苹果自带的UIWebView提供了基本的Html访问功能,提供了三种方法:
1 | - (void)loadRequest:(NSURLRequest *)request;- (void)loadHTMLString:(NSString *)string baseURL:(nullable NSURL *)baseURL;- (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)textEncodingName baseURL:(NSURL *)baseURL;

##加载本地Html 方式1:
1 | NSString *resourcePath = [[NSBundle mainBundle] resourcePath]; NSString *filePath =[resourcePath stringByAppendingPathComponent:@ "FlyElephant.html" ]; NSMutableString *htmlstring=[[NSMutableString alloc] initWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; NSURL *baseUrl=[NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]]; [self.webView loadHTMLString:htmlstring baseURL:baseUrl];
|
로그인 후 복사
方式2:
1 | NSString *filePath = [[NSBundle mainBundle]pathForResource:@ "Book" ofType:@ "html" ]; NSString *htmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; [self.webView loadHTMLString:htmlString baseURL:[NSURL URLWithString:filePath]];
|
로그인 후 복사
###加载网络Html 通过loadRequest实现:
1 | NSURL *url = [[NSURL alloc] initWithString:@ "https://www.baidu.com/" ]; [self.webView loadRequest:[NSURLRequest requestWithURL:url]];
|
로그인 후 복사
#加载NSData loadData使用起来也非常简单:
1 | NSString *path = [[NSBundle mainBundle]pathForResource:@ "Book.pdf" ofType:nil];
|
로그인 후 복사
友情提示,如果是新建项目,注意在info.list中添加NSAppTransportSecurity为Dictionary,NSAllowsArbitraryLoads为Boolean:
