- (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:
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];方式2:
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]];###加载网络Html 通过loadRequest实现:
NSURL *url = [[NSURL alloc] initWithString:@"https://www.baidu.com/"]; [self.webView loadRequest:[NSURLRequest requestWithURL:url]];#加载NSData loadData使用起来也非常简单:
NSString *path = [[NSBundle mainBundle]pathForResource:@"Book.pdf" ofType:nil]; //以二进制的形式加载数据 NSData *data = [NSData dataWithContentsOfFile:path]; [self.webView loadData:data MIMEType:@"application/pdf" textEncodingName:@"UTF-8" baseURL:nil];
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:
