A Constructor in C is used in the memory management of C++programming. It allows built-in data types like int, float and user-defined data types such as class. Constructor in Object-oriented programming initializes the variable of a user-defined data type. Constructor helps in the creation of an object.
In Objective-C you would do so in the init method even though you create a convenience constructor. The convenience constructor as the name suggests is a shortcut so you don't have to write out two statements namely: alloc and init.
The Objective-C declared properties feature provides a simple way to declare and implement an object's accessor methods.
Test example = [[Test alloc] init]; example.name = @"s"; you can write something like this: Test example = [[Test alloc] initWithName:@"s"]; Please note that this is very common for initialization method to return newly created object, hence the initialization method usually returns 'id' type (not void).
I have this class:
@interface RSSEntry : NSObject{
NSString *blogTitle;
NSString *articleTitle;
NSString *articleUrl;
NSDate *articleDate;
}
@property (copy) NSString *blogTitle;
@property (copy) NSString *articleTitle;
@property (copy) NSString *articleUrl;
@property (copy) NSDate *articleDate;
@end
Now, how will I make these member variables get initialized when creating an object, especially when ARC is enabled in the Xcode project? I'm new to Objective-C; I'm looking for something like constructor from C base languages.
