我正在尝试在注册视图控制器中创建profilePic. profilePic的类型为UI
ImageView.我希望能够点击它,以便立即在ActionSheet样式中提取照片库.并且还有一个图像框一个按钮来访问相机.这可能吗？
import UIKit
class SignUpViewController: UIViewController,UITextFieldDelegate,UIPickerViewDataSource,UIPickerViewDelegate {
@IBOutlet weak var profilePic: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
// PROFILE PICTURE
let tapGesture = UITapGestureRecognizer(target: self,action: "imageTapped:")
profilePic.addGestureRecognizer(tapGesture)
profilePic.userInteractionEnabled = true
}
func imageTapped(gesture:UIGestureRecognizer) {
if let profile1Pic = gesture.view as? UIImageView {
print("Image Tapped")
}
}
解决方法
请尝试以下代码：
import UIKit
class SignUpViewController: UIViewController,UIImagePickerControllerDelegate {
@IBOutlet weak var profilePic: UIImageView!
override func viewDidLoad() {
super.viewDidLoad()
let tapGesture = UITapGestureRecognizer(target: self,action: "imageTapped:")
profilePic.addGestureRecognizer(tapGesture)
profilePic.userInteractionEnabled = true
}
func imageTapped(gesture:UIGestureRecognizer) {
if let profile1Pic = gesture.view as? UIImageView {
print("Image Tapped")
showActionSheet()
}
}
func camera()
{
var myPickerController = UIImagePickerController()
myPickerController.delegate = self;
myPickerController.sourceType = UIImagePickerControllerSourceType.Camera
self.presentViewController(myPickerController,animated: true,completion: nil)
}
func photoLibrary()
{
var myPickerController = UIImagePickerController()
myPickerController.delegate = self;
myPickerController.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
self.presentViewController(myPickerController,completion: nil)
}
func showActionSheet() {
let actionSheet = UIAlertController(title: nil,message: nil,preferredStyle: UIAlertControllerStyle.ActionSheet)
actionSheet.addAction(UIAlertAction(title: "Camera",style: UIAlertActionStyle.Default,handler: { (alert:UIAlertAction!) -> Void in
self.camera()
}))
actionSheet.addAction(UIAlertAction(title: "Gallery",handler: { (alert:UIAlertAction!) -> Void in
self.photoLibrary()
}))
actionSheet.addAction(UIAlertAction(title: "Cancel",style: UIAlertActionStyle.Cancel,handler: nil))
self.presentViewController(actionSheet,completion: nil)
}
func imagePickerController(picker: UIImagePickerController,didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
profilePic.image = info[UIImagePickerControllerOriginalImage] as? UIImage
self.dismissViewControllerAnimated(true,completion: nil)
}
}
