我有一个具有以下键值的 NSditonary 对象
密钥:1.infoKey、2.infoKey、3.infoKey、4.infoKey、5.infoKey、6.infoKey、7.infoKey、8.infoKey、9.infoKey、10.infoKey、11.infoKey
请注意,它们没有排序,可以按任何顺序排列,即 3.infoKey、7.infoKey、2.infoKey 等
我要做的是对键值进行排序,即 1,2,3,4,5,6,7,8,9,10,11 .... 这是我迄今为止使用的代码,但每次我做了一个排序,它按我不想要的顺序排序(见下文)
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *stringsPlistPath = [[paths objectAtIndex:0] stringByAppendingPathComponent:@"talkBtns.plist"];
NSMutableDictionary *dictionary2 = [[NSMutableDictionary alloc] initWithContentsOfFile:stringsPlistPath];
NSArray *myKeys = [dictionary2 allKeys];
//This didn't give the right results
//sortedKeys = [myKeys sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];
//This didn't give the right results either
NSSortDescriptor* sortDescriptor = [NSSortDescriptor sortDescriptorWithKey:nil ascending:YES selector:@selector(localizedCompare:)];
sortedKeys = [myKeys sortedArrayUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]];
// ***********
// GET KEY VALUES TO
// LOOP OVER
// ***********
/* */
for (int i = 0; i < [sortedKeys count]; i++)
{
NSLog(@"[sortedKeys objectAtIndex:i]: %@", [sortedKeys objectAtIndex:i]);
}
//output I get
[sortedKeys objectAtIndex:i]: 1.infoKey
[sortedKeys objectAtIndex:i]: 10.infoKey
[sortedKeys objectAtIndex:i]: 11.infoKey
[sortedKeys objectAtIndex:i]: 2.infoKey
[sortedKeys objectAtIndex:i]: 3.infoKey
[sortedKeys objectAtIndex:i]: 4.infoKey
[sortedKeys objectAtIndex:i]: 5.infoKey
[sortedKeys objectAtIndex:i]: 6.infoKey
[sortedKeys objectAtIndex:i]: 7.infoKey
[sortedKeys objectAtIndex:i]: 8.infoKey
[sortedKeys objectAtIndex:i]: 9.infoKey
我尝试了两种方法,它们都给出了相同的结果。我搜索了堆栈溢出和谷歌的每个地方,但找不到适合我的需求。
有什么建议么?
