85 | or contributory patent infringement, then any patent licenses
86 | granted to You under this License for that Work shall terminate
87 | as of the date such litigation is filed.
88 |
89 | 4. Redistribution. You may reproduce and distribute copies of the
90 | Work or Derivative Works thereof in any medium, with or without
91 | modifications, and in Source or Object form, provided that You

93 |
94 | (a) You must give any other recipients of the Work or
95 | Derivative Works a copy of this License; and
96 |
97 | (b) You must cause any modified files to carry prominent notices
98 | stating that You changed the files; and

104 | the Derivative Works; and
105 |
106 | (d) If the Work includes a "NOTICE" text file as part of its
107 | distribution, then any Derivative Works that You distribute must

113 | documentation, if provided along with the Derivative Works; or,
114 | within a display generated by the Derivative Works, if and
115 | wherever such third-party notices normally appear. The contents
116 | of the NOTICE file are for informational purposes only and
117 | do not modify the License. You may add Your own attribution
118 | notices within Derivative Works that You distribute, alongside
119 | or as an addendum to the NOTICE text from the Work, provided
120 | that such additional attribution notices cannot be construed
121 | as modifying the License.
122 |
123 | You may add Your own copyright statement to Your modifications and

137 |
138 | 6. Trademarks. This License does not grant permission to use the trade
139 | names, trademarks, service marks, or product names of the Licensor,

156 | negligent acts) or agreed to in writing, shall any Contributor be
157 | liable to You for damages, including any direct, indirect, special,
158 | incidental, or consequential damages of any character arising as a

160 | Work (including but not limited to damages for loss of goodwill,
161 | work stoppage, computer failure or malfunction, or any and all
162 | other commercial damages or losses), even if such Contributor
163 | has been advised of the possibility of such damages.
164 |
165 | 9. Accepting Warranty or Additional Liability. While redistributing
166 | the Work or Derivative Works thereof, You may choose to offer,
167 | and charge a fee for, acceptance of support, warranty, indemnity,
168 | or other liability obligations and/or rights consistent with this
169 | License. However, in accepting such obligations, You may act only
170 | on Your own behalf and on Your sole responsibility, not on behalf
171 | of any other Contributor, and only if You agree to indemnify,
172 | defend, and hold each Contributor harmless for any liability
173 | incurred by, or claims asserted against, such Contributor by reason
174 | of your accepting any such warranty or additional liability.

44 | ## SGQRCode 集成流程
45 |
46 | **手动集成**
47 |
48 | `添加 SGQRCode 文件夹到工程中`
49 |
50 | **通过 CocoaPods 集成**
51 |
52 | `pod 'SGQRCode', '~> 4.1.0'`
53 |
54 |
55 | **Info.plist 添加以下字段**
56 |
57 | `NSCameraUsageDescription (相机权限访问)`
58 |
59 | `NSPhotoLibraryUsageDescription (相册权限访问)`
60 |
61 |
62 | **引用头文件**
63 |
64 | `#import `
65 |
66 |
67 | **扫描二维码相关代码**
68 | ```Objective-C
69 | // 创建二维码扫描类
70 | scanCode = [SGScanCode scanCode];
71 |
72 | // 预览视图，必须设置
73 | scanCode.preview = self.view;
74 |
75 | // 遵循 SGScanCodeDelegate
76 | scanCode.delegate = self;
77 |
78 | // 遵循 SGScanCodeSampleBufferDelegate
79 | scanCode.sampleBufferDelegate = self;
80 |
81 | // 开启扫描
82 | [scanCode startRunning];
83 |
84 | // 结束扫描
85 | [scanCode stopRunning];
86 | ```
87 |
88 | **Delegate 方法**
89 | ```Objective-C
90 | // SGScanCodeDelegate
91 | - (void)scanCode:(SGScanCode *)scanCode result:(NSString *)result {
92 | <#code#>
93 | }
94 |
95 | // SGScanCodeSampleBufferDelegate
96 | - (void)scanCode:(SGScanCode *)scanCode brightness:(CGFloat)brightness {
97 | <#code#>
98 | }
99 | ```
100 |
101 | **图片中识别二维码方法**
102 | ```Objective-C
103 | [scanCode readQRCode:image completion:^(NSString *result) {
104 | <#code#>
105 | }];
106 | ```
107 |
108 | **生成二维码相关方法**
109 | ```Objective-C
110 | // 普通二维码生成方法
111 | [SGGenerateQRCode generateQRCodeWithData:data size:size];
112 |
113 | // 带 logo 的二维码生成方法
114 | [SGGenerateQRCode generateQRCodeWithData:data size:size logoImage:logoImage ratio:ratio];
115 | ```
116 |
117 |
118 | ## 效果图

120 | 
121 | 
122 | 
123 |
124 |
125 | ## 问题及解决方案
126 |
127 | * 若在使用 CocoaPods 安装第三方时，出现 [!] Unable to find a specification for SGQRCode 提示时，打开终端先输入 pod repo remove master；执行完毕后再输入 pod setup 即可 (可能会等待一段时间)
128 |
129 | * CIDetector 类只能识别图片中的二维码，目前暂不支持识别图片中的条形码 [解决方案](https://juejin.cn/post/6844903910428114952l)
130 |
131 |
132 | ## 更新说明
133 |
134 | * 2021-07-05 ：v3.5.1 版本重构：修复 [#163](https://github.com/kingsic/SGQRCode/issues/163) 问题，更多内容请在 [releases](https://github.com/kingsic/SGQRCode/releases/tag/3.5.1) 中查看
135 |
136 | * 2022-07-16 ：v4.0.0 版本重构：Delegate 取代 Block，新增手动对焦功能，优化拓展扫描视图，更多内容请在 [releases](https://github.com/kingsic/SGQRCode/releases/tag/4.0.0) 中查看
137 |
138 | * 2022-07-16 ：v4.1.0 优化SGScanView内部代码逻辑，修复无扫描线时，导致程序崩溃问题
