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

if (canSendSMS) {

MFMessageComposeViewController *picker = [[MFMessageComposeViewController
alloc] init];
picker.messageComposeDelegate =
self;
picker.navigationBar.tintColor = [UIColor
blackColor];
picker.body =
@"test";
picker.recipients = [NSArray
arrayWithObject:@"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 = [[MFMessageComposeViewController
alloc] init];
picker.messageComposeDelegate =
self;
UIWebView *web =
nil;
NSMutableString* absUrl = [[NSMutableString
alloc] initWithString:web.request.URL.absoluteString];
[absUrl replaceOccurrencesOfString:@"http://i.aizheke.com"
withString:@"http://m.aizheke.com"
options:NSCaseInsensitiveSearch
range:NSMakeRange(0, [absUrl
length])];
picker.body=[NSString
stringWithFormat:@"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
}
}
