SFVerificationCodeView
SFVerificationCodeView,实现iOS本地生成随机验证码, 从服务器读取并生成验证码
验证码其实主要用来防止机器人恶意注册与登陆，基本用于web网页端
XIB拖拽方式
//设置验证码生成模式 服务器端生成验证码
self.codeView.mode = SFVerificationCodeModeServer;
[self.codeView willChangeVerificationCode:^(SFVerificationCodeMode mode) {
NSLog(@"请求服务器生成code");
[self getData:nil completion:^(NSDictionary *dict) {
self.codeView.code = [dict objectForKey:@"code"];
}];
}];
[self.codeView didChangeVerificationCode:^(NSString *code) {
NSLog(@"self.codeView code:%@",code);
}];
//开始生成code
[self.codeView generateVerificationCode];
//模拟异步从后台接口请求验证码
- (void)getData:(id)data completion:(void (^)(NSDictionary *dict))completion{
//网络请求
NSString *code = [NSString stringWithFormat:@"server%zd",arc4random() % 100];
NSDictionary *dict = @{@"code":code};
completion(dict);
}
代码方式
//设置验证码生成模式 本地生成验证码
view.mode = SFVerificationCodeModeLocal;
[view willChangeVerificationCode:^(SFVerificationCodeMode mode) {
NSLog(@"本地随机生成code");
}];
[view didChangeVerificationCode:^(NSString *code) {
NSLog(@"view code:%@",code);
}];
//开始生成code
[view generateVerificationCode];
