SDWebImageManager *manager = [SDWebImageManager sharedManager]; 73 | 2 UIImage *cachedImage = [manager imageWithURL:url]; // 将需要缓存的图片加载进来 74 | 3 if (cachedImage) { 75 | 4 // 如果Cache命中，则直接利用缓存的图片进行有关操作 76 | 5 // Use the cached image immediatly 77 | 6 } else { 78 | 7 // 如果Cache没有命中，则去下载指定网络位置的图片，并且给出一个委托方法 79 | 8 // Start an async download 80 | 9 [manager downloadWithURL:url delegate:self]; 81 | 10 } 82 | 复制代码 83 | 当然你的类要实现SDWebImageManagerDelegate协议，并且要实现协议的webImageManager:didFinishWithImage:方法。 84 | 85 | 1 // 当下载完成后，调用回调方法，使下载的图片显示 86 | 2 - (void)webImageManager:(SDWebImageManager *)imageManager didFinishWithImage:(UIImage *)image { 87 | 3 // Do something with the downloaded image 88 | 4 } 89 | 3. 独立的异步图像下载 90 | 可能会单独用到异步图片下载，则一定要用downloaderWithURL:delegate:来建立一个SDWebImageDownloader实例。 91 | 92 | 1 downloader =[SDWebImageDownloader downloaderWithURL:url delegate:self]; 93 | 这样SDWebImageDownloaderDelegate协议的方法imageDownloader:didFinishWithImage:被调用时下载会立即开始并完成。 94 | 95 | 4. 独立的异步图像缓存 96 | 97 | SDImageCache类提供一个创建空缓存的实例，并用方法imageForKey:来寻找当前缓存。 98 | 99 | 1 UIImage*myCachedImage = [[SDImageCache sharedImageCache] imageFromKey:myCacheKey]; 100 | 存储一个图像到缓存是使用方法storeImage: forKey: 101 | 102 | 1 [[SDImageCachesharedImageCache] storeImage:myImage forKey:myCacheKey]; 103 | 默认情况下，图像将被存储在内存缓存和磁盘缓存中。如果仅仅是想内存缓存中，要使用storeImage:forKey:toDisk:方法的第三个参数带一负值 104 | 来替代。 105 | 106 |

在实际开发过程中，会有很多相似版本的app开发，相似的app和主app绝大多数功能相同， 这个时候如何最有效的处理多版本app的开发？ 2 | 3 | 4 | 1：评估具体差异后确定是否拆分project还是通过拆分target 5 | 2：对于绝大多数功能相似的情况，采用多Target编译方案来实现更有效率。 6 | 3：如果使用拆分project，需要选择大小合适的粒度去抽取app的公共的功能模块。 7 | 8 | 9 | ## 多target在不修改代码的情况下如何解决版本差异 10 | > 思路主要是修改target的编译文件，同一个文件名去对应不同路径下的文件进行编译，这样做的好处就是无需改一行代码，通过设置target就可以做的不同target对应不同的代码和资源文件 11 | 12 | ### 修改资源文件引用 13 | 14 | 15 | 选择对应的target -> build phases -> copy bundle resouces 修改指定版本对应的图片路径。 16 | 17 | 通过这种方式能解决不同版本编译出来的appui界面对应的差异。 18 | 19 | 此外，修改还可以修改不同targets对应不同的图标icon和启动画面 20 | ```` 21 | 1：Asset xcassets -> App Icons & launch Images -> New Ios App Icon 22 | 2：general -> App Icons & launch Images -> 选择对应的icons和启动images 23 | ```` 24 | 25 | 26 | ### 修改源代码引用 27 | 28 | 选择对应的target -> build phases -> compile source 修改指定版本对应编译文件路径。 29 | 30 | 通过这种方式能解决不同版本编译出来的app代码的差异 31 | 32 | 也可以通过xcode属性菜单中选择文件所属的target，这种方式更快捷一些。 33 | 34 | 35 | ### 修改pch文件的引用 36 | 可以定义多个pch文件，并在target -> build setting -> prefix header,修改不同target对应的pch文件路径 37 | 38 | 39 | ### 其他 40 | 此外还可以设置target对应不同的项目和库文件，启动前脚本等方式，实现版本差异 41 | 42 | 43 | ## 修改代码解决版本差异 44 | > 这种方式解决不同target更直接,不用改动整个文件，只需要对应改动部分代码段就好了，我们利用xcode target中的preprocessor macros来实现. 45 | 46 | 选择对应的target -> build setting -> preprocessor macros，定义对应版本的宏，然后再代码中判断宏，处理不同代码逻辑。这种方式并不是常规做法，简单，最适合做开关控制。 47 | 48 | ### 例子 49 | 50 | 1：在preprocessor macros中添加一个键，IS_XG=1 51 | 2：在代码中判断是否有这个开关 52 | 53 | ````objc 54 | //打印ccsc版本信息 55 | #ifdef IS_XG 56 | NSLog(@"ccsc星光版本"); 57 | #else 58 | NSLog(@"不是ccsc星光版本"); 59 | #endif 60 | ```` 61 | 62 | 63 | 64 | ## 注意点 65 | 66 | - 1.当你将新文件添加到项目时，别忘了同时选择多个Targets，保持代码在两个版本中同步。 67 | - 2.如果你使用Cocoapods，别忘了将新的target添加到podfile。你可以使用 link_with来指定多个targets。你可以进一步查询Cocoapods documentation了解更多细节。你的podfile看起来应该像这样 68

