How to save video in document directory to gallery in iOS,here i downloaded video from server and saved in document directory and now i want to move it to gallery.
回答1:
UISaveVideoAtPathToSavedPhotosAlbum(sourcePath,nil,nil,nil);
you can pass the sourcePath as
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
append your path or file name to get sourcePath.
NSString *sourcePath = [documentsDirectory stringByAppendingPathComponent:@"youVideo.mp4"];
回答2:
First you need to get particular video Path or Document directory like:-
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"youVideo.mp4"];
NSURL *movieURL = [NSURL fileURLWithPath:path];
ALAssetsLibrary* library = [[[ALAssetsLibrary alloc] init] autorelease];
[library writeVideoAtPathToSavedPhotosAlbum:movieURL
completionBlock:^(NSURL *assetURL, NSError *error){/*notify of completion*/}];
