sectioned UITableView sourced from a pList

I'm having trouble finding a easy to understand tutorial on having a sectioned UITableView which gets its data from a pList file.

Things im having trouble with, is how to properly structure the pList file to cater for 2 different section开发者_运维技巧s.

---

The root of the plist should be an array. The array should contain two dictionaries (your sections). The dictionaries will contain two keys: one for section title and one for the rows in the section.

Assuming you read your plist into an NSArray* sections, you can return the section, row count, section title and cell titles using the code below.

Your plist file would look like this:

<?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>
    <dict>
        <key>Title</key>
        <string>Section1</string>
        <key>Rows</key>
        <array>
            <string>Section1 Item1</string>
            <string>Section1 Item2</string>
        </array>
    </dict>
    <dict>
        <key>Title</key>
        <string>Section2</string>
        <key>Rows</key>
        <array>
            <string>Section2 Item1</string>
            <string>Section2 Item2</string>
        </array>
    </dict>
</array>
</plist>
