View encapsulation, xib and stroryboard loading and use

A. View Package:

Code implementation:

-(Instancetype) init

{

if (self = [super init]) {

1. Add a Uiimageview object to display a picture of the item

Uiimageview *iconview = [[Uiimageview alloc] init];

[Self addsubview:iconview];

Self.iconview = IconView;

2. Add Uilabel object to display the name of the product

UILabel *titlelabel = [[UILabel alloc] init];

Titlelabel.textalignment = Nstextalignmentcenter;

[Self Addsubview:titlelabel];

Self.titlelabel = Titlelabel;

}

return self;

}

-(void) layoutsubviews

{

[Super Layoutsubviews];

1. Remove the width and height of the current control

CGFloat width = self.frame.size.width;

CGFloat height = self.frame.size.height;

2. Adjust the frame of the child control

Self.iconView.frame = CGRectMake (0, 0, width, width);

Self.titleLabel.frame = CGRectMake (0, Width, width, height-width);

}

Two. Comparison of Xib and Stroyboard

Load Xib

Three. Use MVC's ideas to group code
