1、从程序内 发送短信

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

短信的内容无法初始化，至少在3.2之前是这样，但是可以通过将要初始化的信息写到拷贝里来弥补。

2、从程序内 发送邮件

-(void) checkSender:(id) sender{

Class mailClass = (NSClassFromString(@"MFMailComposeViewController"));

if (mailClass != nil) {

if ([mailClass canSendMail]){

[self displayComposerSheet];

}else{

[self launchMailAppOnDevice];

}

} else{

[self launchMailAppOnDevice];

}

}

#pragma mark -

#pragma mark Compose Mail

// Displays an email composition interface inside the application. Populates all the Mail fields. 

-(void)displayComposerSheet 

{

MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init];

picker.mailComposeDelegate = self;

[picker setSubject:@"subject"];

// Fill out the email body text

NSString *emailBody = @"email body";

[picker setMessageBody:emailBody isHTML:NO];

[self presentModalViewController:picker animated:YES];

    [picker release];

}

- (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error 

{

[self dismissModalViewControllerAnimated:YES];

}

3、从程序里 打开safari

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://tr4work.blog.163.com/"]];

4、从程序里 打开电话功能

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://1000000"]];

5、制作一个黏贴，拷贝

UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];

pasteboard.string =@"初始化信息";
