I\'ve been trying to create a sharing experience for our app where Instagram launches giving these two options:
Facebook has a pretty lean documentation about i
- (void)postMedia:(NSString *)media Type:(BOOL)isVideo {
[SVProgressHUD showWithStatus:LS(@"Downloading...")];
//download the file in a seperate thread.
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^{
NSURL *url = [NSURL URLWithString:media];
NSData *urlData = [NSData dataWithContentsOfURL:url];
if ( urlData ) {
NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:isVideo?@"instagramShare.mp4":@"instagramShare.jpg"];
NSURL *outputFileURL = [NSURL URLWithString:filePath];
dispatch_async(dispatch_get_main_queue(), ^{
if (![urlData writeToFile:filePath atomically:YES]) {
[SVProgressHUD showErrorWithStatus:LS(@"Failed. Please try again.")];
return;
}
// Check authorization status.
[PHPhotoLibrary requestAuthorization:^( PHAuthorizationStatus status ) {
if ( status == PHAuthorizationStatusAuthorized ) {
// Save the movie file to the photo library and cleanup.
[[PHPhotoLibrary sharedPhotoLibrary] performChanges:^{
// In iOS 9 and later, it's possible to move the file into the photo library without duplicating the file data.
// This avoids using double the disk space during save, which can make a difference on devices with limited free disk space.
PHAssetResourceCreationOptions *options = [[PHAssetResourceCreationOptions alloc] init];
options.shouldMoveFile = YES;
PHAssetCreationRequest *changeRequest = [PHAssetCreationRequest creationRequestForAsset];
if (isVideo)
[changeRequest addResourceWithType:PHAssetResourceTypeVideo fileURL:outputFileURL options:options];
else
[changeRequest addResourceWithType:PHAssetResourceTypePhoto fileURL:outputFileURL options:options];
} completionHandler:^( BOOL success, NSError *error ) {
if ( success ) {
[SVProgressHUD dismiss];
PHFetchOptions *fetchOptions = [[PHFetchOptions alloc] init];
fetchOptions.sortDescriptors = @[[NSSortDescriptor sortDescriptorWithKey:@"creationDate" ascending:NO]];
PHFetchResult *fetchResult;
if (isVideo)
fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeVideo options:fetchOptions];
else
fetchResult = [PHAsset fetchAssetsWithMediaType:PHAssetMediaTypeImage options:fetchOptions];
PHObject *lastAsset = fetchResult.firstObject;
if (lastAsset != nil) {
NSString *localIdentifier = lastAsset.localIdentifier;
NSString *u = [NSString stringWithFormat:@"instagram://library?LocalIdentifier=%@", localIdentifier];
NSURL *url = [NSURL URLWithString:u];
dispatch_async(dispatch_get_main_queue(), ^{
if ([[UIApplication sharedApplication] canOpenURL:url]) {
[[UIApplication sharedApplication] openURL:url options:@{} completionHandler:nil];
} else {
NSString *urlStr = @"https://itunes.apple.com/in/app/instagram/id389801252?mt=8";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:urlStr] options:@{} completionHandler:nil];
}
});
}
}
else {
[SVProgressHUD showErrorWithStatus:LS(@"Failed. Please try again.")];
}
}];
}
}];
});
}
else {
[SVProgressHUD showErrorWithStatus:LS(@"Failed. Please try again.")];
}
});
}
