如何使用系统自带的打电话、发短信、发邮件、上网？##
使用storyboard画了下面几颗按钮

点击相应的按钮执行对应的操作
@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.
}
打电话###
- (IBAction)callButtonClicked:(UIButton *)sender {
// 电话号码
NSString *phoneNumber=@"13888888888";
// 直接拨打电话
//NSString *url=[NSString stringWithFormat:@"tel://%@",phoneNumber];
// 会提示用户是否拨打电话
NSString *url=[NSString stringWithFormat:@"telprompt://%@",phoneNumber];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}
发短信###
- (IBAction)messageButtonClicked:(UIButton *)sender {
NSString *phoneNumber=@"13888888888";
NSString *url=[NSString stringWithFormat:@"sms://%@",phoneNumber];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}
发邮件###
- (IBAction)emailButtonClicked:(UIButton *)sender {
NSString *mailAddress=@"123456789@qq.com";
NSString *url=[NSString stringWithFormat:@"mailto://%@",mailAddress];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}
上网###
- (IBAction)internetButtonClicked:(UIButton *)sender {
NSString *url=@"http://www.baidu.com";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];
}
@end
说明:按照这种方式进行操作，点击按钮执行完相应的操作之后不能回到APP界面了。
