Coco2d 2.1 and Xcode 7 iOS 9 crash ccShader

Question

I tested Xcode 7 with but my cocos2d 2.1 games crash on simulator or on devices:

ccShader_PositionColorLenghtTexture_frag.h

Answer 1

The accepted answer did not work for me, but this did.

Go to the file named CCGLProgram.m

Replace the entire method named - (BOOL)compileShader:(CLuint *)shader type(GLenum)typebyteArray:(const GLchar *)source

with this method

#define _IPHONE9_0 [[[UIDevice currentDevice] systemVersion] floatValue] == 9.000

#define EXTENSION_STRING "#extension GL_OES_standard_derivatives : enable"
static NSString * g_extensionStr = @EXTENSION_STRING;


- (BOOL)compileShader:(GLuint *)shader type:(GLenum)type byteArray:(const GLchar *)source
{
GLint status;
if (!source)
    return NO;


#ifdef _IPHONE9_0

NSLog(@"USING IOS9 shaders");
// BEGIN workaround for Xcode 7 ios9----
BOOL hasExtension = NO;
NSString *sourceStr = [NSString stringWithUTF8String:source];
if([sourceStr containsString:g_extensionStr]) {
    hasExtension = YES;
    NSArray *strs = [sourceStr componentsSeparatedByString:g_extensionStr];
    assert(strs.count == 2);
    sourceStr = [strs componentsJoinedByString:@"\n"];
    source = (GLchar *)[sourceStr UTF8String];
}

const GLchar *sources[] = {
    (hasExtension ? EXTENSION_STRING "\n" : ""),
#ifdef __CC_PLATFORM_IOS
    (type == GL_VERTEX_SHADER ? "precision highp float;\n" : "precision mediump float;\n"),

    source,
