这篇文章是自己通过实践获取，在网上查过很多资料，也走了不上的弯路，由于刚开始学子不久，只是把自己遇到的问题贡献给大家
一，创建文件
//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 = [[NSMutableDictionaryalloc
] init];
//设置属性值
[dictplist
setObject:@"张三" forKey:@"name"];
[dictplist
setObject:@"李四"forKey:@"name1"];
[dictplist
setObject:@"王五"forKey:@"name2"];
//写入文件
[dictplist
writeToFile:plistPath atomically:YES];
这个是创建了一个简单的plist文件，创建后的图1为：
下面是创建了一种多键值的plist文件，代码和图如下：
//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 = [[NSMutableDictionaryalloc
] init];
//定义第一个插件的属性
NSMutableDictionary *plugin1 = [[NSMutableDictionaryalloc]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 = [[NSMutableDictionaryalloc]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];
图2：
针对图1进行修改的程序，代码如下：
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,
YES) objectAtIndex:0]stringByAppendingPathComponent:@"test.plist"];
NSMutableDictionary *applist = [[[NSMutableDictionaryalloc]initWithContentsOfFile:path]mutableCopy];
NSString *name = [applist objectForKey:@"name"];
name =
@"山山";
[applist
setObject:name forKey:@"name"];
[applist
writeToFile:path atomically:YES];
执行后如下图：
针对图2进行修改的程序，代码如下：
[dictplist writeToFile:plistPath atomically:YES];
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,
YES)objectAtIndex:0]stringByAppendingPathComponent:@"test.plist"];
//根据路径获取test.plist的全部内容
NSMutableDictionary *infolist= [[[NSMutableDictionaryalloc]initWithContentsOfFile:path]mutableCopy];
//获取初一班的信息
NSMutableDictionary *info = [infolist objectForKey:@"初一班"];
NSString *name1 = [info objectForKey:@"name1"];
name1 =
@"山山";
[info
setValue:name1 forKey:@"name1"];
[infolist
setValue:info forKey:@"初一班"];
[infolist
writeToFile:path atomically:YES];
图如下：
以上两个修改信息的地方，必须要加入红色标记的方法，才能在表里进行增改操作。
以上是个人的学习心得，请大家多多指教。
