Ios 在视网膜上加载带有“textureWithContentsOfFile”的纹理显示不工作

我对IOS开发的GLKit有一个奇怪的问题

以下是我的纹理加载程序方法：

(id)initWithFile:(NSString *)fileName effect:(GLKBaseEffect *)effect {
if ((self = [super init])) {
    self.effect = effect;
    NSDictionary * options = [NSDictionary dictionaryWithObjectsAndKeys:
                              [NSNumber numberWithBool:YES],
                                       GLKTextureLoaderOriginBottomLeft,
                              nil];
    NSError * error;
    NSString *path0 = [[NSBundle mainBundle] pathForResource:fileName ofType:nil];
    NSLog(@"Path for Image: %@",path0);
    self.texture0Info = [GLKTextureLoader    textureWithContentsOfFile:path0 options:options error:&error];
    if (self.texture0Info == nil) {
        NSLog(@"Error loading file: %@", [error localizedDescription]);
        return nil;
    }
    TexturedQuad newQuad;
    newQuad.bl.geometryVertex = CGPointMake(0, 0);
    newQuad.br.geometryVertex = CGPointMake(self.texture0Info.width/2, 0);
    newQuad.tl.geometryVertex = CGPointMake(0, self.texture0Info.height/2);
    newQuad.tr.geometryVertex = CGPointMake(self.texture0Info.width/2, self.texture0Info.height/2);

    newQuad.bl.texture0Vertex = CGPointMake(0,1);
    newQuad.br.texture0Vertex = CGPointMake(1,1);
    newQuad.tl.texture0Vertex = CGPointMake(0,0);
    newQuad.tr.texture0Vertex = CGPointMake(1,0);

    self.quad = newQuad;
    self.contentSize=CGSizeMake(self.texture0Info.width, self.texture0Info.height);

}

return self;
}

我从GLKViewController调用这个方法

-(void)addBubbleImage{

SpriteThings * bubbleImage = [[ SpriteThings alloc]initWithFile:@"Rectangler.png" effect:self.effect];
bubbleImage.position=GLKVector2Make(self.view.bounds.origin.x, self.view.bounds.origin.y);
[self.screenThings addObject:bubbleImage];

}

奇怪的是，它在非视网膜显示器上工作，图像加载正确。但在视网膜显示器上，无论是在设备上还是在模拟器上都没有显示任何东西。我有Rectangler.png和Rectangler@2x.png我的项目中的文件位于同一目录中。但还是卡住了。你觉得怎么样？

问题越来越奇怪了。它适用于iPhone4S、iPhone5、iPad2和iPadRetina。而且不适用于iPhone 5s、iPhone 6、iPhone 6 Plus和iPad Air。İOS 7.1和8.1的结果相同。我想我发现了孤独。它与64位体系结构相关。我将所有与CGPoint相关的内容都更改为GLKVector2，并解决了问题。
