prepareForSegue not passing correct PFFile - objective-c

Question

When passing a PFFile into new view I am either getting no image or the wrong image.
Here is prepareForSegue method
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([[segue identifier] isEqualToString:#"ShowWine"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
PFObject *object = [self.objects objectAtIndex:indexPath.row];
PFFile *file = [object objectForKey:#"image"];
[[segue destinationViewController] setFile:file];
}
}
And the rest of my relevant implementation file, I just think that I am not getting to the right row in the right section?
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return self.sections.allKeys.count;
}
- (NSString *)wineTypeForSection:(NSInteger)section {
return [self.sectionToWineTypeMap objectForKey:[NSNumber numberWithInt:section]];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSString *wineType = [self wineTypeForSection:section];
NSArray *rowIndecesInSection = [self.sections objectForKey:wineType]; return rowIndecesInSection.count;
}
- (void)objectsDidLoad:(NSError *)error {
[super objectsDidLoad:error];
[self.sections removeAllObjects];
[self.sectionToWineTypeMap removeAllObjects];
NSInteger section = 0;
NSInteger rowIndex = 0;
for (PFObject *object in self.objects) {
NSString *wineType = [object objectForKey:#"wineType"];
NSMutableArray *objectsInSection = [self.sections objectForKey:wineType];
if (!objectsInSection) {
objectsInSection = [NSMutableArray array];
[self.sectionToWineTypeMap setObject:wineType forKey:[NSNumber numberWithInt:section++]];
}
[objectsInSection addObject:[NSNumber numberWithInt:rowIndex++]];
[self.sections setObject:objectsInSection forKey:wineType];
}
}
- (PFObject *)objectAtIndexPath:(NSIndexPath *)indexPath {
NSString *wineType = [self wineTypeForSection:indexPath.section];
NSArray *rowIndecesInSection = [self.sections objectForKey:wineType];
NSNumber *rowIndex = [rowIndecesInSection objectAtIndex:indexPath.row];
return [self.objects objectAtIndex:[rowIndex intValue]];
}

What you should try doing is the following :
Create an instance variable (PFFile *aFile)
In didSelectRowAtIndexPath:, call your objectAtIndexPath: method, and set aFile with the returning value
Still in didSelectRowAtIndexPath:, call your performSegueWithIdentifier: and in prepareForSegue:, just set the destination file to your var : [[segue destinationViewController] setFile: aFile];.
Try this, and see if it works better. If not, please let me know !
