更新swift版本
fileprivate let filePath: String = {
///每个账号对应一个文件
let path = NSTemporaryDirectory() + "\(kUserInfo.userId)-history.hs"
return path
}()
- 加载
func loadHistory() {
if #available(iOS 11.0, *) {
let url = URL(fileURLWithPath: filePath)
guard let data = try? Data(contentsOf: url) else {
return
}
guard let list = try? NSKeyedUnarchiver.unarchiveTopLevelObjectWithData(data) as? [String] else {
DebugLog("加载历史记录失败")
return
}
DebugLog(list)
lists = list
} else {
guard let list = NSKeyedUnarchiver.unarchiveObject(withFile: filePath) as? [String] else {
DebugLog("加载历史记录失败")
return
}
DebugLog(list)
lists = list
}
}
- 保存
fileprivate func saveAction() -> Bool {
if #available(iOS 11.0, *) {
guard let data = try? NSKeyedArchiver.archivedData(withRootObject: lists, requiringSecureCoding: false) else {
return false
}
let url = URL(fileURLWithPath: filePath)
guard ((try? data.write(to: url)) != nil) else { return false }
}
return NSKeyedArchiver.archiveRootObject(lists, toFile: filePath)
}
自定义对象的归档，使用iOS11的API
+archivedDataWithRootObject:requiringSecureCoding:error:
+unarchivedObjectOfClasses:fromData:error:
+unarchivedObjectOfClass:fromData:error:
自定义类Book，遵守NSSecureCoding协议
Book.h
@interface Book : NSObject<NSSecureCoding>
@property (nonatomic, strong) NSString *bookName;
@end
实现supportsSecureCoding、- initWithCoder:、 -encodeWithCoder:方法

+ (BOOL)supportsSecureCoding {
return YES;
}
- (id)initWithCoder:(NSCoder *)coder { ... }
- (void)encodeWithCoder:(NSCoder *)coder { ... }

SERIALIZER_CODER_DECODER宏贴在末尾

1. 单个Book对象的归档
Book *book = [Book new];
book.bookName = @"book";
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:book requiringSecureCoding:NO error:nil];
Book *unarchiverBook = [NSKeyedUnarchiver unarchivedObjectOfClass:[Book class] fromData:data error:nil];
2. Book数组的归档
当修改数组的Book对象时，归档的数据不会受到影响
Book *book1 = [Book new];
book1.bookName = @"book1";
Book *book2 = [Book new];
book2.bookName = @"book2";
NSArray *books = @[book1, book2];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:books requiringSecureCoding:NO error:nil];
//修改book2
Book *nb = books.lastObject;
nb.bookName = @"new bookName 2";
//打印原来的books
for (Book *book in books) {
NSLog(@"1---%@", book.bookName);
}
NSArray *unarchivers = [NSKeyedUnarchiver unarchivedObjectOfClasses:[NSSet setWithArray:@[Book.class, NSArray.class]] fromData:data error:nil];
//打印解档的books
for (Book *book in unarchivers) {
NSLog(@"2---%@", book.bookName);
}
打印结果
1---book1
1---new bookName 2 //数据变动
2---book1
2---book2 //数据未变
3. Book字典的归档
- (void)dictionaryDemo {
Book *book1 = [Book new];
book1.bookName = @"book1";
Book *book2 = [Book new];
book2.bookName = @"book2";
//1. 原始数据
NSDictionary *dic = @{@"a": book1, @"b": book2};
for (Book *book in dic.allValues) {
NSLog(@"1---%@", book.bookName);
}
//2.归档
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:dic requiringSecureCoding:NO error:nil];
//3.修改原始数据
Book *nb = dic.allValues.lastObject;
nb.bookName = @"new bookName";
for (Book *book in dic.allValues) {
NSLog(@"2---%@", book.bookName);
}
//4.解档
NSDictionary *unarchiver = [NSKeyedUnarchiver unarchivedObjectOfClasses:[NSSet setWithArray:@[Book.class, NSDictionary.class]] fromData:data error:nil];
for (Book *book in unarchiver.allValues) {
NSLog(@"3---%@", book.bookName);
}
}
- 打印
1---book1
1---book2
2---book1
2---new bookName
3---book1
3---book2
4. 非自定义对象的归档
NSArray *strings = @[@"book1", @"book2"];
NSData *data = [NSKeyedArchiver archivedDataWithRootObject:strings requiringSecureCoding:NO error:nil];
NSArray *unarchiverStrs = [NSKeyedUnarchiver unarchivedObjectOfClass:[NSArray class] fromData:data error:nil];
for (NSString *str in unarchiverStrs) {
NSLog(@"%@", str);
}
5. 归档宏SERIALIZER_CODER_DECODER
Runtime+CoderDeCoder.h
#import <objc/runtime.h>

6. 给NSObject分类添加归档方法

- 测试
- (void)extStringDemo {
//字符串数组归档
NSMutableArray *strs = [NSMutableArray arrayWithArray:@[@"book1", @"book2"]];
id archive = [strs extArchivierObjectClassType:NSString.class customType:NO];

//修改book

}

}
7. 制作静态库.a
- 创建静态库，名称：
StaticLibrary
image.png
- 将归档的分类文件拖进来(这里将生成的
StaticLibrary.h、StaticLibrary.m删除了)
在build phases的copy files添加.h
image.png
- 切换
debug、release模式
image.png
- 编译
.a
image.png
得到不同架构的.a文件
image.png
- 合并2个
.a得到ArchiveFramework.a
lipo -create 静态库1的路径 静态库2的路径 -output 要生成的静态库路径+静态库名称
lipo -create ../Release-iphoneos/libStaticLibrary.a libStaticLibrary.a -output ArchiveFramework.a
image.png
- 将
.h、.a拖入项目就可以调用了
