很多时候我们需要利用我门自己的app进行一些打电话、发短信等的操作,那么如何利用代码实现呢,下面就介绍一些简单的方法来实现这些操作。
一、打电话:
<1>最简单、最直接的方法----直接跳转到拨号界面
NSURL *url = [NSURL URLWithString:@"tel://10010"];
[[UIApplication sharedApplication] openURL:url];
缺点:打完电话后,不能跳回到原来的应用,而是直接停留在通话记录界面。
<2>拨号之前会弹框询问用户是否拨号,拨完后能自动回到原来的应用。
NSURL *url = [NSURL URLWithString:@"telprompt://10010"];
[[UIApplication sharedApplication] openURL:url];
if (_webView == nil) {
_webView = [[UIWebView alloc] initWithFrame:CGRectZero];
}
[_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"tel://10010"]]];
需要注意的是:这个webView千万不要添加到界面上来,不然会挡住其他界面
二、发短信
NSURL *url = [NSURL URLWithString:@"sms://10010"];
[[UIApplication sharedApplication] openURL:url];
<2>如果想指定短信内容,那就得使用MessageUI框架
#import <MessageUI/MessageUI.h>
MFMessageComposeViewController *vc = [[MFMessageComposeViewController alloc] init];
// 设置短信内容
vc.body = @"吃饭了没?";
// 设置收件人列表
vc.recipients = @[@"10010", @"02010010"];
// 设置代理
vc.messageComposeDelegate = self;
// 显示控制器
[self presentViewController:vc animated:YES completion:nil];
- (void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{
// 关闭短信界面
[controller dismissViewControllerAnimated:YES completion:nil];
if (result == MessageComposeResultCancelled) {
NSLog(@"取消发送");
} else if (result == MessageComposeResultSent) {
NSLog(@"已经发出");
} else {
NSLog(@"发送失败");
}
}
三、发邮件
NSURL *url = [NSURL URLWithString:@"mailto://10010@qq.com"];
[[UIApplication sharedApplication] openURL:url];
<2>跟发短信的第2种方法差不多,只不过控制器类名叫做:MFMailComposeViewController
- (void)mailComposeController:(MFMailComposeViewController *)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError *)error
{
// 关闭邮件界面
[controller dismissViewControllerAnimated:YES completion:nil];
if (result == MFMailComposeResultCancelled) {
NSLog(@"取消发送");
} else if (result == MFMailComposeResultSent) {
NSLog(@"已经发出");
} else {
NSLog(@"发送失败");
}
NSURL *url = [NSURL URLWithString:@”http://www.baidu.com"];
[[UIApplication sharedApplication] openURL:url];
NSURL *url = [NSURL URLWithString:@"mj://ios.itcast.cn"];
[[UIApplication sharedApplication] openURL:url]
