注册
使用 xib搭建界面 主要有以下代码
- 对手机号的输入显示格式 3-4-4格式的 如157 xxxx xxxx
- 发送验证码按钮的控制 以及倒计时
- 注册按钮的状态控制
与后台约定 点击发送验证码按钮发送请求 需要参数
- 手机号码
返回参数：
- status 状态码
- code 验证码
- JSESSIONID
status 表示手机号码的状态
- 已注册
- 未注册
注册界面
手写对三个输入框进行监听
[self.phoneInput addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
[self.passwordInput addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
[self.verificationCodeInput addTarget:self action:@selector(textFieldDidChange:) forControlEvents:UIControlEventEditingChanged];
输入框相关操作
定义四个标志变量
{
BOOL allOK;
BOOL phoeOK;
BOOL codeOk;
BOOL passwordOk;
}
对三个输入框的长度进行限制
- 手机号码 11位
- 验证码 6 位
- 密码 6~20位
只有三个输入框全部满足要求时
注册按钮才可以交互
#pragma mark Textfiled相关
-(void)textFieldDidChange:(UITextField * )textField{
if (textField == self.phoneInput) {
if (textField.text.length < 13) phoeOK = NO;
if (textField.text.length >= 13) {
_sendVerCode.enabled = YES;
phoeOK = YES;
textField.text = [textField.text substringToIndex:13];
}
if(textField.text.length < 13) _sendVerCode.enabled = NO;
}
if (textField == _verificationCodeInput) {
if(textField.text.length < 6) codeOk = NO;
if(textField.text.length==6) codeOk = YES;
if (textField.text.length >= 6) {
textField.text = [textField.text substringToIndex:6];
}
}
if (textField == _passwordInput) {
if(textField.text.length>=6&&textField.text.length<=20)passwordOk = YES;
else passwordOk = NO;
if (textField.text.length >= 20) {
textField.text = [textField.text substringToIndex:20];
}
}
if(phoeOK&&passwordOk&&codeOk){
_registBtu.enabled = YES;
}else{
_registBtu.enabled = NO;
}
}
手机号码的格式 判断 到发送请求时会截取空白符号
-(BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string{
if (textField==_phoneInput) {
if (range.length == 0){
if (textField.text.length == 3 ||textField.text.length == 8) {
textField.text = [NSString stringWithFormat:@"%@ ",textField.text];
}
}
}
return YES;
}
发送验证码请求
首先对手机号码"洗白操作"
+(NSString *)removeSpace:(NSString *)str{
NSMutableString *strM = [NSMutableString stringWithString:str];
[strM replaceOccurrencesOfString:@" " withString:@"" options:NSLiteralSearch range:NSMakeRange(0, strM.length)];
return [strM copy];
}
接着手机号码的验证 验证手机号码是否符合规定
+ (BOOL) validateMobile:(NSString *)mobile
{
//手机号以13， 15，18开头，八个 \d 数字字符
NSString *phoneRegex = @"^((13[0-9])|(15[^4,\\D])|(18[0,0-9]))\\d{8}$";
NSPredicate *phoneTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@",phoneRegex];
return [phoneTest evaluateWithObject:mobile];
}
发送网络请求 解析状态码
[HBNetRequest Get:[NSString stringWithFormat:@"%@?ulogin=%@",REGISTFRIST,phoneNum] para:nil
complete:^(id data) {
[HBAuxiliary saveCookie];
NSUInteger status = [data[@"status"] integerValue] ;
if(status ==0) [self hadRegist];
if(status ==1) {
[self startCountDown];
_respondCode =data[@"code"];
}
[_hud hide:YES];
} fail:^(NSError *error) {
}];
手机已经注册的话提示Toast
[self.view makeToast:@"您的手机号已注册" duration:2.0 position:CSToastPositionCenter];
未注册的话解析code 开始倒计时
参考
#pragma mark 倒计时相关
-(void)startCountDown {
_countDown = 60;
_sendVerCode.enabled = NO;
_timer = [NSTimer timerWithTimeInterval:1.0 target:self selector:@selector(timerFired:) userInfo:nil repeats:YES]; // 需要加入手动RunLoop，需要注意的是在NSTimer工作期间self是被强引用的
[[NSRunLoop currentRunLoop] addTimer:_timer forMode:NSRunLoopCommonModes]; // 使用NSRunLoopCommonModes才能保证RunLoop切换模式时，NSTimer能正常工作。
}
- (void)stopTimer {
if (_timer) {
[_timer invalidate];
}
}
-(void)timerFired:(NSTimer *)timer {
switch (_countDown) {
case 1:
[_sendVerCode setTitle:@"发送验证码" forState:UIControlStateNormal];
_sendVerCode.enabled = YES;
[self stopTimer];
break;
default:
_countDown -=1;
[_sendVerCode setTitle:[NSString stringWithFormat:@"重发(%d)",_countDown] forState:UIControlStateNormal];
break;
}
}
-(void)dealloc {
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIApplicationDidEnterBackgroundNotification object:nil];
[[NSNotificationCenter defaultCenter]removeObserver:self name:UIApplicationWillEnterForegroundNotification object:nil];
[self stopTimer]; // 如果没有在合适的地方销毁定时器就会内存泄漏啦，delloc也不可能执行。正确的销毁定时器这里可以不用写这个方法了，这里只是提个醒
}
//避免重新回到前台错误
-(void)setupNotification {
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(enterBG) name:UIApplicationDidEnterBackgroundNotification object:nil];
[[NSNotificationCenter defaultCenter]addObserver:self selector:@selector(enterFG) name:UIApplicationWillEnterForegroundNotification object:nil];
}
-(void)enterBG {
_beforeDate = [NSDate date];
}
-(void)enterFG {
NSDate * now = [NSDate date];
int interval = (int)ceil([now timeIntervalSinceDate:_beforeDate]);
//减掉后台那段时间
int val = _countDown - interval;
if(val > 1){
_countDown -= interval;
}else{
_countDown = 1;
}
}
避免当应用到后台时 计时停止，当应用退到后台时 订阅消息 并且 存下时间，当应用互道前台时取出时间 计算差值，接着倒计时。
注册
本地校验验证码 和密码格式正确后发送注册请求 参数
- 验证码
- 密码
返回参数后进行其他操作（注册成功后默认已经登录）会调到主页等或进行其他操作
if([_respondCode isEqualToString:_verificationCodeInput.text]&&
[HBAuxiliary validatePassword:_passwordInput.text]){//验证码正确 && 密码格式正确
[_hud show:YES];
[HBNetRequest Post: REGISTlast para:@{@"code" : _verificationCodeInput.text,
@"upassword" : _passwordInput.text,
}complete:^(id data) {
NSInteger status = [data[@"status"] integerValue];
if (status == 1) {
NSDictionary *userDic = data[@"user"];
HBUserItem *user = [[HBUserItem alloc] initWithDictionary:userDic error:nil];
[HBUserItem saveUser:user];
[HBAuxiliary saveCookie];
[_hud hide:YES];
[self hiddenKeyboardForTap];
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
appDelegate.window.rootViewController = [MainViewController new];
}
} fail:^(NSError *error) {
[_hud hide:YES];
}];
还有在适当的时候加上 键盘隐藏代码
- (void)hiddenKeyboardForTap{
[_phoneInput resignFirstResponder];
[_passwordInput resignFirstResponder];
[_verificationCodeInput resignFirstResponder];
}
