系统盘datePicker、调整Nav后退按钮位置调整,电话短信邮件分享

一、设置软键盘为时间选择器

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
self.indexPath = indexPath;
//获取当前点击的cell
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];

//为了点击cell的时候能弹出键盘
//生成文本框，并且让文本框成为第一响应者
UITextField *txt = [UITextField new];
[cell addSubview:txt];

//设置键盘的工具栏
CZKeyboard *tool = [CZKeyboard keyboardTool];
tool.delegate = self;
txt.inputAccessoryView = tool;


//弹出datePicker
UIDatePicker *datePicker = [[UIDatePicker alloc] init];
self.datePicker = datePicker;
datePicker.datePickerMode = UIDatePickerModeTime;
datePicker.backgroundColor = [UIColor lightGrayColor];

//把弹出键盘改成datePicker
txt.inputView = datePicker;

//让文本框成为第一响应者，此处之前 应该先设置inputView
[txt becomeFirstResponder];
}

二、自定义后退按钮位置调整

//如果tableView启用分组的话。第一组之前会有空白。把空白去掉
 self.tableView.tableHeaderView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 0, -1)];
    ```
 
 

    //1  自定义后退按钮
UIBarButtonItem *backItem = [[UIBarButtonItem alloc] initWithImage:[[UIImage imageNamed:@"NavBack"] originalImage] style:UIBarButtonItemStylePlain target:self action:@selector(backClick)];

// 后退按钮距离图片距离左边边距
UIBarButtonItem *fixedItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFixedSpace target:nil action:nil];
fixedItem.width = -10;

self.navigationItem.leftBarButtonItems = @[fixedItem,backItem];



//自定义后退按钮后，手势返回上一级控制器的功能恢复
self.navigationController.interactivePopGestureRecognizer.delegate = nil;
```

三、NSInterger格式问题

%ld
%d
%zd 根据当前系统判断返回类型 64位 32位

四、电话分享、短信分享、邮件分享

  __weak typeof(self) weakSelf = self;
    
    CZItem *item1 = [CZItemArrow itemWithTitle:@"电话分享" icon:nil option:^{
        //通话完成会回到当前应用， 以前的时候不会回到当前应用
//        NSURL *url = [NSURL URLWithString:@"tel://54188"];
//        [[UIApplication sharedApplication] openURL:url];
        
        
        //打电话之前会有提示  回到当前应用   私有的api
//        NSURL *url = [NSURL URLWithString:@"telprompt://54188"];
//        [[UIApplication sharedApplication] openURL:url];
        
        NSURL *url = [NSURL URLWithString:@"tel://54188"];
        NSURLRequest *request = [NSURLRequest requestWithURL:url];
        [weakSelf.webView loadRequest:request];
        
    }];
    
    CZItem *item2 = [CZItemArrow itemWithTitle:@"短信分享" icon:nil option:^{
        
        //发完短信之后。会到短信界面
//        NSURL *url = [NSURL URLWithString:@"sms://54188"];
//        [[UIApplication sharedApplication] openURL:url];
        
        
        //判断设备是否能发送信息
        if (![MFMessageComposeViewController canSendText]) {
            return;
        }
        
        MFMessageComposeViewController *vc = [MFMessageComposeViewController new];
        //收件人列表
        vc.recipients = @[@"10000",@"10086"];
        vc.body = @"推荐一个nb的游戏 http://www.nlcoder.com/test";
        vc.subject = @"biaoti";
        //设置代理
        vc.messageComposeDelegate = weakSelf;
        
        [weakSelf presentViewController:vc animated:YES completion:nil];
        
    }];
    
    CZItem *item3 = [CZItemArrow itemWithTitle:@"邮件分享" icon:nil option:^{
        
        //判断是否能发送邮件
        if (![MFMailComposeViewController canSendMail]) {
            return;
        }
        
        MFMailComposeViewController *vc = [MFMailComposeViewController new];
        
        vc.mailComposeDelegate = weakSelf;
        //设置收件人
        [vc setToRecipients:@[@"[email protected]",@"[email protected]"]];
        //密送
//        [vc setBccRecipients:<#(NSArray *)#>]
        //抄送
//        [vc setCcRecipients:<#(NSArray *)#>]
        
        [vc setSubject:@"收福利了"];
        [vc setMessageBody:@"送美女" isHTML:NO];
        
        //
        UIImage *img = [UIImage imageNamed:@"aa"];
        NSData *data = UIImagePNGRepresentation(img);
        
        [vc addAttachmentData:data mimeType:@"image/png" fileName:@"cls.png"];
        
        
        
        [weakSelf presentViewController:vc animated:YES completion:nil];
        
    }];
    
    //controller(self) --> self.groups -->  group  -->  item   --> option  --> self
    
    CZGroup *group = [CZGroup groupWithItems:@[item1,item2,item3]];
    self.groups = @[group];
