Question

我正在尝试从UIView创建一个PDF并且效果很好，就像“How to Convert UIView to PDF within iOS?”那样。
但我的iPad是风景，是一种形式，冗长的形式，高度为3k。
当我转换为PDF时，它只转换iPad的高度大小，即748而不是我需要的3k。

有什么问题？ iOS版本？

编辑：继承人像@wain问的代码

-(void)createPDFfromUIView:(UIView*)aView saveToDocumentsWithFileName:(NSString*)aFilename
{
    // Creates a mutable data object for updating with binary data, like a byte array
    NSMutableData *pdfData = [NSMutableData data];

    // Points the pdf converter to the mutable data object and to the UIView to be converted
    UIGraphicsBeginPDFContextToData(pdfData, aView.bounds, nil);
    UIGraphicsBeginPDFPage();

    // draws rect to the view and thus this is captured by UIGraphicsBeginPDFContextToData
    [aView drawRect:aView.bounds];

    // remove PDF rendering context
    UIGraphicsEndPDFContext();

    // Retrieves the document directories from the iOS device
    NSArray* documentDirectories = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask,YES);

    NSString* documentDirectory = [documentDirectories objectAtIndex:0];
    NSString* documentDirectoryFilename = [documentDirectory stringByAppendingPathComponent:aFilename];

    // instructs the mutable data object to write its context to a file on disk
    [pdfData writeToFile:documentDirectoryFilename atomically:YES];
    NSLog(@"documentDirectoryFileName: %@",documentDirectoryFilename);
}

Answer 1

我从这里找到解决方案“UIGraphicsGetCurrentContext and UIScrollView”并适应我的代码，现在抓住所有表格并打印出漂亮的PDF。如果有人需要我的代码，请告诉我，我发布代码。

在iOS 5.1中从UIView创建PDF格局不起作用
