出门在外也不愁iOS开发之获取系统相册中的图片与视频(内带url转换)
@话不多说,直接上代码
// 必须导入
// 照片原图路径
#define KOriginalPhotoImagePath
[[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@OriginalPhotoImages]
// 视频URL路径
#define KVideoUrlPath
[[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@VideoURL]
// caches路径
#define KCachesPath
[NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) objectAtIndex:0]
// MainViewController
@interface MTHMainViewController ()
@property (nonatomic,strong) MTHNextViewController *nextVC;
@property (nonatomic,strong) NSMutableArray
@property (nonatomic,strong) UIImageView
@implementation MTHMainViewController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
- (void)viewDidLoad
[super viewDidLoad];
// Do any additional setup after loading the view.
self.navigationItem.title = @D
self.view.backgroundColor = [UIColor clearColor];
self.groupArrays = [NSMutableArray array];
// 测试BarItem
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithTitle:@测试 style:UIBarButtonItemStylePlain target:self action:@selector(testRun)];
// 测试手势
UIPanGestureRecognizer *panRecognizer = [[UIPanGestureRecognizer alloc] initWithTarget:self action:@selector(didClickPanGestureRecognizer:)];
[self.navigationController.view addGestureRecognizer:panRecognizer];
// 图片或者视频的缩略图显示
self.litimgView = [[UIImageView alloc] initWithFrame:CGRectMake(100, 200, 120, 120)];
[self.view addSubview:_litimgView];
- (void)testRun
__weak MTHMainViewController *weakSelf =
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
ALAssetsLibraryGroupsEnumerationResultsBlock listGroupBlock = ^(ALAssetsGroup *group, BOOL *stop) {
if (group != nil) {
[weakSelf.groupArrays addObject:group];
[weakSelf.groupArrays enumerateObjectsUsingBlock:^(id obj, NSUInteger idx, BOOL *stop) {

if ([result thumbnail] != nil) {
if ([[result valueForProperty:ALAssetPropertyType] isEqualToString:ALAssetTypePhoto]){

// 和图片方法类似

按照上面方法直接取出来的路径是无法传输的,必须自己转化成NSData对象重新写入沙盒路径
// 将原始图片的URL转化为NSData数据,写入沙盒
- (void)imageWithUrl:(NSURL *)url withFileName:(NSString *)fileName
// 进这个方法的时候也应该加判断,如果已经转化了的就不要调用这个方法了
// 如何判断已经转化了,通过是否存在文件路径
ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
// 创建存放原始图的文件夹---&OriginalPhotoImages
NSFileManager * fileManager = [NSFileManager defaultManager];
if (![fileManager fileExistsAtPath:KOriginalPhotoImagePath]) {
[fileManager createDirectoryAtPath:KOriginalPhotoImagePath withIntermediateDirectories:YES attributes:nil error:nil];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
if (url) {
// 主要方法
[assetLibrary assetForURL:url resultBlock:^(ALAsset *asset) {
ALAssetRepresentation *rep = [asset defaultRepresentation];
Byte *buffer = (Byte*)malloc((unsigned long)rep.size);
NSUInteger buffered = [rep getBytes:buffer fromOffset:0.0 length:((unsigned long)rep.size) error:nil];
NSData *data = [NSData dataWithBytesNoCopy:buffer length:buffered freeWhenDone:YES];
NSString * imagePath = [KOriginalPhotoImagePath stringByAppendingPathComponent:fileName];
[data writeToFile:imagePath atomically:YES];
} failureBlock:nil];
// 将原始视频的URL转化为NSData数据,写入沙盒
- (void)videoWithUrl:(NSURL *)url withFileName:(NSString *)fileName
// 解析一下,为什么视频不像图片一样一次性开辟本身大小的内存写入?
// 想想,如果1个视频有1G多,难道直接开辟1G多的空间大小来写?
ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
if (url) {
[assetLibrary assetForURL:url resultBlock:^(ALAsset *asset) {
ALAssetRepresentation *rep = [asset defaultRepresentation];
NSString * videoPath = [KCachesPath stringByAppendingPathComponent:fileName];
char const *cvideoPath = [videoPath UTF8String];
FILE *file = fopen(cvideoPath, a+);

// 初始化一个1M的buffer
Byte *buffer = (Byte*)malloc(bufferSize);
NSUInteger read = 0, offset = 0, written = 0;
NSError* err =
if (rep.size != 0)
read = [rep getBytes:buffer fromOffset:offset length:bufferSize error:&err];
written = fwrite(buffer, sizeof(char), read, file);
