IPhone – How to hide names from incoming messages on whatsapp on the iphone5

There is an option to "show preview" that can be ticked off in the settings of the Messages app: Go to Settings> Notification> Messaging.

Stated another way:

1) Go to Settings = Click on the GEAR icon (System Preferences)

2) The top-most section of System Preferences on My Mac is labeled "Personal" at the far right is "Notifications" (a black square with a red dot in the center)

3) Click that square and the dialogue window will show a list on the left which should include "Messages" with a sub title "Badges and Sounds"

4) Click that item in the list on the left and you will notice on the right side, toward the top it has three options (the default is Banners). Click the item to the left of Banners (should be None).

Now you can press CMD+Q on your keyboard to close System Prefs and the alerts will stop popping up in the upper right of your screen (you may want to test it)

This was an issue for me because I was allowing one of my staff to use my Macbook for some training and all my personal iMessages kept popping up in front of her - NOT COOL. This ended that problem

I have a solution that I was able to reverse engineer. I've tested it on my machine, running Yosemite 10.10.4 (14E46). If you can find the bundle ID (in the Info.plist file for the app bundle), you can use this script to force the app to appear in the notifications preferences pane.

# "Usernoted" seems to be the "user notifications daemon", so get it's PID.
pid=$(ps aux | grep -i [u]sernoted | awk '{print $2}')

# Find the sqlite3 database that this program has open. It's in a "private" folder (app sandboxing).
db="$(lsof -p $pid | grep com.apple.notificationcenter/db/db\$ | awk '{print $9}')"

# I got the bundleid from Spotify.app/Contents/Info.plist
bundleid="com.spotify.client"

# I use 0 as the flags because you can change all the settings in System Preferences
# 5 seems to be the default for show_count
# Grab the next-highest sort order
sql="INSERT INTO app_info (bundleid, flags, show_count, sort_order) VALUES ( '$bundleid', 0, 5, (SELECT MAX(sort_order) + 1 FROM app_info) );"

# Run the command
sqlite3 "$db" "$sql"

# Restart usernoted to make the changes take effect
killall usernoted

At this point you can open System Preferences -> Notifications, and you will find the app that you just added at the bottom of the list. You can enable / disable badging the icon from this page.
