我剛從ASIHTTP移動到AFNetworking庫。我還使用Olivier Poitrey和Peter Steinberg的SDURLCache庫。我想緩存我要在我的應用程序中使用的所有圖像。對於這些,我嘗試這樣做:IOS中的AFNetworking Cache圖像中的內存泄漏
NSOperationQueue *queue = [[NSOperationQueue alloc] init];
for(NSURLRequest *imageRequest in imageRequestArray){
AFURLConnectionOperation *operation2 = [[[AFURLConnectionOperation alloc] initWithRequest:imageRequest] autorelease];
[queue addOperation: operation2];
[operation2 waitUntilFinished];
}
當我需要顯示的圖像,我這樣做對每個圖像:
NSURL *url = [NSURL URLWithString:[cat imagePath]];
NSURLRequest *imageRequest = [NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReturnCacheDataElseLoad timeoutInterval:30.0];
AFImageRequestOperation *operation = [AFImageRequestOperation imageRequestOperationWithRequest:imageRequest
imageProcessingBlock:nil
cacheName:@"nscache"
success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){
//NSData *responseData = [request responseData];
imageView.alpha = 0.0;
[imageView setImage:image forState:UIControlStateNormal];
[UIView beginAnimations:@"ToggleViews" context:nil];
[UIView setAnimationDuration:1.0];
imageView.alpha = 1.0;
[UIView commitAnimations];
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){}
];
[operation start];
一段時間後,應用程序使內存警告,然後關閉。爲此,我做了以下內容:
- (void)applicationDidReceiveMemoryWarning:(UIApplication *)application {
[[NSURLCache sharedURLCache] removeAllCachedResponses];
NSLog(@"Memory Warning...");
}
它清除緩存(什麼,我也不是什麼),但一段時間後,再次申請關閉。
我該怎麼做?
我相信我有類似的問題,當我用儀器檢查我的應用程序的內存使用量繼續上升,直到達到約200megs然後該應用程序由於內存警告而終止,我試圖追查問題,似乎沒有任何泄漏 – 2012-04-14 22:37:58
