NSOperation• Abstract superclass• Manages thread creation and lifecycle
• Encapsulate a unit of work in an object• Specify priorities and dependencies
5Wednesday, February 10, 2010
Creating an NSOperation Subclass• Define a custom init method
• Override -main method to do work
- (id)initWithSomeObject:(id)someObject{
self = [super init];if (self) {
self.someObject = someObject;}return self;
}
- (void)main{
[someObject doLotsOfTimeConsumingWork];}
6Wednesday, February 10, 2010
NSOperationQueue• Operations are typically scheduled by adding to a queue• Choose a maximum number of concurrent operations• Queue runs operations based on priority and dependencies
7Wednesday, February 10, 2010
Using an NSInvocationOperation• Concrete subclass of NSOperation• For lightweight tasks where creating a subclass is overkill
- (void)someAction:(id)sender{
NSInvocationOperation *operation = [[NSInvocationOperation alloc] initWithTarget:self selector:@selector(doWork:) object:someObject];
[queue addObject:operation];
[operation release];}

Dismissing a Modal View Controller• Who should do it?• Best practice is for the same object to call present and dismiss
• Define delegate methods for the presented controller■ Tell the delegate when the presented controller is done■ The delegate makes the call to dismiss
