導出文本或pdf

Question

在我的應用程序中，用戶可以將一些信息添加到他的列表中，最後他想通過電子郵件將該列表發送給其他人。我只是想知道如何導出該列表？將它導出爲pdf或txt文件可以嗎？！

好，我用這個代碼，不幸的是我失去了我找到了答案約不引用它很抱歉的頁面。這是魔碼：

-(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, mainView.bounds, nil); 
    UIGraphicsBeginPDFPage(); 
    CGContextRef pdfContext = UIGraphicsGetCurrentContext(); 


    // draws rect to the view and thus this is captured by UIGraphicsBeginPDFContextToData 

    [mainView.layer renderInContext:pdfContext]; 

    // 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); 
}

如果您要搜索iOS5，請檢查this Link。

編輯：使用UIelements這樣的：

[yourView.layer renderInContext:UIGraphicsGetCurrentContext()]
