Question

I am new to iPhone Development.

+ (id<GMGridViewLayoutStrategy>)strategyFromType:(GMGridViewLayoutStrategyType)type
{
    id<GMGridViewLayoutStrategy> strategy = nil;

    switch (type) {
        case GMGridViewLayoutVertical:
            strategy = [[GMGridViewLayoutVerticalStrategy alloc] init];
            break;
        case GMGridViewLayoutHorizontal:
            strategy = [[GMGridViewLayoutHorizontalStrategy alloc] init];
            break;
        case GMGridViewLayoutHorizontalPagedLTR:
            strategy = [[GMGridViewLayoutHorizontalPagedLTRStrategy alloc] init];
            break;
        case GMGridViewLayoutHorizontalPagedTTB:
            strategy = [[GMGridViewLayoutHorizontalPagedTTBStrategy alloc] init];
            break;
    }

    return strategy;
}

Here I am calling that method:

gmGridView = [[GMGridView alloc] init];
gmGridView.layoutStrategy = [GMGridViewLayoutStrategyFactory strategyFromType:GMGridViewLayoutHorizontalPagedLTR];
[self.view addSubview:gmGridView];

Now my question is that how to release strategy object of strategyFromType method?Its giving me potential leak.and if i am going to release/autorelease,my application is crashing.
Please help meThanking you…

Answer 1

return [strategy autorelease];

UPDATE:
The answer about returning an autoreleased object is correct, the problem is that the GMGridView uses ARC according to the description in the project’s site.

Requirements:

iOS 4 and up
Xcode 4.2 (GMGridView uses ARC)
Frameworks: Foundation,
UIKit, CoreGraphics and QuartzCore

So i suppose you need to add it the project as sub module, but you can search a little about instructions…
