objective c to pas

https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/index.html#//apple_ref/occ/intfm/UIApplicationDelegate/application:performFetchWithCompletionHandler:

objective-c

 

- (void)application:(UIApplication *)application
performFetchWithCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler

 

 

delphi

 procedure performFetchWithCompletionHandler(self : id; _cmd : SEL; application:    PUIApplication; handler : id );

 

调用setApplicationIconBadgeNumber方法的两种语法

objective-c

[[UIApplication sharedApplication]setApplicationIconBadgeNumber:0];

delphi

function SharedApplication: UIApplication;
begin
Result := TUIApplication.Wrap(TUIApplication.OCClass.SharedApplication);
end;

SharedApplication.setApplicationIconBadgeNumber(0); //进入前台取消应用消息图标
