How to save multiple videos into application document directory? - ios

Question

I am using GMImagePicker to fetch assets of camera roll.
After selecting single or multiple videos i got PHAsset in arrayArray.
assetArray data in this formate
"<PHAsset: 0x7fe0e8f21130> 40D4733D-4C7B-443D-8093-C28E39ACA45E/L0/001 mediaType=2/0, sourceType=1, (720x480), creationDate=2016-02-14 09:50:58 +0000, location=0, hidden=0, favorite=0 "
How can i store this video into my application document directory?
The code i did to store video is
for (PHAsset *asset in assetArray) {
if (asset.mediaType==PHAssetMediaTypeVideo) {
NSLog(#"Video found");
}
PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
options.version = PHVideoRequestOptionsVersionOriginal;
[[PHImageManager defaultManager] requestAVAssetForVideo:asset options:options resultHandler:^(AVAsset *asset, AVAudioMix *audioMix, NSDictionary *info) {
if ([asset isKindOfClass:[AVURLAsset class]]) {
NSURL *URL = [(AVURLAsset *)asset URL];
NSMutableData *responseData=[[NSMutableData alloc] init];
responseData = [NSMutableData dataWithContentsOfURL:URL];
if (responseData.length>0) {
NSString * lastPath = [URL.absoluteString lastPathComponent];//videoname.mp4
NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES)objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#",docDirPath,lastPath];
[responseData writeToFile:filePath atomically:YES];
}
}];
}
I also checked filepath where video is saved. Video is available but i get this error.
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'
Please help me to solve this.

According to me use NSMutableData instead of NSData it's accept Nullable value
self.responseData = [NSMutableData dataWithContentsOfURL:location];
if (self.responseData.length>0) {
dispatch_async(dispatch_get_main_queue(), ^{
NSString * lastPath = [url.absoluteString lastPathComponent];//videoname.mp4
NSString *docDirPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES)objectAtIndex:0];
NSString *filePath = [NSString stringWithFormat:#"%#/%#",docDirPath,lastPath];
[self.responseData writeToFile:filePath atomically:YES];
}
});
hope this help you.

For storing both Images And Video
for (PHAsset *asset in assetArray) {
if (asset.mediaType==PHAssetMediaTypeVideo) {
NSLog(#"Video found");
PHVideoRequestOptions *options = [[PHVideoRequestOptions alloc] init];
options.version = PHVideoRequestOptionsVersionOriginal;
[[PHImageManager defaultManager] requestAVAssetForVideo:asset options:options resultHandler:^(AVAsset *asset, AVAudioMix *audioMix, NSDictionary *info) {
if ([asset isKindOfClass:[AVURLAsset class]]) {
NSURL *URL = [(AVURLAsset *)asset URL];
[Albumvideos addObject:URL];
NSData *videoData = [NSData dataWithContentsOfURL:URL];
if (videoData.length>0) {
NSString *lastPath = [URL.absoluteString lastPathComponent];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#-%#",TimeStamp,lastPath]];
[fileManager createFileAtPath:fullPath contents:videoData attributes:nil];
}
}
}];
}
else{
self.requestOptions = [[PHImageRequestOptions alloc] init];
self.requestOptions.resizeMode = PHImageRequestOptionsResizeModeExact;
self.requestOptions.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
// this one is key
self.requestOptions.synchronous = true;
// self.assets = [NSMutableArray arrayWithArray:assets];
PHImageManager *manager = [PHImageManager defaultManager];
// assets contains PHAsset objects.
__block UIImage *ima;
// Do something with the asset
[manager requestImageForAsset:asset
targetSize:PHImageManagerMaximumSize
contentMode:PHImageContentModeDefault
options:self.requestOptions
resultHandler:^void(UIImage *image, NSDictionary *info) {
ima = image;
[Albumimages addObject:ima];
}];
}
}
Albumvideos is mutable array which contain video URL and Albumimages contain selected images.
