Ambiguous reference to member 'count'
提问by Rahul Mathur
Getting the following error when i migrated my current Xcode (v 7.0.1) project to Xcode 7.1.1
当我将当前的 Xcode (v 7.0.1) 项目迁移到 Xcode 7.1.1 时出现以下错误
- Ambiguous reference to member 'count'
- Cannot subscript a value of type 'Array'
- 对成员“计数”的不明确引用
- 不能为“数组”类型的值添加下标
Any idea how to resolve above errors?
知道如何解决上述错误吗?
My code is as follows
我的代码如下
var arrOfRewardDetail : Array = [Dictionary<String, String>]()
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return arrOfRewardDetail.count //Ambiguous reference to member 'count'
}
if self.arrOfRewardDetail[indexPath.row]["KEY"] == "Promotion By : "{} // Cannot subscript a value of type 'Array'
UpdateNow getting the following errors
立即更新出现以下错误
- Ambiguous reference to member 'indexOf'
let indexOfEnum : Int = self.arrPromitionDetailEnum.indexOf(dictRewardInfo["r_promotion_detail_type"]!)!
- Also this one
let indexOfEnum : Int = self.arrPromitionDetailEnum.indexOf(dictInfo["r_promotion_detail_type"]!)! // Cannot subscript a value of type 'Array'
- 对成员“indexOf”的不明确引用
let indexOfEnum : Int = self.arrPromitionDetailEnum.indexOf(dictRewardInfo["r_promotion_detail_type"]!)!
- 还有这个
let indexOfEnum : Int = self.arrPromitionDetailEnum.indexOf(dictInfo["r_promotion_detail_type"]!)! // Cannot subscript a value of type 'Array'

Just remove the : Array
part:
只需删除: Array
部分:
var arrOfRewardDetail = [Dictionary<String, String>]()
The compiler will infer the right type, which is [Dictionary<String, String>]
, not just Array
.
编译器将推断正确的类型,即[Dictionary<String, String>]
,而不仅仅是Array
.
