iphone - Why doesen't it work to write this NSMutableArray to a plist? -

-

edited.

hey, trying write nsmutablearray plist. compiler not show errors, not write plist anyway. have tried on real device too, not simulator.

basically, code does, when click accessoryview of uitableviewcell, gets indexpath pressed, edits nsmutablearray , tries write nsmutablearray plist. reloads arrays mentioned (from multiple plists) , reloads data in uitableview arrays.

code:

nsindexpath *indexpath = [table indexpathforrowatpoint:[[[event touchesforview:sender] anyobject] locationinview:table]];  [arrayfav removeobjectatindex:[arrayfav indexofobject:[nsnumber numberwithint:[[arraysub objectatindex:indexpath.row] intvalue]]]];  nsstring *rootpath = [nssearchpathfordirectoriesindomains(nsdocumentdirectory, nsuserdomainmask, yes) objectatindex:0]; nsstring *plistpath = [rootpath stringbyappendingpathcomponent:@"arrayfav.plist"]; nslog(@"%@ - %@", rootpath, plistpath);    [arrayfav writetofile:plistpath atomically:yes];      // reloads data arrays [self loaddatafromplists];  // reloads data in tableview arrays [tablefarts reloaddata];

cfshow() on array after removing 1 of them shows this:

<cfarray 0x6262110 [0x2c810a0]>{type = mutable-small, count = 4, values = (     0 : <cfnumber 0x6502e10 [0x2c810a0]>{value = +3, type = kcfnumbersint32type}     1 : <cfnumber 0x6239de0 [0x2c810a0]>{value = +8, type = kcfnumbersint32type}     2 : <cfnumber 0x6239dc0 [0x2c810a0]>{value = +10, type = kcfnumbersint32type}     3 : <cfnumber 0x6261420 [0x2c810a0]>{value = +40, type = kcfnumbersint64type}

debug-info: writetoplist shows yes, have tried release arrays before filling them again, setting them nil, set atomically no.

as discussed in comments below, actual problem here plist being read , written 2 different locations. somewhere in app, there code reads file array similar this:

nsstring *plistfavpath = [[nsbundle mainbundle] pathforresource:@"arrayfav"                                                           oftype:@"plist"];  arrayfav = [[nsmutablearray alloc] initwithcontentsoffile:plistfavpath];

this logic reads array application's bundle, read-only location , part of distributed app. later when edited array persisted, code similar used:

nsstring *rootpath = [nssearchpathfordirectoriesindomains(nsdocumentdirectory,                                                           nsuserdomainmask,                                                           yes) objectatindex:0]; nsstring *plistpath = [rootpath                            stringbyappendingpathcomponent:@"arrayfav.plist"]; nslog(@"%@ - %@", rootpath, plistpath);  [arrayfav writetofile:plistpath atomically:yes];

the result here updated file gets written app's documents directory, never read there, giving appearance file not being saved correctly. correct this, should change code reads file use same path writing to.

if need distribute default version of plist use on initial launch before array has been edited, continue include version of file in bundle , add code app delegate check if file exists in documents directory , if not present, copies bundle's default version of file proper place.

javascript - Enclosure Memory Copies -

function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
