you should never ignore memory leaks, its easy to avoid for the most part, its also what is giving ios developers a black eye.. make sure you release objects before allocating new ones. if you aren't sure how to do that then use arc in the latest xcode. which apple had to put in place because of all the bad apps that had major memory leaks.

if your app crashes to much because of memory leaks, or crashes for any reason, you'll get a lot of bad reviews, which will really hurt sales. i know it seems insignificant, but people still run apps with older devices some even jailbreak, so they can update to newer os's then is supported for that device and such..

Cheers,

How do you check for memory leaks? Sorry if thats abit vague, I'm relatively new to programming and didn't even know what a memory leak was, I've just googled it and am now interested to see if I have any memory leaks in a few little apps I've created... I guess it would be a good way of seeing if I am coding efficiently... Thank you!

I too would like to know Halley? What did you use?

Might be a good way of tracking bugs in AppGameKit as well as our own code...

Are we talking about Tier 2 here? Because I didn't think memory leaks were possible in Tier 1 unless there is an error in the AppGameKit player in which case there isn't much we can do about it.

I'm 99% sure we are. The above looks like it's out of Xcode or atleast a tool for iOS/Mac.

Halley does indeed code in tier 2, yes.

My signature is NOT a moderator plaything! Stop changing it!

The instruments which I use is a tool of Xcode. It's in the same file folder with Xcode 4.2.Analyze memory leaks is just one function of the tool, there are many functions, such as memory allocation, memory leaks, cpu usage, battery consume speed, wifi usage and so on, all aspects about application in the iOS platform.

But I don't know how to fix the memory leaks ,because I can't locate the position in my project.

@Deion, Thank you. I'll pay attention to it.

Hello Halley

The only way, for me, is to analyze yourself 'by hand' the source files paying special attention to the objects, if you use, and monitoring that are used and destroyed.

You also have to monitor that if you load any resource, it have to be destroyed after use. It is very easy to overlook this. Especially the resources called several times. It will gradually consume memory if they are not deleted after the call or the use. And if possible, leave the program with a return value of 0.

Among other things.

However, if it is a small app and of short duration, is not a major problem if the memory consumption is not great. At the end of the app the system must clear the memory. (must)

Regards
