iOS_常用的小功能

• 打电话

NSString *telNumberStr = @"020-12345678";// 方式一：在iOS10.1版本不会弹框提示，直接拨打电话。NSString *telString = [[NSString alloc] initWithFormat:@"tel:%@",telNumberStr];// 方式二：会弹框提示。NSString *telString = [[NSString alloc] initWithFormat:@"telprompt://%@",telNumberStr];[[UIApplication sharedApplication] openURL:[NSURL URLWithString:telString]];

• 发短信方式一：

NSString *url = @"sms://10086";[[UIApplication sharedApplication] openURL:[NSURL URLWithString:url]];

• 发短信方式二：

1、导入框架：#import <MessageUI/MessageUI.h>2、遵循协议：<MFMessageComposeViewControllerDelegate>3、代码调用实现：MFMessageComposeViewController *msgVC =[[MFMessageComposeViewController alloc] init];// 设置短信内容msgVC.body = @"一起玩耍吧";// 设置收件人列表msgVC.recipients = @[@"10086", @"10010"];// 设置代理msgVC.messageComposeDelegate = self;// 显示控制器(self指代ViewController)[self presentViewController:msgVC animated:YES completion:nil];4、代理回调#pragma mark - MFMessageComposeViewControllerDelegate// 短信界面关闭后回调，会自动回到应用的页面- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result{    // 关闭短信页面    [controller dismissViewControllerAnimated:YES completion:nil];    // 返回短信结果    if (result == MessageComposeResultCancelled) {        NSLog(@"点击右上角、取消按钮");    }    if (result == MessageComposeResultSent) {        NSLog(@"短信发送");    }    if (result == MessageComposeResultFailed) {        NSLog(@"发送失败");    }}
