Interlocked operations in iOS?

Question

Are there interlocked(atomic) operations in iOS SDK?

I need interlocked increment\\decrement and interlocked comparsion.

*UPDATE: * My main proble

Answer 1

Objective-C has the keyword synchronized for atomic operations.

@synchronized(object) {
    // ...
}

If you specify the attribute atomic in a property declaration, the setters and getters will be sythesized using these synchronized-blocks.

Also look at NSLock and NSLocking protocol.
