HI,
Im trying to use file service to upload and download file which are specific to a single user in my table.
I’m using the following file for upload
NSString *imgFileName = [NSString stringWithFormat:@"img/%0.0f.jpeg", [[NSDate date]timeIntervalSince1970]];
NSURL *url = [NSURL URLWithString:fbPic];
NSData *imageData = [[NSData alloc]initWithContentsOfURL:url];
[backendless.fileService upload:imgFileName content:imageData response:^(BackendlessFile *uploadFile) {
[user setProperty:@"imageURL" object:uploadFile];
NSLog(@"File Uploaded successfully %@", uploadFile);
[backendless.userService update:user];
} error:^(Fault *fault1) {
NSLog(@"file upload fault %@", fault1);
}];
File uploads successfully to my user table and is stored as shown:
http://support.backendless.com/public/attachments/0d304900037acf19ea7c88106f1cee68.png</img>
In the next View Controller, I’m trying to download this file using the following code:
BackendlessUser *user = [backendless.userService currentUser];
NSString *objectID = [user getProperty:@"objectId"];
[backendless.userService findById:objectID response:^(BackendlessUser *user) {
NSLog(@"User Details %@", [user getProperty:@"deviceId"]);
self.nameLabel.text = [user getProperty:@"name"];
imageURL = [user getProperty:@"imageURL"];
NSLog(@"image url is %@", imageURL);
NSURL *url = [NSURL URLWithString:imageURL];
NSData *urlData = [NSData dataWithContentsOfURL:url];
self.personalPic.image = [UIImage imageWithData:urlData];
} error:^(Fault *fault) {
NSLog(@"Error retrieving user details: %@", fault);
}];
The log prints out the following:
image url is <BackendlessFile> → fileURL: https://api.backendless.com/8d33a918-3dd1-85bd-ffd0-10b7f2458900/v1/files/img/1459791481.jpeg
But I get a crash on line 12:
-[BackendlessFile length]: unrecognized selector sent to instance 0x7fc60a55c410
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[BackendlessFile length]: unrecognized selector sent to instance 0x7fc60a55c410'
How do I download a file? I know its something to do with the URL call. And the URL string seems to have other information attached to it “<BackendlessFile> → fileURL:”
How do I get just the URL so that I can download the file…
Thanks
