One very common pattern when implementing Objective C singleton objects is the sharedInstance method.
Because I was a bit tired of repeating this code in several of my classes I decided to implement a Xcode Code Snippet that can be reused everywhere.
+ (instancetype) sharedInstance {
static id _sharedInstance = nil;
static dispatch_once_t _onceToken;
dispatch_once(&_onceToken, ^{
_sharedInstance = [[self alloc] init];
});
return _sharedInstance;
}
As you can see simple code that can be apply to any object.
