ios – 崩溃CGImageDestinationFinalize

概述我的应用程序允许用户使用照片框架编辑照片.我看到一些崩溃报告,似乎在生成输出图像时发生崩溃,但我不知道问题所在.这种崩溃发生在多个硬件设备和多个版本的iOS 9,包括最新的9.1.我的应用程序最后一个调用是CG ImageDestinationFinalize,以创建编辑的图像NSData.崩溃报告显示,在出现崩溃发生在GLTextureManager之前,CoreImage空间中继续进行呼叫. 我的应用程序允许用户使用照片框架编辑照片.我看到一些崩溃报告,似乎在生成输出图像时发生崩溃,但我不知道问题所在.这种崩溃发生在多个硬件设备和多个版本的iOS 9,包括最新的9.1.我的应用程序最后一个调用是CG @L_419_0@DestinationFinalize,以创建编辑的图像NSData.崩溃报告显示,在出现崩溃发生在GLTextureManager之前,CoreImage空间中继续进行呼叫.

这可能是内存不足的问题吗？你看到这个问题吗？如何解决？

PhotoEditor.swift的相关代码,内部函数fullimageOutput,从editSingleAsset调用,后台队列中运行QOS_CLASS_UTIliTY：

let outputPhoto = //the generated CIImage that is the edited photo to be saved to disklet dataRef = CFDataCreateMutable(nil,0)if let destination = CGImageDestinationCreateWithData(dataRef,"public.jpeg",1,nil) {    struct ContextStruct {        static var ciContext: CIContext? = nil    }    if ContextStruct.ciContext == nil {        let eaglContext = EAGLContext(API: .OpenGLES2)        ContextStruct.ciContext = CIContext(EAGLContext: eaglContext)    }    let cgImage = ContextStruct.ciContext!.createCGImage(outputPhoto,fromrect: outputPhoto.extent)    CGImageDestinationAddImage(destination,cgImage,nil)    if CGImageDestinationFinalize(destination) { //FIXME: CRASH       //write to disk from dataRef etc    }}
