Answer 3

很简单：-

[*your array name* count];

Answer 4

you have to just check

[array count];

Answer 5

Make sure you declared your value as the correct type or else you will get: Implicit conversion of 'int' to 'x' is disallowed with ARC .

You could this...

num = [yourArray count];

and you'll get Implicit conversion loses integer precision: 'NSUInteger' (aka 'unsigned long') to 'int'

So then you should do this:

num = (int)[allValues count];

Or:

num = (int)allValues.count;
