Demo地址

1.手势密码

API

/** 是否已经创建过手势密码 */
+ (BOOL)haveGesturePassword;

/** 获取手势密码 */
+ (NSString *)getGesturesPassword;

/** 删除手势密码 */
+ (void)deleteGesturesPassword;

/**
 展示 手势密码视图
 @param type 类型 (YWUnlockViewCreate,//创建手势密码 YWUnlockViewUnlock//解锁手势密码)
 */
+ (void)showUnlockViewWithType:(YWUnlockViewType)type callBack:(CallBackBlock)callBack;

使用方法

    //创建手势密码
    [YWUnlockView showUnlockViewWithType:YWUnlockViewCreate callBack:^(BOOL result) {
        NSLog(@"-->%@",@(result));
    }];

    //验证手势密码
    [YWUnlockView showUnlockViewWithType:YWUnlockViewUnlock callBack:^(BOOL result) {
        NSLog(@"-->%@",@(result));
    }];

2.指纹验证

关于指纹验证,之前一篇文章已经写过,这里简单封装了下

使用方法

[YWFingerprintVerification fingerprintVerificationCallBack:^(NSError *error) {
        if(!error){
            NSLog(@"指纹验证通过");
        }else{
            NSLog(@"指纹验证失败->%@", @(error.code));
        }
    }];

代码如下

YWFingerprintVerification.h

#import <Foundation/Foundation.h>
#import <LocalAuthentication/LocalAuthentication.h>

/** error.code */
/** 
 typedef NS_ENUM(NSInteger, LAError)
 {
 //用户验证没有通过，比如提供了错误的手指的指纹
 LAErrorAuthenticationFailed = kLAErrorAuthenticationFailed,
 
 // 用户取消了Touch ID验证
 LAErrorUserCancel           = kLAErrorUserCancel,
 
 //用户不想进行Touch ID验证，想进行输入密码操作
 LAErrorUserFallback         = kLAErrorUserFallback,
 
 // 系统终止了验证
 LAErrorSystemCancel         = kLAErrorSystemCancel,
 
 // 用户没有在设备Settings中设定密码
 LAErrorPasscodeNotSet       = kLAErrorPasscodeNotSet,
 
 // 设备不支持Touch ID
 LAErrorTouchIDNotAvailable  = kLAErrorTouchIDNotAvailable,
 
 // 设备没有进行Touch ID 指纹注册
 LAErrorTouchIDNotEnrolled   = kLAErrorTouchIDNotEnrolled,
 } NS_ENUM_AVAILABLE(10_10, 8_0);
 */

@interface YWFingerprintVerification : NSObject

/**
 指纹验证
 @param callBack 验证结果
 */
+ (void)fingerprintVerificationCallBack:(void(^)(NSError *error))callBack;

@end

YWFingerprintVerification.m

#import "YWFingerprintVerification.h"

@implementation YWFingerprintVerification

+ (void)fingerprintVerificationCallBack:(void(^)(NSError *error))callBack;{
    //本地认证上下文联系对象
    LAContext * context = [[LAContext alloc] init];
    NSError * error = nil;
    //验证是否具有指纹认证功能，不建议使用版本判断方式实现
    BOOL canEvaluatePolicy = [context canEvaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics error:&error];
    if (error) {
        NSLog(@"%@", error.localizedDescription);
        !callBack?:callBack(error);
    }
    if (canEvaluatePolicy) {
        NSLog(@"有指纹认证功能");
        //匹配指纹
        [context evaluatePolicy:LAPolicyDeviceOwnerAuthenticationWithBiometrics localizedReason:@"验证指纹已确认您的身份" reply:^(BOOL success, NSError *error) {
            if (success) {
                NSLog(@"指纹验证成功");
                !callBack?:callBack(nil);
            } else {
                NSLog(@"验证失败");
                NSLog(@"%@",error.localizedDescription);
                !callBack?:callBack(error);
            }
        }];
    } else {
        NSLog(@"无指纹认证功能");
    }
}

@end
