小编Ale*_*nte的帖子

我知道如何从中获取电话号码ABRecordRef,但我现在想要的是获取号码的类型,即其标签为字符串:

const CFStringRef kABPersonPhoneIPhoneLabel;
const CFStringRef kABPersonPhoneMainLabel;
const CFStringRef kABPersonPhoneHomeFAXLabel;
const CFStringRef kABPersonPhoneWorkFAXLabel;
const CFStringRef kABPersonPhonePagerLabel;

以下是我获取数字的方法:

//get all phone numbers                   
NSArray *phoneNumbersArray = (NSArray*)ABMultiValueCopyArrayOfAllValues(phoneNumberProperty);
NSInteger numbersCounter = 0;
for(numbersCounter = 0; numbersCounter < [phoneNumbersArray count]; numbersCounter++)
{
     NSString currentPhoneNumber = [phoneNumbersArray objectAtIndex:indexPhoneNumber];

      // here i would like to read the type of phone number 
      // NSLog(@"NumberType:%@",numberType);                    
 }

我尝试了各种各样的东西,我已经阅读了ABPerson参考资料,我不知道如何获得电话号码类型？

在我的项目中,我AVAudioSession用来检测任何耳机已插入或拔出.但在这种情况下,我无法检测何时插入蓝牙设备.这是我的耳机状态代码.

 - (void)audioRouteChangeListenerCallback:(NSNotification*)notification
    {

    NSDictionary *interuptionDict = notification.userInfo;

    NSInteger routeChangeReason = [[interuptionDict valueForKey:AVAudioSessionRouteChangeReasonKey] integerValue];

    switch (routeChangeReason) {

        case AVAudioSessionRouteChangeReasonNewDeviceAvailable:
            //NSLog(@"AVAudioSessionRouteChangeReasonNewDeviceAvailable");

            NSLog(@"Headphone/Line plugged in");

            [_soundButtonOutlet setImage:[UIImage imageNamed:@"sound-on.png"] forState:UIControlStateNormal];

            _headSetState=YES;

            break;

        case AVAudioSessionRouteChangeReasonOldDeviceUnavailable:
            NSLog(@"AVAudioSessionRouteChangeReasonOldDeviceUnavailable");

            NSLog(@"Headphone/Line was pulled. Stopping player....");

             [_soundButtonOutlet setImage:[UIImage imageNamed:@"sound-off.png"] forState:UIControlStateNormal];
            if(_isPlaying==YES)
            {


            [self.player pause];

            [_audioButtonOutlet setImage:[UIImage imageNamed:@"play.png"] forState:UIControlStateNormal];

            _isPlaying=NO;

            }
            _headSetState=NO;

            break;

        case AVAudioSessionRouteChangeReasonCategoryChange:
            // called at start - also when other audio wants to play
            NSLog(@"AVAudioSessionRouteChangeReasonCategoryChange");


            break;
    }

如何在iPhone应用程序中实现activesync协议？任何建议,任何文档和教程都很好.

我从apple上读过Exchange ActiveSync和iOS 4设备.这有什么真正的文档吗？

我正在使用ios 5和ARc启用.所以在下面的例子中我得到内存泄漏警告......但是因为使用ARC,我不能使用自动释放.有人建议吗？

  -(void)coreImageEffect{
    CIImage *inputImage = [[CIImage alloc] initWithImage:blurImage.image];
    CIFilter *hueAdjust = [CIFilter filterWithName:@"CIHueAdjust"];

    [hueAdjust setDefaults];
    [hueAdjust setValue:inputImage forKey:@"inputImage"];
    [hueAdjust setValue:[NSNumber numberWithFloat: 3.4f]
    forKey:@"inputAngle"];

    CIImage *outputImage = [hueAdjust valueForKey:@"outputImage"];
    CIContext *context = [CIContext contextWithOptions:nil];

    blurImage.image = [UIImage imageWithCGImage:
    [context createCGImage:outputImage
    fromRect:outputImage.extent]];

    }

我不能用[CIContext Autorelease]; 问题是显示CIContext"Method返回一个带有+1保留计数的核心基础对象"

请建议.
