我可以从plist中读取钥匙吗？

Question

如果我知道值可以读取密钥,我是否可以从plist中读取没有其值的密钥？

Answer 1

阅读.plist:

NSString *path = [[NSBundle mainBundle] pathForResource:@"myPlist" ofType:@"plist"];    
NSMutableDictionary *myDictionary = [[NSMutableDictionary alloc] initWithContentsOfFile:path];

获取所有键和所有值:

NSArray* allmyKeys = [myDictionary  allKeys];
NSArray* allmyValues= [myDictionary  allValues];

获取值对象的所有键:

NSArray* allmyKeys = [myDictionary  allKeysForObject:myValueObject];
