passing object between two views (iOS SDK)
What is the best way to pass an object between two views and how would I go about doing so?开发者_高级运维
If you are using two view controllers then making property
will be best way for you.
in .h file
NSString *name;
@property (nonatomic, retain) NSString *name;
and in .m
@synthesize name;
for more how to use property look - http://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/ObjectiveC/Chapters/ocProperties.html#//apple_ref/doc/uid/TP30001163-CH17-SW1
Use the properties declared in each controller.
I'm assuming you have two view controllers, ViewController1
and ViewController2
. In both header files (.h
), add an instance variable:
CustomObject *myObjectToPass;
and also
@property (nonatomic, retain) CustomObject *myObjectToPass;
If you are passing a BOOL, int or float, then do not retain it, for an NSString, use copy
in place of retain
, etc.
In the implementation file (.m
), synthesize the variable:
@synthesize myObjectToPass;
Now you can get and set the object between viewControllers. The best way to do this depends on how they are related (e.g. in a navigationController or a tabBarContoller, etc). This should get you started, though.
