Cordova/PhoneGapp App Memory Issues

Question

I am developing a hybrid app using Cordova, the app works great on all devices, except for iPad's. The app is map centric, meaning the whole view is taken up by a map box map. When a user zooms in and out at even a little bit Xcode fires off a memory warning, do this more the a few times and the app will crash. I tried using

[[NSURLCache sharedURLCache] removeAllCachedResponses];

in the "did receive memory warning" method, which seems to fix the problem for a while, but as development has continued the issue has crept back in.

Has anybody else seen this issue?

Answer 1

you can try this to see if it helps any.

In AppDelegate.m init method, add...

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
    cacheSizeMemory *= 2; (or 1.5, etc. ... test to see what works best)
    cacheSizeDisk *= 2; (or 1.5, etc. ... test to see what works best)
}

after the cache sizes are set.

UPDATE:

Here's a sample init:

- (id)init
{
    NSHTTPCookieStorage* cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
    [cookieStorage setCookieAcceptPolicy:NSHTTPCookieAcceptPolicyAlways];

    int cacheSizeMemory = 8 * 1024 * 1024; // 8MB
    int cacheSizeDisk = 32 * 1024 * 1024; // 32MB

    if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPad) {
         cacheSizeMemory *= 2;
         cacheSizeDisk *= 2;
    }

#if __has_feature(objc_arc)
    NSURLCache* sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:cacheSizeMemory diskCapacity:cacheSizeDisk diskPath:@"nsurlcache"];
#else
    NSURLCache* sharedCache = [[[NSURLCache alloc] initWithMemoryCapacity:cacheSizeMemory diskCapacity:cacheSizeDisk diskPath:@"nsurlcache"] autorelease];
#endif
    [NSURLCache setSharedURLCache:sharedCache];

    self = [super init];
    return self;
}
