at moment, iphone app uses nsmutablearrays hold onto nsstrings. have more information want associate each entry in each array. example, had 1 thing put in array1[0], string. now, however, along string want associate string , integer. guess like: old: [string] new [string, string, integer] i thinking of using dictionary i'm not sure if it's right. advice? the elements in nsarray dictionaries, c structs , or objective-c objects. a dictionary works, can cumbersome if you’re storing primitive data type values (need boxed, e.g. nsnumber ) or there’s potential extending data in deeper levels (dictionary containing dictionary containing dictionary). also, dictionary objects not implicitly typed. a c struct works needs boxing, , don’t benefit cocoa collection semantics regard memory management — have on own. also, there’s no implicit support copy/retain semantics struct members. i declare objective-c class aggregate data types stored in collections such nsa...

i have spent hours reading how upload large files server. these video files in hundreds of megabytes, , in .mp4 format. my first attempt using php processing post, not working files above 2 megabytes due restrictions in php.ini , httpd.conf. some users increasing these limits levels needed, , hoping upload work. some websites seem using flash uploaders, ones have tried have been difficult, , never explicitly mentioned if solved upload size problem. i have looked @ ftp using php client, examples found transferring file ftp server after had been posted. ftp using separate client out of question, file name , related data stored in database. currently, operating on localhost, , site served box have physical access to, still wary of increasing max_upload_size , related requirements because want move hosted service. what best solution? there way upload large files strictly through php , html? if not, best solution upload large files while still being able pass filename databa...

the more developer android apps, more discover inconsistencies between emulators , real devices, have others, i'm sure. (the latest frustration comes after spending hours chasing app widget ghosts. ghosts appear on emulator, don't otherwise appear on of real devices have access to.) has come across repositories (e.g., wikis, blogs, forums) of known emulator shortcomings? i'd rather spend little time reading known problems, many hours more chasing them in circles. -- part of answer: one can query the android issues database "emulator", not matches emulator problems - have word "emulator" in title or description.

a bit new programming , had general question thought of. say, have database bunch of stock information , 1 column price , earnings. price/earning ratio, better calculate everyday or calculate on demand? think performance wise, it'd quicker read i'm wondering if math type functions worth batch job pre-calculate it(is noticeable?). so how professionals it? have application process data them or have available in database? the professionals use variety of methods. depends on you're going for. new real ratios need displayed immediately ? how core data changing? ideally calculate ratio time price or earning changes, takes development, , it's not worth if don't have substantial amount of activity on site. on other hand, if you're receiving hundreds of visits every minute, you're going want cache whatever you're calculating, time required re-display cached result less recreating result (in scenarios). however, general rule of thumb, don...

alright, have problem on hands. i'm trying convert project universal app iphone , ipad. i'm trying make ipad-specific versions of xib files. it's not possible create ipad version using autoresizing masks in xcode 4, assumed i'd able pop xib xcode 3's version of ib, , let magic. no dice. here's error when try open xib file in ib: to honest don't know proceed here. guess resize views manually, that's quite tedious , don't have time doing that. ideas? alright, figured out rather convoluted workaround. first of all, duplicate original project , select project info. right-click on target, , select "duplicate". xcode pop message. select "duplicate , transition ipad". now xcode converts xib files you, , presents ipad resources folder. now open these xib files in finder, , append ~ipad after file name. after doing so, copy these xib files original project, , turn project universal project se...

how define null string, date or integer in vba? i need able assign null value fields records when data incomplete or irrelevant, if declare variable string, date or integer, errors when trying assign null value. is solution use variant? if so, point of other datatypes in vba? dim x variant x = null only variant data type can hold value null . a variant special data type can contain kind of data [...] variant can contain special values empty, error, nothing, , null . the "point" of other data types precisely cannot contain ol' kind of data. has 2 advantages can think of: it's more difficult programmer assign data of unintended type variable mistake, since detected @ compile time. can prevent bugs , make things clearer , next person maintaining code. narrow data types save storage space. putting integers in variant (16 bytes) takes way more memory putting them in int (2 bytes). becomes significant if have large arrays. of course, varia...

i have created settings bundle single preference value, text field default value. when application launches , retrieve value null. have manually code value use before user has provided value? also if user preferences screen , enters text field leave without making changes value not set ... user has change value saved, correct? no, don't that. there's function this: id userdefaults = [nsuserdefaults standarduserdefaults]; [userdefaults registerdefaults: defaultsettings]; you can build parameter iterating sub keys of preferencespecifiers in settings plist file. something this: - (nsdictionary *)readdefaultsettingsfromplist: (nsstring *)inpath; { id mutable = [nsmutabledictionary dictionary]; id settings = [nsdictionary dictionarywithcontentsoffile: inpath]; id specifiers = [settings objectforkey: @"preferencespecifiers"]; (id prefitem in specifiers) { id key = [prefitem objectforkey: @"key"]; id valu...

what i'm doing: i reading data off file several times while app runs. use following code so: nsstring *datapath = [[[nsbundle mainbundle] resourcepath] stringbyappendingpathcomponent:@"data.txt"]; nsstring *data = [nsstring stringwithcontentsoffile:datapath encoding:nsstringencodingconversionexternalrepresentation error:null]; nsarray *components = [data componentsseparatedbystring:@"|||||"]; the first time called, works expected - array of length 5, each section containing relevant string. what goes wrong: this file never modified. yet, when call same procedure second time (or third, fourth etc) don't same result. instead, array of length 1 returned, containing part of necessary data. why? can't see reason go wrong... appreciated! since file in appbundle means can't modify file @ all. sure that, ever code called, autorelease object retained correctly? if call block of code every time want data, might idea save results of f...

i want send direct message more 1 person single call i using mgtwitterengine and calling function this [requestdict setobject:@"direct_message" forkey:[twitterobj senddirectmessage:@"this test iphone app" to:@"user_id"]]; this sending ok but not able send multiple people , how can tried comma separated user_ids not works thanks amit battan regardless of whether mgtwitterengine supports call looks allows send direct message (dm) more 1 user, twitter api doesn't support call that. the api method behind scenes ( direct_messages/new ) allows authenticating user send dm 1 user only. so, if single call working you, iterate on list of twitter users , send them dm call specified. also, don't have worry rate limiting when sending dm.
