iphone - Objective-C NSMutableArray mutated while being enumerated? -

i kinda stumbled error seek remove objects nsmutablearray while other objects beingness added elsewhere. maintain simple, have no clue on how prepare it. here i'm doing:

i have 4 timers calling 4 different methods adds object same array. now, when press button, need remove objects in array (or @ to the lowest degree some). tried first invalidate 4 timers, , work want array, , fire timers. thought would've worked since not using timers anymore enumerate through array, seemingly doesn't work.

any suggestions here?

it's nil timers. because (i assume) timers working on same thread modifying method don't need stop , start them. ios doesn't utilize interrupt model timer callbacks, have wait turn other event :)

you're doing like

for (id object in myarray) if (somecondition) [myarray removeobject:object];

you can't edit mutable array while you're going through need create temporary array hold things want remove

// find things remove nsmutablearray *todelete = [nsmutablearray array]; (id object in myarray) if (somecondition) [todelete addobject:object]; // remove them [myarray removeobjectsinarray:todelete];

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...
