iOS8.4如何删除app?首先如果你要删除普通APP，十分的简单，和以前一样按着不妨，图标上面会出现删除的符号。不过如果你要删除系统自带的App呢?来看下下面的方法来精简系统吧!
一、先把设备进行iOS8.4完美越狱。（iOS8.4越狱教程）
二、连接PP助手等同步工具，进入文件系统(越狱)，开始删除文件：
路径 Library/LaunchDaemons 里面的PLIST文件。

下面是Apple Watch不建议删除，会不断的搜索反而费电。
Apple Watch
/Applications/Bridge.app
/private/var/mobile/Library/SpringBoard/PushStore/com.apple.Bridge.pushstore
/System/Library/AccessibilityBundles/Bridge.axbundle
/private/var/mobile/Library/Preferences/com.apple.Bridge.plist
/System/Library/AccessibilityBundles/WatchKit.axbundle
/System/Library/frameworks/WatchKit.framework
/System/Library/LocationBundles/AppleWatchFaces.bundle
/System/Library/Privateframeworks/BridgePreferences.framework
三、下载删除数组文件(点击这里下载)，解压并替换至【/Applications/Preferences.app/】路径中，这么做是因为在设置里面有些地方会出现上述软件，删除跟上面软件有关的数组就没问题了。
四、完成以上操作之后清理手机缓存，重启手机即可。
