Follow the [instructions](https://github.com/Carthage/Carthage#if-youre-building-for-ios) to add `$(SRCROOT)/Carthage/Build/iOS/GDPerformanceView.framework` to an iOS project. 22 | 23 | ```ruby 24 | github "dani-gavrilov/GDPerformanceView-Swift" ~> 2.1.1 25 | ``` 26 | Don't forget to import GDPerformanceView by adding: 27 | 28 | ```swift 29 | import GDPerformanceView 30 | ``` 31 | 32 | #### CocoaPods 33 | You can use [CocoaPods](http://cocoapods.org/) to install `GDPerformanceView` by adding it to your `Podfile`: 34 | 35 | ```ruby 36 | platform :ios, '8.0' 37 | use_frameworks! 38 | 39 | target 'project_name' do 40 | pod 'GDPerformanceView-Swift', '~> 2.1.1' 41 | end 42 | ``` 43 | Don't forget to import GDPerformanceView by adding: 44 | 45 | ```swift 46 | import GDPerformanceView_Swift 47 | ``` 48 | 49 | ## Usage example 50 | 51 | Simply start monitoring. Performance view will be added above the status bar automatically. 52 | Also, you can configure appearance as you like or just hide the monitoring view and use its delegate. 53 | 54 | You can find example projects [here](https://github.com/dani-gavrilov/GDPerformanceViewExamples). 55 | 56 | #### Start monitoring 57 | 58 | By default, monitoring is paused. Call the following command to start or resume monitoring: 59 | 60 | ```swift 61 | PerformanceMonitor.shared().start() 62 | ``` 63 | or 64 | 65 | ```swift 66 | self.performanceView = PerformanceMonitor() 67 | self.performanceView?. start() 68 | ``` 69 | This won't show the monitoring view if it was hidden previously. To show it call the following command: 70 | 71 | ```swift 72 | self.performanceView?.show() 73 | ``` 74 | 75 | #### Pause monitoring 76 | 77 | Call the following command to pause monitoring: 78 | 79 | ```swift 80 | self.performanceView?.pause() 81 | ``` 82 | 83 | This won't hide the monitoring view. To hide it call the following command: 84 | 85 | ```swift 86 | self.performanceView?.hide() 87 | ``` 88 | 89 | #### Displayed information 90 | 91 | You can change displayed information by changing options of the performance monitor: 92 | 93 | ```swift 94 | self.performanceView?.performanceViewConfigurator.options = .all 95 | ``` 96 | You can choose from: 97 | 98 | * performance - CPU usage and FPS. 99 | * memory - Memory usage. 100 | * application - Application version with build number. 101 | * device - Device model. 102 | * system - System name with version. 103 | 104 | Also you can mix them, but order doesn't matter: 105 | 106 | ```swift 107 | self.performanceView?.performanceViewConfigurator.options = [.performance, .application, .system] 108 | ``` 109 | By default, set of [.performance, .application, .system] options is used. 110 | 111 | You can also add your custom information by using: 112 | 113 | ```swift 114 | self.performanceView?.performanceViewConfigurator.userInfo = .custom(string: "Launch date \(Date())") 115 | ``` 116 | Keep in mind that custom string will not automatically fit the screen, use `\n` if it is too long. 117 | 118 | #### Appearance 119 | 120 | You can change monitoring view appearance by changing style of the performance monitor: 121 | 122 | Call the following command to change output information: 123 | 124 | ```swift 125 | self.performanceView?.performanceViewConfigurator.style = .dark 126 | ``` 127 | 128 | You can choose from: 129 | 130 | * dark - Black background, white text. 131 | * light - White background, black text. 132 | * custom - You can set background color, border color, border width, corner radius, text color and font. 133 | 134 | By default, dark style is used. 135 | 136 | Also you can override prefersStatusBarHidden and preferredStatusBarStyle to match your expectations: 137 | 138 | ```swift 139 | self.performanceView?.statusBarConfigurator.statusBarHidden = false 140 | self.performanceView?.statusBarConfigurator.statusBarStyle = .lightContent 141 | ``` 142 | 143 | #### Interactions 144 | 145 | You can interact with performance view via gesture recognizers. Add them by using: 146 | 147 | ```swift 148 | self.performanceView?.performanceViewConfigurator.interactors = [tapGesture, swipeGesture] 149 | ``` 150 | If interactors is nil or empty `point(inside:with:)` of the view will return false to make all touches pass underneath. So to remove interactors just call the following command: 151 | 152 | ```swift 153 | self.performanceView?.performanceViewConfigurator.interactors = nil 154 | ``` 155 | By default, interactors are nil. 156 | 157 | #### Delegate 158 | 159 | Set the delegate and implement its method: 160 | 161 | ```swift 162 | self.performanceView?.delegate = self 163 | ``` 164 | 165 | ```swift 166 | func performanceMonitor(didReport performanceReport: PerformanceReport) { 167 | print(performanceReport.cpuUsage, performanceReport.fps, performanceReport.memoryUsage.used, performanceReport.memoryUsage.total) 168 | } 169 | ``` 170 | 171 | ## Requirements 172 | - iOS 9.0+ 173 | - xCode 12.0+ 174 | 175 | ## Donations 176 | 177 | Wanna say thanks?
