捕捉崩溃路径方法的实现及介绍

AppDelegate.m

#import "AppDelegate.h"
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    //异常对象:NSException
    //参数：将函数的地址给它
    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
}

本次导致崩溃的地方

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”];//**因为这里是对不可变数组进行增加元素，所以会产生崩溃
}
@end
