我知道这已经被问死了,我向你保证,我已经阅读了我能找到的关于这个主题的每一个线程。到目前为止,没有什么对我有用。这是我到目前为止所拥有的......我知道 2000 的高度有点荒谬,但我试图在 webView 中查看整个帖子。
- (void)viewDidLoad {
// Super
[super viewDidLoad];
_date = [NSDateFormatter localizedStringFromDate:[NSDate date]
dateStyle:NSDateFormatterShortStyle
timeStyle:NSDateFormatterShortStyle];
CGRect frame = _descriptionWebView.frame;
frame.size.width = 320;
frame.size.height = 2000;
_descriptionWebView.frame = frame;
_descriptionWebView = [[UIWebView alloc] initWithFrame:frame];
_descriptionWebView.delegate = self;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
switch (section) {
case 0: return 3;
default: return 1;
}
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// Get cell
static NSString *CellIdentifier = @"CellA";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
cell.textLabel.textColor = [UIColor blackColor];
cell.textLabel.font = [UIFont systemFontOfSize:15];
// Display
switch (indexPath.section) {
case SectionHeader: {
// Header
switch (indexPath.row) {
case SectionHeaderTitle:
cell.textLabel.font = [UIFont boldSystemFontOfSize:15];
cell.textLabel.text = _blogTitle;
cell.textLabel.numberOfLines = 2; // Multiline
break;
case SectionHeaderDate:
cell.textLabel.text = _date;
break;
case SectionHeaderURL:
cell.textLabel.text = [NSString stringWithFormat:@"By %@",_author];
cell.textLabel.textColor = [UIColor grayColor];
break;
}
break;
}
case SectionDetail: {
// Description
NSString* htmlString = _description;
[_descriptionWebView loadHTMLString:htmlString baseURL:nil];
[[cell contentView] addSubview:_descriptionWebView];
_descriptionWebView.scrollView.scrollEnabled = NO;
_descriptionWebView.scalesPageToFit = YES;
}
}
return cell;
}
这是我真正遇到麻烦的部分。我要返回两个不同的高度
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.section == SectionHeaderTitle) {
// Regular
return 54;
} else {
NSInteger height = [[_descriptionWebView stringByEvaluatingJavaScriptFromString:@"document.body.offsetHeight;"] integerValue];
return height;
}
}
我发现了另一个看起来很有希望的帖子......但是,请原谅我,因为我是新手,我无法克服它给我带来的错误。
- (void)webViewDidFinishLoad:(UIWebView *)webView {
CGRect frame = webView.frame;
frame.size = [webView sizeThatFits:CGSizeZero];
frame.size.height += 20.0f; // additional padding to push it off the bottom edge
webView.frame = frame;
webView.delegate = nil;
UITableViewCell *cell =[_cells objectAtIndex:webView.tag];
[cell.contentView addSubview:[_loadingWebView autorelease]];
cell.contentView.frame = frame;
[cell setNeedsLayout];
webView.alpha = 1.0f;
[self.tableView beginUpdates];
NSArray *paths = [NSArray arrayWithObject:[NSIndexPath indexPathForRow:0 inSection:webView.tag]];
[self.tableView insertRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationNone];
[self.tableView endUpdates];
// Storing the currently loading webView in case I need to clean it up
// before it finishes loading.
_loadingWebView = nil;
}
具体来说UITableViewCell *cell =[_cells objectAtIndex:webView.tag];
是给我“'UITableViewCell' 没有可见的@interface 声明选择器'objectAtIndex。
谁能给我一些指导?我已经被这个问题困扰了好几天了。感谢您的阅读,即使您无能为力。
