iOS用戶是否打開APP通知開關跳轉到系統的設置界面

1.檢測用戶是否打開推送通知

/**
 系統通知是否打開
 @return 是否打開
 */
//檢測通知是否打開iOS8以后有所變化 所以需要適配iOS7 
+ (BOOL)openThePushNotification{
    if (IOS8) {//IOS8寫的宏
        if ([[UIApplication sharedApplication] currentUserNotificationSettings].types  == UIUserNotificationTypeNone) {
//         未打開通知//這個是個自定義的alertView 當用戶沒有打開推送時  會彈出 可以替換成自己項目里面的彈框 
            openNotifiAlertView *alertView = [[openNotifiAlertView alloc] init];
            alertView.confirmClick = ^{
                if (IOS8) {//iOS8以后跳轉到設置界面的代碼也出現了變化 下面這段代碼是直接跳轉到APP的設置界面
                    //跳入當前App設置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
                }else{
                    //適配iOS7 ,跳入系統設置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:General&path=Reset"]];
                }            };
            [alertView show];
            
            return NO;
        }else{
            
            return YES;
        }
    }else{ // ios7
        if ([[UIApplication sharedApplication] enabledRemoteNotificationTypes]  == UIUserNotificationTypeNone) {
         
            openNotifiAlertView *alertView = [[openNotifiAlertView alloc] init];
            alertView.confirmClick = ^{
                if (IOS8) {
                    //跳入當前App設置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
                }else{
                    //適配iOS7 ,跳入系統設置界面
                    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:General&path=Reset"]];
                }            };
            [alertView show];
            return NO;
        }else{
            
            return YES;
        }
    }

}
