Property lists, or plists are everywhere in iOS and Mac platforms. They are used to store small amounts of data like default settings/preferences. This library attempts to simplify working with them. It encapsulates the functionality needed to save and retrieve data from them.
Plists generally have two kinds of root objects;
NSDictionary. For instance, the
Info.plist in every Xcode project holds an
NSDictionary. When using this library, if the current plist you're working with is empty and does not have a root object type, it will be set when you save any data in it.
Suppose you save an
NSDictionary, that becomes the root object. But if you save any other kind of valid plist object, it will fall back to
NSArray so that any updatation of the plist in future would mean adding objects to that array.
When trying to update an existing plist with root object type
NSDictionary, note that you can only update it with another dictionary. Attempting to update with any other object will fail. On the other hand, an existing
NSArray type plist will be able to update itself with any kind of valid plist object.
CocoaPods is the preferred way to install this library. Add this command to your
- (instancetype)initWithPlistNamed:(NSString *)name NS_DESIGNATED_INITIALIZER;
Use the designated initializer to create an instance. You will also need to provide a valid name for your plist file.
Saves data provided to plist file. This method will overwrite any previous data present in the plist. Returns YES if saving is successful.
save, although this method will not overwrite previous data present in the plist file and append new data after it. Returns YES if saving is successful.
@property (readonly, copy, nonatomic) id plistContents;
Returns the data saved in the plist file.
- (BOOL)deletePlistWithError:(NSError * _Nullable *)error;
You can delete the plist if you're done with it. To recreate, you must initialize another instance of
