视频直播app源码,Swift动态修改Icon,消除系统弹窗

实现

 

1 导入待替换的新图片,放到项目工程新文件夹中;

2 配置 Info.plist 文件:

 

<key>CFBundleIcons</key>
<dict>
    <key>CFBundleAlternateIcons</key>
    <dict>
        <key>icon1</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>icon1</string>
            </array>
            <key>UIPrerenderedIcon</key>
            <false/>
        </dict>
        <key>icon2</key>
        <dict>
            <key>CFBundleIconFiles</key>
            <array>
                <string>icon2</string>
            </array>
            <key>UIPrerenderedIcon</key>
            <false/>
        </dict>
    </dict>
    <key>CFBundlePrimaryIcon</key>
    <dict>
        <key>CFBundleIconFiles</key>
    <array>
        <string>AppIcon60x60</string>
    </array>
    </dict>
</dict>
 

3 通过代码替换

 

       if #available(iOS 10.3, *) {
            if UIApplication.shared.supportsAlternateIcons {
                print("you can change this app's icon")
            }else {
                print("you cannot change this app's icon")
                return
            }
            
            if let name = UIApplication.shared.alternateIconName {
                // CHANGE TO PRIMARY ICON  恢复默认 icon
                UIApplication.shared.setAlternateIconName(nil) { (err:Error?) in
                    print("set icon error:\(String(describing: err))")
                }
                print("the alternate icon's name is \(name)")
            }else {
                // CHANGE TO ALTERNATE ICON 指定icon图标
                UIApplication.shared.setAlternateIconName("icon1") { (err:Error?) in
                    print("set icon error:\(String(describing: err))")
                }
            }
        }
 

 

4 去掉更换图标时的弹框

更换图标时会出现系统弹框,可以使用Runtime来隐藏弹框,这样方便在节日时候程序自动 无感 更改APP 的icon

具体代码如下:

 

extension UIViewController {
  //通过运行时替换系统的present方法
  public class func nkReplaceSystemPresent(){
    let systemSelector = #selector(UIViewController.present(_:animated:completion:))
    let nkSelector = #selector(UIViewController.newPesent(_:animated:completion:))
    let systemMethod = class_getInstanceMethod(self, systemSelector)
    let nkNewMethod = class_getInstanceMethod(self, nkSelector)
      method_exchangeImplementations(systemMethod!, nkNewMethod!)
  }
  @objc public func newPesent(_ vcToPresent:UIViewController, animated flag:Bool, completion: (() ->Void)? = nil) {
    if vcToPresent.isKind(of:UIAlertController.self) {
      let alertController = vcToPresent as? UIAlertController
      if alertController?.title==nil && alertController?.message==nil {
        return
      }
    }
    self.newPesent(vcToPresent, animated: flag)
  }

 

然后在满足需求的控制器中调用即可。

方法如下:

 


    override func viewDidLoad() {
        super.viewDidLoad()
        DH_MyViewController.nkReplaceSystemPresent()
    }
