在iOS中创建包含图像数组的单页pdf文件？

我需要在iOS中创建一个包含多个图像的单页pdf文件。 我用这个代码：

- (void)createPDFWithImagesArray:(NSMutableArray *)array andFileName:(NSString *)fileName { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *documentsDirectory = [paths objectAtIndex:0]; NSString *PDFPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.pdf",fileName]]; for (UIImage *image in array) { // Mark the beginning of a new page. CGRect pagebounds=CGRectMake(0, 0, image.size.width, image.size.height); CGRect imagebounds=CGRectMake(0, 0, image.size.width, image.size.height); UIGraphicsBeginPDFContextToFile(PDFPath, pagebounds, nil); { UIGraphicsBeginPDFPage(); [image drawInRect:imagebounds]; } } UIGraphicsEndPDFContext(); } 

但是它没有生成pdf文件并且获取错误可以让任何身体帮助我…
