词典对象 NSDictionary与NSMutableDictionary
词典的关键字为NSDictionary与NSMutableDictionary。对OC稍有认识的朋友应该从关键字的结构就可以看出这两个的区别。很明显前者为不可变词典，后者为可变词典。 UIApplicationMain(argc, argv, nil, nil); [pool release]; return retVal; } 2.创建可变词典对象 NSMutableDictionary [NSMutableDictionary dictionaryWithCapacity:10] : 创建一个可变词典初始指定它的长度为10. [NSMutableDictionary initWithCapacity:10] :只是初始化一个词典的长度为10。 *dictionary = [NSMutableDictionary dictionaryWithCapacity:10]; //向词典中动态添加数据 [dictionary

OC知识--Foundation框架详尽总结之『字典类』
NSMutableDictionary 1.NSMutableDictionary介绍 NSMutableDictionary是NSDictionary的子类 NSDictionary是不可变的，一旦初始化完毕后 ，它里面的内容就永远是固定的，不能删除里面的元素，也不能再往里面添加元素 NSMutableDictionary是可变的，随时可以往里面添加\更改\删除元素 2. :(id <NSCopying>)aKey; NSMutableDictionary *dict = [NSMutableDictionary dictionary]; [dict setObject :@"Walkers" forKey:@"name"]; NSLog(@"%@", dict); 输出结果： { name = Walkers; } NSMutableDictionary * *dict = [NSMutableDictionary dictionary]; [dict setValuesForKeysWithDictionary: @{@"name":@"Walkers"
