在APP开发中,点击获取验证码的倒计时按钮 是在注册、修改密码、绑定手机号等场景中使用!在项目中,多次使用这个按钮,则自定义一个简单的获取短信验证码倒计时功能方便使用, 大大提高开发效率。
一、主要思路
1、自定义验证码按钮:ZLVerifyCodeButton
2、自定义文本输入框:ZLTextField
3、正则表达式:手机号及密码校验方法
4、修改密码界面里调用这个短信验证码,调取后台接口,获取短信验证码处理相关其他逻辑.
二、程序实现
Step1. 首先自定义按钮:ZLVerifyCodeButton
只需要调用方法即可,可以在自定义里按照自己需求去更改按钮的UI。
@interface ZLVerifyCodeButton : UIButton// 由于有些时间需求不同,特意露出方法,倒计时时间次数- (void)timeFailBeginFrom:(NSInteger)timeCount;@end
自定义按钮:
- (void)setup {[self setTitle:@" 获取验证码 " forState:UIControlStateNormal];self.titleLabel.font = [UIFont systemFontOfSize:10];self.backgroundColor = [UIColor whiteColor];self.layer.cornerRadius = 3.0;self.clipsToBounds = YES;[self setTitleColor:[UIColor redColor] forState:UIControlStateNormal];self.layer.borderColor = [UIColor redColor].CGColor;self.layer.borderWidth = 1.0;}
倒计时方法:
- (void)timeFailBeginFrom:(NSInteger)timeCount {self.count = timeCount;self.enabled = NO;// 加1个计时器self.timer = [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerFired) userInfo:nil repeats:YES];}
计时器方法:
- (void)timerFired {if (self.count != 1) {self.count -= 1;self.enabled = NO;[self setTitle:[NSString stringWithFormat:@"剩余%ld秒", self.count] forState:UIControlStateNormal];// [self setTitle:[NSString stringWithFormat:@"剩余%ld秒", self.count] forState:UIControlStateDisabled];} else {self.enabled = YES;[self setTitle:@"获取验证码" forState:UIControlStateNormal];// self.count = 60;// 停掉定时器[self.timer invalidate];self.timer = nil;}}
Step2. 自定义文本输入框:ZLTextField
- (void)setupUI {// 输入框self.borderStyle = UITextBorderStyleNone;[self setAutocapitalizationType:UITextAutocapitalizationTypeNone];self.backgroundColor = [UIColor whiteColor]; // ZLColor(0, 0, 0);self.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;self.returnKeyType = UIReturnKeyNext;self.font = [UIFont systemFontOfSize:15];self.textColor = ZLColor(113, 111, 118);// 设置光标颜色self.tintColor = ZLColor(113, 111, 118);// 设置UITextField的占位文字颜色self.placeholder = @"设置了占位文字内容以后, 才能设置占位文字的颜色";[self setValue: ZLColor(113, 111, 118) forKeyPath:@"_placeholderLabel.textColor"];// 添加背景图片// self.background = [UIImage imageNamed:@"u58"];// 左间隔self.leftView = [[UIView alloc] init];self.leftView.width = 15;self.leftViewMode = UITextFieldViewModeAlways;// clearButtonself.clearButtonMode = UITextFieldViewModeWhileEditing;CGFloat marginX = 15;// 间隔线UIView *line = [[UIView alloc] init];line.frame = CGRectMake(marginX, self.height - 0.7, UI_View_Width - marginX * 2, 1);line.backgroundColor = ZLColor(249, 249, 249);[self addSubview:line];}
Step3. 正则表达式:手机号及密码校验方法
- (BOOL)match:(NSString *)pattern {// 1.创建正则表达式NSRegularExpression *regex = [[NSRegularExpression alloc] initWithPattern:pattern options:0 error:nil];// 2.测试字符串NSArray *results = [regex matchesInString:self options:0 range:NSMakeRange(0, self.length)];return results.count > 0;}
Step4. 修改密码界面里调用这个短信验证码, 调取后台接口,获取短信验证码处理相关其他逻辑
在你所需要的控制器里调用这个短信验证码按钮即可:
4.1)初始化创建设置相关按钮属性
// 获取验证码按钮@property (nonatomic, weak) ZLVerifyCodeButton *codeBtn;
// 获取验证码按钮ZLVerifyCodeButton *codeBtn = [ZLVerifyCodeButton buttonWithType:UIButtonTypeCustom];codeBtn.frame = CGRectMake(codeField.width - codeBtnW - marginX, 10, codeBtnW, 30);[codeBtn addTarget:self action:@selector(codeBtnVerification) forControlEvents:UIControlEventTouchUpInside];[self.codeField addSubview:codeBtn];self.codeBtn = codeBtn;
4.2)调取后台接口,获取短信验证码处理相关其他逻辑
// 获取验证码点击事件- (void)codeBtnVerification {NSLog(@"验证码:%@", self.mobileField.text);[self.codeBtn timeFailBeginFrom:60]; // 倒计时60s// 调用短信验证码接口// 用户输入的验证码数字传给server,判断请求结果作不同的逻辑处理,根据自己家的产品大大需求来即可....// if (请求成功且匹配成功验证码数字){// [self.codeBtn timeFailBeginFrom:60]; // 倒计时60s// } else {// [self.codeBtn timeFailBeginFrom:1]; // 处理请求成功但是匹配不成功的情况,并不需要执行倒计时功能// }}
4.3)调取后台修改密码接口,处理相关逻辑
// 调用修改密码接口- (void)sureBtnPress {if (![self.mobileField.text isPhoneNumber]) {[self setupAlertMessage:@"新手机号码输入不正确"];} else if (![self.codeField.text isEqualToString:self.codeStr]) {[self setupAlertMessage:@"验证码输入不正确"];} else if(![self.newpswField.text isPSW]) {[self setupAlertMessage:@"新密码不符合要求"];} else if ([self.mobileField.text isPhoneNumber] && [self.codeField.text isEqualToString:self.codeStr] && [self.newpswField.text isPSW]) {// 调用修改密码接口[self changePswForServer];}}// 弹框提示错误信息- (void)setupAlertMessage:(NSString *)message {UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"提示" message:message preferredStyle:UIAlertControllerStyleAlert];UIAlertAction *okAction = [UIAlertAction actionWithTitle:@"确定" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {}];[alert addAction:okAction];[self presentViewController:alert animated:YES completion:nil];}

1、压缩文件截图
2、项目文件截图
3、运行时的效果图
四、其他补充
界面性问题可以根据自己项目需求调整即可, 具体可参考代码, 项目能够直接运行!
