アナライズを無視する
Xcodeで静的解析してくれて非常に便利な反面、「それはわかってるからええねん！」と言う事があると思う。
わかっていても非常に気持ち悪い。
そういう時に「ここは解析しなくていいよ」と指示する方法。
#ifndef __clang_analyzer__ ...ここが解析されないようになる。 #endif // not __clang_analyzer__
こういう風に使う
#ifndef __clang_analyzer__
peakLevels = calloc (2, sizeof (AudioQueueLevelMeterState));
#endif // not __clang_analyzer__ うん、すっきり！

追記
他にも警告を出さないようにするコンパイラフラグ。これはGCCからあるのかな。
すべての警告を出さないようにするには"-Wall"
#pragma clang diagnostic push
#pragma GCC diagnostic ignored "-Wall"
char a = 'bc'; //
#pragma clang diagnostic pop この変数使われていませんよ！の警告を出さないようにするには"-Wunused"
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wunused"
char a = 'c'; //
#pragma clang diagnostic popcharに複数の文字が入っているよ！の警告をださないのが"-Wmultichar"
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wmultichar"
char a = 'bc'; //
#pragma clang diagnostic pop他には...これだけあるらしい。
