如何按字母顺序对NSMutable数组中的自定义对象字段进行排序？

我有一个自定义对象，如：

I have a custom object like:

#import <Foundation/Foundation.h>

@interface Store : NSObject{
    NSString *name;
    NSString *address;
}

@property (nonatomic, retain) NSString *name;
@property (nonatomic, retain) NSString *address;

@end

我有一个包含商店的NSMutableArray（storeArray）数组对象：

I have an array of NSMutableArray (storeArray) containing Store objects:

store1 = [[Store alloc] init];
store1.name = @"Walmart";    
store1.address = @"walmart address here..";

store2 = [[Store alloc] init];
store2.name = @"Target";
store2.address = @"Target address here..";

store3 = [[Store alloc] init];
store3.name = @"Apple Store";
store3.address = @"Apple store address here..";

//add stores to array
storeArray = [[NSMutableArray alloc] init];
[storeArray addObject:store1];
[storeArray addObject:store2];
[storeArray addObject:store3];

我的问题是如何按商店名称对数组进行排序？我知道我可以使用这一行按字母顺序对数组进行排序：

My question is how can I sort the array by the store name? I know I can sort an array alphabetically by using this line:

[nameOfArray sortedArrayUsingSelector:@selector(caseInsensitiveCompare:)];

如何将此应用于Store类的商店名称？

How can I apply this to the store name of my Store class?
