79 | 80 | 81 | ### 关于新版2.0 82 | 83 | * 开源KafkaRefresh纯属自娱自乐。那时较闲。KafkaRefresh有很大不足，如：更细粒度的视觉动画、更规范的API命名、支持Swift、支持更多的自定义...等等。无奈的是，手头事情之多，使之暂无闲心更新2.0。怕是要很久之后吧。 84 | 85 | * 有人问为何要以Kafka命名，Apache基金会开源过一款分布式消息系统也叫做Kafka，KafkaRefresh跟Apache Kafka没任何关系。当时不知道，即使知道，还是会叫KafkaRefresh。其实是个人喜欢的一个作家叫Kafka，KafkaRefresh的内置样式也用了一些我喜欢的人的名字命名，这没什么意义，或许是为了当时的方便罢了。 86 | 87 | ### 不支持嵌套的ScrollView 88 | 89 | ### 特点 90 | * 支持多样式选择与自定义 91 | 92 | > 内置9种动画样式 93 | 94 | * 非刷新状态自动隐藏 95 | 96 | > 即使手动调整过contentInset，依然能够在非刷新状态自动隐藏影。最常见的情况是：当数据量过少，UITableView停止刷新后，用户依旧能看到刷新控件的存在，从而影响的视觉体验。KafkaRefresh首次解决了该问题。 97 | 98 | * 刷新结束时抗抖动 99 | 100 | > 当UIScrollView处于刷新状态，且用户滑动UIScrollView，当刷新结束时，KafkaRefresh不会调整UIScrollView的内容，从而导致页面跳动； 101 | 102 | * 支持设置控件高度 103 | 104 | > `stretchOffsetYAxisThreshold`是根据刷新控件的高度进行的比例调整。如：当设置`stretchOffsetYAxisThreshold`为1.5时，触发刷新的偏移距离将调整为原来的1.5倍。 105 | 106 | * 支持全局配置 107 | 108 | > `KafkaRefreshDefaults`类似一个配置表，通过该配置表配置全局的刷新样式，而无需在每一个页面初始化或者绑定刷新控件。 109 | 110 | * 支持进度回调 111 | 112 | > 实时回调拖拽的偏移比例，对于扩展接口，可根据进度调整动画。该接口的开放可用于扩展更多的刷新东亚样式。 113 | 114 | * 自适应contentInset系统调整与手动调整 115 | 116 | > 自适应iOS7以后UINavigationController自动调整scrollview contentOffset，KafkaRefresh也对iOS 11进行了适配；当您手动设置了contentInset的值，也无需担心KafkaRefresh会影响到视觉效果。 117 | 118 | * 解决刷新状态分组视图悬停问题 119 | 120 | > 即使在列表滑动时，分组视图都将跟随ScrollView滑动（即使处于高速滑动状态下！）。 121 | 122 | * 支持预加载 123 | 124 | 当用户滑动scrollview接近至底部时，将会自动触发刷新，无需用户再滑至底部后拉起scrollview。该功能默认不开启，因为多数人不查看文档便欣然使用改功能，不正确使用极容易引发刷新无法停止。 125 | 126 | 使用预加载功能，请严格按照下面要求使用: 127 | 128 | * ```self.tableView.footRefreshControl.autoRefreshOnFoot = YES;``` 请手动将刷新该属性至为TRUE； 129 | 130 | * 在刷新调用的block块中，严格按下列逻辑编写： 131 | 132 | ```objective-c 133 | if (没有数据需要拼接了) { 134 | [weakSelf.tableView.footRefreshControl endRefreshingAndNoLongerRefreshingWithAlertText:@"no more"]; 135 | } else { 136 | [weakSelf.tableView.footRefreshControl endRefreshingWithAlertText:@"Did load successfully" completion:nil]; 137 | } 138 | ``` 139 | 140 | * 文档覆盖率100%、支持横竖屏切换自适应、iOS 7+。 141 | 142 | 143 | ### 安装 144 | * CocoaPods 145 | ```ruby 146 | pod 'KafkaRefresh' 147 | ``` 148 | 149 | * Carthage 150 | 151 | > 如果您想通过*carthage*安装 , 请您申请一个pull request. 152 | 153 | ### 使用 154 | 155 | ##### 1.引入头文件 156 | ```objective-c 157 | #import "KafkaRefresh.h" 158 | ``` 159 | 160 | ##### 2.初始化控件 161 | * 方式一 162 | ```objective-c 163 | #pragma mark - head 164 | 165 | [self.tableView bindHeadRefreshHandler:^{ 166 | 167 | } themeColor:MainColor refreshStyle:KafkaRefreshStyleAnimatableArrow]; 168 | 169 | #pragma mark - foot 170 | 171 | [self.tableView bindFootRefreshHandler:^{ 172 | 173 | } themeColor:MainColor refreshStyle:KafkaRefreshStyleAnimatableArrow]; 174 | 175 | #pragma mark - auto refresh 176 | 177 | self.tableView.footRefreshControl.autoRefreshOnFoot = YES; 178 | ``` 179 | * 方式二 180 | ```objective-c 181 | KafkaArrowHeader * arrow = [[KafkaArrowHeader alloc] init]; 182 | arrow.refreshHandler = ^{ 183 | //..... 