CrashDemo

自己写代码捕获异常信息,将捕获到的异常信息在下次联网的时候发给后

1)将UncaughtExceptionHandler1.h UncaughtExceptionHandler1.m 文件拖到项目中

2)AppDelegate.m 中

#import "UncaughtExceptionHandler1.h"

• (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. //调用这个函数就可以收集崩溃信息 InstallUncaughtExceptionHandler();

  return YES; }

3)ViewController.m中 [dict setObject:nil forKey:@"kong"];制造崩溃信息

• (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view, typically from a nib. NSMutableDictionary *dict = [NSMutableDictionary dictionary]; //这里打开就可以看到控制台输出异常信息 // [dict setObject:nil forKey:@"kong"]; }

4)异常信息输出
