<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>可以肯定的是，您应该尝试从设备中获取崩溃日志。测试人员必须将设备与 iTunes 同步，然后导航到 iTunes 复制任何崩溃报告的文件夹。这取决于您使用的平台。</p>
<pre><code>Mac OS X: ~/Library/Logs/CrashReporter/MobileDevice/<DEVICE_NAME>
Windows XP: C:\Documents and Settings\<USERNAME>\Application Data\Apple Computer\Logs\CrashReporter\MobileDevice\<DEVICE_NAME>
Windows Vista or 7: C:\Users\<USERNAME>\AppData\Roaming\Apple Computer\Logs\CrashReporter\MobileDevice\<DEVICE_NAME>
</code></pre>
<p><code><USERNAME></code> 是计算机的用户登录名。 <code><DEVICE_NAME></code> 是 iPod touch 或 iPhone 的名称，例如“我的 iPhone”。</p>
<p>有一些方法可以自动收集崩溃报告，我在此处发布了有关可能性的概述，作为另一个答案的一部分:<a href="https://stackoverflow.com/questions/8488894/including-custom-data-into-ios-crash-dumps/8511100#8511100" rel="noreferrer noopener nofollow">Including custom data into iOS crash dumps</a> </p>
<p>此外，您可以在 iOS 模拟器中进行测试时自动发出内存警告。子类 <code>UIViewController</code> 并在 ViewController 出现时自动触发内存警告。</p>
<p>下面是一些关于如何做到这一点的示例代码:</p>
<pre><code>#import "BaseViewController.h"
@interface BaseViewController (Private)
- (void)simulateMemoryWarning;
@end
@implementation BaseViewController
- (void) viewDidAppear:(BOOL)animated {
;
#if TARGET_IPHONE_SIMULATOR
#if defined (CONFIGURATION_Debug)
// If we are running in the simulator and it's the DEBUG target
// then simulate a memory warning. Note that the DEBUG flag isn't
// defined by default. To define it add this Preprocessor Macro for
// the Debug target: DEBUG=1
;
#endif
#endif
}
- (void)simulateMemoryWarning {
#if TARGET_IPHONE_SIMULATOR
#if defined (CONFIGURATION_Debug)
SEL memoryWarningSel = @selector(_performMemoryWarning);
if ([ respondsToSelector:memoryWarningSel]) {
[ performSelector:memoryWarningSel];
} else {
NSLog(@"%@",@"Whoops UIApplication no loger responds to -_performMemoryWarning");
}
(CFStringRef)@"UISimulatedMemoryWarningNotification", NULL, NULL, true);
#endif
#endif
}
@end
</code></pre>
<p>现在在子类化您自己的 ViewController 而不是从 UIViewController 子类化时使用它。此代码最初发布在这里 <a href="https://gist.github.com/956403" rel="noreferrer noopener nofollow">https://gist.github.com/956403</a>并通过从此处添加解决方案来调整以使用 Xcode 4.2.1 <a href="https://stackoverflow.com/a/2785175/474794" rel="noreferrer noopener nofollow">https://stackoverflow.com/a/2785175/474794</a> </p></p>
