我创建了一个生成PDF的应用程序并将其保存到NSDocumentDirectory。我想让用户很容易找到文件并显示它或使用他们的iPhone打印它。如何找到此文件并轻松查看?
以下是我用来创建PDF的代码:
//USE PDFGENERATOR TO CREATE A PDF FILE
PDFViewController* pdf = [[PDFViewController alloc] init];
NSString *header = lblTitle.text;
NSLog(@"fullQuote=%@", header);
NSString *body = [NSString stringWithFormat:@"%@ \n\n - LRH \n %@", lblExcerpt.text, lblDesc2.text];
NSLog(@"fullQuote=%@", body);
pageSize = CGSizeMake(612, 792);
NSString *fileName = [NSString stringWithFormat:@"%@.pdf", lblTitle.text];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[pdf generatePdf :pdfFileName:header:body:nil];

有一个很好的教程here,它演示了如何在应用程序中打开 .pdf,.xls 文件。
您必须引用的主要类是QLPreviewController
。 here
这是您必须为此
调用的数据源方法- (id <QLPreviewItem>)previewController: (QLPreviewController *)controller previewItemAtIndex:(NSInteger)index
{
// Break the path into it's components (filename and extension)
NSArray *fileComponents = [[arrayOfDocuments objectAtIndex: index] componentsSeparatedByString:@"."];
// Use the filename (index 0) and the extension (index 1) to get path
NSString *path = [[NSBundle mainBundle] pathForResource:[fileComponents objectAtIndex:0] ofType:[fileComponents objectAtIndex:1]];
return [NSURL fileURLWithPath:path];
}
