小编Ben*_*lon的帖子

我想检测用户何时拒绝我的iOS应用程序上的麦克风权限.我在尝试录制麦克风时只获得此值:-120.000000 db

但在此之前我必须设置一个AVAudioSession.还有其他功能吗？

我在输出中得到了这条消息: Microphone input permission refused - will record only silence

谢谢.

可能重复:
全局int变量目标c

我想创建一个全局变量.我想在任何地方访问这个变量.

Java等价物:

static var score:int = 0;

例如,如果我将全局变量定义到Game类中.如何访问这个全局变量？

Game.score ?

我测试了Xcode 7,但我的cocos2d 2.1游戏在模拟器或设备上崩溃:

ccShader_PositionColorLenghtTexture_frag.h

和

cocos2d: ERROR: 0:26: Invalid call of undeclared identifier 'fwidth'

这堂课让游戏崩溃了

当我从svn版本控件上的projet中使用finder删除文件或文件夹时,我总是收到警告:

file://localhost/Users/XXX/Documents/Projets/XXX/file.jpg:警告:缺少文件:工作副本中缺少/Users/XXX/Documents/Projets/XXX/file.jpg

如何正确删除文件？该文件未显示在项目导航器上.

谢谢.

我的应用程序使用SLComposeViewController发布到Twitter.这工作了几个月,然后大约一个星期前突然停止了.Twitter共享视​​图允许我按"发布",以下代码仍然到达"..."行:

    twitterComposeViewController.completionHandler =
^(SLComposeViewControllerResult result){
        if (result == SLComposeViewControllerResultDone){
            ...
        }
    };

并且驳回了Twitter分享视图,但推文失败了.我得到一个警告视图说,

无法发送推文

无法发送推文"[我的推文文本]",因为与Twitter的连接失败.

片刻之后,控制台记录,

插件com.apple.share.Twitter.post无效

我在SO上看了一些类似的问题,但没有一个有适用的答案(我的推文没有超过字符限制;我已正确登录;等等).我在apps.twitter.com检查了我的设置,我没有看到任何异常...我的消费者密钥和秘密没有改变......

任何人都知道如何获得有关错误的更多信息,或者我应该检查什么？谢谢.

我在MKStoreKit 5上发生了这个错误.我在所有MKStoreKit文件上添加了-objc-arc标志,但是我收到了这个错误.

我想从iOS开发门户重置设备列表.

但是,当我单击继续按钮时,我收到此错误:发生了一个未指定的错误.请刷新并重试.

我正在使用CoreBluetooth,但我在输出中收到了此警告消息.

CoreBluetooth [WARNING]没有恢复标识符,但委托实现了centralManager:willRestoreState:方法.不支持恢复!

我正在使用此代码:

NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:NO], CBCentralManagerOptionShowPowerAlertKey, nil];

myCentralManager = [[CBCentralManager alloc] initWithDelegate:self queue:nil options:options];

我不知道出了什么问题.

谢谢.

我用AVCaptureSession拍摄视频.但我想将捕获的图像转换为UIImage.

我在互联网上找到了一些代码:

    // Get a CMSampleBuffer's Core Video image buffer for the media data
    CVImageBufferRef imageBuffer = CMSampleBufferGetImageBuffer(sampleBuffer);
    // Lock the base address of the pixel buffer
    CVPixelBufferLockBaseAddress(imageBuffer, 0);

    // Get the number of bytes per row for the pixel buffer
    void *baseAddress = CVPixelBufferGetBaseAddress(imageBuffer);

    // Get the number of bytes per row for the pixel buffer
    size_t bytesPerRow = CVPixelBufferGetBytesPerRow(imageBuffer);
    // Get the pixel buffer width and height
    size_t width = …
