How can I check iphone application for memory leaks?

Question

What methods / tools can I use to check for memory leaks in my iphone app? Or how to find and fix them?

Answer 1

Use the tools: first create and install the application on the simulator. Stop the process again (red screen where it says “task”), then go to “Run-> Run” using the “Efficiency” → “Leaks” tool. This will launch the Tools preconfigured using the Leakage and Memory Allocation tools. For more information, check out the Apple Memory Efficiency Guide (which also contains a section on leak detection): http://developer.apple.com/library/ios/#documentation/Performance/Conceptual/ManagingMemory/ManagingMemory.html

Answer 2

in xcode 5 just go to product -> analyze ... then look at the list of memory leaks . just go to the breakpoint and try to free them, no variables and class object are required ....

This tool tells you which library is leaking, and then you can debug your code as you wish. If it is well organized, you can immediately see which object is flowing and fix the problem with ease.

Answer 3

Why is it easy! Just run the leak performance tool. Click the following: Run → Start with Performance Tool → Leaks.

Good luck :)

Answer 4

You can try to use tools from Xcode, Leaks, CPU probe, Allocations, Activity monitor. They can be found in the Run-> Run menu with performance tools.

It would be ideal to have a device attached to your computer to run tools on top of an installed application.