4 | 5 | n C, using a previously undeclared function constitutes an implicit declaration of the function. In an implicit declaration, the return type is int if I recall correctly. Now, GCC has built-in definitions for some standard functions. If an implicit declaration does not match the built-in definition, you get this warning. 6 | 7 | To fix the problem, you have to declare the functions before using them; normally you do this by including the appropriate header. I recommend not to use the -fno-builtin-* flags if possible. 8 | 9 | Instead of stdlib.h, you should try 10 | 11 | ```` #include ```` 12 | 13 | That's where strcpy and strncpy are defined, at least according to the strcpy(2) man page. 14 | 15 | The exit function is defined in stdlib.h, though, so I don't know what's going on there. 16 | 17 | ## 错误 implicitly declaring library function 'objc_xxxxxx' with type .... 18 | > xxxx可以表示各种运行时错误 19 | 20 | 解决方法：添加头文件 21 | 22 | ````#import ```` -------------------------------------------------------------------------------- /3_Other/开发者账号和证书/AppStore发布成功后如何找到应用的下载地址.md: -------------------------------------------------------------------------------- 1 | ## 如何找到应用的下载地址： 2 | 3 | http://itunes.apple.com/cn/app/id111111 4 | 把id改成你自己应用的id就可以，应用id在itunesconnect里面申请之后就生成了 -------------------------------------------------------------------------------- /3_Other/开发者账号和证书/IOS 真机调试.md: -------------------------------------------------------------------------------- 1 | ## IOS 真机调试 2 | 3 | - 1：注册手机 uuid 4 | 选择Devices ，按步骤输入数据。 5 | 6 | - 2：创建Identifiers 7 | 输入Identifiers 选择权限 8 | 9 | - 3：创建电脑调试的证书 Certificates 10 | 根据自己电脑的钥匙串生成开发电脑需要的Certificates 11 | 12 | - 4: 创建手机调试的证书 Provisioning Profiles 13 | 根据申请好的，Identifiers，选择可以调试的电脑和设备，其实就是把开发环境和开发设备已经Identifiers三者进行绑定 14 | 15 | - 5: 推送和证书多机器开发需要用到.p12证书，导出方式: 16 | 选择 钥匙串 -> 左侧选择登陆和我的证书 ->右侧找到相应的证书后右键点击 -> 导出 -> 选择.p12 17 | 18 | ## 参考网站 19 | 20 | [iOS开发：创建真机调试证书](http://jingyan.baidu.com/article/ff411625b8141312e48237a7.html) 21 | -------------------------------------------------------------------------------- /3_Other/开发者账号和证书/Xcode因为证书问题常见错误.md: -------------------------------------------------------------------------------- 1 | ## Xcode因为证书问题常见错误 2 | 3 | ### ![](http://upload-images.jianshu.io/upload_images/200100-3a8214825f9927f2.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 4 | 5 | Could not launch "xxxxxx" 6 | 7 | > process launch failed : security 8 | 9 | 确认下证书是不是开发证书，如果是发布证书就会出现这样的提示。 10 | 11 | 12 | ### ![](http://upload-images.jianshu.io/upload_images/200100-1a8238279a068561.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 13 | 14 | 证书失效了，去开发者中心重新生成一个 15 | 16 | ### ![](http://upload-images.jianshu.io/upload_images/200100-5a52f5d070a03ff4.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 17 | 18 | 包标识符不与描述文件包含的包标识符不一致，按照它的提示换一下就好了，最好不要点 Fix Issue，点完后 Xcode 会自己生成一个包含统配包标识符的描述文件，并且 Remove 已经生成好的描述文件。会影响整个团队的合作。 19 | 20 | 21 | ### process launch failed: timed out trying to launch app 22 | 23 | 还是描述文件的问题，把发布的描述文件或者是 hoc 的描述文件当成开发描述文件使用了。stackoverflow的解释 24 | 25 | ### This application's application-identifier entitlement does not match that of the installed application.

