How to save downloaded content/data in the given path in document directory by NSOutputStream. If i append file name with DD then it works (ex- DD/contentPath.zip), But if i append a path like DD/hello/contentPath.zip then it doesn't work. Why ? I tried like below -
- (void) downloadCarContents:(NSString *)url forContent:(NSString *)contentPath {
//NSString *destinationPath = [self.documentDirectory getDownloadContentPath:contentPath];
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestOperation *op = [manager GET:url
parameters:nil
success:^(AFHTTPRequestOperation *operation, id responseObject) {
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
//NSLog(@"Error : %@", error.localizedDescription);
}];
NSString *documentsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *dest = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"hello/%@.zip", contentPath]];// It doesn't work
//NSString *dest = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.zip", contentPath]];// It works
op.outputStream = [NSOutputStream outputStreamToFileAtPath:dest append:NO];
[op setDownloadProgressBlock:^(NSUInteger bytesRead, long long totalBytesRead, long long totalBytesExpectedToRead) {
float percentage = (float) (totalBytesRead * 100) / totalBytesExpectedToRead;
[self.delegate downloadProgression:percentage];
}];
}
The API doesn't create the folder for you. Your code needs to ensure it exists before you try to use it. NSFileManager can help with createDirectoryAtPath:withIntermediateDirectories:attributes:error:
