我需要为youtube集成安装cocoapods,我使用此链接http://www.raywenderlich.com/64546/introduction-to-cocoapods-2作为参考

这是我的podfile

               //////////////////////////////////////////
# Uncomment this line to define a global platform for your project

target 'testyoutube' do

pod "YouTube-Player-iOS-Helper", "~> 0.1"

end

target 'testyoutubeTests' do

end

                //////////////////////////////////////////

当我试图安装pod时,我收到此错误代码

Ansals-Mac-mini:testyoutube ansalantony$ pod install
Analyzing dependencies

如何选择表视图的搜索结果而不是加载普通的表视图内容

在我的iOS项目中使用UISearchBar.搜索对我来说很好,但在选择搜索结果行的时候,选择行方法加载原始项而不是搜索结果行.我应该使用什么方法来加载结果行及其相应的详细信息页面.

谢谢,

     [self filterContentForSearchText:searchString scope:
     [[self.searchDisplayController.searchBar scopeButtonTitles] objectAtIndex:      
     [self.searchDisplayController.searchBar selectedScopeButtonIndex]]];    

     // Return YES to cause the search result table view to be reloaded.
     return YES;
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
     [self performSegueWithIdentifier:@"SubCategory" sender:self];
}      

#pragma mark Content Filtering
- (void)filterContentForSearchText:(NSString*)searchText scope:(NSString*)scope {

    // Remove all …

因为我对Xamarin World 非常陌生并且对其控件不熟悉.我想在我的单声道触摸应用程序中添加Circles to Show Work Progress.为了显示进度,我必须在圆圈中标记一个圆弧.如果可能,任何人都可以帮我一个示例代码.等待回答,非常感谢提前.

我想使用swift在我的应用程序中包含蓝牙功能.我想列出所有附近/可发现的外围设备,包括那些已经配对的设备

我应该使用哪种方法列出配对设备.我使用CoreBlutooth框架来实现蓝牙可用性检查.如果蓝牙工作正常,我想列出配对设备.如果可能,请提供直接从列出的配对设备连接设备的方法

 func startUpCentralManager() {
    println("Initializing central manager")
    centralManager = CBCentralManager(delegate: self, queue: nil)


}



func centralManagerDidUpdateState(central: CBCentralManager!) {
    println("\(__LINE__) \(__FUNCTION__)")
     println("checking state")

    if central.state != .PoweredOn {
        // In a real app, you'd deal with all the states correctly
                    return
    }
    central.scanForPeripheralsWithServices(nil,options:nil)


}

//此方法未触发

  func centralManager(central: CBCentralManager!, didDiscoverPeripheral peripheral: CBPeripheral!, advertisementData: [NSObject : AnyObject]!, RSSI: NSNumber!) {

    var localname: NSString = advertisementData[CBAdvertisementDataLocalNameKey]! as NSString

    println("Discovered\(peripheral.name)")

    if localname != " "
