Send SMS in iOS 7 it not work - sms

Question

- (IBAction)button_number1:(id)sender {
MFMessageComposeViewController *textComposer = [[MFMessageComposeViewController alloc] init];
[textComposer setMessageComposeDelegate:self];
if ([MFMessageComposeViewController canSendText]) {
[textComposer setRecipients:#[string_numberphone]];
[textComposer setBody:#"ABC"];
[self presentViewController:textComposer animated:YES completion:NULL];
} else {
NSLog(#"Can't Open Text");
}
}
}
when I click a button_number1, it does not work, and no arlet Error.
But when clicking the button below, it works normally on iOS 7 but I can not assign the message content.
Please guide me how to assign the message content to this button_number2.
- (IBAction)button_number2:(id)sender {
NSString *message = [[NSString alloc] initWithFormat:#"sms:%#",string_numberphone];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:message ]];
}
Thank so much!

in .h header file.....
#import <MessageUI/MessageUI.h>
#interface MainViewController : UIViewController <MFMessageComposeViewControllerDelegate>{
- (IBAction)sendsms:(id)sender;
}
in .m implementation file.....
- (IBAction)showEmail:(id)sender{
if (phoneNumber!=NULL) {
UIDevice *device = [UIDevice currentDevice];
if ([[device model] isEqualToString:#"iPhone"] ) {
NSString *phNo = [phoneNumber stringByReplacingOccurrencesOfString:#" " withString:#""];
NSURL *phoneUrl = [NSURL URLWithString:[NSString stringWithFormat:#"telprompt:%#",phNo]];
if ([[UIApplication sharedApplication] canOpenURL:phoneUrl]) {
[[UIApplication sharedApplication] openURL:phoneUrl];
} else
{
UIAlertView *calert = [[UIAlertView alloc]initWithTitle:#"Alert" message:#"Call facility is not available!!!" delegate:nil cancelButtonTitle:#"ok" otherButtonTitles:nil, nil];
[calert show];
[calert release];
}
} else {
UIAlertView *warning =[[UIAlertView alloc] initWithTitle:#"Alert" message:#"Your device doesn't support this feature." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[warning show];
[warning release];
}
}
else {
UIAlertView *warning =[[UIAlertView alloc] initWithTitle:#"Alert" message:#"Phone No is not Available." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[warning show];
[warning release];
}
