如何使用系統(tǒng)自帶的打電話、發(fā)短信、發(fā)郵件、上網(wǎng)？##

使用storyboard畫了下面幾顆按鈕

點(diǎn)擊相應(yīng)的按鈕執(zhí)行對(duì)應(yīng)的操作

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

打電話###

- (IBAction)callButtonClicked:(UIButton *)sender {
    // 電話號(hào)碼
    NSString *phoneNumber=@"13888888888";
    // 直接撥打電話
    //NSString *url=[NSString stringWithFormat:@"tel://%@",phoneNumber];
    // 會(huì)提示用戶是否撥打電話
    NSString *url=[NSString stringWithFormat:@"telprompt://%@",phoneNumber];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}

發(fā)短信###

- (IBAction)messageButtonClicked:(UIButton *)sender {
    NSString *phoneNumber=@"13888888888";
    NSString *url=[NSString stringWithFormat:@"sms://%@",phoneNumber];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}

發(fā)郵件###

- (IBAction)emailButtonClicked:(UIButton *)sender {
    NSString *mailAddress=@"123456789@qq.com";
    NSString *url=[NSString stringWithFormat:@"mailto://%@",mailAddress];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}

上網(wǎng)###

- (IBAction)internetButtonClicked:(UIButton *)sender {
    NSString *url=@"http://www.baidu.com";
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}

@end

說(shuō)明:按照這種方式進(jìn)行操作，點(diǎn)擊按鈕執(zhí)行完相應(yīng)的操作之后不能回到APP界面了。
