ios 调用系统发短信以及打电话功能

先介绍一种最简单的方法：

调用打电话功能

[[UIApplicationsharedApplication] openURL:[NSURL URLWithString:@"tel://10086"]];

调用发短信功能

[[UIApplication sharedApplication]openURL:[NSURL URLWithString:@"sms://10000"]];

上面的发短信的功能是调用系统的界面，下面是实现一种点击按键就直接发送短信，相当于后台发送，能不能上软件商店，还不能确定。相对建议来说，尽量使用第一种。

首先导入MFMessageComposeViewControllerDelegate这个代理，实现里面的方法

-(void)messageComposeViewController:(MFMessageComposeViewController *)controllerdidFinishWithResult:(MessageComposeResult)result {

//Notifies users about errors associated with the interface

switch (result) {

case MessageComposeResultCancelled:

if (DEBUG)NSLog(@"Result: canceled");

break;

case MessageComposeResultSent:

if (DEBUG)NSLog(@"Result: Sent");

break;

case MessageComposeResultFailed:

if (DEBUG)NSLog(@"Result: Failed");

break;

default:

break;

}

[self dismissModalViewControllerAnimated:YES];

}

群发短信：

- (IBAction)sendSMS {

BOOL canSendSMS = [MFMessageComposeViewControllercanSendText];

NSLog(@"can send SMS [%d]",canSendSMS);

if (canSendSMS) {

MFMessageComposeViewController *picker = [[MFMessageComposeViewControlleralloc] init];

picker.messageComposeDelegate =self;

picker.navigationBar.tintColor = [UIColorblackColor];

picker.body = @"test";

picker.recipients = [NSArrayarrayWithObject:@"10086"];

[self presentModalViewController:picker animated:YES];

[picker release];

}

}

给一个人发短信：
从网页上获得内容

-(void)displaySMSComposerSheet

{

MFMessageComposeViewController *picker = [[MFMessageComposeViewControlleralloc] init];

picker.messageComposeDelegate =self;

UIWebView *web = nil;

NSMutableString* absUrl = [[NSMutableStringalloc] initWithString:web.request.URL.absoluteString];

[absUrl replaceOccurrencesOfString:@"http://i.aizheke.com"withString:@"http://m.aizheke.com"options:NSCaseInsensitiveSearchrange:NSMakeRange(0, [absUrllength])];

picker.body=[NSStringstringWithFormat:@"我在爱折客上看到：%@可能对你有用，推荐给你！link：%@",[webstringByEvaluatingJavaScriptFromString:@"document.title"],absUrl];

[absUrl release];

[self presentModalViewController:picker animated:YES];

[picker release];

}

事件绑定发送短信

-(IBAction)showSMSPicker:(id)sender {

Class messageClass = (NSClassFromString(@"MFMessageComposeViewController"));

if (messageClass != nil) {

if ([messageClass canSendText]) {

[self displaySMSComposerSheet];

}

else {

//设备没有短信功能

}

}

else {

// iOS版本过低,iOS4.0以上才支持程序内发送短信

}

}
