把请求的数据（数组和和单条数据）存放到Model中
#import <Foundation/Foundation.h>
@interface VideoPinglunModel : NSObject
@property (nonatomic , assign)NSInteger commentUserid;
@property (nonatomic , assign)NSInteger commentCtime;
@property (nonatomic , copy)NSString *commentContent;
@property (nonatomic , copy)NSString *commentAuthor;
- (instancetype)initWithDictionary:(NSDictionary *)dic;
+ (NSMutableArray *)modelSformDics:(NSArray *)arr;
@end
- (void)setValue:(id)value forUndefinedKey:(NSString *)key
{
// if ([key isEqualToString:@"id"]) {
// self.idM = value;
// }
}
- (id)valueForUndefinedKey:(NSString *)key
{
return nil;
}
- (instancetype)initWithDictionary:(NSDictionary *)dic
{
self = [super init];
if (self) {
[self setValuesForKeysWithDictionary:dic];
}
return self;
}
+ (NSMutableArray *)modelSformDics:(NSArray *)arr
{
NSMutableArray *modelArr = [NSMutableArray array];
for (NSDictionary *dic in arr) {
VideoPinglunModel *model = [[self alloc] initWithDictionary:dic];
[modelArr addObject:model];
}
return modelArr;
}
使用方法；
//从解析的数组中查出需要的数据，存放到类的字典里面
NSMutableDictionary *dic = [responseObject objectForKey:@"data"];
playingModel *model = [[playingModel alloc] initWithDictionary:dic];
2、Model存放到中字典中（数据存到Model中）
#import <Foundation/Foundation.h>
@interface playingModel : NSObject
@property (nonatomic , copy)NSString *t; //标题吧 。。。
@property (nonatomic , copy)NSString *tag;
@property (nonatomic , copy)NSString *desc;
@property (nonatomic , copy)NSString *picpath; //图片地址
@property (nonatomic , copy)NSString *bigpicpath;
@property (nonatomic , assign)NSInteger vtime;
@property (nonatomic , copy)NSString *f; //视频播放地址
- (instancetype)initWithDictionary:(NSDictionary *)dic;
+ (instancetype)modelSformDics:(NSDictionary *)dic;
@end
#import "playingModel.h"
@implementation playingModel
- (void)setValue:(id)value forUndefinedKey:(NSString *)key
{
}
- (id)valueForUndefinedKey:(NSString *)key
{
return nil;
}
- (instancetype)initWithDictionary:(NSDictionary *)dic
{
self = [super init];
if (self) {
[self setValuesForKeysWithDictionary:dic];
}
return self;
}
+ (instancetype)modelSformDics:(NSDictionary *)dic;
{
playingModel *model = [[self alloc] initWithDictionary:dic];
return model;
}
@end
