Pass value-Custom constructor pass-through value

The "W" in with must be capitalized when customizing the constructor

For example: Next_viewcontroller requires a value to be passed from Viewcontroller to Next_viewcontroller

such as: in the Viewcontrolle initialization of the same time passed an array into the next_viewcontroller inside. You first need to customize the constructor in the Next_viewcontroller .

-(Instancetype) Initwithlist: (Nsarray *) list{

self = [super init];

if (self) {

NSLog (@ "%@", list);

}

return self;

}

Initialize the Next_viewcontroller object in Viewcontrolle and give Next_viewcontroller an array, so that when you jump into the Viewcontroller, the array is uploaded to the Next_ Viewcontroller Inside for example:

Nsarray *list = @[@ "meat", @ "dish", @ "Rice"];

Next_viewcontroller *next = [[Next_viewcontroller alloc]initwithlist:list];

[Self.navigationcontroller Pushviewcontroller:next Animated:yes];

So you can upload the list to Next_viewcontroller.
