復(fù)雜對(duì)象存入數(shù)組歸檔的方法如下:
- (void)complexObjectArchiver
{
Person *personA = [[Person alloc] init];
personA.name = @"張三";
personA.age = 20;
personA.sex = @"男";
Person *personB = [[Person alloc] init];
personB.name = @"李四";
personB.age = 15;
personB.sex = @"女";
Person *personC = [[Person alloc] init];
personC.name = @"王五";
personC.age = 30;
personC.sex = @"男";
NSString *paths = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES) firstObject];
NSLog(@"Caches: %@", paths);
NSMutableArray *personsArr = [NSMutableArray arrayWithObjects:personA, personB, personC, nil];
NSString *personsArrPath = [paths stringByAppendingString:@"/personsArr.plist"];
[NSKeyedArchiver archiveRootObject:personsArr toFile:personsArrPath];
NSLog(@"personsArrPath: %@", personsArrPath);
NSArray *newPersonsArr = [NSKeyedUnarchiver unarchiveObjectWithFile:personsArrPath];
NSLog(@"反歸檔: %@", newPersonsArr);
for (Person *tempPerson in newPersonsArr) {
NSLog(@"name: %@, age: %ld, sex: %@", tempPerson.name, tempPerson.age, tempPerson.sex);
}
}
注意: model對(duì)象 首先要實(shí)現(xiàn) 歸檔和解檔方法
例子:
model為:
@property (nonatomic,copy) NSString *id;
@property (nonatomic,copy) NSString *name;
//歸檔
- (void)encodeWithCoder:(NSCoder *)aCoder{
[aCoder encodeObject:self.id forKey:@"id"];
[aCoder encodeObject:self.name forKey:@"name"];
}
//解檔
- (instancetype)initWithCoder:(NSCoder *)aDecoder{
if (self = [super init]){
self.id = [aDecoder decodeObjectForKey:@"id"];
self.name = [aDecoder decodeObjectForKey:@"name"];
}
return self;
}
