NSArray 中的内存泄漏，跟踪很长时间

Question

下面的 self.listOfCustDetail 和 self.listOfCustomer 中存在内存泄漏

-(void) calCustList {
    NSArray   *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString  *documentsDirectory = [paths objectAtIndex:0];  
    NSString  *plistPath = [NSString stringWithFormat:@"%@/%@", documentsDirectory,@"customer.plist"];
    self.listOfCustDetail = [[[NSMutableArray alloc] init] autorelease];
    self.listOfCustomer = [[[NSMutableArray alloc] init] autorelease];
    self.customers =  [[[NSMutableDictionary alloc] initWithContentsOfFile:plistPath] autorelease];
    [self.listOfCustomer removeAllObjects];
    [self.listOfCustDetail removeAllObjects];
    [self.listOfCustomer addObject:@"新紀錄"];
    [self.listOfCustDetail addObject:@""];
    for (id key in self.customers) {
        NSString *s = [NSString stringWithFormat:@"%@,%@,%@,%@", [[self.customers objectForKey:key] objectAtIndex:0], [[self.customers objectForKey:key] objectAtIndex:1], [[self.customers objectForKey:key] objectAtIndex:2], [[self.customers objectForKey:key] objectAtIndex:3]];
        [self.listOfCustomer addObject:key];
        [self.listOfCustDetail addObject:s];
    }  
}

Answer 1

如何定义您的属性？ 他们保留吗？如果它们确实保留了，那么您正在显示的代码段中没有实际错误。

该方法多久调用一次？如果经常调用它，您可以使用自定义NSAutoreleasePool。

此外，新初始化的阵列上也不需要以下两行：

[self.listOfCustomer removeAllObjects];
[self.listOfCustDetail removeAllObjects];

您是否显示实际源代码？

建议，在项目中启用ARC（自动引用计数），因为您不需要释放数组
