我正在尝试将为Mac OS X编写的代码转换为iOS应用程序。这是OS X的工作代码:
// To create the images on the view:
NSRect imageRect = NSMakeRect(24+(i*80), ypos, 72, 96);
NSImageView *theImageView=[[NSImageView alloc] initWithFrame:imageRect];
[theImageView setBounds:imageRect];
[self addSubview:theImageView];
[theImageView setImage:[tCard image]];
[self.imageviews addObject:theImageView];
// To remove the images on the view:
for (NSImageView *timageview in self.imageviews) {
[timageview removeFromSuperview];
}
[self.imageviews removeAllObjects];
目前,我有:
//To create the image on the view
UIImageView * theImageView = [[UIImageView alloc] initWithFrame:CGRectMake(24+(i*80), ypos, 72, 96)];
[self addSubview:theImageView];
[theImageView setImage:[tCard image]];
[self.imageviews addObject:theImageView];
// To remove the images on the view:
for (UIImageView *timageview in self.imageviews) {
[timageview removeFromSuperview];
}
[self.imageviews removeAllObjects];
然而!删除图像不工作。图像在视图上显示正常,但我无法删除它们。说实话,我并不是100%确定示例代码是如何完全正常工作的,但是我正在破解并试图解决它,因此为什么我似乎有点中途,但无法得到要删除的图片:'(

编辑:这是self.imageviews
初始化的方式:
- (id)initWithFrame:(CGRect)frame {
self = [super initWithFrame:frame];
if (self) {
self.imageviews = [[NSMutableArray alloc] initWithCapacity:4];
}
return self;
}
答案 0 :(得分:0)
正如猜测一样,我认为关键是self.imageviews
。我猜你没有初始化它。在某处你应该有类似self.imageviews = [[NSMutableArray alloc] init];
的东西。
