How do I remove all objects from an NSMutableArray?

I need to remove all objects from an NSMutableArray. I can't seem to do this by enumerating as the code crashes.

Can anyone tell me the best way to do this with a code example if possible?

1.Create instance of NSMutableArray in .h file

@property (strong, nonatomic) NSMutableArray* arrayEmployee;

2.@synthesize in .m file

@synthesize arrayEmployee;

3.Remove all objects from an NSMutableArray

[self.arrayEmployee removeAllObjects];

in case [YourArray removeAllObjects]; doesn't work.

Then do it manually as below:

int c = (int)[YourArray count]-1;
for (int l = 0; l <= c; l++) {[YourArray removeObjectAtIndex:0];}

This should do the trick: 

[myArray removeAllObjects];
