renderingProcessWithBundleID:interruptionHandler:completion:

Declaration

+ (void) renderingProcessWithBundleID:(NSString *) bundleID interruptionHandler:(void (^)()) interruptionHandler completion:(void (^)(BERenderingProcess *process, NSError *error)) completion;

Parameters

• bundleID:

  The bundle identifier of the rendering extension to launch, or nil to use the default bundle identifier for this app’s rendering extension.

• interruptionHandler:

  A block the system calls if the rendering extension process exits abnormally.

• completion:

  A block the system calls when the process finishes launching.

Discussion

Your browser app can run one instance of each of its rendering extensions. The first time you call this method, the system launches your rendering extension. If you subsequently call this method with the same bundle identifier, or you call renderingProcessWithInterruptionHandler:completion: after previously calling this method with nil as the bundle identifier, your completion handler gets a reference to the same process.

The system guarantees that the process launched when it calls your completion handler.
