I am using the 'analyze' tool in xcode to check for potential leakages in my app.

I am getting the following warning as a result.

How do I resolve the potential leak shown above? "self.answerArray" is just an array I declared in my header file

 

解决 :

You've called mutableCopy on the array (which returns a new array with a retain count of +1 - You own it), and you assign it to a property (which I assume is a strong/retain property) and you're not releasing it. You're leaking the memory.

You should release tempArray after assigning it to the property - and ensure the property is released in your class' dealloc method.

这个项目中遇到类似的问题

if (self.newsList) {
        for (int count = 0; count < [ self.newsList count]; count ++) {
            self.currentRecord = [ self.newsList objectAtIndex:count];
            if ([[[self.currentRecord .personVOList objectForKey:@"pk"] stringValue] isEqualToString:((KidsAppDelegate*)[[UIApplication sharedApplication]delegate]).currentKidPK]) {
                NSMutableArray * localArray = [((KidsAppDelegate*)[[UIApplication sharedApplication]delegate]).currentKidNewsList  mutableCopy];
                self.currentNewsList = localArray; //或者书写为

self.currentNewsList = [((KidsAppDelegate*)[[UIApplication sharedApplication]delegate]).currentKidNewsList  mutableCopy];

都会有以上的问题存在
                break;
                
            }
            
        }
        
    }
修改方式:

if (self.newsList) {
        for (int count = 0; count < [ self.newsList count]; count ++) {
            self.currentRecord = [ self.newsList objectAtIndex:count];
           
if ([[[self.currentRecord .personVOList objectForKey:@"pk"]
stringValue] isEqualToString:((KidsAppDelegate*)[[UIApplication
sharedApplication]delegate]).currentKidPK]) {
                NSMutableArray * localArray = [((KidsAppDelegate*)[[UIApplication sharedApplication]delegate]).currentKidNewsList  mutableCopy];
                self.currentNewsList = localArray; //或者书写为

[localArray release];或者

NSMutableArray * localArray = [[((KidsAppDelegate*)[[UIApplication sharedApplication]delegate]).currentKidNewsList  mutableCopy] autorelease];

break;
                
            }
            
        }
        
    }
