Getting Class Delegates in Time
Today I got to know how to get the delegate methods of a class and when they are incoming. You only have to copy this method into your class and look at the log when the class is initialized / running.
- (BOOL)respondsToSelector:(SEL)aSelector
{
NSString *methodName = NSStringFromSelector(aSelector);
NSLog(@"respondsToSelector: %@", methodName);
return [super respondsToSelector:aSelector];
}
Multithreading in Cocoa ab 10.6
Dies ist die kleinste Möglichkeit in Cocoa asynchron nebenläufigen Code mittels GCD (Grand Central Dispatch) und Blocks zu erzeugen:
dispatch_async(dispatch_queue_create("com.app.task",NULL), ^{
// Do something ...
});
