Question

我是 iPhone开发的新手。我只是创建应用程序，如聊天application.simple我使用JSON解析方法，我通过PHP从服务器调用数据并发回给他们。所以我有一个UIButton我想在这个 UIButton上设置徽章我已经通过一些编码设置徽章：

viewdid加载的时间：* .m 文件 *

self.badgeFive = [[MKNumberBadgeView alloc] initWithFrame:CGRectMake(self.next7.frame.size.width - 22,-20,44,40)];
[self.next7 addSubview:self.badgeFive];

.h 文件中的

：

@property (retain) MKNumberBadgeView* badgeFive;
@property (unsafe_unretained, nonatomic) IBOutlet UIButton *next7;

在上面的代码中，next7是click event.i可以在此按钮上成功添加徽章但是faild移动到下一页。我无法点击此按钮现在。在 next7 事件中，我将此页面称为：

-(IBAction)next7{
    msgfromuserViewController *tenth = [[msgfromuserViewController alloc] initWithNibName:nil bundle:nil];
   [self presentViewController:tenth animated:YES completion:NULL];
}

所以我需要显示徽章，并且点击此按钮并想要转到下一页。同时徽章将显示未读消息的编号。

是否有此类应用程序的示例代码或源代码可以管理点击事件，并显示未读消息的徽章。我很想知道但我不明白我该如何发展？

enter image description here

    UIButton *button =  [UIButton buttonWithType:UIButtonTypeCustom];
            [button setBackgroundImage:[UIImage imageNamed:@"cart_icon.png"] forState:UIControlStateNormal];
            [button addTarget:self action:@selector(Cart_btn:) forControlEvents:UIControlEventTouchUpInside];
            [button.imageView setContentMode:UIViewContentModeScaleToFill];
            [button setFrame:CGRectMake(0, 0, 36, 33)];
            [self.view addSubview:button];



  UILabel *lbl_card_count = [[UILabel alloc]initWithFrame:CGRectMake(23,0, 13, 13)];
                lbl_card_count.textColor = [UIColor whiteColor];
                lbl_card_count.textAlignment = NSTextAlignmentCenter;
                lbl_card_count.text = [NSString stringWithFormat:@"%d",Temp_card_count];
                lbl_card_count.layer.borderWidth = 1;
                lbl_card_count.layer.cornerRadius = 8;
                lbl_card_count.layer.masksToBounds = YES;
                lbl_card_count.layer.borderColor =[[UIColor clearColor] CGColor];
                lbl_card_count.layer.shadowColor = [[UIColor clearColor] CGColor];
                lbl_card_count.layer.shadowOffset = CGSizeMake(0.0, 0.0);
                lbl_card_count.layer.shadowOpacity = 0.0;
                lbl_card_count.backgroundColor = [UIColor colorWithRed:247.0/255.0 green:45.0/255.0 blue:143.0/255.0 alpha:1.0];
                lbl_card_count.font = [UIFont fontWithName:@"ArialMT" size:11];
                [self.view addSubview:lbl_card_count];
                [lbl_card_count release];