184 | }; 185 | self.tableView.headRefreshControl = arrow; 186 | ``` 187 | 188 | * 方式三 全局配置 189 | ```objective-c 190 | - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 191 | { 192 | [[KafkaRefreshDefaults standardRefreshDefaults] setHeaderDefaultStyle:KafkaRefreshStyleAnimatableRing]; 193 | return YES; 194 | } 195 | 196 | #pragma mark - global 197 | 198 | [self.tableView bindGlobalStyleForFootRefreshHandler:^{ 199 | 200 | }]; 201 | 202 | ``` 203 | ##### 3.手动触发刷新 204 | ```objective-c 205 | [self.tableView.headRefreshControl beginRefreshing]; 206 | [self.tableView.footRefreshControl beginRefreshing]; 207 | ``` 208 | 209 | ##### 4.结束刷新 210 | ```objective-c 211 | 212 | /* 213 | 一般方式结束刷新 214 | */ 215 | - (void)endRefreshing; 216 | 217 | /* 218 | 结束刷新且需要提示文字 219 | */ 220 | - (void)endRefreshingWithAlertText:(NSString *)text completion:(dispatch_block_t)completion; 221 | 222 | /* 223 | 结束刷新且不再需要刷新功能 224 | */ 225 | - (void)endRefreshingAndNoLongerRefreshingWithAlertText:(NSString *)text; 226 | ``` 227 | 228 | ##### 5.重新恢复刷新 229 | 230 | ```objective-c 231 | /** 232 | 当调用过 ‘endRefreshingAndNoLongerRefreshingWithAlertText’, 233 | 且重新需要恢复刷新功能室，调用下面方法 234 | */ 235 | - (void)resumeRefreshAvailable; 236 | ``` 237 | 238 | ### 自定义 239 | 240 | 以KafkaheadRefreshControl为例： 241 | ```objective-c 242 | #import "KafkaheadRefreshControl.h" 243 | @interface CustomHeader : KafkafootRefreshControl 244 | @end 245 | ``` 246 | ```objective-c 247 | @implementation CustomHeader 248 | 249 | - (void)setupProperties 250 | { 251 | [super setupProperties]; 252 | //初始化属性 253 | } 254 | 255 | - (void)kafkaDidScrollWithProgress:(CGFloat)progress max:(const CGFloat)max 256 | { 257 | //进度回调 258 | } 259 | 260 | - (void)kafkaRefreshStateDidChange:(KafkaRefreshState)state 261 | { 262 | [super kafkaRefreshStateDidChange:state]; 263 | } 264 | @end 265 | ``` 266 | 267 | ### FAQ 268 | 269 | * 遇到很多人咨询这样一个问题：上拉加载数据时，调用 `insertRowsAtIndexPaths: withAnimation:`拼接数据，发现tableView刷新过程发生抖动，位置发生偏移。首先申明！这不是KafkaRefresh的原因。如果想要解决这个问题，请设置`tableView.estimatedRowHeight = UITableViewAutomaticDimension;`. 270 | * 关于Bug的提交，请您一定要记住！应该提交基本信息！当前版本号，重现步骤（请不要过于相信您的中文能力，您写一句话我未必能看懂。） 271 | 272 | ### 交流 273 | 274 | > 1. 如需要帮助，请邮件 275 | > 2. 个人精力有限，KafkaRefresh开放的接口足够去扩展更丰富的UI效果，欢迎您参与，并提交pull request 276 | 277 | ### 协议 278 | > KafkaRefresh采用MIT开源协议。 279 | -------------------------------------------------------------------------------- /Demo/.DS_Store:

84 | 85 | ### Features 86 | 87 | * **Built-in rich animation style, support self-customization** 88 | 89 | 90 | * **Non-refresh state hidden automatically** 91 | 92 | > To avoid developers manually adjust contentInset refresh the appearance of the control after the impact of the visual experience;
93 | the most common situation, the absence of data, the bottom of the refresh control is not hidden, the use of KafkaRefresh to avoid the problem. 94 | 95 | * **Anti-dithering at the end of the refresh** 96 | 97 | >When the refresh control finishes refreshing, if UIScrollView is in a scrolling state, KafkaRefresh will adjust the contntOffset that controls the UIScrollView at this time according to the refresh control. 