一、将视频保存本地设备
Git地址：https://github.com/gaoguangxiao/SaveToCamera
- (void)saveAction{
NSMutableArray *video = [NSMutableArray arrayWithCapacity:3];
NSArray *moves = [[NSBundle mainBundle]pathsForResourcesOfType:@"mov" inDirectory:nil];
[video addObjectsFromArray:moves];
for (id item in video) {
if (UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(item)) {
NSLog(@"保存成功");
UISaveVideoAtPathToSavedPhotosAlbum(item, nil, nil, NULL)
}
}
}
二、本地音视频资源的获取
//获取所有资源的集合，按照时间进行排序
PHFetchOptions *options = [[PHFetchOptions alloc] init];
options.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:YES]];
PHFetchResult *assetsFetchResults = [PHAsset fetchAssetsWithOptions:options];
//这时 assetsFetchResults 中包含的，应该就是各个资源（PHAsset）
for (NSInteger i = 0; i < assetsFetchResults.count; i++) {
// 获取一个资源（PHAsset）
PHAsset *phAsset = assetsFetchResults[i];
if (phAsset.mediaType == PHAssetMediaTypeVideo) {
PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
options.version = PHImageRequestOptionsVersionCurrent;
options.deliveryMode = PHVideoRequestOptionsDeliveryModeAutomatic;
PHImageManager *manager = [PHImageManager defaultManager];
[manager requestAVAssetForVideo:phAsset options:options resultHandler:^(AVAsset * _Nullable asset, AVAudioMix * _Nullable audioMix, NSDictionary * _Nullable info) {
AVURLAsset *urlAsset = (AVURLAsset *)asset
NSURL *url = urlAsset.URL;
NSData *data = [NSData dataWithContentsOfURL:url];
NSLog(@"%@",data);
}];
}else if (phAsset.mediaType == PHAssetMediaTypeImage){
PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init];
options.version = PHImageRequestOptionsVersionCurrent;
//返回图片的质量类型 （效率高，质量低）
options.deliveryMode = PHImageRequestOptionsDeliveryModeFastFormat;
//同步请求获取iCloud图片（默认为NO）
//options.synchronous = YES;
[[PHImageManager defaultManager] requestImageDataForAsset:asset options:options resultHandler:^(NSData * _Nullable imageData, NSString * _Nullable dataUTI, UIImageOrientation orientation, NSDictionary * _Nullable info) {
data = [NSData dataWithData:imageData];
if (completion && data.length > 0) {
completion(mediaName, data);
}
}];
}
}
三、图片选择资源库
