objective c - Resize UIImage/UIImageView without keeping aspect ratio -

i have uiimageview i've added pinchgesturerecognizer to. currently, image resized nicely when pinching, want able resize image without maintaining aspect ratio. if user pinches horizontally, image view's width enlarge; if pinch vertically, height enlarge , forth.

can give me hint on how please?

write custom gesture recognizer requires 2 fingers on screen. 1 time both fingers on screen store offset imageview's border in uiedgeinsets.

in touchesmoved, check if both fingers onscreen: if so, calculate new frame applying edgeinsets in current touch position.

header: click implementation: click

works , feels more natural other implementations i've seen.

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...
