objective-c – 如何修复内存泄漏？

以下事项会增加保留计数

> [[alloc] init]
>新的
>复制
> [保留]
>将对象添加到数组中
>将对象添加为子对象(例如视图)
>可能还有更多,但您似乎没有在代码中使用任何其他内容

以下减少了保留计数

> [发布]
>从数组中删除对象
>如果你释放一个数组,它的所有对象都会被释放

您应该检查代码并确保数组的每个保留或添加都与相应的版本匹配. (您可以在dealloc方法中释放成员变量).

编辑：杰里米提出了一个有效的观点,我的答案没有

Once you add an object to an array,it takes ownership and will release the object when it is done with it. All you need to do is make sure you release anything you own according to the memory management rules

还有自动释放对象,看看这个例子;

-(init){
    ...
    stagePickerArray = [[NSMutableArray alloc] init];
    for (int i = 0; i < 3; i++)
    {
        //this string is autoreleased,you don't have call release on it.
        //methods with the format [CLASS CLASSwithsomething] tend to be autorelease
        NSString *s = [NSString stringWithFormat:@"%d",i);
        [stagePickerArray addObject:s];
    }
    ...
 }

我认为你唯一缺少的就是在你的dealloc方法中调用release

-(void) dealloc
{
    [stagepickerarray release];  //Do this for each of your arrays
    [super dealloc];
}
