iOS 关于webView的几种应用

创建一个webView ：UIWebView*_myWebView=[[UIWebViewalloc]initWithFrame:CGRectMake(0,0,self.view.bounds.size.width,self.view.bounds.size.height-48)];

_myWebView.delegate=self;

[self.viewaddSubview:_myWebView];

1. 加载webView不带有绿字横线，取消打电话的功能。  _myWebView.dataDetectorTypes=UIDataDetectorTypeNone;

2.webView 不弹动    _myWebView.scrollView.bounces=NO;

3.加载一个URL 

NSURL* url = [NSURLURLWithString:@"https://www.baidu.com"];//创建URL

NSURLRequest* request = [NSURLRequestrequestWithURL:url];//创建NSURLRequest

[_myWebViewloadRequest:request];//加载

4.加载一个本地的html

（1）.NSString*path = [[NSBundlemainBundle]pathForResource:@"about_12xue_frm"ofType:@"html"];

NSString*htmlString = [NSStringstringWithContentsOfFile:pathencoding:NSUTF8StringEncodingerror:nil];

NSString*basePath = [[NSBundlemainBundle]bundlePath];

NSURL*baseURL = [NSURLfileURLWithPath:basePath];

[_myWebViewloadHTMLString:htmlStringbaseURL:baseURL];   这种是拖入html和图片时选择第一种Create groups。  路径无所谓

（2）Create folder references

这个需要把html放在文件夹里 路径完全需要按照写html的格式，比如拖进去了一个名叫htmlD的文件夹，htmlD里边的关系按相对路径算。

NSURL*url = [NSURL URLWithString:[[NSBundle mainBundle] pathForResource:@"about_12xue_frm"ofType:@"html"inDirectory:@"htmlD"]];

NSURLRequest*request = [NSURLRequest requestWithURL:url];

[_myWebViewloadRequest:request];

5.加载一个的字符串

[_myWebViewloadHTMLString:@"123456789"baseURL:nil];

可配上加载后的代理  

#pragma mark - UIWebViewDelegate

- (void)webViewDidFinishLoad:(UIWebView*)webView

{

NSString*meta = [NSStringstringWithFormat:@"document.getElementsByName(\"viewport\")[0].content = \"width=%f, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no\"",kDeviceWidth];

[webViewstringByEvaluatingJavaScriptFromString:meta];

}
