Ios Cocos3D崩溃了，它说它不能加载纹理,ios,3d,cocos3d,Ios,3d,Cocos3d,我必须下载一个.pod文件和一个包含纹理图像的文件夹。 之后，我必须加载pod文件，我会看到一个漂亮的3D图像 //podNr is the id of the pod.

我必须下载一个.pod文件和一个包含纹理图像的文件夹。 之后，我必须加载pod文件，我会看到一个漂亮的3D图像

//podNr is the id of the pod.
NSString *url2 = @"http://(MY URL FOR POD FILE);
NSString *urlIm2 = @"http:(MY URL FOR TEXTURE FOLDER);

NSURL *Url = [NSURL URLWithString:url2];
NSURL *UrlIm = [NSURL URLWithString:urlIm2];

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString  *documentsDirectory = [paths objectAtIndex:0];
NSString *podFile = [NSString stringWithFormat:@"PODFILE%d.pod",podNr];


NSString *filePath = [documentsDirectory stringByAppendingPathComponent:podFile];

NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"/images"];

if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
    [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil]; //Create folder

NSMutableData *urlData = [NSMutableData dataWithContentsOfURL:Url];

NSMutableData *urlImageData = [NSMutableData dataWithContentsOfURL:UrlIm];

NSString *folder = [NSString stringWithContentsOfURL:UrlIm encoding:NSUTF8StringEncoding error:nil];

}


NSLog(@"urlIMAGE:%d",[urlImageData length]);


[urlData writeToFile:filePath atomically:YES];

NSLog(@"sucsesfully written to file:%d",[urlData length]);


[self addContentFromPODFile: filePath];
以下是addImages函数的代码：

-(NSMutableArray*) getImages:(NSString *)html andpodNr:(int)podNr
{
NSMutableArray *outPut = [NSMutableArray alloc];
NSString *S = html;
NSString *rest;

while(TRUE)
{
    if ([S rangeOfString:@".jpg\""].location == NSNotFound) {
        return outPut;
    }
    else {
        //existe .jpg!

        int jpgPos = 0;

        int rangeOfCom = 0;
        NSString *auxS = S;

        while (TRUE) {
            jpgPos = [auxS rangeOfString:@".jpg\""].location;
            rangeOfCom = [auxS rangeOfString:@"\""].location;
            if (rangeOfCom == NSNotFound) {
                return outPut;
            }
            if (rangeOfCom > jpgPos) {
                break;
            }
            else {
                auxS = [auxS substringFromIndex:rangeOfCom+1];
            }
        }
        NSString *result = [auxS substringToIndex:rangeOfCom];
        rest = [auxS substringFromIndex:rangeOfCom+1];
        NSLog(@"RESULT:%@",result);

        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString  *documentsDirectory = [paths objectAtIndex:0];

        NSString *newResult = [result stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

        NSString *newPath = [NSString stringWithFormat:@"/images/%@",newResult];

        NSString *filePath = [documentsDirectory stringByAppendingPathComponent:newPath];

        NSString *urlIm2 = @"http://(MY URL FOR IMAGES);
        NSLog(@"URL:%@",urlIm2);
        NSURL *urlA = [NSURL URLWithString:urlIm2];
        NSMutableData *imgData = [NSMutableData dataWithContentsOfURL:urlA];
        [imgData writeToFile:filePath atomically:YES];

        NSLog(@"Written %d to %@",[[NSMutableData dataWithContentsOfFile:filePath] length],filePath);
    }
    S = rest;
}

return outPut;
以下是输出：

所以有几件事。。正如你所看到的，上面写着 已成功写入文件：21600 所以它是下载和写东西。。。 模拟器只是崩溃了。 有什么想法吗？如果需要，请询问其他信息。
事先非常感谢，我很抱歉发了这么长的帖子。

UIImage对象为零似乎出了问题。这会发生在addContentFromPODFile中吗？@Phillip是的，会发生在那里。。奇怪的是，如果纹理的大小太大，例如4096 x 4096，那么它会显示警告：纹理大小太大，支持的大小是2048 x 2048。如果您在代码中查找此项，则警告出现在“UIIMage为nil”事件之后。所以如果它很大，它不是零，但我只是把纹理变小了…创建UIImage对象的代码是什么。。。听起来好像失败了。我不知道UIImage是在哪里创建的。。cocos3d为我做了这件事。。我只需下载所有必要的文件，然后调用addContentFromPODFile.UPDATE：我将UIImage的创建追溯到CC3TextCache，在那里调用了“addImage”方法。我创建了一个新函数addImage2，与第一个函数相同，只是替换了NSString*fullpath=[CCFileUtils fullPathFromRelativePath:path]；对于简单的NSString*fullpath=path，因为我现在给出的路径是绝对的，所以它是这样的：path:/Users/demianschkolnikmuller/Library/Application Support/iPhone Simulator/4.2/Applications/685E679A-E6D9-4834-952E-9158BB37C2B9/Documents/images/wood%202.jpg现在控制台显示没有错误。。但应用程序还是崩溃了=/
