This library provides a tracker to track symbols when your app is running. It helps you to export the ordered symbols file which you can use in Build Settings → Link → Order File.

YCSymbolTracker is available through CocoaPods.

To install it, simply add the following line to your Podfile:

pod 'YCSymbolTracker'

If you want to track symbols of other static/dynamic libraries, you have to add more lines to your Podfile:

post_install do |installer|
    require './Pods/YCSymbolTracker/YCSymbolTracker/symbol_tracker.rb'
    symbol_tracker(installer)
end

To run the example project, clone the repo, and run pod install from the Example directory first.

#import <YCSymbolTracker/YCSymbolTracker.h>

NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"demo.order"];
[YCSymbolTracker exportSymbolsWithFilePath:filePath];

import YCSymbolTracker

let filePath = NSTemporaryDirectory().appending("/demo.order")
YCSymbolTracker.exportSymbols(filePath: filePath)

Once you export the file, the work is done. You can remove this library in Podfile, and run pod install .

YCSymbolTracker is available under the MIT license. See the LICENSE file for more info.

在进行二进制重排的时候，需要导出启动时调用循序的符号表。这个工具就是用来导出这个符号表的，拿到符号表后在Build Settings → Link → Order File 中配置导出的 xx.order 文件路径就可以了。

YCSymbolTracker 可以通过 CocoaPods 进行安装。

在Podfile中添加以下代码:

pod 'YCSymbolTracker'

如果需要跟踪其他三方库的符号，需要添加下面的代码:

post_install do |installer|
    require './Pods/YCSymbolTracker/YCSymbolTracker/symbol_tracker.rb'
    symbol_tracker(installer)
end

#import <YCSymbolTracker/YCSymbolTracker.h>

NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:@"demo.order"];
[YCSymbolTracker exportSymbolsWithFilePath:filePath];

import YCSymbolTracker

let filePath = NSTemporaryDirectory().appending("/demo.order")
YCSymbolTracker.exportSymbols(filePath: filePath)

导出文件之后，就可以把Podfile中相关的配置删掉了，然后执行 pod install 。
