1、背景
原生代码不像前端，可以无感更新，当线上出现致命问题时，如果没有做ABTest或者其他远程配置，往往需要通过发版才能解决，而原生发版需要经过应该市场审核，往往流程长（一般需要12小时，甚至24小时以上）。
2、技术方案
JSPatch方案被AppStore拒了，只能转向寻求二进制化的热更新方案
OCRunner,通过编译二进制补丁，理论上是可以通过AppStore审核（待后续尝试一下）
3、实践步骤

git clone --recursive https://github.com/SilverFruity/OCRunner.git
详细介绍可参考：https://github.com/SilverFruity/OCRunner/blob/master/README-CN.md
先制造一段崩溃代码：

+ (void)willCrash
{
NSLog(@"TestCrash will crash");
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
NSArray *a = @[];
a[0];
NSLog(@"TestCrash do not crash");
});
}
在调用上述代码后，会崩溃，崩溃日志如下：

NSLog(@"PSCTestCrash will crash");
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
NSArray *a = @[];
NSLog(@"PSCTestCrash crashing 1");
NSLog(@"PSCTestCrash crashing 2");
NSLog(@"PSCTestCrash crashing 3");
//去掉崩溃代码后
// a[0];
NSLog(@"PSCTestCrash do not crash");
});
执行编译二进制修复文件：
1
./PatchGenerator -files PSCTestCrash.m -refs Scripts.bundle -output binarypatch
