ios - 为内存释放 UIImageViews

Question

我会多次调用这个方法:

-(void)entityMaker {
    UIImageView *entity;

    NSUInteger image = [self getRandomNumberBetween:0 to:1];
    NSUInteger xPosition = [self getRandomNumberBetween:20.0 to:self.width - 20.0];

    entity = [[UIImageView alloc] initWithFrame:CGRectMake(xPosition, 20, 20, 20)];
    [entity setImage:[self.imageArray objectAtIndex:image]];
    [self.view addSubview:entity];

    [self performSelector:@selector(animate:) withObject:entity afterDelay:2.0];
}

-(void)animate:(UIImageView *)image {
    [image release];
    //release has been deprecated 
}

但是，我不想让数百万张图片停留在屏幕上。

我怎样才能摆脱它们(在任何设定的秒数之后)，以便它们不再占用内存或不再显示？

如果您没有对 ImageView 的强引用(您在发布的代码中没有)，它将在您从其父 View 中删除后被释放。

-(void)animate:(UIImageView *)image {
    [image removeFromSuperview];
}
