调用系统应用

应用间跳转

应用A 跳转至应用B，对B应用设置如示：

• 首先需要注册 URL Schemes

identifier 可选 URL Schemes 必填

• 接受跳转时发过来的URL

//下面方法专门处理从第三方跳转过来的
//9.0以上使用的方法
-(BOOL)application:(UIApplication *)app openURL:(NSURL *)url options:(NSDictionary<NSString *,id> *)options{

  //url 为跳转时的URL
   url.scheme  协议 a123://
   url.host  域名    abc
   url.absoluteString  完整的url字符串  a123://abc

    return YES;
}
//适配低版本
-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(nullable NSString *)sourceApplication annotation:(id)annotation {
    return YES;
}
//2.0出现过，现在多不用
-(BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url{
    return YES;
}

应用跳转事件

//Button的点击效果
- (IBAction)goAction:(UIButtion*)sender{
    //格式为   URL Schemes://（要传递的值）
    NSURL *url = [NSURL URLWithString:@"a123://abc"];
    [[UIApplication sharedApplication] openURL:url];
}
//微信
- (IBAction)weixinAction:(UIButton *)sender {
    
   NSURL *url = [NSURL URLWithString:@"weixin://"];   
    [[UIApplication sharedApplication] openURL:url];
}
//新浪微博
- (IBAction)weiboAction:(UIButton *)sender {
    
    NSURL *url = [NSURL URLWithString:@"weibo://"];
    [[UIApplication sharedApplication] openURL:url];
}

系统应用

- (IBAction)systemAction:(UIButton *)sender {
    
   //调用自带mail

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://admin@hzlzh.com"]];

   //调用电话phone
不提示直接拨号并打出，且无法回到应用
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://8008808888"]];

    //这种调用就会弹出提示框
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"telprompt://8008808888"]];


   //调用SMS，这种不通指定短信内容，不能自动回到原应用
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://8008808888"]];

    //调用safari
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.baidu.com"]];

}
//强制横屏
- (UIInterfaceOrientationMask)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskLandscapeLeft | UIInterfaceOrientationMaskLandscapeRight;
}

关于拨打电话

-(void)onCall:(NSString*)phoneNumber
{
   
    //判断是否是iPhone手机
    if ([UtilFun isIphoneAboutHardWare]) {
        //只实现拨打功能，防止遮挡frame设置为0
        UIWebView *callWebview =[[UIWebView alloc] initWithFrame:CGRectZero];
        NSURL *telURL =[NSURL URLWithString:[NSString stringWithFormat:@"tel:%@",number]];
        [callWebview loadRequest:[NSURLRequest requestWithURL:telURL]];
        [self.view addSubview:callWebview];
    }else {
        NSString*str = [NSString stringWithFormat:@"您的设备没有打电话功能，电话号码:%@",phoneNumber];
    }
}

关于发短信

1.导入框架并实现协议
MessageUI.framework
#import <MessageUI/MessageUI.h>
@interface ViewController ()
 
2.编辑短信内容,群发对象,设置代理并弹出短信界面
   //要做安全判断，否则提示用户不能发信息
  if( [MFMessageComposeViewController canSendText] )

     MFMessageComposeViewController *messageVC = [[MFMessageComposeViewController alloc] init];
     //编辑内容
      messageVC.body = @"你好,我是亲爱的大倩倩";
     //可以群发
      messageVC.recipients = @[@"000000",@"111111",@"222222"];
      messageVC.messageComposeDelegate = self;
     [self presentViewController:messageVC animated:YES completion:nil];
}
 
3.实现代理:短信发完后的回调,在此方法中设置返回原应用程序
参数1: 短信控制器
参数2:短信发送结果
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
    [controller dismissViewControllerAnimated:YES completion:nil];
 
    NSString *messageResult;
    if (result == MessageComposeResultCancelled)
        messageResult = @"短信取消发送";
    else if(result == MessageComposeResultSent)
        messageResult = @"短信已发送";
    else
        messageResult = @"短信发送失败!";
 
    UIAlertController *alertController = [UIAlertController alertControllerWithTitle:messageResult message:nil preferredStyle:UIAlertControllerStyleAlert];
    UIAlertAction *myAction = [UIAlertAction actionWithTitle:@"我知道了" style:UIAlertActionStyleCancel handler:nil];
    [alertController addAction:myAction];
    [self presentViewController:alertController animated:YES completion:nil];
 
}
