ios - UIPageViewController with Images in iPad3 caches all viewcontrollers in memory -


in arc, have customised uipageviewcontroller mypageviewcontroller. adding mypageviewcontroller childviewcontroller rootviewcontroller. transition type set curl.

imageviewcontrollers added viewcontrollers of mypageviewcontroller this:

imageviewcontroller *startingviewcontroller1 = [self.storyboard instantiateviewcontrollerwithidentifier:@"imageviewcontroller"]; imageviewcontroller *startingviewcontroller2 = [self.storyboard instantiateviewcontrollerwithidentifier:@"imageviewcontroller"];  nsarray *viewcontrollers = @[startingviewcontroller1, startingviewcontroller2]; [self.mypageviewcontroller setviewcontrollers:viewcontrollers direction:uipageviewcontrollernavigationdirectionforward animated:no completion:null];  self.mypageviewcontroller.delegate = self; self.mypageviewcontroller.datasource = self.pagemodelcontroller; [self addchildviewcontroller: self.mypageviewcontroller]; [self.view addsubview: self.mypageviewcontroller.view]; [self.mypageviewcontroller didmovetoparentviewcontroller:self];

each imageviewcontroller has 4 different uiimageviews on it. these images can hd images, in order avoid caching, setting image using:

[uiimage imagewithcontentsoffile:]

but each time turn page in pageviewcontroller, can see 15 mb increased memory , not going down, unless pop whole rootviewcontroller.

but happens in ipad3, whereas memory not increasing in ipad2. both has ios 7.1 installed.

to mypageviewcontroller, 2 viewcontrollers(imageviewcontroller) being added @ time using,

- (uiviewcontroller *)pageviewcontroller:(pmpageviewcontroller *)pageviewcontroller viewcontrollerbeforeviewcontroller:(uiviewcontroller *)viewcontroller; - (uiviewcontroller *)pageviewcontroller:(pmpageviewcontroller *)pageviewcontroller viewcontrollerafterviewcontroller:(uiviewcontroller *)viewcontroller;

in viewdidunload of imageviewcontroller, setting every views & objects nil;

so guess that, ipad3 not releasing view controllers once added it, whereas ipad2 releases previous viewcontrollers , keeps current ones.

is same or there other workarounds this...

can me on please.. have been spending more week on issue now.. kind of suggestions more helpful..

sorry guys, mistake again. there photoframe image setting behind main image. imageview gets direct uiimage data. should have referred image path instead.

i didn't notice earlier. when changed uiimage imagewithcontentsoffile:, worked charm...

commonjs - How to write a typescript definition file for a node module that exports a function? -

consider, toml node module can use: // toml.d.ts declare module toml { export function parse(value:string):any; } declare module "toml" { export = toml; } then: /// <reference path="../../../../../defs/toml/toml.d.ts"/> import toml = require('toml'); toml.parse(...); however, node module export single function, such 'glob' ( https://github.com/isaacs/node-glob ). the node usage of module be: var glob = require("glob") glob("*.js", {}, callback(err, files) { ... }); you'd naively expect this: // glob.d.ts declare function globs(paths:string, options:any, callback:{(err:any, files:string[]):void; ...but because typescripts 'import' semantics bit strange, seems can use 'import .. = require()' statement alias modules . trying call: /// <reference path="../../../../../defs/glob/glob.d.ts"/> import blog = require('glob'); results in: error ts2072: mod

thorough guide for profiling racket code -

did googling ("racket profiling", "racket measure performance"), didn't find , there no examples in docs. did google "profile" search on htdp - no luck. (profile (f ...)) output isn't obvious other small snippets. ideally want python's python -m cprofile usage examples. when search "python profiling", both duckduckgo , google give top result: 26.4. python profilers . (although scanned quickly, seems more of reference "thorough usage guide" examples. if had else in mind, perhaps please link that?) the equivalent racket documentation be: profile: statistical profiler . a usage example: #lang racket (require profile) (profile-thunk (thunk (function-to-profile arg0 arg1) )) here (thunk e) convenience (lambda () e) . bigger example: #lang racket (module mod racket (provide f) (define (f) (for/list ([i 10000]) i))) (require (prefix-in mod: 'mod)) (define (f) (for ([i 10000