98 | 99 | * **Support setting the offset threshold to trigger refresh** 100 | 101 | >Setting the value of `stretchOffsetYAxisThreshold` can control the refresh pull distance.This property is a ratio relative to the height of the control and must be set greater than 1.0. 102 | 103 | * **Support global setting** 104 | 105 | >KafkaRefreshDefaults is a singleton for global settings 106 | 107 | * **Support progress callback** 108 | 109 | >Real-time callback Drag the offset ratio, for the expansion of the interface, according to the progress of adjustment animation. 110 | 111 | * **Adaptive contentInset system adjustment and manual adjustment** 112 | 113 | >Adaptive UINavigationController for UIScrollView's contentInset property adjustment, even if the contentInset automatically set value, then KafkaRefresh can still adapt this adjustment. 114 | 115 | * **Solve the section view floating problem when refreshing** 116 | 117 | * **Support horizontal and vertical screen switching adaptive** 118 | 119 | >No need to consider in the horizontal and vertical screen refresh refresh problem. 120 | 121 | * **iOS 7+** 122 | 123 | Support iOS 7 above system. Including iPhone X. 124 | 125 | * Support auto refresh 126 | 127 | When the user slides the scrollview to the bottom, the refresh will be triggered automatically, without the user having to slide to the bottom and pull up the scrollview. This feature is not enabled by default, because most people will use the function without viewing the document. If it is not used correctly, it will be easy to cause the refresh to stop. 128 | 129 | Use the preload feature, please strictly follow the requirements below: 130 | 131 | * ```self.tableView.footRefreshControl.autoRefreshOnFoot = YES;``` please set autoRefreshOnFoot TRUE； 132 | 133 | * in refreshHandler，Strictly follow the logic below！ 134 | 135 | ```objective-c 136 | if ({No data needs to be stitched}) { 137 | [weakSelf.tableView.footRefreshControl endRefreshingAndNoLongerRefreshingWithAlertText:@"no more"]; 138 | } else { 139 | [weakSelf.tableView.footRefreshControl endRefreshingWithAlertText:@"did load successfully" completion:nil]; 140 | } 141 | ``` 142 | 143 | * **Document coverage 100%** 144 | 145 | > You can see the use of all methods and classes in the header file. 146 | 147 | 148 | ### Installation 149 | * CocoaPods 150 | ```ruby 151 | pod 'KafkaRefresh' 152 | ``` 153 | 154 | * Carthage 155 | 156 | > If anyone wants to install by *carthage* , please supply a pull request. I'm not using this package manager myself. 157 | 158 | ### Usage 159 | 160 | ```objective-c 161 | #import "KafkaRefresh.h" 162 | ``` 163 | 164 | ##### Initialization 165 | * The first way 166 | ```objective-c 167 | #pragma mark - head 168 | 169 | [self.tableView bindHeadRefreshHandler:^{ 170 | 171 | } themeColor:MainColor refreshStyle:KafkaRefreshStyleAnimatableArrow]; 172 | 173 | #pragma mark - foot 174 | 175 | [self.tableView bindFootRefreshHandler:^{ 176 | 177 | } themeColor:MainColor refreshStyle:KafkaRefreshStyleAnimatableArrow]; 178 | 179 | #pragma mark - auto refresh 180 | 181 | self.tableView.footRefreshControl.autoRefreshOnFoot = YES; 182 | ``` 183 | * The second way 184 | ```objective-c 185 | KafkaArrowHeader * arrow = [[KafkaArrowHeader alloc] init]; 186 | arrow.refreshHandler = ^{ 187 | //to do something... 