Question

在模拟器中，我将从bundle获取obj文件：

NSArray *myArray = [[NSBundle mainBundle] pathsForResourcesOfType:@"obj" inDirectory:nil];

在模拟器中，obj文件按字母顺序打印：

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**banana.obj**,

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**plane3.obj**,

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**wolverine.obj**,

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**Wteapot.obj**,

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**XBODY.obj**,

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**YLID.obj**
)

但是ipad的obj文件没有按字母顺序打印。

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**wolverine.obj,**

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app**/**Wteapot.obj**,**

/Users/name/Library/Application Support/iPhone Simulator/6.0/Applications/10FF2D60-7B33-4AE9-9CA2-95A951A55C49/3DModels.app/**plane3.obj**,

有什么问题？

Answer 1

Apple Document of pathsForResourcesOfType:inDirectory:说：

包含所有捆绑资源的完整路径名的数组匹配指定的标准。此方法返回一个空数组if 找不到匹配的资源文件。

这意味着Apple并没有说它会以任何特定的顺序为您提供路径，但如果您需要它的顺序比您自己排序的那样。

NSArray *sorted = [myArray sortedArrayUsingComparator:^NSComparisonResult(NSString *str1, NSString *str2) 
{
    return [s1 localizedCaseInsensitiveCompare:s2];
}];

所以现在你已经对所有路径的NSArray进行了排序。

Answer 2

我认为你的一些obj文件名起始字符是大写字母。只需更改那些起始字符的文件名是小写字母。

NSArray值改变了ipad与模拟器的顺序？
