如何閱讀Xcode 6.1 Instruments .trace文件？

Question

我一直在試圖讀取.trace文件，我已經使用自定義工具模板生成：使用（樂器的Automator， 分配 ， 泄漏 ） 儀器 。

我在這個stackoverflow答案中找到的最好的幫助。 基本上， 作者創建了一個自定義的Objective-C程序（ Traced ）來讀取特定類型的Apples .trace文件（instrument： OpenGL ES Driver ）。 他的回答是面向XCode 4.6 。

該代碼仍適用於XCode 6.1 ，但跟蹤文件似乎略有改變。 您必須在.trace包中找到*.run.zip文件並解壓縮。 在解壓縮的文件夾中，您現在必須找到*.run文件。 .trace包中有幾個*.run.zip文件; 每個使用的儀器一個。

簡單地運行Traced程序讓我得到了一個uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** class error for 'XRObjectAllocRun' - 錯誤。

這個錯誤最初很容易搞清楚。 我所要做的就是實現缺少的類XRObjectAllocRun ; 與XRRun的示例XRRun或XRVideoCardRun類並行 。

這是我走了多遠，陷入困境的地方：

#import "XRObjectAllocRun.h"

@implementation XRObjectAllocRun
- (id)initWithCoder:(NSCoder *)decoder
{
    if((self = [super init]))
    {   
        NSObject *a = [decoder decodeObject];
        NSObject *b = [decoder decodeObject];
        NSObject *c = [decoder decodeObject];
        NSObject *d = [decoder decodeObject];
        NSObject *e = [decoder decodeObject];
        NSObject *f = [decoder decodeObject];
        NSObject *g = [decoder decodeObject];
        NSObject *h = [decoder decodeObject];
        NSObject *i = [decoder decodeObject];
//        NSObject *j = [decoder decodeObject];
//        NSObject *k = [decoder decodeObject];   
        NSLog(@"test");
    }
    return self;
}
@end

基本上我沒有對XRObjectAllocRun類進行逆向工程 。 但無論我解碼多少對象，我總會收到以下異常： uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** NSUnarchiver: inconsistency between written and read data for object 0x100112750'

如果取消注釋最后兩個decode語句，程序將因此異常而崩潰： uncaught exception 'NSArchiverArchiveInconsistency', reason: '*** file inconsistency: read 'i', expecting '@'' 。

有誰知道Apples XRObjectAllocRun類的簽名？ 此類用於分配工具。

任何幫助都會很棒！

更新

我玩Swift並翻譯整個*.trace -reader - 它失敗了完全相同的錯誤：

import Foundation
import Cocoa

@objc(XRObjectAllocRun)
class XRObjectAllocRun: NSObject {
    func initWithCoder(decoder:NSCoder){
        var x = decoder.decodeObject()
        // this is where things start breaking...
    }
}

@objc(XRRun)
class XRRun: NSObject {
    // to be implemented    
}

@objc(XRTrackSegment)
class XRTrackSegment: NSObject {
    func initWithCoder(decoder:NSCoder)->NSString{
        var a = decoder.decodeObject()?.integerValue
        var b = decoder.decodeObject()?.integerValue
        var c = decoder.decodeObject()?.integerValue
        var d = decoder.decodeObject()?.integerValue
        var e = decoder.decodeObject()

        return "test"
    }
}

@objc(PFTTrackSegment)
class PFTTrackSegment: NSObject {
    func initWithCoder(decoder:NSCoder){
        var a = decoder.decodeObject()?.integerValue
        var b = decoder.decodeObject()?.integerValue
        var c = decoder.decodeObject()?.integerValue
        var d = decoder.decodeObject()?.integerValue
        var e = decoder.decodeObject()?.integerValue
        var f = decoder.decodeObject()?.integerValue
    }
}

// parse command line
var traceFilePath = Process.arguments[1]
println("input: \(traceFilePath)")

var traceFile = NSURL(fileURLWithPath: traceFilePath)
var error:NSError?

// check if the file exists
if (traceFile?.checkResourceIsReachableAndReturnError(&error) == false){
    // file does not exist or cannot be accessed
    println("\(error)")
    exit(1)
}

var rawData = NSData(contentsOfURL: traceFile!)
var data = NSUnarchiver(forReadingWithData: rawData!)
var decodedObject: AnyObject? = data?.decodeObject()
println("\(decodedObject)")

如果你需要，我已經在這里上傳了其他課程的簽名。

您可以簡單地將存檔中的標頭導入到橋接標頭，而不是在Swift中聲明所需的類。

我做到了。 這是git項目。
