当我点击链接框架上的“+”时找不到框架＆amp;图书馆

Question

当我点击链接框架上的'+'时，我找不到添加框架＆amp;库我想添加一个音频工具包框架和核心音频如何添加这两个框架。如果它们不在库中请帮帮我。

NSArray *pathComponents = [NSArray arrayWithObjects:
                               [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject],
                               @"MyAudioMemo.m4a",
                               nil];
    NSURL *outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];

    // Setup audio session
    AVAudioSession *session = [AVAudioSession sharedInstance];
    [session setCategory:AVAudioSessionCategoryPlayAndRecord error:nil];

    // Define the recorder setting
    NSMutableDictionary *recordSetting = [[NSMutableDictionary alloc] init];

    [recordSetting setValue:[NSNumber numberWithInt:kAudioFormatMPEG4AAC] forKey:AVFormatIDKey];
    [recordSetting setValue:[NSNumber numberWithFloat:44100.0] forKey:AVSampleRateKey];
    [recordSetting setValue:[NSNumber numberWithInt: 2] forKey:AVNumberOfChannelsKey];

// Initiate and prepare the recorder
recorder = [[AVAudioRecorder alloc] initWithURL:outputFileURL settings:recordSetting error:nil];
recorder.delegate = self;
recorder.meteringEnabled = YES;
[recorder prepareToRecord];

Answer 1

确保框架在路径../Developer/SDKs/iPhoneOS(version).sdk/System/Library/Frameworks/处可用，否则您必须重新安装SDK

Answer 2

请像这样检查 项目设置 - ＆gt;构建阶段 - ＆gt;将二进制文件与库链接

并确保添加有关AV基础工作的框架。
