swift中UIkit场景转换

如下图创建两个视图，分别有两个按钮分别通往场景 下面有一个连线，连线时modal类型的



那去了B场景怎么回呢！虽然我门也可以通过连线来去B场景但不介意这样做（先练两种方法去a场景）



第一种方法如上图在b场景中写一个方法gotoA（）

第二种方法在a场景中写一个方法xxxxx（）来实现

在b场景中有一个

这样的图片右键就能和A场景关联了

下面是A场景的视图控制器Aview

import UIKit
class Aview:UIViewController {

override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let dest = segue.destinationViewController as! Bview
dest.testName = "kangkang"

}
@IBAction func xxxxxx(xxx:UIStoryboardSegue){

let source = xxx.sourceViewController as! Bview
let data = source.toAdate

print(data)

}

}

下面是Bview

import UIKit

class Bview:UIViewController{

@IBOutlet weak var lablename: UILabel!

var testName:String?
var toAdate:String?
override func viewDidLoad() {
super.viewDidLoad()
lablename.text = testName
}
override func didReceiveMemoryWarning() {

super.didReceiveMemoryWarning()
}
@IBAction func goToA(sender:UIButton){

dismissViewControllerAnimated(true, completion: nil)

}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
toAdate = "toadate ...."
}

}

哦！上面还有一个方法！那是在转换之前做的方法prepareForSegue（）

接下来的是导航视图控制器Navigation controller



行样式

连线是用push的

下面我就来用视图控制器来视图控制器来做一个综合案例吧



如上图一样！一个列表和详情页

列表页的视图控制器

import UIKit

class myviewcontroll :UITableViewController{
var person:[Person]!

var per:Person?
override func viewDidLoad() {
super.viewDidLoad()
person = PersonImpl().generatePerson()

}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return person.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("demo")!
let p = person[indexPath.row]
let nameLabel = cell.viewWithTag(1) as! UILabel
nameLabel.text = p.name
let ageLabel = cell.viewWithTag(2) as! UILabel
ageLabel.text = "\(p.age)"

return cell
}

override func tableView(tableView: UITableView, willSelectRowAtIndexPath indexPath: NSIndexPath) -> NSIndexPath? {

per = person[indexPath.row]

return indexPath
}

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
let dest = segue.destinationViewController as! myviewdetil
dest.person=per!

}

}

详情页的视图控制器

import UIKit

class myviewdetil:UIViewController{

@IBOutlet weak var personname: UILabel!
@IBOutlet weak var personage: UILabel!

var person:Person?

override func viewDidLoad() {
super.viewDidLoad()
personname.text = person?.name
personage.text = "\(person!.age)"
}

}

写一个Person类来存数据

import UIKit

//模型类
class Person {
var name: String
var age: Int
init(name: String,age: Int){
self.name = name
self.age = age
}

}
// PersonBLL
class PersonImpl {
func generatePerson() -> [Person] {
//persondao. //persondal.()
var result = [Person]()
let p = Person(name: "kangkang", age: 11)
result.append(p)

let p2 = Person(name: "lucy", age: 22)
result.append(p2)

let p3 = Person(name: "rose", age: 33)
result.append(p3)
return result

}
}

关于表格的单选。写一个像列表的视图控制器如上面的列表。person类和上面的一样

import UIKit

class RadioSelect: UITableViewController {

var person:[Person]!
override func viewDidLoad() {
super.viewDidLoad()
person = PersonImpl().generatePerson()

}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

return person.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("demo")!
let p = person[indexPath.row]
let nameLabel = cell.viewWithTag(1) as! UILabel
nameLabel.text = p.name
let ageLabel = cell.viewWithTag(2) as! UILabel
ageLabel.text = "\(p.age)"

return cell
}

override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

//取消选中单元格样式
tableView.deselectRowAtIndexPath(indexPath, animated: true)

let cell:UITableViewCell!=tableView.cellForRowAtIndexPath(indexPath)
var arr=tableView.visibleCells
//遍历取消所有单元格样式

for(var i=0 ; i < arr.count ; i++){

let cells = arr[i]
cells.accessoryType = UITableViewCellAccessoryType.None
}
//设置选中的单元格样式

cell.accessoryType = UITableViewCellAccessoryType.Checkmark

}

}

多选

import UIKit

class Duoxuan: UITableViewController {

var person:[Person]!

override func viewDidLoad() {
super.viewDidLoad()
person = PersonImpl().generatePerson()

}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {

return person.count
}

override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("demo")!
let p = person[indexPath.row]
let nameLabel = cell.viewWithTag(1) as! UILabel
nameLabel.text = p.name
let ageLabel = cell.viewWithTag(2) as! UILabel
ageLabel.text = "\(p.age)"

return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
let cell = tableView.cellForRowAtIndexPath(indexPath)
if(cell?.accessoryType == UITableViewCellAccessoryType.Checkmark)
{
cell?.accessoryType = UITableViewCellAccessoryType.None
}
else{
cell?.accessoryType = UITableViewCellAccessoryType.Checkmark
}
}

}
