iOS的plist文件如何修改

一、plist文件最外边是字典类型。

*取：

直接用一个字典初始化路径取到即可。如：

#define DOCDIR [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]

NSString * docDir = DOCDIR;

NSString * path = [docDir stringByAppendingPathComponent:@"talkData.plist"];

self.totalDataDict = [NSMutableDictionary dictionaryWithContentsOfFile:path];

*存：

直接修改你的字典最后将字典再存到path路径下覆盖即可。

[self.totalDataDict writeToFile:path atomically:YES];

    //获取路径对象

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);  

    //获取完整路径

    NSString *documentsDirectory = [paths objectAtIndex:0];

    NSString *plistPath = [documentsDirectory stringByAppendingPathComponent:@"test.plist"];

    NSMutableDictionary *dictplist = [[NSMutableDictionary alloc ] init];

    //定义第一个插件的属性

    NSMutableDictionary *plugin1 = [[NSMutableDictionary alloc]init];

    [plugin1 setObject:@"张三" forKey:@"name1"];

    [plugin1 setObject:@"李四" forKey:@"name2"];

    //定义第二个插件的属性

    NSMutableDictionary *plugin2 = [[NSMutableDictionary alloc]init];

    [plugin2 setObject:@"王五" forKey:@"name1"];

    [plugin2 setObject:@"赵斌" forKey:@"name2"];

    //设置属性值

    [dictplist setObject:plugin1 forKey:@"初一班"];

    [dictplist setObject:plugin2 forKey:@"初二班"];

    //写入文件

    [dictplist writeToFile:plistPath atomically:YES];
