日志记录
iOS日志记录当前文件的堆栈、类名、函数名、行号及文件路径等信息
NSArray *array = [NSThread callStackSymbols];
NSLog(@"堆栈信息： %@", array);

NSLog(@"当前函数名： %s", __func__);
NSLog(@"当前函数和参数： %s", __PRETTY_FUNCTION__);

异常捕获
主要是NSSetUncaughtExceptionHandler函数
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
// 关键函数：设置未捕获的异常处理器
NSSetUncaughtExceptionHandler(&getException);
return YES;
}
//获得异常的C函数
void getException(NSException *exception)
{
NSLog(@"名字：%@",exception.name);
NSLog(@"原因：%@",exception.reason);
NSLog(@"用户信息：%@",exception.userInfo);
NSLog(@"栈内存地址：%@",exception.callStackReturnAddresses);
NSLog(@"栈描述：%@",exception.callStackSymbols);
//每次启动的时候将，捕获的异常信息，反馈给服务器
//获取当前设备
UIDevice*divice=[UIDevice currentDevice];
//1.系统版本
NSString*systemVersion=divice.systemVersion;
//2.app当前版本
//先获取当前infoplist文件数据
NSDictionary*infoDic=[[NSBundle mainBundle] infoDictionary];
//然后从字典中取出版本号
NSString*version=[infoDic objectForKey:@"CFBundleShortVersionString"];
NSLog(@"系统版本%@",version);
//3.系统时间
NSDate*date=[NSDate date];
//4.设备种类
NSString*model=divice.model;
//将捕获的异常数据进行保存，保存到本地
//可以在下一次启动的时候将数据发给服务器
