Question

我在编译时遇到错误。

Undefined symbols for architecture armv6:
"_CGImageSourceCreateWithData", referenced from:
  ___-[AVCamCaptureManager captureStillImage]_block_invoke_1 in AVCamCaptureManager.o
"_CGImageSourceCopyPropertiesAtIndex", referenced from:
  ___-[AVCamCaptureManager captureStillImage]_block_invoke_1 in AVCamCaptureManager.o
ld: symbol(s) not found for architecture armv6
collect2: ld returned 1 exit status

它看起来像一个缺少的库，但我包括我认为我需要的那些，如

CoreGraphics中， QuartzCore Foundation.framework

我还在标题中添加了

#import <MobileCoreServices/UTCoreTypes.h>
#import <AssetsLibrary/AssetsLibrary.h>
#import <ImageIO/CGImageProperties.h>
#import <ImageIO/ImageIO.h>
#import <CoreFoundation/CoreFoundation.h>
#import <QuartzCore/QuartzCore.h>
#import <AVFoundation/AVFoundation.h>

我一直在追尾我40分钟，我想念的是什么？

非常感谢， -code

用于CGImageSourceCreateWithData

添加ImageIO.framework，

但是根据#import指令的外观我会说你还需要至少添加： AVFoundation和MobileCoreServices

与_CGImageSourceCreateWithData相关的链接错误
