Saving memory #26
Description
Problem:
I sync 15 MB files using FTASync and the instruments says that [FTASyncHandler syncAll] takes 15MB memory which is not reasonable
So I changed the code in FTASyncParent.m :
- (void)updateObjectWithRemoteObject:(PFObject *)parseObject {
NSDictionary *attributes = [[self entity] attributesByName];
NSDictionary *relationships = [[self entity] relationshipsByName];
//Set all the attributes
if (self.syncStatusValue != 1) { //Local changes take priority
for (NSString *attribute in attributes) {
NSString *className = [[attributes valueForKey:attribute] attributeValueClassName];
if ([className isEqualToString:@"NSData"]) {
PFFile* remoteFile = [parseObject objectForKey:attribute];
[self setValue:[remoteFile getData] forKey:attribute]; //CHANGED HERE
remoteFile = nil; //CHANGED HERE
continue;
}
And I run the app again and the [FTASyncHandler syncAll] takes 33.88KB only this time (see the attachment photo:)
(Note: in .xcdatamodel, the binary data field, I checked the "Allows External Storage" box to reduce use of memory of core data)
Can you please update the code in FTASync according to the code above?
