You can use this class to realize a simple sectioned grid RecyclerView.Adapter without changing your code.
The RecyclerView has to use a GridLayoutManager.

You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.
The RecyclerView should use a LinearLayoutManager.
You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

| This is the complete list that’s outputted by ffmpeg when running ffmpeg -h full. | |
| usage: ffmpeg [options] [[infile options] -i infile]… {[outfile options] outfile}… | |
| Getting help: | |
| -h — print basic options | |
| -h long — print more options | |
| -h full — print all options (including all format and codec specific options, very long) |

| // You have a very very large video file you need to upload to a server while your app is backgrounded. | |
| // Solve by using URLSession background functionality. I will here use Alamofire to enable multipart upload. | |
| class Networking { | |
| static let sharedInstance = Networking() | |
| public var sessionManager: Alamofire.SessionManager // most of your web service clients will call through sessionManager | |
| public var backgroundSessionManager: Alamofire.SessionManager // your web services you intend to keep running when the system backgrounds your app will use this | |
| private init() { | |
| self.sessionManager = Alamofire.SessionManager(configuration: URLSessionConfiguration.default) | |
| self.backgroundSessionManager = Alamofire.SessionManager(configuration: URLSessionConfiguration.background(withIdentifier: "com.lava.app.backgroundtransfer")) |
| Use: | |
| NSURLSessionConfiguration:backgroundSessionConfiguration: | |
| instead of | |
| NSURLSessionConfiguration:defaultSessionConfiguration | |
| From the NSURLSessionConfiguration:backgroundSessionConfiguration: documentation: | |
| Upload and download tasks in background sessions are performed by an external daemon instead of by the app itself. As a result, the transfers continue in the background even if the app is suspended, exits, or crashes. | |
| So in your case, change: |
| It should be use below code. | |
| dispatch_async(dispatch_get_main_queue(), ^{ | |
| [NSThread sleepUntilDate:[NSDate dateWithTimeIntervalSinceNow:10]]; | |
| self.alert.text = @"Thanks"; | |
| }); |
| With "atomic", the synthesized setter/getter will ensure that a whole value is always returned from the getter or set by the setter, regardless of setter activity on any other thread. That is, if thread A is in the middle of the getter while thread B calls the setter, an actual viable value -- an autoreleased object, most likely -- will be returned to the caller in A. | |
| In nonatomic, no such guarantees are made. Thus, nonatomic is considerably faster than "atomic". |
| actually there is no bug |
