ios - How to react to UIControl resize when its data changes -

i've built uicontrol subclass display 1-month calendar view on iphone. months require 5 weeks display dates, months need 6, i've built command dynamically resize needed. i'm using uiview animation alter frame of command here. the problem is, need other controls on screen move/resize when calendar changes size. , need happen animation of calendar command changing size. ideally, i'd without coding bunch of details in calendar command other controls on screen. what's best strategy here? hoping somehow anchor other controls frame of calendar command , have platform adjust location/size animates frame change. but, far, can't find combination of struts , springs create happen. do need bite bullet , add together other on-screen controls animation happening within calendar control?

i'll interested see if there improve answers this.

at point, know override setframe on calendar view , when changes, send setneedslayout superview.

but i'm not sure if standard views autoresize correctly. geometry flows downwards view tree, not up, , want both.

you may have implement layoutsubviews on containing view.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
