NSTimer crash 26 | 27 | 3. Container crash（数组越界，插nil等） 28 | 29 | 4. NSString crash （字符串操作的crash） 30 | 31 | 5. NSNotification crash 32 | 33 | 6. KVO crash（譬如某一属性的多次侦听，或是忘记removeObserver 或是多次removeObserver导致的crash） 34 | 35 | 7. KVC crash 36 | 37 | ## 了解更多？ 38 | 39 | 因为公司产品比较多，用了一些bug统计，发现某些产品闪退率还不低，为了降低闪退率，于是有了这个crash保护小样。在写的过程也搜索了一下同类的案例，发现一个写得特别好的，且比较全面的产品，即网易开发的大白（Baymax），也做了比较详细的介绍：http://mp.weixin.qq.com/s/GFt7uqrKw7m3R3KrV43zIQ 。美中不足的是，他们没有开源。楼主实现的功能，该文档都有讲到，思路也基本一致，大家可以学习使用。我也将抽更多时间完善它。 40 | 41 | 42 | 43 | -------------------------------------------------------------------------------- /iOS/QYCrashProtector/QYCrashProtector/Info.plist: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | CFBundleDevelopmentRegion 6 | en 7 | CFBundleExecutable 8 | $(EXECUTABLE_NAME) 9 | CFBundleIdentifier 10 | $(PRODUCT_BUNDLE_IDENTIFIER) 11 | CFBundleInfoDictionaryVersion 12 | 6.0 13 | CFBundleName 14 | $(PRODUCT_NAME) 15 | CFBundlePackageType 16 | APPL 17 | CFBundleShortVersionString 18 | 1.0 19 | CFBundleVersion 20 | 1 21 | LSRequiresIPhoneOS 22 | 23 | UILaunchStoryboardName 24 | LaunchScreen 25 | UIRequiredDeviceCapabilities 26 | 27 | armv7 28 | 29 | UISupportedInterfaceOrientations 30 | 31 | UIInterfaceOrientationPortrait 32 | UIInterfaceOrientationLandscapeLeft 33 | UIInterfaceOrientationLandscapeRight 34 | 35 | 36 | 37 | -------------------------------------------------------------------------------- /iOS/QYCrashProtector/QYCrashProtector/Test.m: -------------------------------------------------------------------------------- 1 | // 2 | // Test.m 3 | // QYCrashProtector 4 | // 5 | // Created by Zhi Zhuang on 2017/9/13. 6 | // Copyright © 2017年 qiye.
