iphone - iOS 应用程序在启动时崩溃
<p><p>我的应用程序的最新版本已开始在某些用户启动时崩溃。 iTunes 中只有 1 个崩溃报告，如下所示。我无法在任何设备上重现。</p>
<p>两个版本的变化是</p>
<ol>
<li>集成了两个第三方库(iNotify、openUDID)</li>
<li>从 GCC 编译器切换到 Apple LLVM 3.1 编译器(新库需要 arc 支持)</li>
<li>在启用 arc 的情况下编译新库的代码，在项目的其余部分禁用 arc。</li>
</ol>
<p>我在 iNotify 的 appdelegate 中的 didFinishLaunchingWithOptions 中添加了 1 行。从堆栈跟踪到我认为它不会在那里崩溃。</p>
<p>有点不知所措。任何帮助，将不胜感激。谢谢!</p>

<p>一些额外的代码。</p>
<p>在appdelegate中有一个alertview定义如下:</p>
<pre><code>#import <UIKit/UIKit.h>
@class MyAPPViewController;
@interface MyAPPAppDelegate : NSObject <UIApplicationDelegate> {
UIViewController *rvc;
UIAlertView *m_cAlertControl;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
-(BOOL)shouldNag;
-(void)shouldEnableUI:(BOOL)pIsEnable;
-(void)updateRunCount;
@end
</code></pre>
<p>以及在应用委托(delegate)中实现的方法如下:</p>
<pre><code>-(void)shouldEnableUI:(BOOL)pIsEnable
{
if(NO == pIsEnable)
{
if (nil == m_cAlertControl) {
m_cAlertControl = [ init];
}
m_cAlertControl.backgroundColor = ;
m_cAlertControl.opaque = NO;
;
;
}
else {
if (nil != m_cAlertControl) {
;
}
}
</code></pre>
<p>}</p>
<p> ViewController 对方法的调用如下:</p>
<p>;</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>在看到崩溃日志问题时，似乎已在 <code>UIAlertViewDelegate</code> 发布后对其进行了调用。</p>
<p>您需要在使用警报的 Controller 中释放它 -</p>
<pre><code>-(void)dealloc {
self.alertView.delegate = nil; //setting delegate to nil
self.alertView = nil; //if you have defined alert as property
//other release statements of your controller
;
}
</code></pre>
<p>如果您想要一些其他信息，您可以添加您应用的一些代码，或者您的应用不是这样。</p>
<p>编辑 1 - </p>
<pre><code>-(void)dealloc {
m_cAlertControl.delegate = nil; //setting delegate to nil
;
//other release statements of your controller
;
}
</code></pre></p>
