Question

I am using protocol,and getting leak,
Here is my code :

+ (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;
}

if I do autorelease then it will be crashed.so what should I do now?please help me…
Thank You…

Answer 1

In your strategyFromType function

return [strategy autorelease];

When you call this function use retain

GMGridViewLayoutStrategy *strat = [[YourClassName strategyFromType:yourType] retain];

After use of strat variable

[strat release];
