I have the following JSON and it is validated via JSONLint.com, my only issue is that I can't seem to get all the values out from it.
我有以下JSON，它通过JSONLint.com验证，我唯一的问题是我似乎无法从中获取所有值。
{
"success": true,
"message": null,
"content": [{
"url": "6\/image_2.png",
"date_added": "2015-12-02 22:43:05",
"comments": ["Awesome Pic", "WOOHOOOOO THIS IS GREAT"],
"likes": []
}, {
"url": "6\/image_4.png",
"date_added": "2015-12-02 22:42:59",
"comments": [],
"likes": []
}, {
"url": "2\/image_1.png",
"date_added": "2015-12-01 06:43:48",
"comments": [],
"likes": []
}, {
"url": "2\/image_4.png",
"date_added": "2015-12-01 06:43:48",
"comments": [],
"likes": []
}, {
"url": "2\/image_5.png",
"date_added": "2015-12-01 06:43:48",
"comments": ["EhHHHH"],
"likes": []
}]}
I tried everything but it just fails. Here is what I have so far.
我尝试了一切，但它失败了。这是我到目前为止所拥有的。
if(response["success"] as! Int == 1){
if let images = response["content"] as AnyObject?{
// Does not work if I put NSDictionary? instead of AnyObject
// PRINTS THE OBJECT
print(images)
if let url = images["url"] as String?{
// DOES NOT WORK
print(url)
}
}
}else{
// Print error
let response = response["message"] as! String
print(response)
}

content is an collection, not a single object. So instead of NSDictionary, you should cast it to NSArray and iterate through each item.
content是一个集合，而不是一个对象。因此，您应该将其转换为NSArray并迭代每个项目，而不是NSDictionary。
let isSuccess = response["success"] as! Bool
if(isSuccess)
{
if let dataArr=response["content"] as? NSArray
{
for item in dataArr
{
if let itemDict = item as? NSDictionary
{
let url= itemDict["url"] as! String
//Access other properties also here
}
}
}
}
