SNYKeychain

简单使用 Keychain 保存数据 使用方法

//存

    NSString * str = @"598922307";
    [SNYKeychain setObject:str forKey:@"strKey"];

    NSArray * arr = @[@"1",@"2",@"3"];
    [SNYKeychain setObject:arr forKey:@"arrKey"];

    NSDictionary * dict = @{@"k1":@"v1",@"k2":@"v2"};
    [SNYKeychain setObject:dict forKey:@"dictKey"];

    People * p = [[People alloc] init];
    p.name = @"sny";
    [SNYKeychain setObject:p forKey:@"pKey"];

//取

    NSString * str1 = [SNYKeychain objecForKey:@"strKey"];
    NSLog(@"str1:%@",str1);

    NSArray * arr1 = [SNYKeychain objecForKey:@"arrKey"];
    NSLog(@"arr1:%@",arr1);

    NSArray * dict1 = [SNYKeychain objecForKey:@"dictKey"];
    NSLog(@"dict1:%@",dict1);

    People * p1 = [SNYKeychain objecForKey:@"pKey"];
    NSLog(@"p1:%@",p1);

模拟器下需要打开 Keychain sharing
