动态识别设备的IOS版本

Question

可能重复:
检查iPhone iOS版本

我正在构建一个具有SMS编写器的应用程序(在3.0中不可用).如何动态查找底层设备的操作系统版本并使SMS选项可用,如果不能禁用该功能.

Answer 1

这是一段代码,它将为您提供有关设备的所有信息

NSLog(@"uniqueIdentifier: %@", [[UIDevice currentDevice] uniqueIdentifier]);
    NSLog(@"name: %@", [[UIDevice currentDevice] name]);
    NSLog(@"systemName: %@", [[UIDevice currentDevice] systemName]);
    NSLog(@"systemVersion: %@", [[UIDevice currentDevice] systemVersion]);
    NSLog(@"model: %@", [[UIDevice currentDevice] model]);
    NSLog(@"localizedModel: %@", [[UIDevice currentDevice] localizedModel]);

你可以在这里找到版本号.

但我建议你去检查手机是否支持邮件编辑,短信或不喜欢

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

if (messageClass != nil) {          
    // Check whether the current device is configured for sending SMS messages
    if ([messageClass canSendText])
    {
        MFMessageComposeViewController *msgpicker = [[MFMessageComposeViewController alloc] init];
        msgpicker.messageComposeDelegate = self;
        msgpicker.recipients = [NSArray arrayWithObject:[self.productInfoArray valueForKey:@"Phone"]]; // your recipient number or self for testing
        msgpicker.body = @"test from OS4";
        NSLog(@"chat view array  %@",[self.productInfoArray valueForKey:@"Phone"]);
        [self presentModalViewController:msgpicker animated:YES];
        [msgpicker release];
        NSLog(@"SMS fired");


    }
    else {      NSLog(@"chat view array  %@",[self.productInfoArray valueForKey:@"Phone"]);
        NSLog(@"Device not configured to send SMS.") ;
        UIAlertView *alert= [[UIAlertView alloc]initWithTitle:@"Status" message:@"Device not configured to send SMS." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:@"cancel",nil];
        [alert show];
        [alert release];

    }
}

这有助于解决您的问题.快乐的编码干杯................
