Appending data to PLIST - iPhone

Question

we need to be able to read in the contents of an existing plist file then add to the array / dictionary then write this new data to the plist file. The stricture is simple.

Answer 1

You do it like this:

// Get current content.
NSDictionary *oldContent = [NSDictionary dictionaryWithContentsOfFile:plistPath];
// Make a mutable copy.
NSMutableDictionary *newContent = [[oldContent mutableCopy] autorelease];
// Add new stuff.
[newContent setObject:newObject forKey:newKey];
// Now, write the plist:
[newContent writeToFile:plistPath atomically:YES];

There is no need to use NSPropertyListSerialization at all here.
