Wenn der Benutzer erneut lädt, wird die Funktion erneut aufgerufen.

i erhalten mehrere Speicherlecks auf allen Saiten:

UPDATE dies der aktuelle Code ist.

vielleicht kann mir jemand dabei helfen.

Answer 1

Wo veröffentlichen Sie mixesArr?

Sie möchten auch alle Zeichenketten freigeben, die Sie behalten. Diese

Answer 2

if(mixesArr != nil) 
{ 
    [mixesArr removeAllObjects]; 
    [playListArr removeAllObjects]; 
} 

mixesArr = [[NSMutableArray alloc]init]; 

vorschlagen mixesArr konnte bereits zugeordnet werden, und man einfach eine neue Instanz zuordnen, so dass die ursprüngliche mixesArr ein baumelnden Zeiger.

Sollten Sie nicht schreiben etwas wie:

if(mixesArr != nil) 
{ 
    [mixesArr removeAllObjects]; 
    [playListArr removeAllObjects]; 
} 
else { 
    mixesArr = [[NSMutableArray alloc]init]; 
} 

oder etwas ähnliches?
