ios 讀取檔案有兩種方法

下面以讀取TCFexam.db為例

// ---- 方法一 從document裡讀取 ----------//

//    NSArray* paths = NSSearchPathForDirectoriesInDomains( NSDocumentDirectory ,  NSUserDomainMask ,  YES );

//    NSString* documentPath = [ paths objectAtIndex: 0 ];

//    NSString* dbPath = [ documentPath stringByAppendingPathComponent: @"TCFexam.db" ];

    // ---- 方法二
從 資源 裡讀取 ----------//

    NSString* dbPathTwo = [ [
NSBundle mainBundle ] pathForResource:
@"TCFexam" ofType:
@"db" ];

    NSLog( @"two %@" , dbPathTwo );
