ios-solve the problem of iOS8 and above settings Applicationiconbadgenumber error

Uiusernotificationsettings *settings = [uiusernotificationsettings settingsfortypes: Uiusernotificationtypebadge Categories:nil]; [[UIApplication sharedapplication] registerusernotificationsettings:settings];

However, if the two sentences are running in the IOS7 system, then the error will be, so you need to first determine the iOS version, the complete code is as follows:

float Version = [[[Uidevice Currentdevice] systemversion] floatvalue];     if 8.0 ) {    *settings = [Uiusernotificationsettings settingsfortypes:uiusernotificationtypebadge Categories:nil];    [[UIApplication sharedapplication] registerusernotificationsettings:settings];}

If you are registering a message push, you need to write this:

float Version = [[[Uidevice Currentdevice] systemversion] floatvalue]; if 8.0 ) {    *settings = [Uiusernotificationsettings settingsfortypes:uiusernotificationtypebadge Categories:nil];    [[UIApplication sharedapplication] registerusernotificationsettings:settings];    [Application registerforremotenotifications];}
