JSGCDDispatcher, a small Objective-C wrapper around GCD

JSGCDDipatcher is a small Objective-C wrapper around GCD that provides a simple interface to submit blocks to GCD either on the serial or concurrent queue.

Global Queue

[[JSGCDDipatcher sharedDispatcher] dispatch:^{
  // Busy Work
}];

[[JSGCDDipatcher sharedDispatcher] dispatch:^{
  // Busy Work
} priority:DISPATCH_QUEUE_PRIORITY_DEFAULT];

Serial Queue

[target dispatchOnSerialQueue:^{
  // Busy serial work
}];

[[JSGCDDipatcher sharedDispatcher] submitSerialQueueCompletionListener:^{
 // Serial jobs complete
}];

Background Tasks (iOS)

Invoke this method when you have a task that is important and should not be interrupted if the application is suddenly placed in the background.

[target dispatchBackgroundTask:^(UIBackgroundTaskIdentifier identifier) {
  if(identifier == UIBackgroundTaskInvalid) {
    // Almost out of time to run the task
  } else {
    // Good to go
  }
} priority:DISPATCH_QUEUE_PRIORITY_DEFAULT];

• Better documentation
