我想显示每个单元格都包含嵌套 UIview 的表格视图，但我遇到了一些问题。
1) 当我尝试滚动表格视图时，我的应用程序崩溃。
通过将根视图而不是子视图添加到应用程序委托中来解决
现在问题2
2）我想在表格单元格中添加水平滚动视图。所以我可以在单个单元格中显示3个子视图，我可以在单元格中水平滚动..我该怎么做。我想做这个..
为了实现这一点，我有这个代码..
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
UIView *wagon = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 430, 187)];
UIColor *background = [[UIColor alloc] initWithPatternImage:[UIImage imageNamed:@"wagon.png"]];
wagon.backgroundColor = background;
UIScrollView *scrollview = [[UIScrollView alloc]initWithFrame:CGRectMake(0, 0, 830, 187)];
scrollview.showsVerticalScrollIndicator=YES;
scrollview.scrollEnabled=YES;
scrollview.userInteractionEnabled=YES;
UIView *videoview = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 220 , 100)];
UIImageView *video = [[UIImageView alloc]initWithFrame:CGRectMake(wagon.frame.origin.x+18, wagon.frame.origin.y+35, 220, 100)];
UIImage *bgImage = [UIImage imageNamed:@"video.png"];
video.image = bgImage;
videoview.contentMode = UIViewContentModeLeft;
[videoview addSubview:video];
UIView *textview = [[UIView alloc]initWithFrame:CGRectMake(wagon.frame.origin.x+238,wagon.frame.origin.y+28, 150 , 187)];
textview.contentMode = UIViewContentModeRight;
UILabel * label = [[UILabel alloc]initWithFrame:CGRectMake(28,10, 150 , 87)];
label.text=@"This is testing text for IOS app to check line are aligned or not and to check video image and nested views for UIviews";
label.backgroundColor = [UIColor clearColor];
label.textColor=[UIColor redColor];
label.numberOfLines = 4;
[textview addSubview:label];
[wagon addSubview:textview];
[wagon addSubview:videoview];
[scrollview addSubview:wagon];
[self addSubview:scrollview];
}
return self;
}
并从表格单元格中调用此视图
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = @"StateCell";
UITableViewCell *cell;
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Wagon1 *wg=[[Wagon1 alloc]init];
[cell addSubview:wg];
return cell;
}
通过添加 wg，我得到了一个火车 boggi，货车视图.. 我最后或第一个想要 2 个货车视图和引擎。
** 表崩溃问题已解决**
1）为了解决崩溃问题，我在stackoverflow上进行了搜索，我找到了解决方案，例如添加代表或更改为保留或强bla bla ..但这些都不适合我。这是我的代码。还有一件事我不使用 XIB ，笔尖或情节提要..
