我请求您帮助解决我的应用程序中的内存问题!
我在表格中有一个单元格,其中包含一个或多个EGOImageView
s 的水平滚动视图。此单元格始终位于第 0 行,但我经常不得不用另一个图像重新加载此单元格。
问题是:当我重新加载我的手机太多次(30 或 40 次)时,我会收到内存警告或有时没有错误并且应用程序崩溃......
我使用 ARC 模组。这是我的代码的预览:
单元格代码
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier animated:(BOOL)animated{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
// Initialization code
[self.contentView setFrame:CGRectMake(0, 0, 320, 240)];
self.scrollView = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 320, 240)];
[self.scrollView setDelegate:self];
[self.scrollView setPagingEnabled:YES];
[self.scrollView setShowsHorizontalScrollIndicator:NO];
self.scrollView.contentSize = CGSizeMake(320, 240);
pageControl = [[UIPageControl alloc]initWithFrame:CGRectMake(0, 220, 320, 20)];
[pageControl setCurrentPage:0];
[self.contentView addSubview:self.scrollView];
[self.contentView addSubview:pageControl];
isAnimated= animated;
return self;
}
- (void)configureGallery:(NSInteger)accommodationId{
counter =0;
Accommodation *item = [[[DataManager sharedManager]accommodations]objectAtIndex:accommodationId];
numberPictures = [[item photo_set]count];
if (numberPictures >1) {
[scrollView setContentSize:CGSizeMake((numberPictures + 2)*320, 240)];
} else [scrollView setContentSize:CGSizeMake(320, 240)];
[pageControl setNumberOfPages:numberPictures];
// add the last image into the first position
if (numberPictures) {
[self addImageWithName:[NSString stringWithFormat:@"%@%@",[[DataManager sharedManager]baseUrl],[[item.photo_set objectAtIndex:numberPictures-1]thumbnail_gallery]] atPosition:0];
}
// add all of the images to the scroll view
for (int i = 0; i < numberPictures; i++) {
[self addImageWithName:[NSString stringWithFormat:@"%@%@",[[DataManager sharedManager]baseUrl],[[item.photo_set objectAtIndex:i]thumbnail_gallery]] atPosition:i+1 ];
}
// add the first image into the last position
[self addImageWithName:[NSString stringWithFormat:@"%@%@",[[DataManager sharedManager]baseUrl],[[item.photo_set objectAtIndex:0]thumbnail_gallery]] atPosition:numberPictures+1];
[self.scrollView scrollRectToVisible:CGRectMake(320,0,320,416) animated:NO];
[self performSelector:@selector(switchToNextPhoto) withObject:nil afterDelay:5];
}
- (void)addImageWithName:(NSString*)imageString atPosition:(int)position {
// add image to scroll view
UIImageView * placeHolderView = [[UIImageView alloc]initWithImage:[UIImage imageNamed:@"France"]];
[placeHolderView setFrame:CGRectMake(position*320, 0, 320, 240)];
UIActivityIndicatorView * activityView = [[UIActivityIndicatorView alloc]initWithFrame:CGRectMake((position*320)+160, 120, 20, 20)];
[activityView startAnimating];
EGOImageView *imageView = [[EGOImageView alloc] init];
imageView.frame = CGRectMake(position*320, 0, 320, 240);
[self.scrollView addSubview:placeHolderView];
[self.scrollView addSubview:activityView];
[self.scrollView addSubview:imageView];
imageView.imageURL = [NSURL URLWithString:imageString];
}
第 0 行的表格代码
GalleryDetailCell *cell = (GalleryDetailCell *) [tableView dequeueReusableCellWithIdentifier: @"GalleryAnimated"];
if (cell == nil) {
cell = [[GalleryDetailCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier: @"GalleryAnimated" animated:animated];
}
[cell configureGallery:id];
cellToReturn = cell;
你知道我的错误在哪里吗?当我重新加载我的手机时,我是否必须手动处理我的EGOImageView
并将它们放入?nil
感谢您的时间!
