根據UIWebView
的大小,我在調整UItablecell
時遇到問題。調整大小的UITableCell中的WebView單元問題
當我嘗試調整我Cell
與heightForRowAtIndexPath
方法,它不知道的WebView的大小,因爲它webViewDidFinishLoad
之前運行。我使用webViewDidFinishLoad
調整webView依賴內容的大小。
的cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString * documentsDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) objectAtIndex:0];
static NSString *CellIdentifier = @"OtherCells";
OtherCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[OtherCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
cell.WebView.delegate = self;
NSString *ImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", [NameArray objectAtIndex:indexPath.row] ]];
[cell.WebView loadHTMLString:[NSString stringWithFormat:@"<head><body style=」background-color:transparent」><head><body id=\"foo\">\
<div><img style=\"float:left;width:100px;height:50px;margin-right:10px;margin-bottom:5px;border:1px solid gray;padding:5px;\" src=\"file://%@/\"> <p id=\"test\" style=\"color:rgb(5, 85, 173);font-size:12px;font-family:\"Trebuchet MS\"\"><b>%@</b></p> <p id=\"test2\" style=\"position:relative;top:-7px;font-size:11px;font-family:\"Trebuchet MS\"\">%@ <br><span id=\"time\" style=\"float:right;font-size:10px;\">%@</span></p></div></body>",ImagePath,[TitleArray objectAtIndex:indexPath.row],[SummaryArray objectAtIndex:indexPath.row],[TimeStampArray objectAtIndex:indexPath.row]] baseURL:nil];
return cell;
}
webViewDidFinishLoad
- (void)webViewDidFinishLoad:(UIWebView *)webView
{
OtherCell *cell = (OtherCell *)[[webView superview] superview];
NSString *string = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"test\").offsetHeight;"];
NSString *string2 = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"test2\").offsetHeight;"];
NSString *string3 = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"time\").offsetHeight;"];
CGFloat height = [string floatValue] + [string2 floatValue] +[string3 floatValue]+ 14;
rowHeight=height;
CGRect frame = [webView frame];
frame.size.height = height;
[webView setFrame:frame];
NSLog(@"webViewDidFinishLoad");
//test label after webview
CGRect frame1= [cell.Label frame];
frame1.origin.y = height+2;
[cell.Label setFrame:frame1];
}
您應該避免在'UITableViewCell'中使用'UIWebView'。爲什麼你需要在單元格中查看網頁? – Amar

這可以在沒有Web視圖的情況下完成。看看[這個問題](http://stackoverflow.com/questions/5284516/how-can-i-draw-image-with-text-wrapping-on-ios)及其答案。還有包含解釋的回答者的博客鏈接。 – Amar
