I have these two errors. I developed a program that works in 10.10 but plant 10.7. I did not test in 10.8 and 10.9. How to correct the problem. I use these two methods for authentication and for something else. How to do ? Rewrite everything? Thank you

Thanks for your help ... and xhruso00 I do not know if I should change my question here and write a new answer ? Thank you

With

#import <Foundation/Foundation.h>


@interface NSString (NSStringExtension)

- (id) base64EncodedStringWithOptions:(NSString *)string;

- (NSString *) base64Encoding;

- (NSString *)mh_base64String;

@end

and

#import "NSStringExtension.h"

@implementation NSString (NSStringExtension)

NSUInteger  NSAppKitVersionNumber10_8;
NSUInteger NSAppKitVersionNumber;

- (NSString *)mh_base64String
{

    if (floor(NSAppKitVersionNumber) <= NSAppKitVersionNumber10_8) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
        return [self base64Encoding];
#pragma clang diagnostic pop
    }
    else {
        return [self base64EncodedStringWithOptions:0];
    }
}

@end

and

in the main 

@implementation  AppDelegate
...  




  //NSString *authenticationValue = [authenticationData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];

  NSString *authenticationValue = [authenticationData mh_base64String];

        ...
        @end

I have one error:

AppDelegate.m:56:57: error: no visible @interface for 'NSData' declares the selector 'mh_base64String' NSString *authenticationValue = [authenticationData mh_base64String];

i have two warning :

    method definition for 'base64EncodedStringWithOptions:' not found 
 method definition for 'base64EncodedStringWithOptions:' not found

is it correct ?

What is the problem ?

Thanks

You have to check what OS X version you are executing you selector

Unrecognized selector base64EncodedStringWithOptions: was introduced in 10.9

/* Create a Base-64 encoded NSString from the receiver's contents using the given options. */ - (NSString *)base64EncodedStringWithOptions:(NSDataBase64EncodingOptions)options NS_AVAILABLE(10_9, 7_0);

  • (NSString *)base64Encoding NS_DEPRECATED(10_6, 10_9, 4_0, 7_0);

Solution A: Create a category for the object that is loading from XIB and call the method instead of "base64EncodedStringWithOptions"

- (NSString *)mh_base64String
{
  if (floor(NSAppKitVersionNumber) <= NSAppKitVersionNumber10_8) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
    return [self base64Encoding];
#pragma clang diagnostic pop
  }
  else {
    return [self base64EncodedStringWithOptions:0];
  }
}

Solution B: If you can't do category then use method swizzling of original implementation with the above implementation.

I added the method in the method directly awakeFromNib as follows and it was ok.

thank you a lot

 - (void) awakeFromNib {
    ...
//NSString *authenticationValue = [authenticationData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];
    //NSString *authenticationValue = [authenticationData base64Encoding];
    NSString *authenticationValue;


    // Teste la version du système et affecte la bonne méthode
     if (floor(NSAppKitVersionNumber) <= NSAppKitVersionNumber10_8) {
#pragma clang diagnostic push
#pragma clang diagnostic ignored "-Wdeprecated-declarations"
     authenticationValue = [authenticationData base64Encoding];
         // NSLog(@"--- <= 10.8 ----   %@", authenticationValue);
#pragma clang diagnostic pop
     }
     else {
     authenticationValue = [authenticationData base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed];
        // NSLog(@"----- >= 10.9 ---- %@", authenticationValue);
     }

    }
