Send Notification When a Property is Changed Using KVO

Question

I had a property named myName in my class, like:

@property (nonatomic, strong) NSString *myName;

I need to send a notification whe

Answer 1

To do this without the customer setter, just synthesize the property setter. This will create all the supporting calls to willChangeValueForKey / didChangeValueForKey.

@synthesize myName;

Then set property values with dot-syntax:

self.myName = @"Inigo Montoya"

Then the observers will receive the KVO notification automatically.

(You will need to remove the observer before you release the observed object.)
