You could do:
NSOperation *op = [NSBlockOperation blockOperationWithBlock: ^{
...
}];
[NSOperationQueue mainQueue] addOperations: [NSArray arrayWithObject:
op] waitUntilFinished: YES]
or:
dispatch_sync(dispatch_get_main_queue(), ^{
...
});
but be very careful that you aren't already running on the main
thread, as you could deadlock.
