我在应用程序中本地存储了5个.html文件和2个.js文件。
以webviewone和webviewtwo的名义创建了2 UIWebview。在webviewone中加载了第一个html文件。
在webviewone中，设备中的用户屏幕可见。
当用户UIButton操作增加webviewoneindex++
和
调用[self Loadhtminwebviewone];方法。
同时我生成方法（[self Loadhtminwebviewtwo]）。在证明之后计算总长度。
-(void)Loadhtminwebviewone
{
NSString *pagesPath=[array4htmlpath objectAtIndex:webviewoneindex];
NSURL *url=[NSURL fileURLWithPath:pagesPath];
webviewone.delegate=self;
webviewone.scrollView.delegate=self;
webviewone.scrollView.bounces=NO;
webviewone.scrollView.scrollEnabled=NO;
[webviewone loadRequest:[NSURLRequest requestWithURL:url]];
}
-(void)Loadhtminwebviewtwo
{
if(webviewtwoindex==array4htmlpath.count-1)
{
return;
}
NSString *pagesPath=[array4htmlpath objectAtIndex:webviewtwoindex];
NSURL *url=[NSURL fileURLWithPath:pagesPath];
webviewtwo.delegate=self;
webviewtwo.scrollView.delegate=self;
webviewtwo.scrollView.bounces=NO;
webviewtwo.scrollView.scrollEnabled=NO;
[webviewtwo loadRequest:[NSURLRequest requestWithURL:url]];
}
