ios 使用webview播放视频需注意

videoWeb是个webView
#pragma mark UITableViewDelegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

videoWeb = [[UIWebView alloc] initWithFrame:CGRectMake(10,0,3,2)];
videoWeb.hidden =NO;
videoWeb.delegate =self;
[self.view addSubview:videoWeb];

excellentModel.urlArr 里面是视频的url数组

NSURL *url = [NSURL URLWithString:[excellentModel.urlArr
objectAtIndex:indexPath.row]];//创建URL
NSURLRequest* request = [NSURLRequest requestWithURL:url];
[videoWeb
loadRequest:request];
}

#pragma mark UIWebDelegate
- (void)webViewDidFinishLoad:(UIWebView *)webView{
videoWeb =nil;
}
