IOS flashback protection strategy

Abstract

The invention relates to an iOS flashback protection strategy. The strategy includes the following steps of registering an abnormality monitoring signal for continuously capturing App abnormalities, using the abnormality monitoring signal as a global abnormality catcher, acquiring abnormal stack information when the App abnormalities are caught, parsing the abnormal stack information, writing parsed main information into a local resource file, wherein the main information includes at least call timing, stack information and a number of times of generating crash, and continuing to monitor and capture the App abnormalities. The strategy can acquire the APP abnormalities in time through abnormality monitoring, can obtain the detailed abnormal information as much as possible when continuous flashback is found, the method of using a hot patch is used for repairing, the normal operation of App is ensured as much as possible, occurrence of cases such as data corruption and the like is avoided, and the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of iOS flashback protection, in particular to an iOS flashback protection strategy. Background technique [0002] iOS App may sometimes encounter the desperate situation of crashing (program crash) at startup: every time the App is opened, it crashes, and the App cannot be used normally. There are many reasons for App crash, which can be roughly classified as follows: [0003] 1. Memory management error: It may be that the available memory is too low, the memory required by the App exceeds the limit of the device, and the App cannot run and the App crashes. Or memory leaks, the longer the program runs, the more memory it takes up, and eventually all the memory is used up, causing the entire system to crash. Or the use of unauthorized memory locations may also cause App crash. [0004] 2. Program logic errors: array out of bounds, stack overflow, concurrent operations, logic errors. For example: App adds ...

Problems solved by technology

[0003] 1. Memory management error: It may be that the available memory is too low, the memory required by the App exceeds the limit of the device, and the App cannot run, causing the App to crash

Or memory leaks, the longer the program runs, the more memory it takes up, and eventually all the memory is used up, causing the entire system to crash

Or the use of unauthorized memory locations may also cause App crash

[0004] 2. Program logic errors: array out of bounds, stack overflow, concurrent operations, logic errors

[0006] 4. Network factors: It may be that the network speed is not good enough to meet the fast response time required by the App, resulting in Appcrash

Or switching between different networks may also affect the stability of the app
