53 | [[FFManager sharedInstance] startWorkWithOption:FFHookOptionAll unrecogziedSelectorClassPrefixs:@[@"SSZ"] callBackBlock:^(NSDictionary *exceptionDic) { 54 | [weakSelf reportExecptionToBugly:exceptionDic]; 55 | }]; 56 | ``` 57 | 58 | 如上所述，传入@"SSZ"则可以保护所有以 SSZ 开头的类，避免 `unrecognized selector sent to instance` 这个类型的崩溃。 59 | 60 | 61 | 62 | just like this: 63 | 64 | ```objective-c 65 | #pragma mark - Report Exception To Bugly 66 | - (void)reportExecptionToBugly:(NSDictionary *)exceptionDic 67 | { 68 | if (exceptionDic) { 69 | NSString *name = [exceptionDic objectForKey:FF_Name]; 70 | NSString *reason = [exceptionDic objectForKey:FF_Reason]; 71 | NSDictionary *extraDic = [exceptionDic objectForKey:FF_ExtraDic]; 72 | NSArray *callStack = [exceptionDic objectForKey:FF_CallStackSymbols]; 73 | 74 | [Bugly reportExceptionWithCategory:3 name:name reason:reason callStack:callStack extraInfo:extraDic terminateApp:NO]; 75 | } 76 | } 77 | ``` 78 | 79 | 80 | 81 | `Tips`: classPrefixs is your own calsses that you want to avoid `unrecogzied selector sent to instance ` crash. 82 | 83 | ```objective-c 84 | - (void)startWorkWithOption:(FFHookOption)option unrecogziedSelectorClassPrefixs:(NSArray *)classPrefixs callBackBlock:(FFExceptionBlock)block; 85 | ``` 86 | 87 | 88 | 89 | --- 90 | 91 | 92 | 93 | Safe method for example 94 | 95 | **NSArray** 96 | 97 | ```objective-c 98 | - (BOOL)writeToURL:(NSURL *)url error:(NSError * _Nullable __autoreleasing *)error;
