关于iphone：在哪里解除pickerview？

Where to dealloc pickerview?

在模态视图中，我有一个在 viewDidLoad.

中分配和初始化的 UIPickerView

它在 dealloc 中与此视图中使用的其他对象一起被释放。

这是释放我的选择器的错误方式吗？为什么在模式视图被关闭后需要访问它，因为错误消息似乎在暗示？

僵尸日志错误是：

1	-[UIPickerView release]: message sent to deallocated instance 0x5a441

//navigation bar stuff here

mcPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 244, 320, 216)];
mcPickerView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;

// setup the data source and delegate for this picker
mcPickerDataSource = [[MCPickerDataSource alloc] init];
