i have question regarding data updates in react lifecycle. the newstable child component receives props (query) parent component, calls database , renders table. parent send updated props (new queries) table can updated. if parent fires same query twice, table shouldn't update (that is, shouldn't keep hitting database identical queries). now, use shouldcomponentupdate handle this, use "debounce" library. here's code snippet: import react 'react'; var newstable = react.createclass({displayname: "newstable", getdefaultprops: function() { return { }; }, getinitialstate: function() { return { query: null }; }, componentwillmount: function() { this.loaddata(this.props.query); }, componentdidmount: function() { }, componentwillunmount: function() { }, loaddata: function(query) { // time-consuming async, return "data" ...

i'm new ios development , stupid question experienced guys... when create new ios project in xcode, viewcontroller class , storyboard sets custom class viewcontroller . looks there "storyboard" class holding instance of viewcontroller , however, cannot find "storyboard" class defined. even though know how create multiple subclasses of uiviewcontroller handle different views interaction following tutorials, still find uncomfortable associate these subclasses storyboard selecting them in storyboard panel. rather see "storyboard" class holding array of uiviewcontroller . so question is, how these uiviewcontroller interact storyboard under hood? thanks roughly, happens follows: app launches. app loads storryboard. depending on app's navigation structure, app instantiates each view controller inside storyboard needed. the storyboard contains detailed information on: which custom subclass of uiviewcontroller , uinavigt...
