Dictionary to model and lazy loading

1. Dictionary Turn model

Create a class that inherits from NSObject, with the property name and dictionary key consistent

can implement dictionary to model

@implementation Tzmessage

+ (Instancetype) messagewithdict (nsdictioary*) dict{

Tzmessage *mode = [[Tzmessage alloc] init];

[Mode setvaluesforkeyswithdictonary:dict];

return mode;

}

2. Lazy Loading

+ (Nsarray *) messages{

if (!_messages) {

NSString *filepath = [[NSBundle mainbundle] pathforresource:@ "messages.plist" oftype:nil];

Nsarray *array = [Nsarray Arraywithcontentsoffile:filepath];

Nsmutablearray *temparray = [Nsmutablearray array];

For (nsdictionary *dict in array) {

Tzmessage *mode = [Tzmessage messagewithdict:dict];

[Temparray Addobject:mode]

}

_messages = Temparray;

}

Retrun _messages;

}
