问题： ios swift string 类型转化为CGfloat给CGRectMake
描述:
解决方案1:
描述:
ios swift string 类型转化为CGfloat给CGRectMake
var currentNodeName:String!
func parser(parser: NSXMLParser, didStartElement elementName: String!, namespaceURI: String!, qualifiedName qName: String!, attributes attributeDict: [NSObject : AnyObject]!)
{
currentNodeName = elementName
if elementName=="background"
{
let stringx = attributeDict["x"]! as String
//if let n = NSNumberFormatter().numberFromString(stringx)
//{
// let x = CGFloat(n)
//}
//var y = attributeDict["y"]! as CGFloat
//var width = attributeDict["width"]! as CGFloat
var Height = attributeDict["Height"]! as String
backgroundRect = CGRectMake(0,0,0,0)
}
}
从xml里面读出来都是string，怎么转换呢？
解决方案1:
atof（str） 这个函数也可以转换出来浮点数的
解决方案2: 笨办法试试
var str = "12.4"
var f = CGFloat ( (str as NSString).floatValue)
绕了八圈转换的，呵呵
