So we provide another API with cache by index path: 29 | 30 | ``` objc 31 | - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { 32 | return [tableView fd_heightForCellWithIdentifier:@"identifer" cacheByIndexPath:indexPath configuration:^(id cell) { 33 | // configurations 34 | }]; 35 | } 36 | ``` 37 | 38 | Or, if your entity has an unique identifier, use cache by key API: 39 | 40 | ``` objc 41 | - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath { 42 | Entity *entity = self.entities[indexPath.row]; 43 | return [tableView fd_heightForCellWithIdentifier:@"identifer" cacheByKey:entity.uid configuration:^(id cell) { 44 | // configurations 45 | }]; 46 | } 47 | ``` 48 | 49 | ## Frame layout mode 50 | 51 | `FDTemplateLayoutCell` offers 2 modes for asking cell's height. 52 | 53 | 1. Auto layout mode using "-systemLayoutSizeFittingSize:" 54 | 2. Frame layout mode using "-sizeThatFits:" 55 | 56 | Generally, no need to care about modes, it will **automatically** choose a proper mode by whether you have set auto layout constrants on cell's content view. If you want to enforce frame layout mode, enable this property in your cell's configuration block: 57 | 58 | ``` objc 59 | cell.fd_enforceFrameLayout = YES; 60 | ``` 61 | And if you're using frame layout mode, you must override `-sizeThatFits:` in your customized cell and return content view's height (separator excluded) 62 | 63 | ``` 64 | - (CGSize)sizeThatFits:(CGSize)size { 65 | return CGSizeMake(size.width, A+B+C+D+E+....); 66 | } 67 | ``` 68 | 69 | ## Debug log 70 | 71 | Debug log helps to debug or inspect what is this "FDTemplateLayoutCell" extention doing, turning on to print logs when "calculating", "precaching" or "hitting cache".Default to "NO", log by "NSLog". 72 | 73 | ``` objc 74 | self.tableView.fd_debugLogEnabled = YES; 75 | ``` 76 | 77 | It will print like this: 78 | 79 | ``` objc 80 | ** FDTemplateLayoutCell ** layout cell created - FDFeedCell 81 | ** FDTemplateLayoutCell ** calculate - [0:0] 233.5 82 | ** FDTemplateLayoutCell ** calculate - [0:1] 155.5 83 | ** FDTemplateLayoutCell ** calculate - [0:2] 258 84 | ** FDTemplateLayoutCell ** calculate - [0:3] 284 85 | ** FDTemplateLayoutCell ** precached - [0:3] 284 86 | ** FDTemplateLayoutCell ** calculate - [0:4] 278.5 87 | ** FDTemplateLayoutCell ** precached - [0:4] 278.5 88 | ** FDTemplateLayoutCell ** hit cache - [0:3] 284 89 | ** FDTemplateLayoutCell ** hit cache - [0:4] 278.5 90 | ** FDTemplateLayoutCell ** hit cache - [0:5] 156 91 | ** FDTemplateLayoutCell ** hit cache - [0:6] 165 92 | ``` 93 | 94 | ## About self-satisfied cell 95 | 96 | a fully **self-satisfied** cell is constrainted by auto layout and each edge("top", "left", "bottom", "right") has at least one layout constraint against it. It's the same concept introduced as "self-sizing cell" in iOS8 using auto layout. 97 | 98 | A bad one :( - missing right and bottom 99 | ![non-self-satisfied](https://github.com/forkingdog/UITableView-FDTemplateLayoutCell/blob/master/Sceenshots/screenshot0.png) 100 | 101 | A good one :) 102 | ![self-satisfied](https://github.com/forkingdog/UITableView-FDTemplateLayoutCell/blob/master/Sceenshots/screenshot1.png) 103 | 104 | ## Notes 105 | 106 | A template layout cell is created by `-dequeueReusableCellWithIdentifier:` method, it means that you MUST have registered this cell reuse identifier by one of: 107 | 108 | - A prototype cell of UITableView in storyboard. 109 | - Use `-registerNib:forCellReuseIdentifier:` 110 | - Use `-registerClass:forCellReuseIdentifier:` 111 | 112 | ## 如果你在天朝 113 | 可以看这篇中文博客： 114 | [http://blog.sunnyxx.com/2015/05/17/cell-height-calculation/](http://blog.sunnyxx.com/2015/05/17/cell-height-calculation/) 115 | 116 | ## Installation 117 | 118 | Latest version: **1.6** 119 | 120 | ``` 121 | pod search UITableView+FDTemplateLayoutCell 122 | ``` 123 | If you cannot search out the latest version, try: 124 | 125 | ``` 126 | pod setup 127 | ``` 128 | 129 | ## Release Notes 130 | 131 | We recommend to use the latest release in cocoapods. 132 | 133 | - 1.6 134 | fix bug in iOS 10 135 | 136 | - 1.4 137 | Refactor, add "cacheByKey" mode, bug fixed 138 | 139 | - 1.3 140 | Frame layout mode, handle cell's accessory view/type 141 | 142 | - 1.2 143 | Precache and auto cache invalidation 144 | 145 | - 1.1 146 | Height cache 147 | 148 | - 1.0 149 | Basic automatically height calculation 150 | 151 | ## License 152 | MIT 153 | 154 | 155 | -------------------------------------------------------------------------------- /Classes/UITableView+FDTemplateLayoutCell.h: -------------------------------------------------------------------------------- 1 | // The MIT License (MIT) 2 | // 3 | // Copyright (c) 2015-2016 forkingdog ( https://github.com/forkingdog ) 4 | // 5 | // Permission is hereby granted, free of charge, to any person obtaining a copy 6 | // of this software and associated documentation files (the "Software"), to deal 7 | // in the Software without restriction, including without limitation the rights 8 | // to use, copy, modify, merge, publish, distribute, sublicense, and/or sell 9 | // copies of the Software, and to permit persons to whom the Software is 10 | // furnished to do so, subject to the following conditions: 11 | // 12 | // The above copyright notice and this permission notice shall be included in all 13 | // copies or substantial portions of the Software. 14 | // 15 | // THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR 16 | // IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, 17 | // FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
