Confusion about the Memory Use of Xcode,the Real Memory of Activity Monitor
<p>I would like to test APP in the process of running the physical memory occupied, the first way is to use xcode debugging APP, Memory Report shows real-time occupied physical memory, <strong>only about 90 MB</strong>; The second way to use Activity Monitor detection APP, In the Detail-> Summary-> Samples Real Memory display <strong>up to 200MB or so</strong>.
So I am confused, which value can really represent APP physical memory occupied?</p>
