我正在创建一个带有状态列表的UITableView，一旦您在其中一个单元格中选择一个状态，它就会切换到下一个视图，该视图将包含与该状态对应的城市列表。到目前为止，这是我的一系列城市：
- (id)initWithStyle:(UITableViewStyle)style
{
self = [super initWithStyle:style];
if (self) {
NSMutableArray *mainArray = [[NSMutableArray alloc] init];
self.section1 = @[@"Alabama",@"Alaska",@"Arizona",@"Arkansas",@"California",@"Colorado",@"Connecticut",@"Delaware"];
self.section2 = @[@"Florida",@"Georgia",@"Hawaii",@"Idaho",@"Illinois",@"Indiana",@"Iowa",@"Kansas",@"Kentucky",@"Louisiana"];
self.section3 = @[@"Maine",@"Maryland",@"Massachusetts",@"Michigan",@"Minnesota",@"Mississippi",@"Misouri",@"Montana"];
self.section4 = @[@"Nevada",@"Nebraska",@"New Hampshire",@"New Jersey",@"New Mexico",@"New York",@"North Carolina",@"North Dakota",@"Ohio",@"Ohio",@"Oklahoma",@"Oregon"];
self.section5 = @[@"Pennsylvania",@"Rhode Island",@"South Carolina",@"South Dakota",@"Tennessee",@"Texas",@"Utah"];
self.section6 = @[@"Vermont",@"Virginia",@"Washington",@"West Virginia",@"Wisconsin",@"Wyoming"];
}
return self;
}
那么我是否必须创建一个单独的城市数组，然后将这两个数组合并为一个字典，然后相应地对列表进行排序？此外，我希望一旦选择单元格来存储并根据所选的城市或州传递字符串。
像这样：SanFrancisco.California

答案 0 :(得分：0)
我建议为每个州创建一个类，其中包含属性的NSString和包含所有相应城市的数组。然后，将状态对象存储在字典中，状态名称为键。
