在命令行程序中使用NSBundle时,我注意到了一些奇怪的行为.如果,在我的程序中,我使用现有的bundle并制作它的副本,然后尝试使用pathForResource在Resources文件夹中查找某些内容,除非我在程序启动之前查找我正在查找的包,否则总是会返回nil.我创建了一个复制问题的示例应用程序,相关代码是:

int main(int argc, char *argv[]) 
{ 
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
    NSString *exePath = [NSString stringWithCString:argv[0]
                                           encoding:NSASCIIStringEncoding]; 
    NSString *path = [exePath stringByDeletingLastPathComponent]; 
    NSString *templatePath = [path stringByAppendingPathComponent:@"TestApp.app"];

    // This call works because TestApp.app exists before this program is run 
    NSString *resourcePath = [NSBundle pathForResource:@"InfoPlist" 
                                                ofType:@"strings"
                                           inDirectory:templatePath]; 
    NSLog(@"NOCOPY: %@", resourcePath); 

    NSString *copyPath = [path stringByAppendingPathComponent:@"TestAppCopy.app"]; 
    [[NSFileManager defaultManager] removeItemAtPath:copyPath 
                                               error:nil]; 
    if ([[NSFileManager defaultManager] copyItemAtPath:templatePath 
                                                toPath:copyPath 
                                                 error:nil]) 
    { 
        // This call will fail if TestAppCopy.app does not exist before 
        // this …
