Draw a mask image like Left-3 to blend a rounded corner:

func UIGraphicsDrawAntiRoundedCornerImageWithRadius(radius: CGFloat, outerSize: CGSize, innerSize: CGSize, fillColor: UIColor) -> UIImage{  
    UIGraphicsBeginImageContextWithOptions(outerSize, false, UIScreen.mainScreen().scale)
    let currentContext = UIGraphicsGetCurrentContext()

let bezierPath = UIBezierPath()

    if (sqlite3_value_type(argv[0]) == SQLITE_TEXT) {
        
        const unsigned char *a = sqlite3_value_text(argv[0]);

        CFStringRef bs = CFStringCreateWithCString(nil, (const char*)b, kCFStringEncodingUTF8);

###规范
1. 方法只使用一级缩进。
 1. 全部符合要求
 1. 大部分通过方法提取做到，有的带yield的语句块不好提取，幸好一些Linq方法可以用来抽象一些集合操作。
 1. 所有方法都尽量控制在5行以内，不包含空行和括号单独占的行
