[英]How to get the badge value of current installation in parse.com for ios?
[英]Installation and badge issue with Parse.com and ios
我在我的ios应用程序(parse.com sdk 1.7.2.2)上使用安装,推送和徽章,我几天前发现了一些内容,将徽章重置为0的代码,如博客文章中所述(旧版本http:// blog .parse.com / announcements / badge-management-for-ios / )
// Clear badge if needed
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
if (currentInstallation.badge != 0) {
currentInstallation.badge = 0;
[currentInstallation saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
if (!succeeded) [ErrorHandler handle:@"save installation failed" forError:error];
}];
}
不再工作,一切都很好(没有Parse错误)但徽章计数保持在数据库中的旧值
在第二次我努力尝试,似乎暂时工作得更好:
PFInstallation *currentInstallation = [PFInstallation currentInstallation];
if (UIApplication.sharedApplication.applicationIconBadgeNumber > 0 || currentInstallation.badge > 0) {
UIApplication.sharedApplication.applicationIconBadgeNumber = 0;
currentInstallation.badge = 0;
[currentInstallation saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
{
if (!succeeded) [ErrorHandler handle:@"save installation failed" forError:error];
}];
}
但这不起作用,
任何想法?
继承我的快速代码,它的工作原理:
// Resets badge number in parse
var installation = PFInstallation.currentInstallation()
if installation.badge != 0 {
installation.badge = 0
installation.saveInBackgroundWithBlock(nil)
}
// Resets badge number in app
if application.applicationIconBadgeNumber > 0 {
application.applicationIconBadgeNumber = 0
}
install.badge和application.applicationIconBadgeNumber setter之间似乎存在依赖关系。 确保始终设置安装似乎可以缓解这个问题。
let pcur = PFInstallation.currentInstallation()
print("current badge = \(pcur.badge)")
if (pcur.badge != 0){
pcur.badge = 0
pcur.saveInBackgroundWithBlock({
(succeeded,error) in
print("badge save success = \(succeeded)")
application.applicationIconBadgeNumber = 0
})
}
使用Parse(1.14.2),Xcode 8和ios 10,添加:
UIApplication.shared.applicationIconBadgeNumber = 0
在AppDelegate类的applicationDidBecomeActive方法内部也会将解析服务器上的徽章重置为零。
