@Property Method: What is 'nonatomic' and 'strong'?
The course for objective-c was very nice, but I did not quite understand what these two parameters in the @property method meant. Could anyone elaborate?
Thank you in advance.
The 'nonatomic' property is the opposite of the default 'atomic' property. A variable with the 'nonatomic' property means that the variable is not thread safe. This might sound scary, but it just means that the variable can be accessed from multiple threads at the same time. The 'atomic' property does not allow this, which makes the 'nonatomic' property faster to use.
The 'strong' property replaced the 'retain' property. The 'strong' property is required when the attribute is a pointer to an object, and it will be retained in memory. The opposite of this is the 'weak' property.
