在xCode中工作一切正常如果我通过在工作目录中双击项目而不是从xCode本身执行构建和运行来执行。然后找不到正确的数据库。
如何修改......
sqlite3_open("Airports.sqlite", &db);
所以它可以在当前工作目录中找到Airports.sqlite吗?
答案 0 :(得分:0)
将数据库复制到应用程序目录,之后可以使用数据库:)
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory , NSUserDomainMask, YES);
NSString *dbPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"Airports.sqlite"];
BOOL success = [fileManager fileExistsAtPath:dbPath];
if (!succes){
NSString *defaultDBPath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"Airports.sqlite"];
BOOL success = [fileManager copyItemAtPath:defaultDBPath toPath:dbPath error:&error];
if (!success)
NSAssert1(0, @"Failed to create writable database file with message '%@'.", [error localizedDescription]);
else
NSLog(@"Succesfully created writable database");
}
