【深入浅出ios开发】数据存储-----XML属性列表（plist）归档

①存储数据：

1.获得home路径：

NSString *home = NSHomeDirectory();

2.通过home路径获得Documents/xxx.plist路径

3.往相应的路径写数据

- (IBAction)save:(id)sender {
    NSString *home = NSHomeDirectory();
    NSLog(@"%@",home);
    
    NSString *strDocument = [home stringByAppendingPathComponent:@"Documents/xml.plist"];
    
    NSArray *array = @[@"A",@"B",@"C"];
    [array writeToFile:strDocument atomically:YES];
}

1.获得相应的plist文件的路径

2.直接通过类相应的方法调用读取数据

- (IBAction)read:(id)sender {
    NSString *home = NSHomeDirectory();
    NSLog(@"%@",home);
    
    NSString *strDocument = [home stringByAppendingPathComponent:@"Documents/xml.plist"];
    NSMutableArray *array = [[NSMutableArray alloc]initWithContentsOfFile:strDocument];
    
    NSLog(@"%@",array);
    
}
