APP拨号与发短信功能

在很多APP里面有拨号功能,比如在美团外卖上面可以点击商家电话后给商家打电话,今天要做的就是这个功能.这个功能其实非常非常简单,但需要真机运行才可以实现,虚拟机不行.看看代码你们就知道多简单了.

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    self.view.backgroundColor = [UIColor whiteColor];
    UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
    button.frame = CGRectMake(100, 100, 175, 50);
    [button setTitle:@"打电话" forState:UIControlStateNormal];
    button.backgroundColor = [UIColor cyanColor];
    [button addTarget:self action:@selector(call) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button];
    
    UIButton *button1 = [UIButton buttonWithType:UIButtonTypeSystem];
    button1.frame = CGRectMake(100, 200, 175, 50);
    [button1 setTitle:@"发短信" forState:UIControlStateNormal];
    button1.backgroundColor = [UIColor cyanColor];
    [button1 addTarget:self action:@selector(sendMessage) forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:button1];
}
-(void)call
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];
}
-(void)sendMessage
{
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://10010"]];
}
- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

@end

是不是非常简单?
当你按下打电话button时,手机就会给10086打电话,当你按下发短信button时,手机就会跳转到短信编辑界面,而发送人就是10010.
希望这个能对你们有用.祝大家开心😄
