56 | [self.view addSubview:self.tableView]; 57 | NSLog(@"tableView %f",self.tableView.frame.size.height); 58 | } 59 | 60 | - (UITableView *)tableView { 61 | if (!_tableView) { 62 | _tableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, kScreenWidth, kScreenHeight - NAVHEIGHT - SegmentHeaderViewHeight)]; 63 | // _tableView = [[UITableView alloc] initWithFrame:self.view.bounds]; 64 | _tableView.delegate = self; 65 | _tableView.dataSource = self; 66 | _tableView.showsVerticalScrollIndicator = NO; 67 | _tableView.showsHorizontalScrollIndicator = NO; 68 | _tableView.separatorStyle = UITableViewCellSeparatorStyleSingleLine; 69 | _tableView.rowHeight = 50; 70 | [self.view addSubview:_tableView]; 71 | } 72 | return _tableView; 73 | } 74 | 75 | #pragma mark - UITableViewDataSource 76 | - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 77 | return 50; 78 | } 79 | 80 | - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 81 | static NSString *const FirstViewControllerTableViewCellIdentifier = @"FirstViewControllerTableViewCell"; 82 | UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:FirstViewControllerTableViewCellIdentifier]; 83 | if (cell == nil) { 84 | cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:FirstViewControllerTableViewCellIdentifier]; 85 | } 86 | cell.textLabel.text = [NSString stringWithFormat:@"快点我%ld -> 进入我的消息",indexPath.row]; 87 | return cell; 88 | } 89 | 90 | #pragma mark - UITableViewDelegate 91 | - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 92 | [tableView deselectRowAtIndexPath:indexPath animated:YES]; 93 | 94 | } 95 | 96 | @end 97 | ``` 98 | 99 | 你可以 自定义上半部分视图，如果你也想像我一样支持轮播，并且需要滑动左右轮播，上下滑动整体的话那你需要想我一样把轮播加在YWPageHeadView上面 100 | 例如 101 | ``` 102 | //这是轮播 103 | - (CCPagedScrollView*)imageScrollView{ 104 | if (!_imageScrollView) 105 | { 106 | 107 | _imageScrollView = [[CCPagedScrollView alloc] initWithFrame:CGRectMake(0, 0,kScreenWidth, self.HeaderImageViewHeight) animationDuration:0 isAuto:NO];

144 | [self.view addSubview:self.naviView]; 145 | ``` 146 | 但是如果你不需要轮播的额外处理，上面只是一个图片存在下拉放大等效果，可以不用YWPageHeadView这个类 直接定义视图加在mainTableView上 147 | 148 | 149 | 另外我为了定义的更加灵活，把轮播视图和下面的红色视图分开定义，加在了mainTableView上，这个可以按需求来，你可以灵活使用 150 | 151 | 152 | 153 | #### 因为时间原因，里面的类名什么的就没有进行规范化处理了，如果使您阅读不便，请原谅一下，如果您有什么更好的建议也可以直接联系我， 154 | #### 最后如果您能点下star支持一下，我会非常感谢😁 155 | 156 | 157 | -------------------------------------------------------------------------------- /image/.DS_Store: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/china-han/YWPersonDemo/e9eaab03d106589c58a3bf31321b1d089799e3ac/image/.DS_Store -------------------------------------------------------------------------------- /image/person1.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/china-han/YWPersonDemo/e9eaab03d106589c58a3bf31321b1d089799e3ac/image/person1.gif -------------------------------------------------------------------------------- /image/person2.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/china-han/YWPersonDemo/e9eaab03d106589c58a3bf31321b1d089799e3ac/image/person2.gif -------------------------------------------------------------------------------- /image/个人主页.gif: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/china-han/YWPersonDemo/e9eaab03d106589c58a3bf31321b1d089799e3ac/image/个人主页.gif -------------------------------------------------------------------------------- /个人主页demo.xcodeproj/project.xcworkspace/contents.xcworkspacedata: -------------------------------------------------------------------------------- 1 | 2 | 4 | 6 | 7 | 8 | -------------------------------------------------------------------------------- /个人主页demo.xcodeproj/project.xcworkspace/xcshareddata/IDEWorkspaceChecks.plist: -------------------------------------------------------------------------------- 1 | 2 | 3 | 4 | 5 | IDEDidComputeMac32BitWarning 6 | 7 | 8 | 9 | -------------------------------------------------------------------------------- /个人主页demo/.DS_Store: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/china-han/YWPersonDemo/e9eaab03d106589c58a3bf31321b1d089799e3ac/个人主页demo/.DS_Store -------------------------------------------------------------------------------- /个人主页demo/AppDelegate.h: -------------------------------------------------------------------------------- 1 | // 2 | // AppDelegate.h 3 | // 个人主页demo 4 | // 5 | // Created by hyw on 2018/11/14. 6 | // Copyright © 2018年 bksx.

