如何在plist文件中编辑特定的NSDictionary？

Question

我在plist文件中有20个字典。我需要用他们的名字编辑一个特定的词典，但我真的不知道如何做到这一点。 我需要获取值并对SearchCountry Dictionary进行更改。

如何编辑特定字典值？

Answer 1

尝试在属性列表中使用NSPorpertyListSerialization进行复杂迭代。

否则，您可能尝试使用以下代码访问特定字典

NSString*  plistPath = [[NSBundle mainBundle] pathForResource:@"yourPList" 
                                                     ofType:@"plist"];
NSDictionary* plistDict = [NSDictionary dictionaryWithContentsOfFile:plistPath]; 
// plistDict contains all the dictionaries inside it now, you could try to access the particular inside the plistDict

id *searchKey = [plistDict objectForKey:@"SearchCountry"]; 
//OR
NSString* searchKeys = [plistDict valueForKeyPath:@"SearchCountry"];

Answer 2

获取这样的子词典：

NSMutableDictionary *plist = [[NSMutableDictionary alloc] initWithContentsOfFile:plistFilename];
NSMutableDictionary *searchCountry = [plist objectForKey:@"SearchCountry"];

更改其中一个值：

 [searchCountry setValue:@"Cleveland" forKey:@"searchcity"];

像这样保存：

BOOL success = [plist writeToFile:plistFilename atomically:YES];
