iOS_常用的小功能

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]];

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

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");
}
}
