ios开发之短信验证

这里使用的SMS_SDK.framework(Mob官网去下载) 来做的短信验证, 操作非常简单, 自己去注册账号拿到appkey 然后就是需要导入一些库文件 需要导入的库有Security.framework Foundation.framework, UIKit.framework, CoreGraphics.framework, libicucore.dylib, libz.lib, AddressBook.framework, AddressBookUI.framework, MessageUI.framework 和 SMS_SDK.framework

//首先来确定一下手机号是否正确以及设置短信的限制时间
if ([_field.text length] == 11) {
        
        [SMS_SDK getVerifyCodeByPhoneNumber:_field.text AndZone:@"86" result:^(enum SMS_GetVerifyCodeResponseState state) {
            if (1 == state) {
                self.times = 15;
                self.timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(buttonActionShow) userInfo:nil repeats:YES];
                [NSTimer scheduledTimerWithTimeInterval:15 target:self selector:@selector(xianzhi:) userInfo:nil repeats:NO];

            } else {
                NSLog(@"filed");
            }
        }];
    } else {
        UIAlertView *aler = [[UIAlertView alloc] initWithTitle:nil message:@"输入电话号码有误" delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定", nil];
        [aler show];
    }

　　

// 验证是否正确
[SMS_SDK commitVerifyCode:self.phone.text result:^(enum SMS_ResponseState state) {
        if (state == 1) {
            UIAlertView *aler = [[UIAlertView alloc] initWithTitle:nil message:@"验证成功" delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定", nil];
            [aler show];
            
        } else {
            UIAlertView *aler = [[UIAlertView alloc] initWithTitle:nil message:@"输入验证码有误" delegate:self cancelButtonTitle:nil otherButtonTitles:@"确定", nil];
            [aler show];
        }
    }];

　　

// xianzhi的方法 - - 这里写拼音了
- (void)xianzhi:(id)sender
{
    [_button setEnabled:YES];
    [_timer invalidate];
    _timer = nil;
    [_button setAlpha:1];
    [_button setTitle:@"重新获取" forState:UIControlStateNormal];
    
}

　　

// 定时器倒数
self.times--;
    self.button.enabled = NO;
    [self.button setTitle:[NSString stringWithFormat:@"%ld秒",self.times] forState:UIControlStateNormal];
