問題描述
限時送ChatGPT賬號..
我已嘗試正確獲取電池電量.但是那個值不像iphone狀態欄中的值.
I have tried to get correctly battery level. But that value is not like value in status bar of iphone.
通過代碼使用 UIDevice:
by code use UIDevice:
[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];
[[UIDevice currentDevice] batteryLevel];
請有人幫助我！我需要獲得正確的電池電量，就像在狀態欄 imdimatery 中一樣.
please someone help me! I need get correctly battery level that like in status bar imdimatery.
推薦答案
Apple 文檔是這樣說的:
Well the Apple docs say this:
電池電量范圍從 0.0(完全放電)到 1.0(100% 充電).在訪問此屬性之前，請確保已啟用電池監控.
Battery level ranges from 0.0 (fully discharged) to 1.0 (100% charged). Before accessing this property, ensure that battery monitoring is enabled.
所以你的代碼應該是這樣的:
So your code should be like this:
[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];
float batteryLevel = [[UIDevice currentDevice] batteryLevel];
//This will give you the battery between 0.0 (empty) and 1.0 (100% charged)
//If you want it as a percentage, you can do this:
batteryLevel *= 100;
希望這會有所幫助！
