LCFastSingleton

LCFastSingleton allows you to create singletons by a impressively quick way, and centrally manage them, without needing you to enter any other code.

If you have used this way to create singletons.

static XXX * xx = nil;
if (!xx) {
    xx = [[XXX alloc] init];
}
return xx;

Or this.

static XXX * xx = nil;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
    xx = [[XXX alloc] init];
});
return xx;

Now, You can discard all of those methods and use LCFastSingleton.

DemoConfig.singleton.id = @(1);
DemoConfig.singleton.type = @(2);
DemoConfig.singleton.name = @"3";

NSLog(@"DemoConfig singleton: id=%@, type=%@, name=%@", DemoConfig.singleton.id, DemoConfig.singleton.type, DemoConfig.singleton.name);

Safety LCFastSingleton.

DemoConfig * newDemoConfig = [[DemoConfig alloc] init];
// The singleton is safe if the pointer same.
NSLog(@"LCS P: %p Alloc newDemoConfig P:%p", DemoConfig.singleton, newDemoConfig);

You can also custom the method name on .h file. (Such as DemoConfig.XXSingleton.id)

#define LC_SINGLETON_CUSTOM_METHOD_NAME singleton // You can custom the method name, for example: "singleton".

You can also open the protocol verify on .h file.

#define LC_SINGLETON_PROTOCOL_VERIFY YES
