我有一个这样的自定义UITableViewCell
// CustomQuestionCell.h
@interface CustomQuestionCell : UITableViewCell {
IBOutlet UIWebView *mywebView;
}
-(void) AssignWebView:(NSString *) _text;
// CustomQuestionCell.m
-(void) AssignWebView:(NSString *) _text {
[mywebView setDelegate:self];
[mywebView loadHTMLString:_text baseURL:nil];
}
我可以在名为MainViewController的文件中的UITableView中成功使用UITableViewCell. UITableViewCell的delagate是CustomQuestionCell.在MainViewController中,我调用以下代码为UIwebview赋值.
// cellForRowAtIndexPath
//CustomQuestionCel.xib uses the class CustomQuestionCell defined above.
CustomQuestionCell *cell = (CustomQuestionCell *)[tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if(cell == nil) {
[[NSBundle mainBundle] loadNibNamed:@"CustomQuestionCellView" owner:self options:nil];
cell = tblQuestionCell;
}
[cell AssignWebView:[ListOfQuestions objectAtIndex:indexPath.row]];
return cell;
我还在CustomQuestionCell.m中有以下代理代码
- (void)webViewDidFinishLoad:(UIWebView *)aWebView {
CGRect frame = aWebView.frame;
frame.size.height = 1;
aWebView.frame = frame;
CGSize fittingSize = [aWebView sizeThatFits:CGSizeZero];
frame.size = fittingSize;
aWebView.frame = frame;
NSLog(@"webview frame size %f",aWebView.frame.size.height);
[aWebView setOpaque:NO];
[aWebView setBackgroundColor:[UIColor colorWithRed:249.0/255 green:243.0/255 blue:236.0/255 alpha:1.0]];
[activityLoad stopAnimating];
[mywebView setHidden:NO];
}
我的问题是我无法在MainViewController中正确设置单元格的高度,它具有使用自定义单元格“CustomQuestionCell”的tableView.在功能中
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
在MainViewController中如何设置单元格的高度为aWebView.frame.size.height ????
解决方法
最好的方式(我想)是创建一个代表.
CustomQuestionCell.h
@protocol CustomQuestionCellDelegate;
@interface CustomQuestionCell : UITableViewCell {
IBOutlet UIWebView *mywebView;
id <CustomQuestionCellDelegate> *delegate;
}
- (void)checkHeight;
@property (nonatomic,assign) id <CustomQuestionCellDelegate> *delegate;
@end
@protocol CustomQuestionCellDelegate <NSObject>
@optional
- (void)customQuestionCell:(CustomQuestionCell *)cell shouldAssignHeight:(CGFloat)newHeight;
@end
2. CustomQuestionCell.m(webViewDidFinishLoad
