用字典給Model賦值

用字典給model賦值

此篇教程講述通過runtime擴充套件nsobject，可以直接用字典給model賦值，這是相當有用的技術呢。

原始碼：nsobject+properties.h 與 nsobject+properties.m

//

//  nsobject+properties.h
////  created by youxianming on 14-9-4.
//#import @inte***ce nsobject (properties)
- (void)setdatadictionary:(nsdictionary*)datadictionary;
- (nsdictionary *)datadictionary;
@end

//

//  nsobject+properties.m
////  created by youxianming on 14-9-4.
//#import "nsobject+properties.h"
#import @implementation nsobject (properties)
#pragma public - 公開方法
- (void)setdatadictionary:(nsdictionary*)datadictionary
- (nsdictionary *)datadictionary
#pragma private - 私有方法
// 通過屬性名字拼湊setter方法
- (sel)getsetterselwithattibutename:(nsstring*)attributename
// 通過字典設定屬性值
- (void)setattributes:(nsdictionary*)datadic obj:(id)obj
else
// 執行setter方法
[obj performselectoronmainthread:sel
withobject:value
waituntildone:[nsthread ismainthread]];}}
}// 獲取乙個類的屬性名字列表
- (nsarray*)propertynames:(class)class
free(properties);
return propertynames;
}// 根據屬性陣列獲取該屬性的值
- (nsdictionary*)propertiesandvaluesdictionary:(id)obj properties:(nsarray *)properties
propertiesvaluesdic[property] = valueobj;}}
return propertiesvaluesdic;
}@end

model.h 與 model.m

//

//  model.h
//  runtime
////  created by youxianming on 14-9-5.
//#import @inte***ce model : nsobject
@property (nonatomic, strong) nsstring      *name;
@property (nonatomic, strong) nsnumber      *age;
@property (nonatomic, strong) nsdictionary  *addressinfo;
@property (nonatomic, strong) nsarray       *events;
@end

//

//  model.m
//  runtime
////  created by youxianming on 14-9-5.
//#import "model.h"
@implementation model
@end

//

//  runtime
////  created by youxianming on 14-9-5.
//#import "nsobject+properties.h"
#import "model.h"
,                             @"events"      : @[@"one", @"two", @"three"]};
// 列印出屬性值
nslog(@"%@", model.datadictionary);
return yes;
}@end

age = 26;

events =     (

one,

two,

three

);

name = youxianming;

}以下是兩段核心**(符合單一職能)：

不能用字串給字元陣列賦值

c和指標 pointers on c 8.1.11 乙個字串，如 hello 一般為字串常量，可以用它對字元指標賦值，或初始化，相當於把這個字串常量的首位址賦給這個指標，如 char p hello 或者 char p p hello 但是，當用 hello 給字元陣列作初始化時，hello 並非乙...

iOS JSON字典轉模型model

ios開發中，經常會用到字典轉模型，咱們平常常用的是mjexstend框架，該框架功能完善，但是在咱們用的時候基本上只是在資料解析的時候會用到json字典轉模型，僅此乙個功能，你們龐大的一套框架，是不是有些浪費啦，所以咱們自己寫乙個小的分類，運用一點點知識點就可以搞定，下面直接上 該分類有三個功能 ...
