ios - Can't set frame of a UIView while it's a child of UIScrollView -


i have created 1 uiview inside uiscrollview storyboard.

enter image description here

i want set frame uiview programatically. have tried set frame using setframe function programatically, its not working uiview inside uiscrollview.

if create 1 uiview inside uiscrollview using [[uiview alloc] initwithframe:cgrectmake(0, 0, 320, 110)],and change size of view,it work!

enter image description here

my code: enter image description here

but want create uiview ib , set frame using setframe function.

most impornatant condition autolayout "true".

most impornatant condition autolayout "true".

if want mix constraints setting view's frame directly, need make sure set view.translatesautoresizingmaskintoconstraints = yes view. afaik, cannot done in ib ios, in code.

also beware setting translatesautoresizingmaskintoconstraints = yes add new constraints define in ib (or programmatically) , have ensure remain consistent, otherwise exception. so, e.g., if set frame origin in code, pinned top distance between view , superview, run problems if specifications not compatible.

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
