purgeMemoryForReason攝像頭控制UIImagePickerViewController

Question

我正在開發一個自定義攝像頭控件的小應用程序。

與所有的功能在內存

工作檸良好，沒有任何泄漏，但當我嘗試訪問攝像頭超過8-9倍，應用程序崩潰...

我與性能工具的檢查，但有是沒有內存泄漏有,,, 還住總叮咬4.96 MB僅

我收到以下錯誤......

個直播叮咬少於5 MB還是我得到這個崩潰... 3G和3GS，它變得更加有線... 它崩潰這麼多，他們...多的時候......

任何幫助?????

Answer 1

我有一個類似的問題，我已經建立了一個相機應用程序。我收到很多低內存警告。你在看那些嗎？

作爲一種權宜之計，而我確定我已經把這樣的問題：

 
- (void)didReceiveMemoryWarning { 
    NSLog(@"memory problem!!!!!!!!!!"); 
    NSString *errorString = [NSString stringWithFormat:@"There isn't enough memory to run this app right now. You should quit some apps and try again."]; 
    UIAlertView *errorAlert = [[UIAlertView alloc] initWithTitle:@"Low Memory Warning" message:errorString delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil]; 
    [errorAlert show]; 
    [errorAlert release];  
    [super didReceiveMemoryWarning]; 
}
