iPhone/iPad App Code Obfuscation - Is it Possible? Worth it? [closed]

由 爱⌒轻易说出口 提交于 2019-11-27 02:31:44
I've researched quite a bit, both on SO, as well google-ing all over the place, but I can't seem to find a straight-forward answer in regards to code obfuscation for iPhone/iPad apps written in Objective-C. My questions are these: Is there a way to do it? If so, how? Is it worth it? Does Apple allow it, or have a problem with it, when the app is submitted to them? There doesn't seem to a code obfuscator for Objective-C. But let's assume for a moment that one does exist. Apple will probably not reject an obfuscated app as long as it doesn't crash. The main question is: what is the point of

Using SQL Server as Image store

由 我的梦境 提交于 2019-11-27 01:49:29
问题 Is SQL Server 2008 a good option to use as an image store for an e-commerce website? It would be used to store product images of various sizes and angles. A web server would output those images, reading the table by a clustered ID. The total image size would be around 10 GB, but will need to scale. I see a lot of benefits over using the file system, but I am worried that SQL server, not having an O(1) lookup, is not the best solution, given that the site has a lot of traffic. Would that even

Bash script store command output into variable

由 只谈情不闲聊 提交于 2019-11-27 00:40:19
问题 I have a problem concerning storing the output of a command inside a variable within a bash script. I know in general there are two ways to do this either foo=$(bar) # or foo=`bar` but for the Java version query, this doesn't seem to work. I did: version=$(java --version) This doesn't store the value inside the var. It even still prints it, which really shouldn't be the case. I also tried redirecting output to a file but this also fails. 回答1: version=$(java -version 2>&1) The version param

how to handle session expire basing redis?

由 一曲冷凌霜 提交于 2019-11-26 22:34:49
问题 I want to implement a session store based on Redis. I would like to put session data into Redis. But I don't know how to handle session-expire. I can loop through all the redis keys (sessionid) and evaluate the last access time and max idle time, thus I need to load all the keys into the client, and there may be 1000m session keys and may lead to very poor I/O performances. I want to let Redis manage the expire, but there are no listener or callback when the key expire, so it is impossible to

Creating a JSON Store For iPhone

由 余生长醉 提交于 2019-11-26 20:14:24
We have loads of apps where we fetch data from remote web services as JSON and then use a parser to translate that into a Core-Data model. For one of our apps, I'm thinking we should do something different. This app has read-only data , which is volatile and therefore not cached locally for very long . The JSON is deeply hierarchal with tons of nested "objects" . Documents usually contain no more than 20 top level items, but could be up to 100K. I don't think I want to create a Core Data model with 100's of entities, and then use a mapper to import the JSON into it. It's seems like such a song

How are integers internally represented at a bit level in Java?

由 偶尔善良 提交于 2019-11-26 02:05:19
问题 I am trying to understand how Java stores integer internally. I know all java primitive integers are signed, (except short?). That means one less bit available in a byte for the number. My question is, are all integers (positive and negative) stored as two\'s complement or are only negative numbers in two\'s complement? I see that the specs says x bit two\'s complement number . But I often get confused. For instance: int x = 15; // Stored as binary as is? 00000000 00000000 00000000 00001111?

How to reset the state of a Redux store?

由 别说谁变了你拦得住时间么 提交于 2019-11-26 00:17:14
问题 I am using Redux for state management. How do I reset the store to its initial state? For example, let’s say I have two user accounts ( u1 and u2 ). Imagine the following sequence of events: User u1 logs into the app and does something, so we cache some data in the store. User u1 logs out. User u2 logs into the app without refreshing the browser. At this point, the cached data will be associated with u1 , and I would like to clean it up. How can I reset the Redux store to its initial state
