這篇文章是自己通過實踐獲取，在網上查過很多資料，也走了不上的彎路，由於剛開始學子不久，只是把自己遇到的問題貢獻給大家
一，創建文件
//獲取路徑對象
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//獲取完整路徑
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *plistPath = [documentsDirectory stringByAppendingPathComponent:@"test.plist"];
NSMutableDictionary *dictplist = [[NSMutableDictionary alloc ] init];
//設置屬性值
[dictplist setObject:@"張三" forKey:@"name"];
[dictplist setObject:@"李四" forKey:@"name1"];
[dictplist setObject:@"王五" forKey:@"name2"];
//寫入文件
[dictplist writeToFile:plistPath atomically:YES];
這個是創建了一個簡單的plist文件，創建後的圖1爲：
下面是創建了一種多鍵值的plist文件，代碼和圖如下：
//獲取路徑對象
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
//獲取完整路徑
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *plistPath = [documentsDirectory stringByAppendingPathComponent:@"test.plist"];
NSMutableDictionary *dictplist = [[NSMutableDictionary alloc ] init];
//定義第一個插件的屬性
NSMutableDictionary *plugin1 = [[NSMutableDictionary alloc]init];
[plugin1 setObject:@"張三" forKey:@"name1"];
[plugin1 setObject:@"李四" forKey:@"name2"];
//定義第二個插件的屬性
NSMutableDictionary *plugin2 = [[NSMutableDictionary alloc]init];
[plugin2 setObject:@"王五" forKey:@"name1"];
[plugin2 setObject:@"趙斌" forKey:@"name2"];
//設置屬性值
[dictplist setObject:plugin1 forKey:@"初一班"];
[dictplist setObject:plugin2 forKey:@"初二班"];
//寫入文件
[dictplist writeToFile:plistPath atomically:YES];
圖2：
針對圖1進行修改的程序，代碼如下：
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]stringByAppendingPathComponent:@"test.plist"];
NSMutableDictionary *applist = [[[NSMutableDictionary alloc]initWithContentsOfFile:path]mutableCopy];
NSString *name = [applist objectForKey:@"name"];
name = @"山山";
[applist setObject:name forKey:@"name"];
[applist writeToFile:path atomically:YES];
執行後如下圖：
針對圖2進行修改的程序，代碼如下：
[dictplist writeToFile:plistPath atomically:YES];
NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)objectAtIndex:0]stringByAppendingPathComponent:@"test.plist"];
//根據路徑獲取test.plist的全部內容
NSMutableDictionary *infolist= [[[NSMutableDictionary alloc]initWithContentsOfFile:path]mutableCopy];
//獲取初一班的信息
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];
圖如下：
以上兩個修改信息的地方，必須要加入紅色標記的方法，才能在表裏進行增改操作。
以上是個人的學習心得，請大家多多指教。
