根据JSON,将打印aarti
数组中的所有值:
According to the JSON this prints all values in the aarti
array:
if let JSON = response.result.value as? [String:Any] {
if let response = JSON["wsResponse"] as? [String:Any],
let aarti = response["aarti"] as? [[String:Any]] {
for item in aarti {
let content = item["content"] as! String
let identifier = item["identifier"] as! String
let title = item["title"] as! Int
let type = item["type"] as! String
print(content, identifier, title, type)
}
}
}
在Swift中基本上不使用NSDictionary / NSArray
.
Basically do not use NSDictionary / NSArray
in Swift.
如果要将所有content
值放入数组中,请使用flatMap
.该行可以代替整个重复循环.
If you want to put all content
values in an array use flatMap
. The line can replace the whole repeat loop.
let contentArray = aarti.flatMap { $0["content"] as? String }
PS:如果要根据值创建多个数组,请不要这样做:使用自定义结构或类
PS: If you are going to create multiple arrays from the values don't do that: Use a custom struct or class
