To Get all Images from Photo Library in iphone
12,726
Solution 1
This code is fetched from some ELCImagePickerController example from here Some modifications are done for simplification.
May this will help 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 the asset at the time of storing asset in assetsp
just as 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 will store image directly to assetsp
[assetsp addObject:[UIImage imageWithCGImage:[[asset defaultRepresentation] fullScreenImage]]];
}
failureBlock:^(NSError *error){ NSLog(@"test:Fail"); } ];
}
}
};
NEW ANSWER 1
Try this code to store the 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 to get the image in UIImageView just do this
NSDictionary *dict = [info objectAtIndex:i];
UIImageView *imageview = [[UIImageView alloc] initWithImage:[dict objectForKey:UIImagePickerControllerOriginalImage]];
[imageview setContentMode:UIViewContentModeScaleAspectFit];

My code is as follows:
- (void)viewDidLoad
{
carousel.type = iCarouselTypeCoverFlow2;
[super viewDidLoad];
xy =[[NSMutableArray alloc]init];
NSMutableArray* assetURLDictionaries = [[NSMutableArray alloc] init];
ALAssetsLibrary *library = [[ALAssetsLibrary 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) {
[xy addObject:[UIImage imageWithCGImage:[[asset defaultRepresentation] fullScreenImage]]];
NSLog(@" xy is:%@",xy);
image =[ [UIImageView alloc ] initWithImage:[xy objectAtIndex:0]];
NSLog(@"image is:%@",image);
}
failureBlock:^(NSError *error){ NSLog(@"test:Fail"); } ];
}
}
};
NSMutableArray *assetGroups = [[NSMutableArray alloc] init];
void (^ assetGroupEnumerator) ( ALAssetsGroup *, BOOL *)= ^(ALAssetsGroup *group, BOOL *stop) {
NSLog(@"hello");
if(group != nil) {
[group enumerateAssetsUsingBlock:assetEnumerator];
[assetGroups addObject:group];
NSLog(@"Number of assets in group :%d",[group numberOfAssets]);
NSLog(@"asset group is:%@",assetGroups);
}
};
assetGroups = [[NSMutableArray alloc] init];
[library enumerateGroupsWithTypes:ALAssetsGroupAll
usingBlock:assetGroupEnumerator
failureBlock:^(NSError *error) {NSLog(@"A problem occurred");}];

I trying to retrive images from Photo Library & display in my app using AssetsLibrary. I got the URL path of photos but I don't know how to get photo through it.
My Code is as 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");}];
