UIActivityViewController's twitter item - change post action on "post"

Question

is there a way to perform/override a different action on twitter's post popup when pressing "post" button ?

My code:

NSData *imgData = [NSData dataWithContentsOfFile:[NSString stringWithUTF8String:imgPath]];
NSArray *activityItems = @["Here is a gif image",imgData];
UIActivityViewController *activityController =[[UIActivityViewController alloc]initWithActivityItems:activityItems
 applicationActivities:nil];
