Update a tableView with a plist took from another table
- by Pheel
Background:
I have a tab bar application, which has a tableView as the "heart" of the app. It loads data from a plist and, through a button that checks if there are any updates on the remote plist file, updates the local plist with the remote contents.
Then, i have another tableView, that should display only those plist items that have a bool value set to YES.
Now i want to add a button to the second table that reloads the plist took from the first table.
Expected:
When i update the local plist from the first table and when i press the button on the second table, the 2nd table is supposed to update and show the cells with that bool value set to YES.
(Note: I set YES as default to some items on plist).
What happens:
The first table updates its content from remote. The second table shows the old items with the value set to YES. When i press the button to refresh data, it reads the plist fine (by logging it, it has the same contents of the first table -only those set to YES-),but it doesn't update data even if i have [self.tableView reloadData];. When i close the app and open it again, the second table is filled with the right items. :\
Code i'm using:
//Reading Plist
{
NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *plistPath = [[documentPaths lastObject] stringByAppendingPathComponent:@"myPlist.plist"];
NSFileManager *fMgr = [NSFileManager defaultManager];
if (![fMgr fileExistsAtPath:plistPath]) {
plistPath = [[NSBundle mainBundle] pathForResource:@"myPlist" ofType:@"plist"];
}
NSMutableArray *returnArr = [NSMutableArray arrayWithContentsOfFile:plistPath];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"isFav == YES"];
for (NSDictionary *sect in returnArr) {
NSArray *arr = [sect objectForKey:@"Rows"];
[sect setValue:[arr filteredArrayUsingPredicate:predicate] forKey:@"Rows"];
}
[self.tableView reloadData];
}
//Refresh data button
- (void) refreshTable:(id)sender
{
NSLog(@"plist read");
[self readPlist];
NSLog(@"refreshed plist:%@",[self readPlist]);
[self.tableView reloadData];
}
Does anyone know why the table is not updating?
