base64 encoding conversion issue

Question

Here my code for conversion a image,

CGSize newSize1=CGSizeMake(720.00, 576);
self.imageData = [PDFImageConverter convertImageToPDF:image1 withResolution:300 maxBoundsRect:CGRectMake(0, 0, 194, 154) pageSize:newSize1];
largerbtn.selected=YES;
smallerbtn.selected=NO;
CGSize newSize=CGSizeMake(194, 154);
UIGraphicsBeginImageContext(newSize);
[image1 drawInRect:CGRectMake(0,0,newSize.width,newSize.height)];
UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
//NSData *imageData1
imageData1=UIImageJPEGRepresentation(newImage, 1.0);
//NSString *encodedString
encodedString= [Base64 encode:imageData1];//crashed when it reached here
NSLog(@"%@",encodedString);

The application getting crashed when it reaches the base64 conversion,What wrong with my code.Please help me to solve this issue.

Answer 1

   // Use this line 
     imageData1=UIImageJPEGRepresentation(newImage, 1.0);
      NSString *encodedString = [imageData base64Encoding];

Answer 2

Use

 [Base64 initialize];

before using

[Base64 encode:imageData1].

Hope it helps.

Answer 3

you miss initialization of Base64 class as

[Base64 initialize];

include this line, before you try to encode
