它将代表整数的字符串转换为其Int值。我正在寻找类似的东西,使用十六进制字符串。我知道这很容易实现,但是如果Swift已经有了,那就更好了。否则,如果您已经对String和Int进行了扩展以实现以下目的:let anHex = "0xA0" if let anInt = anHex.toInt() { println(anInt) // prints 128
//十六进制String转整数var res:UInt32=0NSScanner.localizedScannerWithString(str).scanHexInt(&res) 当然,这个用起来就要麻烦许多,类似的一堆API: NSScanner.localizedScannerWithString(str).scanInt(&res)NSScanner.localizedScannerWithString(str).scanFloat(&res)NSScanner.localizedScannerWithString(str).scanD...

首先，如果你想把一个字符串的指针传递给一个接受UnsafePointer<Int8>的函数，你可以简单地做：

十六进制转换为十进制(string-->int、int-->int) 方法一: System.Convert.ToString(0xa,10);// 以0XA为例,输出为10 或者 System.Convert.ToInt32("0x41", 16);//以"0x41"为例,输出为65 方法二: System.Int32.Parse(s, System.Globalization.NumberStyles.HexNumber);//s为string类型,以“41”为例...
