问题描述
我有一个名为Announcement
的类,它有一个Title
(NSString
),一个Publishing Date
(NSString
)和一个 Body
(NSString
与 HTML 内容).
I have a class named Announcement
, it has a Title
(NSString
), a Publishing Date
(NSString
) and a Body
(NSString
with HTML content).
我想以与电子邮件应用程序类似的方式显示它.当您阅读电子邮件时,您会看到前三个行"(发件人、收件人、标题[日期]),然后是电子邮件的内容.
I would like to display it in a similar way like in the Email app. When you read an email you have the first three "rows" (From, To, Title[date]) and then the content of the email.
我只想创建Title[date]"行,然后是正文.我想它是一个 UITableView
,在第一个单元格上有我的 Title
,在第二个单元格上有一个 UIWebView
.
I would want to create only the "Title[date]" row and then the body. I imagine that it to be a UITableView
which has on the first cell my Title
and on the second cell an UIWebView
.
但似乎单元格的高度与 UIWebView
的高度完全相同,所以我的问题是:
But it seems like the cell has exactly the height of the UIWebView
, so my question is this:
如何根据我的 Body
计算我的 UIWebView
的高度?因为基本上,当你垂直滚动时,你会滚动整个 UITableView
,而当你水平滚动时,你只会滚动 UIWebView
内容.
How can calculate the height of my UIWebView
depending on my Body
? Because basically when you scroll vertically you scroll the whole UITableView
, and when you scroll horizontally you scroll only the UIWebView
content.
谢谢
推荐答案
在 webview 委托方法中,试试下面的代码:
In webview delegate method, just try with below code:
- (void)webViewDidFinishLoad:(UIWebView *)webView{
[webviewTopicDesc sizeToFit];
[webviewTopicDesc setFrame:CGRectMake(webviewTopicDesc.frame.origin.x, webviewTopicDesc.frame.origin.y, 300.0, webviewTopicDesc.frame.size.height)];
}
在此之前,将 webview 高度设为 5.0.
Before that, make the webview height as 5.0.
希望对您有所帮助.
这里可以根据字符串获取动态高度.
Here, you can get dynamic height based on string.
-(CGSize)getDynemicHeight:(int)pintFixWidth :(NSString *)pstrText
{
CGSize maximumSize=CGSizeMake(pintFixWidth, g_Max_Width);
UIFont *myFont = [UIFont fontWithName:g_Default_Font_Name size:g_Default_Font_Size];// font used for label
myFont=[UIFont boldSystemFontOfSize:g_Default_Font_Size];
CGSize sizeS = [pstrText sizeWithFont:myFont
constrainedToSize:maximumSize
lineBreakMode:UILineBreakModeWordWrap];
sizeS.height=sizeS.height+39;
return sizeS;
}
这里,你必须用字体样式来固定宽度和字体大小.
Here, you have to fix the width and font-size with font-style.
