iOS-加载本地HTML文件

开发过程中登录注册的服务协议一般需要本地加载：
方法如下：
1、加载文件

_webView = [[UIWebView alloc] init];
[self.view addSubview:_webView];
_webView.scrollView.showsVerticalScrollIndicator = NO;
_webView.delegate = self;
NSString* path = [[NSBundle mainBundle] pathForResource:@"服务协议" ofType:@"html"];
NSURLRequest* request = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:path]] ;
[_webView loadRequest:request];

2、加载代码

NSString* path = [[NSBundle mainBundle] pathForResource:@"服务协议" ofType:@"html"];
NSURL *baseURL = [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]];
NSString *html = [NSString stringWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];
[_webView loadHTMLString:html baseURL:baseURL];
