IOS獲取資源路徑

  1. 獲取已經添加到xcode工程中的某一資源文件 file.txt 的路徑

NSString *filePath_= [[NSBundle mainBundle] pathForResource:@"file" ofType:@"txt"];
std::string filePath =std::string([filePath_ UTF8String]);

 

2. 對當前xcode工程開通沙盒權限后，訪問存儲到手機上的某一資源文件夾sources/file.txt的路徑

    NSString *docDir = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject];
    NSString *fileDir = [docDir stringByAppendingPathComponent:@"sources"];
    NSString *filePath = [fileDir stringByAppendingPathComponent:@"file.txt"];

    std::string filePath_=std::string([filePath UTF8String]);
