We can not change the text of cancel button, but the view button text can be changed.
The payload dictionary has a field "action-loc-key", which takes the alternate text for view button.
The payload dictionary can look like,
{
"aps": {
"alert": {
"body": "Bob wants to play poker",
"action-loc-key": "PLAY"
},
"badge": 5,
},
"acme1": "bar",
"acme2": [
"bang",
"whiz"
]
}
Here the text "Bob wants to play poker" will be the body of alert. and there will "cancel" and "PLAY". Here button text view will be replaced by "PLAY".
