UItableView plist数据排序

Question

Hi I have created a table view which filled with a plist data , I need re ordering the cells , I mean instead of showing data like this :

1
2
3
4
5

should be like this :

5
4
3
2
1

I am using this code :

NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"self" ascending:NO];
    titles =  [[titles sortedArrayUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]] retain]; 

in this method :

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

but the result is something like this

1
5
2
4
3 

how can I fix it ?

EIDTED :

my plist :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<array>
    <string>1</string>
    <string>2</string>
    <string>3</string>
    <string>4</string>
    <string>5</string>
</array>
</plist>

Answer 1

change ascending:NO to ascending:YES when creating the sort descriptor.

To provide any more advice you'd probably need to post more code. You should post how you're actually populating the data structure which acts as your data source, and how you are using that data structure in cellForRowAtIndexPath .

Answer 2

Format your data like this (note that you can do this by creating a .plist with an array in it)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>Title of Array</key>
    <array>
        <string>1</string>
        <string>2</string>
        <string>3</string>
        <string>4</string>
        <string>5</string>
    </array>
</dict>
</plist>

Then use this code to get it

NSDictionary *data = [[NSDictionary alloc] initWithContentsOfFile:DataPath];
NSArray *array = [[names allKeys] sortedArrayUsingSelector:@selector(compare:)];
