此函数存储第一个值并返回相同的消息。
我尝试过这个:
FileManager.default.clearTmpDirectory()
let resultt:NSDictionary = dict! as NSDictionary
//let topup = resultt.value(forKeyPath: "Body.QR_TopupResponse.QR_TopupResult") as! String
func getdata () -> String{
guard let body = resultt["Body"] as? [String: Any] else {
// Failed to find body, return empty string
return ""
}
guard let response = body["QR_TopResponse"] as? [String: Any] else {
return ""
}
guard let result = response["QR_ToResult"] as? String else {
return ""
}
return result
}
print(getdata())
self.presentAlert(withTitle: "", message: getdata())
or ..
var ftsm = resultsm.value(forKeyPath:
"Body.QR_TOPResponse.QR_TOPResult") as! String
// How to remove keypath.
答案 0 :(得分:0)
要清除字典数据,您应该尝试:
myDictionary.removeAll()
或者您也可以尝试:
源自NSDictionary的removeAllObjects
的{{1}}方法
NSMutableDictionary
因此,调用[myDictionary removeAllObjects];
[myDictionary release];
myDictionary = [[NSMutableDictionary alloc] init];
将清空字典并释放所有包含的对象。
