UIWebView属性及方法

UIWebView代理

@property (nullable, nonatomic, assign) id  delegate;

UIWebView代理方方法

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType;
- (void)webViewDidStartLoad:(UIWebView *)webView;
- (void)webViewDidFinishLoad:(UIWebView *)webView;
- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error;

web请求数据及加载数据

- (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;

loadRequest方法：这是加
载网页最常用的一种方式，通过一个网页URL来进行加载，这个URL可以是远程的也可以是本地的

loadHTMLString方法：这个方法需要将html文件读取为字符串

web执行JS代码(OC调用JS的代码)

- (nullable NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script;

缩放内容

@property (nonatomic) BOOL scalesPageToFit;

网页内容转化为可点击链接

使用UIDataDetectorTypes将电话，网址，邮件变为链接

@property (nonatomic) UIDataDetectorTypes dataDetectorTypes NS_AVAILABLE_IOS(3_0);
typedef NS_OPTIONS(NSUInteger, UIDataDetectorTypes) {
    UIDataDetectorTypePhoneNumber                                        = 1 << 0, // Phone number detection
    UIDataDetectorTypeLink                                               = 1 << 1, // URL detection
    UIDataDetectorTypeAddress NS_ENUM_AVAILABLE_IOS(4_0)                 = 1 << 2, // Street address detection
    UIDataDetectorTypeCalendarEvent NS_ENUM_AVAILABLE_IOS(4_0)           = 1 << 3, // Event detection
    UIDataDetectorTypeShipmentTrackingNumber NS_ENUM_AVAILABLE_IOS(10_0) = 1 << 4, // Shipment tracking number detection
    UIDataDetectorTypeFlightNumber NS_ENUM_AVAILABLE_IOS(10_0)           = 1 << 5, // Flight number detection
    UIDataDetectorTypeLookupSuggestion NS_ENUM_AVAILABLE_IOS(10_0)       = 1 << 6, // Information users may want to look up

    UIDataDetectorTypeNone          = 0,               // Disable detection
    UIDataDetectorTypeAll           = NSUIntegerMax    // Enable all types, including types that may be added later
} __TVOS_PROHIBITED;

实例：

 UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(20, 20, 280, 200)];
    textView.dataDetectorTypes = UIDataDetectorTypeAll;
    textView.font = [UIFont systemFontOfSize:20];
    textView.editable = NO;
    textView.text = @"My phone number is +8602980000000.\r\n"
    "My personal web site www.xxxxxx.com.\r\n"
    "My E-mail address is [email protected].\r\n"
    "I was born in 1900-01-01.";
    [self.view addSubview:textView];!

网页播放器

@property (nonatomic) BOOL allowsInlineMediaPlayback ; // iPhone Safari defaults to NO. iPad Safari defaults to YES
@property (nonatomic) BOOL mediaPlaybackRequiresUserAction ; // iPhone and iPad Safari both default to YES

@property (nonatomic) BOOL mediaPlaybackAllowsAirPlay ; // iPhone and iPad Safari both default to YES

allowsInlineMediaPlayback：默认使NO。这个值决定了用内嵌HTML5播放视频还是用本地的全屏控制。为了内嵌视频播放，不仅仅需要在这个页面上设置这个属性，还必须的是在HTML中的video元素必须包含webkit-playsinline属性。
mediaPlaybackRequiresUserAction：在iPhone和iPad上默认使YES。这个值决定了HTML5视频可以自动播放还是需要用户去启动播放

分页模式

@property (nonatomic) UIWebPaginationMode paginationMode ;

typedef NS_ENUM(NSInteger, UIWebPaginationMode) {
    UIWebPaginationModeUnpaginated,
    UIWebPaginationModeLeftToRight,   从左往右分页显示
    UIWebPaginationModeTopToBottom, 从上往下分页显示
    UIWebPaginationModeBottomToTop, 从下往上分页显示，倒着显示
    UIWebPaginationModeRightToLeft  从右往左分页显示
} __TVOS_PROHIBITED;

分页 长度 页面之间差值 分页个数

分页的长度
@property (nonatomic) CGFloat pageLength ;
多个页面之间的差值
@property (nonatomic) CGFloat gapBetweenPages ;
分页的个数
@property (nonatomic, readonly) NSUInteger pageCount ;

是否网页内容下载完毕才开始渲染web视图，默认为NO

@property (nonatomic) BOOL suppressesIncrementalRendering NS_AVAILABLE_IOS(6_0); // iPhone and iPad Safari both default to NO

设置用户交互模式，默认YES

@property (nonatomic) BOOL keyboardDisplayRequiresUserAction NS_AVAILABLE_IOS(6_0); // default is YES