188 | }; 189 | self.tableView.headRefreshControl = arrow; 190 | ``` 191 | * The third way(global configuration) 192 | ```objective-c 193 | - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 194 | [[KafkaRefreshDefaults standardRefreshDefaults] setHeaderDefaultStyle:KafkaRefreshStyleAnimatableRing]; 195 | return YES; 196 | } 197 | 198 | #pragma mark - global 199 | 200 | [self.tableView bindGlobalStyleForFootRefreshHandler:^{ 201 | 202 | }]; 203 | ``` 204 | ##### Trigger Refresh Manually 205 | 206 | ```objective-c 207 | [self.tableView.headRefreshControl beginRefreshing]; 208 | [self.tableView.footRefreshControl beginRefreshing]; 209 | ``` 210 | 211 | ##### End Refresh 212 | > When you finish refreshing and don't need to show any hints, or any animation, call the following method. 213 | 214 | ```objective-c 215 | - (void)endRefreshing; 216 | ``` 217 | > When you finish the refresh and need to display the prompt message, call the following method. 218 | 219 | ```objective-c 220 | - (void)endRefreshingWithAlertText:(NSString *)text completion:(dispatch_block_t)completion; 221 | ``` 222 | 223 | >When you end the refresh and no longer need to refresh, call the following method. 224 | 225 | ```objective-c 226 | - (void)endRefreshingAndNoLongerRefreshingWithAlertText:(NSString *)text; 227 | ``` 228 | ##### Resume Refresh Available 229 | ```objective-c 230 | /** 231 | After you call ‘endRefreshingAndNoLongerRefreshingWithAlertText’, 232 | you need to resume refresh available 233 | */ 234 | - (void)resumeRefreshAvailable; 235 | ``` 236 | 237 | ### Customize 238 | 239 | Take KafkaheadRefreshControl as an example 240 | ```objective-c 241 | #import "KafkaheadRefreshControl.h" 242 | @interface CustomHeader : KafkafootRefreshControl 243 | @end 244 | ``` 245 | 246 | ```objective-c 247 | @implementation CustomHeader 248 | 249 | - (void)kafkaDidScrollWithProgress:(CGFloat)progress max:(const CGFloat)max{ 250 | //progress callback 251 | } 252 | 253 | - (void)kafkaRefreshStateDidChange:(KafkaRefreshState)state{ 254 | [super kafkaRefreshStateDidChange:state]; 255 | } 256 | @end 257 | ``` 258 | ### Warnings And Precautions 259 | 260 | * Many people asked me a question that tableView jump after called `insertRowAtIndexPath: withRowAnimation:`,That Is Not Bug Of KafkaRefresh. Setting `tableView.estimatedRowHeight = UITableViewAutomaticDimension;` can solve this question when you initialize tableView; 261 | 262 | 263 | * Please update the latest version! 264 | 265 | 266 | ### Communication 267 | > 1. If you need help，please email . 268 | > 2. If you found a bug，and can provide steps to reliably reproduce it, open an issue. 269 | > 3. Personal energy is limited, Kafka provides callback interface enough to increase the richer UI effect, we welcome you to join together and submit the pull request. 270 | 271 | 272 | ### License 273 | > KafkaRefresh is released under the MIT license.
