objective c - To Get all Images from Photo Library in iphone -


i trying retrive images photo library & display in app using assetslibrary. got url path of photos don't know how photo through it.

my code follow:

 nsmutablearray* asseturldictionaries = [[nsmutablearray alloc] init]; void (^assetenumerator)( alasset *, nsuinteger, bool *) = ^(alasset *result, nsuinteger index, bool *stop) { if(result != nil) { if([[result valueforproperty:alassetpropertytype] isequaltostring:alassettypephoto]) { [asseturldictionaries addobject:[result valueforproperty:alassetpropertyurls]]; nslog(@"result is:%@",result); nslog(@"asset urldictionary is:%@",asseturldictionaries); nsurl *url= (nsurl*) [[result defaultrepresentation]url]; [library assetforurl:url resultblock:^(alasset *asset) { [assetsp addobject:asset]; } failureblock:^(nserror *error){ nslog(@"test:fail"); } ]; } } }; nsmutablearray *assetgroups = [[nsmutablearray alloc] init]; void (^ assetgroupenumerator) ( alassetsgroup *, bool *)= ^(alassetsgroup *group, bool *stop){ nslog(@"hi"); if(group != nil) { [group enumerateassetsusingblock:assetenumerator]; [assetgroups addobject:group]; nslog(@"number of assets in group :%d",[group numberofassets]); } }; assetgroups = [[nsmutablearray alloc] init]; alassetslibrary *library = [[alassetslibrary alloc] init]; [library enumerategroupswithtypes:alassetsgroupall usingblock:assetgroupenumerator failureblock:^(nserror *error) {nslog(@"a problem occurred");}];

this code fetched elcimagepickercontroller example here modifications done simplification.

may you

[self.assetgroup enumerateassetsusingblock:^(alasset *result, nsuinteger index, bool *stop) { if(result == nil) return; uiimageview *assetimageview = [[uiimageview alloc] initwithframe:viewframes]; [assetimageview setcontentmode:uiviewcontentmodescaletofill]; [assetimageview setimage:[uiimage imagewithcgimage:[result thumbnail]]]; }];

happy coding :)

new answer

just use

[uiimage imagewithcgimage:[[asset defaultrepresentation] fullscreenimage]]

to store image directly instead of storing asset @ time of storing asset in assetsp

just follow

void (^assetenumerator)( alasset *, nsuinteger, bool *) = ^(alasset *result, nsuinteger index, bool *stop) { if(result != nil) { if([[result valueforproperty:alassetpropertytype] isequaltostring:alassettypephoto]) { [asseturldictionaries addobject:[result valueforproperty:alassetpropertyurls]]; nslog(@"result is:%@",result); nslog(@"asset urldictionary is:%@",asseturldictionaries); nsurl *url= (nsurl*) [[result defaultrepresentation]url]; [library assetforurl:url resultblock:^(alasset *asset) { //your line //[assetsp addobject:asset]; //my changed line store image directly assetsp [assetsp addobject:[uiimage imagewithcgimage:[[asset defaultrepresentation] fullscreenimage]]]; } failureblock:^(nserror *error){ nslog(@"test:fail"); } ]; } } };

try code store alasset data in mutable array

nsmutablearray *returnarray = [[nsmutablearray alloc] init]; for(alasset *asset in _assets) { nsmutabledictionary *workingdictionary = [[nsmutabledictionary alloc] init]; [workingdictionary setobject:[asset valueforproperty:alassetpropertytype] forkey:@"uiimagepickercontrollermediatype"]; [workingdictionary setobject:[uiimage imagewithcgimage:[[asset defaultrepresentation] fullscreenimage]] forkey:@"uiimagepickercontrolleroriginalimage"]; [workingdictionary setobject:[[asset valueforproperty:alassetpropertyurls] valueforkey:[[[asset valueforproperty:alassetpropertyurls] allkeys] objectatindex:0]] forkey:@"uiimagepickercontrollerreferenceurl"]; [returnarray addobject:workingdictionary];

and image in uiimageview this

nsdictionary *dict = [info objectatindex:i]; uiimageview *imageview = [[uiimageview alloc] initwithimage:[dict objectforkey:uiimagepickercontrolleroriginalimage]]; [imageview setcontentmode:uiviewcontentmodescaleaspectfit];

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
