes. Any ideas? You can store the result as a list and then use the capture.output fit1<-lm(mpg~cyl,data
