iOS设置处理异常的方法

NSUncaughtExceptionHandler* _uncaughtExceptionHandler = nil;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    _uncaughtExceptionHandler = NSGetUncaughtExceptionHandler();
    // 设置处理异常的Handler
    NSSetUncaughtExceptionHandler(&uncaughtExceptionHandler);
}

void uncaughtExceptionHandler(NSException *exception) {
    if (exception) {
        NSArray *arr = [exception callStackSymbols];
        NSString *reason = [exception reason];
        NSString *name = [exception name];
        
        DDLogError(@"=============异常崩溃报告=============\nname:\n%@\nreason:\n%@\ncallStackSymbols:\n%@",
                   name,reason,[arr componentsJoinedByString:@"\n"]);
