    imageClass.imageString = [[NSString alloc]initWithData:imageData encoding:NSUTF8StringEncoding];
    NSLog(@"String is :%@",imageClass.imageString); // getting NULL

getting String is :null

Answer 1

ImageData can’t directly transfer to NSString,I have a suggestion,you can make this NSData to Base64 NSString,and if you wan’t to covert back,then use Base64 from NSString to NSData,find A “GTMBase64.h”,that will help you

Encode

NSString *imageStr = [GTMBase64 stringByEncodingData:imageData];

Decode

NSData *imageData = [GTMBase64 decodeString:imageStr];
