iOS:从字典中的.plist读取数据

Question

我想从 .app 目录中的 plist 中检索数据。我不知道如何获取子词典数据。例如，我想获取 MemoriesDictionary/Memory1/Event1/EventName 值。

我可以将 MemoryCount 值获取到 iMemCount 中:

int iMemCount;

//Do file searching/getting for plist

NSString *plistDirectory = [[NSBundle mainBundle] pathForResource:@"memoryDetails" ofType:@"plist"];
NSLog(@"array: %@",plistDirectory);

NSFileManager *fileManager = [NSFileManager defaultManager];

if ([fileManager fileExistsAtPath: plistDirectory]) //4
{
    NSLog(@"exists");
    NSMutableDictionary *savedStock = [[NSMutableDictionary alloc] initWithContentsOfFile: plistDirectory];

    iMemCount = [[savedStock objectForKey:@"MemoryCount"] intValue];


} else {
    NSLog(@"Does Not Exist");
    iMemCount = 0;
}

Answer 1

NSString *string = savedStock[@"MemoriesDictionary"][@"Memory1"][@"Event1"][@"EventName"];

编辑

您还可以重写:

int iMemCount;
iMemCount = [[savedStock objectForKey:@"MemoryCount"] intValue];

作为

NSInteger iMemCount;
iMemCount = [savedStock[@"MemoryCount"] integerValue];

您确实应该考虑 iOS 代码在 64 位处理器上运行的可能性，并使用适当的平台安全类型(NSInteger、CGFloat、CFIndex等)
