AFNetworking +许多图像视图=崩溃->收到内存警告 [英] AFNetworking + Many imageviews = Crash -> Received memory warning

问题描述

使用AFNetworking我的应用程序从未遇到过问题，因为我希望显示20个imageview，但是现在我的应用程序崩溃了，因为我想将imagewithURL设置为150个Imageviews，如果我评论说这行没事，这是我的代码：

I 've never had problems with my app using AFNetworking, because I had like 20 imageview to show , but now my app crash because I want to set imagewithURL to 150 Imageviews, if I commented that line all is ok, this is my code:

for (int i=0; i< Array.count; i++) {
  UIImageView *imgProd=[[UIImageView alloc] initWithFrame:CGRectMake(margenX, margenY, 220, 330)];
  imgProd.contentMode = UIViewContentModeScaleAspectFill;
  imgProd.clipsToBounds = YES;
  [imgProd setTag:i];
  // dispatch_async(dispatch_get_main_queue(), ^{
  [imgProd setImageWithURL:[NSURL URLWithString: [Array objectAtIndex:i]]];
  // });
  imgProd.userInteractionEnabled = YES;
  UITapGestureRecognizer *tap ... etc etc.
}

我放了一个dispatch_async，但是是同样的问题，请提出一些建议！，谢谢：）

I put a dispatch_async, but is the same problem, please some advices!, thanks :)

推荐答案

您正在创建150个UIImageViews并填充它们使用imagedata破坏了您的内存并导致应用崩溃。

You are creating 150 UIImageViews and are filling them up with imagedata which mess up your memory and crashes your app.

您应该制作一个UITableView或UICollectionView并使用内置的内存处理程序

You should make a UITableView or UICollectionView and use the built in memory handler

dequeueReusableCellWithReuseIdentifier

dequeueReusableCellWithReuseIdentifier

，以在屏幕上显示图像并在单元格中仅重复使用一个相同的UIImageView。不创建150个uiimageviews，即只需要一个。

, to show the images on the screen and reuse only one and the same UIImageView in the cell. Not create 150 uiimageviews that is, only one is needed.
