15 | [self.layer renderInContext:UIGraphicsGetCurrentContext()]; 16 | UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); 17 | UIGraphicsEndImageContext(); 18 | ``` 19 | 20 | 关键代码：`renderInContext` 是`CALayer`的方法,`CALayer`是CoreGraphic底层的图层, 组成UIView。UIGraphic等相关操作Context是Quartz 2D框架中的API, 而Quartz 2D是CoreGraphic的其中一个组成。 21 | 22 | 这样一个屏幕高度的网页我们就可以保存成图片了，那么多个屏幕的高度呢？思路也很简单，我们先计算出网页的全部可滚动长度 23 | 24 | `self.scrollView.contentSize.height`与屏幕的高度 `self.bounds.size.height` ，利用while循环滚动网页来获取每次Context下的UIImage，存入images集合中: 25 | 26 | ```Objective-C 27 | CGFloat scale = [UIScreen mainScreen].scale; 28 | CGFloat boundsWidth = self.bounds.size.width; 29 | CGFloat boundsHeight = self.bounds.size.height; 30 | CGFloat contentWidth = self.scrollView.contentSize.height; 31 | CGFloat contentHeight = self.scrollView.contentSize.height; 32 | CGPoint offset = self.scrollView.contentOffset; 33 | [self.scrollView setContentOffset:CGPointMake(0, 0)]; 34 | 35 | NSMutableArray *images = [NSMutableArray array]; 36 | while (contentHeight > 0) { 37 | UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, scale); 38 | [self.layer renderInContext:UIGraphicsGetCurrentContext()]; 39 | UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); 40 | UIGraphicsEndImageContext(); 41 | [images addObject:image]; 42 | 43 | CGFloat offsetY = self.scrollView.contentOffset.y; 44 | [self.scrollView setContentOffset:CGPointMake(0, offsetY + boundsHeight)]; 45 | contentHeight -= boundsHeight; 46 | } 47 | 48 | [self.scrollView setContentOffset:offset]; 49 | ``` 50 | 51 | 然后，将图片集合进行拼接，形成一个完整的长图： 52 | 53 | ```Objective-C 54 | CGSize imageSize = CGSizeMake(contentWidth * scale, self.scrollView.contentSize.height * scale); 55 | UIGraphicsBeginImageContext(imageSize); 56 | [images enumerateObjectsUsingBlock:^(UIImage *image, NSUInteger idx, BOOL *stop) { 57 | [image drawInRect:CGRectMake(0,scale * boundsHeight * idx,scale * boundsWidth,scale * boundsHeight)]; 58 | }]; 59 | ``` 60 | 61 | ```Objective-C 62 | UIImage *fullImage = UIGraphicsGetImageFromCurrentImageContext(); 63 | UIGraphicsEndImageContext(); 64 | UIImageView * snapshotView = [[UIImageView alloc] initWithFrame:CGRectMake(rect.origin.x, rect.origin.y, rect.size.width, rect.size.height)]; 65 | snapshotView.image = [fullImage resizableImageWithCapInsets:capInsets]; 66 | ``` 67 | 68 | 完整代码附上： 69 | 70 | ```Objective-C 71 | #pragma mark - UIWebview 滚动生成长图 72 | - (void)ZTUIWebViewScrollCaptureCompletionHandler:(CGRect)rect withCapInsets:(UIEdgeInsets)capInsets completionHandler:(void(^)(UIImage *capturedImage))completionHandler{ 73 | CGFloat scale = [UIScreen mainScreen].scale; 74 | CGFloat boundsWidth = self.bounds.size.width; 75 | CGFloat boundsHeight = self.bounds.size.height; 76 | CGFloat contentWidth = self.scrollView.contentSize.height; 77 | CGFloat contentHeight = self.scrollView.contentSize.height; 78 | CGPoint offset = self.scrollView.contentOffset; 79 | [self.scrollView setContentOffset:CGPointMake(0, 0)]; 80 | 81 | NSMutableArray *images = [NSMutableArray array]; 82 | while (contentHeight > 0) { 83 | UIGraphicsBeginImageContextWithOptions(self.bounds.size, NO, scale); 84 | [self.layer renderInContext:UIGraphicsGetCurrentContext()]; 85 | UIImage *image = UIGraphicsGetImageFromCurrentImageContext(); 86 | UIGraphicsEndImageContext(); 87 | [images addObject:image]; 88 | 89 | CGFloat offsetY = self.scrollView.contentOffset.y; 90 | [self.scrollView setContentOffset:CGPointMake(0, offsetY + boundsHeight)]; 91 | contentHeight -= boundsHeight; 92 | } 93 | 94 | [self.scrollView setContentOffset:offset]; 95 | CGSize imageSize = CGSizeMake(contentWidth * scale, self.scrollView.contentSize.height * scale); 96 | UIGraphicsBeginImageContext(imageSize); 97 | [images enumerateObjectsUsingBlock:^(UIImage *image, NSUInteger idx, BOOL *stop) { 98 | [image drawInRect:CGRectMake(0,scale * boundsHeight * idx,scale * boundsWidth,scale * boundsHeight)]; 99 | }]; 100 | 101 | UIImage *fullImage = UIGraphicsGetImageFromCurrentImageContext(); 102 | UIGraphicsEndImageContext(); 103 | UIImageView * snapshotView = [[UIImageView alloc] initWithFrame:CGRectMake(rect.origin.x, rect.origin.y, 104 | rect.size.width, rect.size.height)]; 105 | snapshotView.image = [fullImage resizableImageWithCapInsets:capInsets]; 106 | completionHandler(snapshotView.image); 107 | } 108 | ``` 109 | 110 | 写完后很高兴，马上实践，UIWebView妥妥的完成目标，然而WKWebView生成的长图最后会有一大段的空白页，造成部分页面丢失，比较如下： 111 | 112 | ![image](https://github.com/BeckWang0912/WZTWebView/blob/master/WZTWebView/Icon/full.png) ![image](https://github.com/BeckWang0912/WZTWebView/blob/master/WZTWebView/Icon/empty.png) 113 | 114 | 如果你用WKWebView使用这个方法，会发现最终截取的只有屏幕上显示的一部分是因为UIWebView与WKWebView渲染机制的不同。WKWebView并不能简单的使用`layer.renderInContext`的方法去绘制图形。如果直接调用`layer.renderInContext`需要获取对应的Context, 但是在WKWebView中执行`UIGraphicsGetCurrentContext()`的返回结果是nil。 115 | 116 | 我做了大量搜索和实践后发现WKWebView中通过直接调用WKWebView的`drawViewHierarchyInRect`方法，可以成功的截取WKWebView的屏幕内容。 117 | 118 | ```Objective-C 119 | - (BOOL)drawViewHierarchyInRect:(CGRect)rect afterScreenUpdates:(BOOL)afterUpdates NS_AVAILABLE_IOS(7_0); 120 | ``` 121 | 122 | 使用时保证afterScreenUpdates = YES 123 | 124 | 完整代码附上： 125 | 126 | ```Objective-C 127 | #pragma mark - WKWebView 滚动生成长图 128 | - (void)ZTWKWebViewScrollCaptureCompletionHandler:(void(^)(UIImage *capturedImage))completionHandler{ 129 | // 制作了一个UIView的副本 130 | UIView *snapShotView = [self snapshotViewAfterScreenUpdates:YES];
