UIWebView小結

1.加載URL網頁

- (void)loadWebPageWithString:(NSString *)URLString {
    UIWebView *aWebView = [[UIWebView alloc]initWithFrame:self.view.bounds];
    NSURLRequest *URLRequest = [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:URLString]];

    [aWebView loadRequest:URLRequest];

    aWebView.delegate = self;

    [self.view addSubview:aWebView];

}

調用

[self loadWebPageWithString:@"http://www.baidu.com"];

2.加載本地的html

- (void)loadHTMLWithString {
    UIWebView *aWebView = [[UIWebView alloc] initWithFrame:self.view.bounds];
    NSString *htmlPath = [[NSBundle mainBundle] pathForResource:@"table" ofType:@"html"];
    NSString *htmlString = [NSString stringWithContentsOfFile:htmlPath encoding:NSUTF8StringEncoding error:nil];
    [aWebView loadHTMLString:htmlString baseURL:[NSURL URLWithString:htmlPath]];
    aWebView.delegate = self;
    [self.view addSubview:aWebView];

}

3.以二進制的形式加載文件

- (void)loadLocalFile {
    UIWebView *aWebView = [[UIWebView alloc] initWithFrame:self.view.bounds];
    NSURL *fileURL = [[NSBundle mainBundle] URLForResource:@"names.txt" withExtension:nil];
    NSURLRequest *URLRequest = [NSURLRequest requestWithURL:fileURL];
    NSURLResponse *response = nil;
    NSData *data = [NSURLConnection sendSynchronousRequest:URLRequest returningResponse:&response error:nil];
    [aWebView loadData:data MIMEType:response.MIMEType textEncodingName:@"utf-8" baseURL:fileURL];
    aWebView.delegate = self;
    [self.view addSubview:aWebView];

}
