1.普通json转model方式
解析下面的一段json
{ "id":"324566", "name":"周瑜", "nick_name":"公瑾", "girl_friend":"小乔" }
1.1 OC-Model解析
建立OC类
@interface OCPerson : NSObject
@property (strong, nonatomic) NSString *personID;
@property (strong, nonatomic) NSString *name;
@property (strong, nonatomic) NSString *nickName;
@property (strong, nonatomic) NSString *girlFriend;
@end
@implementation OCPerson
+ (NSDictionary *)mj_replacedKeyFromPropertyName{
return @{@"personID" : @"id",
@"nickName": @"nick_name",
@"girlFriend": @"girl_friend"};
}
@end
使用的时候
OCPerson *person = [OCPerson mj_objectWithKeyValues:[self getPersonJson]];
打断点如下图所示
1.2 Swift-Model解析
建立Swift Model
class SwiftPerson: NSObject {
var personID: String?
var name: String?
var nickName: String?
var girlFriend: String?
override init() {
super.init()
}
override static func mj_replacedKeyFromPropertyName() -> [AnyHashable : Any]{
return ["personID": "id",
"nickName": "nick_name",
"girlFriend": "girl_friend"]
}
}
在oc里使用
SwiftPerson *person = [SwiftPerson mj_objectWithKeyValues:[self getPersonJson]];
NSLog(@"person=%@",person.girlFriend);
在Swift里使用
let path = Bundle.main.path(forResource: "person.json", ofType: nil)
do {
guard let data = NSData.init(contentsOfFile: path!) else{
return
}
guard let dict = try JSONSerialization.jsonObject(with: data as Data, options: JSONSerialization.ReadingOptions.mutableLeaves) as? Dictionary<AnyHashable, Any> else{
return
}
NSLog("dict=%@", dict)
let person = SwiftPerson.mj_object(withKeyValues:dict)
NSLog("person.girlFriend=%@", person?.girlFriend ?? "null")
} catch {
}
2.解析嵌套json Array
需要解析如下的json
{
"start_date":"2017-12-12",
"end_date":"2018-02-02",
"items":[
{
"id":"324566",
"name":"周瑜",
"nick_name":"公瑾",
"girl_friend":"小乔"
},
{
"id":"432145",
"name":"曹操",
"nick_name":"孟德",
"girl_friend":"抢人家小乔"
}
]
}
2.1 OC Model解析
2.1.1 建立OC People类
@interface OCPeople : NSObject
@property (strong, nonatomic) NSString *startDate;
@property (strong, nonatomic) NSString *endDate;
@property (strong, nonatomic) NSArray *list;
@end
2.1.2 配置key对应关系和array对应关系类
@implementation OCPeople
+ (NSDictionary *)mj_replacedKeyFromPropertyName{
return @{@"startDate" : @"start_date",
@"endDate": @"end_date",
@"list": @"items"};
}
+ (NSDictionary *)mj_objectClassInArray{
return @{
@"list" : @"OCPerson"
};
}
解析效果,打断点如下所示
2.2 Swift Model解析
2.2.1 建立Swift People类
class SwiftPeople: NSObject {
var startDate: String?
var endDate: String?
var list: [SwiftPerson]?
override init() {
super.init()
}
}
2.2.2 配置key关系和Array类关系
override static func mj_replacedKeyFromPropertyName() -> [AnyHashable : Any]{
return ["startDate": "start_date",
"endDate": "end_date",
"list": "items"]
}
override func mj_keyValuesDidFinishConvertingToObject() {
if self.list != nil {
let items = SwiftPerson.mj_objectArray(withKeyValuesArray: self.list)
if items != nil {
self.list = items! as NSArray as? [SwiftPerson]
}
}
}
在这里不能像OC那样重写mj_objectClassInArray
方法,而是需要重写mj_keyValuesDidFinishConvertingToObject
方法(具体原因可以看源码,下回分解)
在OC里调用解析效果如下:
在Swift里调用解析效果如下:
