iphone - connect UITableView + UITableView -

-

right have indexed uitableview goes detail view want go uitableview detail view.

my code this:

` - (void)tableview:(uitableview *)tableview didselectrowatindexpath:(nsindexpath *)indexpath {

displyanncontroller *ancontroller = [[displyanncontroller alloc] initwithnibname:@"annview" bundle:[nsbundle mainbundle]];  detailviewcontroller *dvcontroller = [[detailviewcontroller alloc] initwithstyle:uitableviewstylegrouped];  switch (indexpath.row) {     case 0:         [self.navigationcontroller pushviewcontroller:ancontroller animated:yes];         [ancontroller release];         ancontroller = nil;         break;     case 1:         [self.navigationcontroller pushviewcontroller:dvcontroller animated:yes];         [dvcontroller release];         dvcontroller = nil;         break;     default:         break; }`

and when press cell index 0 in simulator, program crash!

what's problem? pleas me ..

no, didn't override -initwithnibname, use same way here,but push controlview not tableview.also,no errors in debug console. , have tried release controllers after switch block, program still crash :( anyway, it's work when write:

displyanncontroller *ancontroller = [[displyanncontroller alloc] initwithstyle:uitableviewstylegrouped]];

instead of :

displyanncontroller *ancontroller = [[displyanncontroller alloc] initwithnibname:@"annview" bundle:[nsbundle mainbundle]]

temporarily, accept complete work! hope find example because no need group.

thanks , recommendations.

view debug console (cmd-shift-r) , see error is.

are overriding -initwithnibname message on displyanncontroller? or -viewdidload message?

you have memory leak. +alloc both controllers, -release 1 of them. don't +alloc controller unless going use it.

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...

-
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."
