Develop the iOS App using the Swift - Part #3

New Features

• What feature(s) did you add?

Encapsulate functionView

• How did you implement it/them?

Given the frequent use of functionView in projects, in order to simplify the amount of code in the project, we simply encapsulated functionView.

This is it.

Before, we put all the buttons in the same xib file.

This will not be able to deal with multiple different scenarios.

So we use each button as a separate class: STMainFunctionItem

func setSubViews(title:String,imageName:String) {
        self.setSubViews(title: title, imageName: imageName, target: nil, selector: nil)
    }    
func setSubViews(title:String,imageName:String,target:Any?,selector:Selector?) {
        titleLab.text = title
        DesImgV.image = UIImage.init(named: imageName)
        self.selector = selector
        self.target = target
}

Created by the above two initialization methods.

In the STMainCellFunctionView class, load each item as follows.

Control each item constraint through the snap framework.

func setFunctionItem(items:[STMainFunctionItem]) {
        self.items = items
        // Add view
        for item in items {
            self.addSubview(item)
        }        
        // Add constraints
        for (idx, item) in items.enumerated() {
            item.snp.makeConstraints({ (make) in
                // left
                if idx == 0{
                    make.left.equalTo(self.snp.left).offset(0)
                }else{
                    make.left.equalTo(items[idx - 1].snp.right).offset(0)
                    //width
                    make.width.equalTo(items[idx - 1].snp.width)
                }                
                // right
                if idx == items.count - 1 {
                    make.right.equalTo(self.snp.right).offset(0)
                }else{
                    make.right.equalTo(items[idx + 1].snp.left).offset(0)
                }                
                // top
                make.top.equalTo(self.snp.top).offset(0)
                // bottom
                make.bottom.equalTo(self.snp.bottom).offset(0)
            })
        }
    }
