捕捉崩潰路徑方法的實現及介紹

AppDelegate.m

#import "AppDelegate.h" @interface AppDelegate () @end @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //異常對象:NSException //參數：將函數的地址給它 NSSetUncaughtExceptionHandler(&getException); return YES; } //得到異常的C函數 void getException(NSException *exception) { NSLog(@"名字：%@",exception.name); NSLog(@"緣由：%@",exception.reason); NSLog(@"用戶信息：%@",exception.userInfo); NSLog(@"棧內存地址：%@",exception.callStackReturnAddresses); NSLog(@"棧描述：%@",exception.callStackSymbols); //每次啓動的時候將，捕獲的異常信息，反饋給服務器 //獲取當前設備 UIDevice*divice=[UIDevice currentDevice]; //1.系統版本 NSString*systemVersion=divice.systemVersion; //2.app當前版本 //先獲取當前infoplist文件數據 NSDictionary*infoDic=[[NSBundle mainBundle] infoDictionary]; //而後從字典中取出版本號 NSString*version=[infoDic objectForKey:@"CFBundleShortVersionString"]; NSLog(@"系統版本%@",version); //3.系統時間 NSDate*date=[NSDate date]; //4.設備種類 NSString*model=divice.model; //將捕獲的異常數據進行保存，保存到本地 //能夠在下一次啓動的時候將數據發給服務器 } 

本次致使崩潰的地方

ViewController.m

#import "ViewController.h" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; NSArray*arr=[[NSArray alloc]init]; NSMutableArray*mArr=(NSMutableArray*)arr; [mArr addObject:@「1」];//**由於這裏是對不可變數組進行增長元素，因此會產生崩潰 } @end
