如何从用JSONModel编写的NSArray中删除重复数据？

// 导入JSONModel库
#import "JSONModel.h"

// 定义JSONModel子类
@interface MyModel : JSONModel
@property (nonatomic, strong) NSString *name;
@end

@implementation MyModel
@end

// 创建NSArray并填充数据
NSArray *array = @[
    [[MyModel alloc] initWithDictionary:@{@"name": @"John"} error:nil],
    [[MyModel alloc] initWithDictionary:@{@"name": @"Jane"} error:nil],
    [[MyModel alloc] initWithDictionary:@{@"name": @"John"} error:nil],
    [[MyModel alloc] initWithDictionary:@{@"name": @"Alice"} error:nil]
];

// 将NSArray转换为NSSet
NSMutableSet *set = [NSMutableSet set];
for (MyModel *model in array) {
    NSString *jsonString = [model toJSONString];
    [set addObject:jsonString];
}

// 将NSSet转换回NSArray
NSMutableArray *resultArray = [NSMutableArray array];
for (NSString *jsonString in set) {
    MyModel *model = [[MyModel alloc] initWithString:jsonString error:nil];
    [resultArray addObject:model];
}

// 输出结果
for (MyModel *model in resultArray) {
    NSLog(@"%@", model.name);
}
