3、plist文件存储的实现步骤
3.1手动创建plist文件
Snip20161107_5.png
*** 说明：plist文件（属性列表）是一种XML格式的文件，拓展名为plist；如果对象是NSString、NSDictionary、NSArray、NSData、NSNumber等类型，就可以使用writeToFile:atomically:方法直接将对象写到属性列表文件中***
3.2给plist文件添加内容作为tableView的数据源数组
Snip20161107_9.png
3.3从plist文件中读取数据的核心代码
-(NSArray *)groups{
if (_groups ==nil) {
// 1.获取文件路径
NSString *filePath = [[NSBundle mainBundle] pathForResource:self.plistName ofType:@"plist"];
_groups = [NSArray arrayWithContentsOfFile:filePath];
}
return _groups;
}
选中单元格cell跳转到下一个控制器
// 选中cell
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSDictionary *group = self.groups[indexPath.section];
NSArray *items = group[@"items"];
// 获取每行cell的信息
NSDictionary *item = items[indexPath.row];
NSString *vcString = item[@"targetVC"];
if (vcString && vcString.length >0 ) {
// 根据字符串创建和字符串名字相同的类
Class cla = NSClassFromString(vcString);
UIViewController *targetVC = [[cla alloc]init];
if ([targetVC isKindOfClass:[CLSettingViewController class]]) {
CLSettingViewController *settingVC = (CLSettingViewController * ) targetVC;
settingVC.plistName = item[@"plistName"];
}
// 设置控制器的标题
targetVC.title = item[@"title"];
[self.navigationController pushViewController:targetVC animated:YES];
}
}
3.4使用偏好设置NSUserDefaults保存开关的状态
// 重写setter方法
- (void)setItem:(NSDictionary *)item{
_item = item ;
// 设置cell的title
self.textLabel.text = item[@"title"];
//设置cell的图片
self.imageView.image = [UIImage imageNamed:item[@"icon"]];
NSString * imageView = item[@"accessoryView"];//@"UIImageView"
//根据字符串转化类
Class cla = NSClassFromString(imageView);// UIImageView 类
//根据类创建类的对象
id obj = [[cla alloc] init];//创建类的对象
if([obj isKindOfClass:[UIImageView class]])
{
UIImageView * imageView = (UIImageView *)obj;
imageView.image = [UIImage imageNamed:@"arrow_right"];
//图片框和图片大小一样
[imageView sizeToFit];
}else if ([obj isKindOfClass:[UISwitch class] ]){
UISwitch *mySwitch = (UISwitch *)obj;
// 从偏好设置获取值
NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
mySwitch.on = [userDefaults boolForKey:self.item[@"switchKey"]];
// 给开关添加事件
[mySwitch addTarget:self action:@selector(valueChanged:) forControlEvents:UIControlEventValueChanged];
}
//添加辅助view
self.accessoryView = obj;
}
// 开关的点击事件
-(void)valueChanged:(UISwitch *)sender{
//存储到偏好设置
NSUserDefaults * userDefaults = [NSUserDefaults standardUserDefaults];
//设置值
[userDefaults setBool:sender.isOn forKey:self.item[@"switchKey"]];
[userDefaults synchronize];
}
3.5代码创建plist文件
#import "CLContact.h"
@implementation CLContact
// 编码 使用kvc进行编码
- (void)encodeWithCoder:(NSCoder *)aCoder{
[aCoder encodeObject:self.name forKey:@"name"];
[aCoder encodeObject:self.phone forKey:@"phone"];
}
// 解码 从字符串获取对象
- ( instancetype)initWithCoder:(NSCoder *)aDecoder{
if (self == [super init]) {
self.name = [aDecoder decodeObjectForKey:@"name" ];
self.phone = [aDecoder decodeObjectForKey:@"phone"];
}
return self;
}
@end
// ViewController.m
// 代码创建plist存储数据

@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
[self test];
// 沙盒document文件路径
NSString *docPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES) lastObject];
// document中存储的plist文件的全路径
NSString *filePath = [docPath stringByAppendingPathComponent:@"contact.plist"];
CLContact *contact = [NSKeyedUnarchiver unarchiveObjectWithFile:filePath];
NSLog(@"%@----%@",contact.name,contact.phone);
}
-(void)test{
CLContact *contact = [[CLContact alloc] init];
contact.name = @"liudehua";
contact.phone = @"1234";
NSString *docDir= [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
NSString *filePath = [docDir stringByAppendingPathComponent:@"contact.plist"];
[NSKeyedArchiver archiveRootObject:contact toFile:filePath];
NSLog(@"%@",filePath);
}
@end
