Question

Say I have an app with the following method strucutre :

[self method1];
[self method2];

And that method 1 contains a dispatch queue such as :

[exportSession exportAsynchronouslyWithCompletionHandler:^{
    switch (exportSession.status) {
        case AVAssetExportSessionStatusFailed:{
            NSLog (@"FAIL");
            break;
        }
        case AVAssetExportSessionStatusCompleted: {
            NSLog (@"SUCCESS");
}
};
 }];

I want to only proceed to execute [method2] once the dispatch queue in method1 has completed. What is the best way to achieve this ?

Answer 1

Put the call to -method2 inside the completion handler block.
