Question

How to use local static objects in Objective-C?

- (void)foo {
    static NSMutableArray *mutableArr = nil;
    // initialize mutableArr somehow somewhere 
    // using mutableArr several times
}

Answer 1

I hope I’m not missing anything, but this is how I’m using it:

- (void)foo {
    static NSMutableArray *mutableArr = nil;
    if (mutableArr == nil) {
        mutableArr = [[NSMutableArray alloc] init...];
        // add more first time initialization as required
    }
    assert(mutableArr);
    // now, use mutableArr freely...
}
