效果图：压缩很厉害
效果图
<br />
本来是这样子的
<br />
1、UI:ImageView、VisualEffectView、Button、Label
布局如下
UI比较简单，不做介绍
1.1按钮布局，
-
1.创建一个类，继承与UIButton
-
2.重写layoutSubviews
override func layoutSubviews() {
super.layoutSubviews()
self.imageView?.frame = self.bounds
self.titleLabel?.removeFromSuperview()
self.titleLabel?.frame = self.bounds
self.titleLabel?.textAlignment = NSTextAlignment.Center
self.insertSubview(self.titleLabel!, aboveSubview: self.imageView!)
}
<br />
<br />
2、定位、闭包、动画
<br />
2.1 定位、闭包
- 1 创建一个类，继承：ViewController
- 2 import CoreLocatioin
- 3 定义一个CLLocationManager对象
- 4 写一个方法，用于开启定位
- 5 监听回调
- 6 解析并返回
import UIKit
import CoreLocation
/*
plist文件里面加上
NSLocationAlwaysUsageDescription string 你在这里写的内容会提示在弹窗中
NSLocationWhenInUseUsageDescription string 你在这里写的内容会提示在弹窗中
**/
//闭包定义
typealias feedBackBlock = (message : String) -> ()
class LocationViewController: UIViewController , CLLocationManagerDelegate{
var locationManager :CLLocationManager!
var block = feedBackBlock?()
var timer : NSTimer?
override func viewDidLoad() {
super.viewDidLoad()
}
func startLocation(feedBack :feedBackBlock){
block = feedBack
locationManager = CLLocationManager()
locationManager.delegate = self
locationManager.desiredAccuracy = kCLLocationAccuracyBest
locationManager.requestAlwaysAuthorization()
locationManager.startUpdatingLocation()
//模拟定位获取成功
// timer = NSTimer.scheduledTimerWithTimeInterval(0.5, target: self, selector: #selector(self.send), userInfo: nil, repeats: true)
}
func send(){
timer?.invalidate()
timer = nil
block!(message: "来自遥远的国度,手机可获得真实位置")
}
func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
print(error)
}
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
CLGeocoder().reverseGeocodeLocation(manager.location!, completionHandler: {(placemarks, error)->Void in
self.locationManager.stopUpdatingLocation()
if (error != nil) {
print("Reverse geocoder failed with error" + error!.localizedDescription)
return
}
if placemarks!.count > 0 {
let pm = placemarks![0]
self.displayLocationInfo(pm)
} else {
print("Problem with the data received from geocoder")
}
})
}
func displayLocationInfo(placemark: CLPlacemark?) {
if let containsPlacemark = placemark {
if block != nil {
self.block!(message: containsPlacemark.name!)
}
}
}
}
2.2 动画
- 1 把imageView、button、label拖线到ViewController中
- 2 在button的点击事件调用开始定位的方法
startLocation { ( message) in
print(message)
self.address.text = message
let cat = CATransition();
cat.type = "cube"
cat.duration = 1
self.address.layer.addAnimation(cat, forKey: nil)
}
- 3 重写touchesBegan
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
super.touchesBegan(touches, withEvent: event)
let cat = CATransition();
cat.type = "rippleEffect"
cat.duration = 1
view.layer.addAnimation(cat, forKey: nil)
changeBackgroundImage()
}
var item : Int = 1
func changeBackgroundImage(){
item += 1
if item > 6 {
item = 1
}
backgroundImage.image = UIImage(named: "c\(item).jpg")
}
<br />
<br />
简单的介绍一下CATransition
type:动画类型：
kCATransitionFade 交叉淡化过渡
kCATransitionMoveIn 新视图移到旧视图上面
kCATransitionPush 新视图把旧视图推出去
kCATransitionReveal 将旧视图移开,显示下面的新视图
pageCurl 向上翻一页
pageUnCurl 向下翻一页
rippleEffect 滴水效果
suckEffect 收缩效果，如一块布被抽走
cube 立方体效果
oglFlip 上下翻转效果
3 duration：动画时长
4 timingFunction:动画执行（先快后慢，先慢后快……）
5 subType：方向(fromLeft, fromRight, fromTop ,fromBottom)
6 startProgress:开始点 0-1取值
7 endProgress：结束点 0-1取值
OK,到这里功能就完成了，如果项目有需要的时候，就可以把自己创建的ViewController拿走，让后页面中继承他，就可以使用获取定位的方法了
