addSubview in UIAlertView deprecated in iOS7

There is a solution....

UIAlertView *alertView;

//a simple alert view with a simple message:

alertView = [[UIAlertView alloc]initWithTitle:nil message:@"My message here..." delegate:self cancelButtonTitle:nil otherButtonTitles:nil];

    

//a simple activity indicator:

UIActivityIndicatorView *activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];

activityIndicator.frame= CGRectMake(50, 10, 37, 37);

activityIndicator.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleLeftMargin;    

[activityIndicator startAnimating];

//the magic line below,   

//we associate the activity indicator to the alert view: (addSubview is not used)

[alertView setValue:activityIndicator forKey:@"accessoryView"];

    

[alertView show];

[Knockout] How to define which properties are serialized in JSON ?

//we have a person structure, with a first name, a last name, 
//and a full name (computed field) :
function Person(first, last) {    
    this.first = ko.observable(first);    
    this.last = ko.observable(last);    
    this.full = ko.computed(function() {
        return this.first() + " " + this.last();
    }, this);
}

• Solution 1

//we define which properties are serialized in JSON 
//(in this case, only full) and how they are serialized 
//(in this case, a simple string) :
Person.prototype.toJSON = function() {
   //only full :
   return ko.utils.unwrapObservable(this.full); // we return a string of the value
};
var person=new Person("a","b");
console.log(ko.toJSON(person)); 
// => it will generate : "a b"

• Solution 2

//we define which properties are serialized in JSON 
//(in this case, first + last name):
Person.prototype.toJSON = function() {
    var copy = ko.toJS(this); //easy way to get a clean copy
    delete copy.full; //remove an extra property
    return copy; //return the copy to be serialized
};
var person=new Person("a","b");
console.log(ko.toJSON(person)); 
// => it will generate : {"first":"a", "last":"b"}
