As the title suggests, what is the default value of the maxConcurrentOperationCount for NSOperationQueue?
Is it set to a value of 1?
From the documentation,
The maximum number of concurrent operations set explicitly on the receiver using the setMaxConcurrentOperationCount: method. If no value has been explicitly set, this method returns NSOperationQueueDefaultMaxConcurrentOperationCount by default.
So it is NSOperationQueueDefaultMaxConcurrentOperationCount
. If this is set, it will choose an appropriate value based on the number of available processors and other relevant factors.
This is how it is defined:
enum {
NSOperationQueueDefaultMaxConcurrentOperationCount = -1
};
NSOperationQueueDefaultMaxConcurrentOperationCount: The default maximum number of operations is determined dynamically by the NSOperationQueue object based on current system conditions.
