iphone - Crash when invoking popToRootViewControllerAnimated:NO, set animate to YES work no crash, strange. -

my app based on uinavigationviewcontroller, there 3 viewcontroller in stack, named a, b, c, root view controller, in viewcontroller c next operation, app crash 100%.

- (void) delaypopaction { [[self navigationcontroller] poptorootviewcontrolleranimated:no]; } - (void)searchtap:(id)sender{ [self performselector:@selector(delaypopaction) withobject:nil afterdelay:3.0]; }

trace zombie , find crash dues c has been destroyed there still event available sent him. more strange, if alter animated parameter no yes, no crash happen, maybe dues c's life circle has been enlarged.

see api doc. how no mean? don't understand clearly. animated set value yes animate transition. pass no if setting navigation controller before view displayed.

any thought or suggestion appreciated, in advance.

oh, view-controller implementation defect.

iphone uinavigationcontroller crash

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...
