关于 ios swift string 类型转化为CGfloat给CGRectMake 的问难题
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？

自己找到解决办法了，
let x = CGFloat(((attributeDict["x"]! as String )as NSString).floatValue) let y = CGFloat(((attributeDict["y"]! as String ) as NSString).floatValue) let Width = CGFloat(((attributeDict["Width"]! as String )as NSString).floatValue) let Height = CGFloat(((attributeDict["Height"]! as String ) as NSString).floatValue) m_backgroundRect = CGRectMake(x,y,Width,Height)2019-07-17 19:01:40赞同 展开评论
