1. 新建appViewModel

1.1声明需要的属性

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #1e9421 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #c42275 }
p.p3 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px "PingFang SC"; color: #1e9421 }
p.p4 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
span.s1 { }
span.s2 { font: 18.0px "PingFang SC" }
span.s3 { color: #000000 }
span.s4 { color: #6122ae }
span.s5 { font: 18.0px Menlo }
span.s6 { color: #c42275 }
//NSString一般用copy来修饰

@property(nonatomic,copy)NSString *name;

@property(nonatomic,copy)NSString *icon;

//字典转模型的方法

- (id)initWithDict:(NSDictionary *)dict;

1.2字典转模型

p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000 }
p.p2 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #000000; min-height: 21.0px }
p.p3 { margin: 0.0px 0.0px 0.0px 0.0px; font: 18.0px Menlo; color: #c42275 }
span.s1 { }
span.s2 { color: #c42275 }
span.s3 { color: #6122ae }
span.s4 { color: #3e1e81 }
span.s5 { color: #539aa4 }
span.s6 { color: #c81b13 }
span.s7 { color: #000000 }
- (id)initWithDict:(NSDictionary *)dict{

if(self = [super init]){

self.name = dict[@"name"];

self.icon = dict[@"icon"];

}

return self;