For convenience, we added categories for UI elements like `UIImageView`, `UIButton`, `MKAnnotationView`. 16 | 17 | ## Features 18 | 19 | - [x] Categories for `UIImageView`, `UIButton`, `MKAnnotationView` adding web image and cache management 20 | - [x] An asynchronous image downloader 21 | - [x] An asynchronous memory + disk image caching with automatic cache expiration handling 22 | - [x] A background image decompression 23 | - [x] A guarantee that the same URL won't be downloaded several times 24 | - [x] A guarantee that bogus URLs won't be retried again and again 25 | - [x] A guarantee that main thread will never be blocked 26 | - [x] Performances! 27 | - [x] Use GCD and ARC 28 | 29 | ## Supported Image Formats 30 | 31 | - Image formats supported by UIImage (JPEG, PNG, ...), including GIF 32 | - WebP format, including animated WebP (use the `WebP` subspec) 33 | 34 | ## Requirements 35 | 36 | - iOS 7.0 or later 37 | - tvOS 9.0 or later 38 | - watchOS 2.0 or later 39 | - OS X 10.8 or later 40 | - Xcode 7.3 or later 41 | 42 | #### Backwards compatibility 43 | 44 | - For iOS 5 and 6, use [any 3.x version up to 3.7.6](https://github.com/rs/SDWebImage/tree/3.7.6) 45 | - For iOS < 5.0, please use the last [2.0 version](https://github.com/rs/SDWebImage/tree/2.0-compat). 46 | 47 | ## Getting Started 48 | 49 | - Read this Readme doc 50 | - Read the [How to use section](https://github.com/rs/SDWebImage#how-to-use) 51 | - Read the [documentation @ CocoaDocs](http://cocoadocs.org/docsets/SDWebImage/) 52 | - Read [How is SDWebImage better than X?](https://github.com/rs/SDWebImage/wiki/How-is-SDWebImage-better-than-X%3F) 53 | - Try the example by downloading the project from Github or even easier using CocoaPods try `pod try SDWebImage` 54 | - Get to the [installation steps](https://github.com/rs/SDWebImage#installation) 55 | - Read the [SDWebImage 4.0 Migration Guide](Docs/SDWebImage-4.0-Migration-guide.md) to get an idea of the changes from 3.x to 4.x 56 | 57 | ## Who Uses It 58 | - Find out [who uses SDWebImage](https://github.com/rs/SDWebImage/wiki/Who-Uses-SDWebImage) and add your app to the list. 59 | 60 | ## Communication 61 | 62 | - If you **need help**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/sdwebimage). (Tag 'sdwebimage') 63 | - If you'd like to **ask a general question**, use [Stack Overflow](http://stackoverflow.com/questions/tagged/sdwebimage). 64 | - If you **found a bug**, open an issue. 65 | - If you **have a feature request**, open an issue. 66 | - If you **want to contribute**, submit a pull request. 67 | 68 | ## Installation 69 | 70 | ## How To Use 71 | 72 | ```objective-c 73 | Objective-C: 74 | 75 | #import 76 | ... 77 | [imageView sd_setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] 78 | placeholderImage:[UIImage imageNamed:@"placeholder.png"]]; 79 | ``` 80 | 81 | ```swift 82 | Swift: 83 | 84 | @import SDWebImage 85 | 86 | imageView.sd_setImage(with: URL(string: "http://www.domain.com/path/to/image.jpg"), placeholderImage: UIImage(named: "placeholder.png")) 87 | ``` 88 | 89 | - For details about how to use the library and clear examples, see [The detailed How to use](Docs/HowToUse.md) 90 | 91 | ## Animated Images (GIF) support 92 | 93 | - Starting with the 4.0 version, we rely on [FLAnimatedImage](https://github.com/Flipboard/FLAnimatedImage) to take care of our animated images. 94 | - To use it, simply make sure you use `FLAnimatedImageView` instead of `UIImageView`. 95 | - **Note**: there is a backwards compatible feature, so if you are still trying to load a GIF into a `UIImageView`, it will only show the 1st frame as a static image. 96 | - **Important**: FLAnimatedImage only works on the iOS platform, so for all the other platforms (OS X, tvOS, watchOS) we will fallback to the backwards compatibility feature described above 97 | 98 | Common Problems 99 | --------------- 100 | 101 | ### Using dynamic image size with UITableViewCell 102 | 103 | UITableView determines the size of the image by the first image set for a cell. If your remote images 104 | don't have the same size as your placeholder image, you may experience strange anamorphic scaling issue. 