我已将此代码用作UncaughtExceptionHandler我的应用程序来捕获一些崩溃信息并将其返回给我：
NSArray *callStack = [exception callStackReturnAddresses];
int i,len = [callStack count];
// void **frames = new void *[len];
void **frames = (void**)malloc(len);
for (i = 0; i < len; ++i) {
frames[i] = (void *)[[callStack objectAtIndex:i] unsignedIntegerValue];
}
char **symbols = backtrace_symbols(frames,len);
/*
* Now format into a message for sending to the user
*/
NSMutableString *buffer = [[NSMutableString alloc] initWithCapacity:4096];
NSBundle *bundle = [NSBundle mainBundle];
[buffer appendFormat:@"Version %@\n\n",[bundle objectForInfoDictionaryKey:@"CFBundleVersion"]];
[buffer appendFormat:@"Device: %@. OS: %@\n", [[UIDevice currentDevice] model], [[UIDevice currentDevice] systemVersion]];
[buffer appendString:@"Uncaught Exception\n"];
[buffer appendFormat:@"Exception Name: %@\n",[exception name]];
[buffer appendFormat:@"Exception Reason: %@\n",[exception reason]];
[buffer appendString:@"Stack trace:\n\n"];
for (i = 0; i < len; ++i) {
[buffer appendFormat:@"%4d - %s\n",i,symbols[i]];
}
今天，我收到了一份崩溃报告，与您从 iTunes Connect 获得的报告相比，该报告非常少。它看起来像这样：

我使用 atos 来表示报告中的内存地址，但是 3 个地址0x0013f1f1 0x001285ed 0x0012887d只是返回__PRETTY_FUNCTION__.20480 (in myapp) + 101235 __PRETTY_FUNCTION__.20480 (in myapp) + 8047 __PRETTY_FUNCTION__.20480 (in myapp) + 8703，这对我没有帮助。我还能做些什么来至少找到导致崩溃的方法名称吗？
如果没有，有什么我可以添加到我的UncaughtExceptionHandler或在将来的版本中为我提供方法名称的东西吗？我似乎从未收到任何 iTunes Connect 崩溃报告，这就是我选择这条路线的原因。
谢谢
