兼容iOS7以上设置推送，跳转app设置界面

1、首先我们要明确推送实际上有2个开关：

（1）iOS系统（APNS协作）

（2）本地（我们自己的）服务器

所以，为了更好的用户体验，并且iOS有限制的情况下：

从关闭到打开，只能跳转APP 在系统设置 里的页面。

从打开到关闭，将是否接收推送的设置传给服务器端，服务器根据设置选择是否发送推送。假如某用户关闭推送，服务就不给改用户发送推送了。

2、另外一个要解决的是跳转iOS7 的app 设置界面的功能，附上代码：

//跳转到当前app的设置推送界面， iOS7的有点问题（未验证能否通过appstore审核）

+ (void)JumpToPushSetting

{

if ([self getOSVersion] >= 8.0f) {

NSURL * url = [NSURL URLWithString:UIApplicationOpenSettingsURLString];

if([[UIApplication sharedApplication] canOpenURL:url]) {

NSURL*url =[NSURL URLWithString:UIApplicationOpenSettingsURLString];

[[UIApplication sharedApplication] openURL:url];

}

}

else {

NSString *destPath = [NSString stringWithFormat:@"prefs:root=NOTIFICATIONS_ID&path=%@", [self getBundleID]];

NSURL*url2=[NSURL URLWithString:destPath];

[[UIApplication sharedApplication] openURL:url2];

}

}

//是否允许推送

+ (BOOL)IsAllowedNotification {

//iOS8 check if user allow notification

if ([self getOSVersion] >= 8.0f) {// system is iOS8

UIUserNotificationSettings *setting = [[UIApplication sharedApplication] currentUserNotificationSettings];

if (UIUserNotificationTypeNone != setting.types) {

return YES;

}

else

return NO;

} else {//iOS7

UIRemoteNotificationType type = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];

if(UIRemoteNotificationTypeNone != type)

return YES;

else

return NO;

}

return NO;

}

//注册推送消息显示方式

+ (void)RegistPushNotificationSettings

{

UIApplication *application = [UIApplication sharedApplication];

//这下面注册，在第一次打开app的时候，会显示给用户
“是否允许推送通知”窗口

if ([application respondsToSelector:@selector(isRegisteredForRemoteNotifications)])

{

//IOS8

//创建UIUserNotificationSettings，并设置消息的显示类类型

UIUserNotificationSettings *notiSettings = [UIUserNotificationSettings settingsForTypes:(UIUserNotificationTypeBadge | UIUserNotificationTypeAlert | UIRemoteNotificationTypeSound) categories:nil];

[application registerUserNotificationSettings:notiSettings];

} else{ // ios7

[application registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound |UIRemoteNotificationTypeAlert)];

}

}

+(NSString*)getAppVersion

{

NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];

//NSString *name = [infoDictionary objectForKey:@"CFBundleDisplayName"];

NSString *version = [infoDictionary objectForKey:@"CFBundleShortVersionString"];

//NSString *build = [infoDictionary objectForKey:@"CFBundleVersion"];

return version;

}

//获取APP本地的bundle ID

+(NSString*)getBundleID

{

NSDictionary *infoDictionary = [[NSBundle mainBundle] infoDictionary];

NSString* bundleID = [infoDictionary objectForKey:@"CFBundleIdentifier"];

return bundleID;

}
