sharing text,data other social app twitter/facebook. can try code below :

nsstring *sharestring = @"text..."; uiimage *shareimage = [uiimage imagenamed:@"image.png"]; nsurl *shareurl = [nsurl urlwithstring:@"http://www.test.com"];  nsarray *activityitems = [nsarray arraywithobjects:sharestring, shareimage, shareurl, nil];  uiactivityviewcontroller *activityviewcontroller = [[uiactivityviewcontroller alloc] initwithactivityitems:activityitems applicationactivities:nil]; activityviewcontroller.modaltransitionstyle = uimodaltransitionstylecoververtical;  [self presentviewcontroller:activityviewcontroller animated:yes completion:nil]; 

it display activity view showing other text sharing app.

or can create custom uiactivity also. in custom uiactivity subclass have override 1 method:

+ (uiactivitycategory)activitycategory {    return uiactivitycategoryshare; }
