iphone - 编程内存警告 ios

Question

我想在低内存条件下测试我的应用程序。以前我的方法是运行

[NSTimer scheduledTimerWithTimeInterval:2.0 target:[UIApplication sharedApplication] selector:@selector(_performMemoryWarning) userInfo:nil repeats:YES];

但它不再起作用了。我所说的工作是指未调用 didReceiveMemoryWarning。我也试过:

 [[NSNotificationCenter defaultCenter] postNotificationName:UIApplicationDidReceiveMemoryWarningNotification object: [UIApplication sharedApplication]]; 
 [[NSNotificationCenter defaultCenter] postNotificationName:UIApplicationDidReceiveMemoryWarningNotification object: nil];
 [[UIApplication sharedApplication] _performMemoryWarning];

但以上似乎都不起作用。

任何想法将不胜感激

看这篇文章 Is there a way to send Memory Warning to iPhone device manually?

以编程方式发送:CFNotificationCenterPostNotification(CFNotificationCenterGetDarwinNotifyCenter(), (CFStringRef)@"UISimulatedMemoryWarningNotification", NULL, NULL, true);

在模拟器中:
