基于 ModalViewController 的应用程序在 30 次演示后崩溃
我有一个 ipad 应用程序，其中有类别（其中有 tableviewcontrollers）和详细视图，其中有一个 webview 显示 tableview 上的行信息。
在类别表视图的 didSelectRowAtIndexPath 函数上，我使用的代码为：
DetayViewController *dvc = [[DetayViewController alloc] init];
Blog *b = (Blog *)[self.blogArray objectAtIndex:indexPath.row];
dvc.cagirilanBlog = b;
[self presentModalViewController:dvc animated:YES];
这工作正常。但在使用该应用程序时，如果您单击表视图中的行并打开详细信息页面并关闭它大约 30 次，应用程序就会崩溃并退出。
应用程序崩溃时收到的警告如下：
**Received memory warning. Level=1**
**Received memory warning. Level=2**
**Program received signal: “0”.
Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib")**
当我关闭模式视图控制器时，我将释放在详细视图上使用的所有对象。但我无法解决的问题是为什么它会崩溃？这是一个错误吗？我不能使用presentModalViewController超过30次吗？
请帮我。
谢谢。
I have an ipad App, which has categories (tableviewcontrollers inside it) and detail views which has a webview shows info of the row on tableview.
On didSelectRowAtIndexPath function of category table views i am using the code as:
DetayViewController *dvc = [[DetayViewController alloc] init];
Blog *b = (Blog *)[self.blogArray objectAtIndex:indexPath.row];
dvc.cagirilanBlog = b;
[self presentModalViewController:dvc animated:YES];
This works fine. But when using the app, if you click row in table view and open a detail page and close it for about 30 times, the application crashes and quit.
The warnings i get when the app crashes is like:
**Received memory warning. Level=1**
**Received memory warning. Level=2**
**Program received signal: “0”.
Data Formatters temporarily unavailable, will re-try after a 'continue'. (Unknown error loading shared library "/Developer/usr/lib/libXcodeDebuggerSupport.dylib")**
When i dissmiss the modal view controller, i am releasing all the object i used on detail view. But the issue i can not solve is why is it crashing? is that a bug? Can not i use presentModalViewController more than 30 times?
Please help me.
Thanks.

您需要释放已使用的资源（每个内存分配都需要释放）。
在你的情况下：（
如果没有，你在 dealloc 方法中释放的所有对象都不会被调用！）
你还可以使用 Xcode 提供的 Leak 性能工具。 （对于检测内存泄漏非常有用）
您应该阅读此文档： http://developer.apple.com/library/ios/#documentation/cocoa/Conceptual/MemoryMgmt/MemoryMgmt.html
You need to release ressources that you have used (each memory allocations need to be released).
In your case :
(If not, all objets you have released in dealloc method won't be called !)
You can also use the Leak performance tool provided with Xcode. (very useful for detecting memory leaks)
