如何将我的nsarray中的不同对象添加到nsstring

NSArray *array = @[ @"Apple", @123, [NSDate date], @{@"key": @"value"} ];
NSMutableString *resultString = [NSMutableString string];

for (id object in array) {
    if ([object isKindOfClass:[NSString class]]) {
        [resultString appendString:object];
    } else if ([object isKindOfClass:[NSNumber class]]) {
        [resultString appendString:[object stringValue]];
    } else {
        [resultString appendString:[object description]];
    }
    
    // 添加分隔符（可根据需要自定义）
    [resultString appendString:@", "];
}

// 移除最后一个分隔符
if ([resultString length] > 0) {
    [resultString deleteCharactersInRange:NSMakeRange([resultString length]-2, 2)];
}

NSString *finalString = [resultString copy];
NSLog(@"%@", finalString);
