32,221 PointsFile upload size
I am trying to upload a image/video to my backend and I would like check the file size before uploading it. This is what I have done so far.
-(BOOL)returnFileSize:(NSString *)URL{
NSError *attributesError;
BOOL _isWithInFileSizeLimit = NO;
NSDictionary *fileAttributes = [[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&attributesError];
NSNumber *fileSizeNumber = [fileAttributes objectForKey:NSFileSize];
TFLog(@"Uploading file size of limit .. %d", (int)fileSizeNumber);
NSLog(@"UPLOAD FILE SIZE... %d", (int)fileSizeNumber);
if ((long)[fileSizeNumber longValue] <= 15) {
_isWithInFileSizeLimit = YES;
}
return _isWithInFileSizeLimit;
}
// calling the above method, which doesn't work. It always returns file size as 0.
NSString *URL = [((NSURL *)[info objectForKey:UIImagePickerControllerReferenceURL]) absoluteString];
if ([self returnFileSize: URL]) {
[self uploadMedia];
}else{
// Display Errir Message;
}
Any suggestions?

42,016 Pointsthe fileSize is an unsigned long. try replacing
NSNumber *fileSizeNumber = [fileAttributes objectForKey:NSFileSize];
with
NSNumber *fileSizeNumber = [NSNumber numberWithUnsignedLong:[fileAttributes objectForKey:NSFileSize]];

32,221 Points2 things, it's warning me with the below message.
- incompatible pointer to integer conversion sending 'id' to parameter of type 'unsigned long'
- still getting 0 as value.

42,016 Pointswhats the line of code thats giving you that error?
harishupadhyayula
32,221 PointsAnd I checked "fileAttributes" dictionary values and it's 'nil'.

32,221 PointsThe line of code you suggested.

42,016 Pointshmm alright. Just found this on stack overflow. It will get you the file size all in one line.
uint64_t fileSize = [[[NSFileManager defaultManager] attributesOfItemAtPath:URL error:&attributesError] fileSize];

32,221 PointsNo, it's returning "nil"

42,016 Pointsok so your path doesnt exist. How are you getting the URL?