31 | } 32 | //Do something important 33 | } 34 | ```` 35 | - 复杂的表达式应该拆分多个语义更明确的字句 36 | - 三元运算符 ? 应该只用在它能让代码更加清楚的地方 37 | - 注意stong，weak，copy，assign的正确使用 38 | - 尽量避免使用c的基本类型 ，例如： 39 | 40 | ````objc 41 | int -> NSInteger 42 | unsigned -> NSUInteger 43 | float -> CGFloat 44 | 动画时间 -> NSTimeInterval 45 | enum -> NS_ENUM 46 | ```` 47 | - 合理使用参数断言，当特定参数的条件不满足时，使用 ```` NSParameterAssert()```` 来断言条件是否成立或是抛出一个异常 48 | - 工厂方法或类构造器方法，返回类型需要使用instancetype而不要用id类型，方法中需要使用 [[xxx class]alloc] init]方法构造对象而不要用[[XXXClass alloc]init] 49 | - 永远不要在```` init dealloc ````方法中使用 getter，setter，.属性等，你应当直接访问实例变量 50 | - 类的构成方法（init方法）需要遵守Designated Secondary原则。这点在swift中被强制规定init和convenience构造方法。 51 | 52 | ```` 53 | designated 初始化方法一般提供所有的参数，有且只有一个，而secondary 初始化方法是一个或多个，并且提供一个或者更多的默认参数来调用 designated初始化方法 54 | ```` 55 | - 定义你的 designated initializer，确保调用了直接超类的 designated initializer。 56 | - 重载直接超类的 designated initializer。调用你的新的 designated initializer。 57 | - 为新的 designated initializer 写文档。 58 | - 永远不从 designated initializer 里面调用一个 secondary initializer 59 | - 注意初始化模式的合理使用（类簇，单例） 60 | - 合理使用懒加载Lazy loading 61 | 62 | ```` 63 | 当实例化一个对象需要耗费很多资源，或者配置一次就要调用很多配置相关的方法而你又不想弄乱这些方法时，我们需要重写 getter 方法以延迟实例化 64 | ```` 65 | - 要重写类的相等性时，需要同时实现isEqual和hash方法 66 | - 常量推荐静态常量的声明，如果要暴露给外部，使用extern关键词，例如： 67 | 68 | ````objc 69 | extern NSString *const ZOCCacheControllerDidClearCacheNotification; 70 | static NSString * const ZOCCacheControllerDidClearCacheNotification = @"ZOCCacheControllerDidClearCacheNotification"; 71 | ```` 72 | - 定义你自己的 NSNotification 的时候你应该把你的通知的名字定义为一个字符串常量 73 | 74 | ````objc 75 | // Foo.h 76 | extern NSString * const ZOCFooDidBecomeBarNotification 77 | // Foo.m 78 | NSString * const ZOCFooDidBecomeBarNotification = @"ZOCFooDidBecomeBarNotification";
