When You check for memory leaks. At that time your app runs then only instrument can check for memory leaks. Click on the leaks and press record. It will run your app automatically if its selected in the apps drop down list in the instrument. If there will a leak then you will see a red spike in the leak chart. Presence of leak does not mean your app will crash. It will crash only when it will be running out of memory due to leaking memory repeatedly.