105 | The following article gives a way to workaround this issue: 106 | 107 | [http://www.wrichards.com/blog/2011/11/sdwebimage-fixed-width-cell-images/](http://www.wrichards.com/blog/2011/11/sdwebimage-fixed-width-cell-images/) 108 | 109 | 110 | ### Handle image refresh 111 | 112 | SDWebImage does very aggressive caching by default. It ignores all kind of caching control header returned by the HTTP server and cache the returned images with no time restriction. It implies your images URLs are static URLs pointing to images that never change. If the pointed image happen to change, some parts of the URL should change accordingly. 113 | 114 | If you don't control the image server you're using, you may not be able to change the URL when its content is updated. This is the case for Facebook avatar URLs for instance. In such case, you may use the `SDWebImageRefreshCached` flag. This will slightly degrade the performance but will respect the HTTP caching control headers: 115 | 116 | ``` objective-c 117 | [imageView sd_setImageWithURL:[NSURL URLWithString:@"https://graph.facebook.com/olivier.poitrey/picture"] 118 | placeholderImage:[UIImage imageNamed:@"avatar-placeholder.png"] 119 | options:SDWebImageRefreshCached]; 120 | ``` 121 | 122 | ### Add a progress indicator 123 | 124 | Add these before you call ```sd_setImageWithURL``` 125 | 126 | ``` objective-c 127 | [imageView setShowActivityIndicatorView:YES]; 128 | [imageView setIndicatorStyle:UIActivityIndicatorViewStyleGray]; 129 | ``` 130 | 131 | ``` swift 132 | imageView.setShowActivityIndicatorView(true) 133 | imageView.setIndicatorStyle(.Gray) 134 | ``` 135 | 136 | Installation 137 | ------------ 138 | 139 | There are three ways to use SDWebImage in your project: 140 | - using CocoaPods 141 | - using Carthage 142 | - by cloning the project into your repository 143 | 144 | ### Installation with CocoaPods 145 | 146 | [CocoaPods](http://cocoapods.org/) is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the [Get Started](http://cocoapods.org/#get_started) section for more details. 147 | 148 | #### Podfile 149 | ``` 150 | platform :ios, '7.0' 151 | pod 'SDWebImage', '~>3.8' 152 | ``` 153 | 154 | If you are using Swift, be sure to add `use_frameworks!` and set your target to iOS 8+: 155 | ``` 156 | platform :ios, '8.0' 157 | use_frameworks! 158 | ``` 159 | 160 | #### Subspecs 161 | 162 | There are 3 subspecs available now: `Core`, `MapKit` and `WebP` (this means you can install only some of the SDWebImage modules. By default, you get just `Core`, so if you need `WebP`, you need to specify it). 163 | 164 | Podfile example: 165 | ``` 166 | pod 'SDWebImage/WebP' 167 | ``` 168 | 169 | ### Installation with Carthage (iOS 8+) 170 | 171 | [Carthage](https://github.com/Carthage/Carthage) is a lightweight dependency manager for Swift and Objective-C. It leverages CocoaTouch modules and is less invasive than CocoaPods. 172 | 173 | To install with carthage, follow the instruction on [Carthage](https://github.com/Carthage/Carthage) 174 | 175 | #### Cartfile 176 | ``` 177 | github "rs/SDWebImage" 178 | ``` 179 | 180 | ### Installation by cloning the repository 181 | - see [Manual install](Docs/ManualInstallation.md) 182 | 183 | ### Import headers in your source files 184 | 185 | In the source files where you need to use the library, import the header file: 186 | 187 | ```objective-c 188 | #import 189 | ``` 190 | 191 | ### Build Project 192 | 193 | At this point your workspace should build without error. If you are having problem, post to the Issue and the 194 | community can help you solve it. 195 | 196 | ## Author 197 | - [Olivier Poitrey](https://github.com/rs) 198 | 199 | ## Collaborators 200 | - [Konstantinos K.](https://github.com/mythodeia) 201 | - [Bogdan Poplauschi](https://github.com/bpoplauschi) 202 | 203 | ## Licenses 204 | 205 | All source code is licensed under the [MIT License](https://raw.github.com/rs/SDWebImage/master/LICENSE). 206 | 207 | ## Architecture 208 | 209 |
