UITableViewCell Custom UIImageView
图像： Custom TableViewCell UIImageView
如果单击上面的链接，您将看到在第一行之后，自定义UIImageView被水平剪切，然后在后续行中垂直剪切。关于如何解决这个问题的任何想法？
在viewDidLoad中，我按如下方式更改行高：
// Set cell row height
self.tableView.rowHeight = 60
这里是TableView的代码：
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var count = Int()
if self.names.count != 0 {
count = self.names.count
} else if self.names.count == 0 {
count = 1
}
return count
}
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell : UITableViewCell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as UITableViewCell
for view in cell.contentView.subviews {
// Clear subviews
view.removeFromSuperview()
}
// Customize separator width
tableView.separatorInset = UIEdgeInsetsZero
cell.separatorInset = UIEdgeInsetsZero
cell.layoutMargins = UIEdgeInsetsZero
cell.preservesSuperviewLayoutMargins = false
// Create imageView
let imageView = UIImageView(frame: CGRectMake(10, 5, 50, 50))
imageView.contentMode = UIViewContentMode.ScaleAspectFit
imageView.layer.cornerRadius = 25
imageView.clipsToBounds = true
cell.contentView.addSubview(imageView)
// Create textLabel
let textLabel = UILabel(frame: CGRectMake(70, 10, self.view.frame.width, 20))
textLabel.font = UIFont(name: "Arial", size: 15.0)
textLabel.textAlignment = .Left
cell.contentView.addSubview(textLabel)
// Create lastMessageLabel
let lastMessageLabel = UILabel(frame: CGRectMake(70, 30, self.view.frame.width, 20))
lastMessageLabel.font = UIFont(name: "Arial", size: 12)
lastMessageLabel.textAlignment = .Left
lastMessageLabel.textColor = UIColor.grayColor()
cell.contentView.addSubview(lastMessageLabel)
if self.names.count != 0 {
// Add contact cell
imageView.image = self.images[indexPath.row]
textLabel.text = self.names[indexPath.row] as? String
lastMessageLabel.text = self.lastMessage[indexPath.row] as? String
}
if self.names.count == 0 {
// Add warning
imageView.image = UIImage(named: "user-placeholder.png")
textLabel.text = "No users saved :("
lastMessageLabel.text = "Tap the search tab to find users."
}
return cell
}
override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
if self.names.count != 0 {
print(self.names.count)
print(self.names[indexPath.row])
print(self.ids[indexPath.row])
self.selectedUserName = self.names[indexPath.row] as! String
self.selectedUserId = self.ids[indexPath.row] as! String
self.selectedUserImage = self.images[indexPath.row]
self.performSegueWithIdentifier("chat", sender: self)
}
}
override func tableView(tableView: UITableView, commitEditingStyle editingStyle: UITableViewCellEditingStyle, forRowAtIndexPath indexPath: NSIndexPath) {
if editingStyle == UITableViewCellEditingStyle.Delete && self.userRef.savedUsers.count != 0 {
startActivityIndicator()
let savedUsers = NSMutableArray()
for user in self.userRef.savedUsers {
if user as! String != self.userRef.savedUsers[indexPath.row] as! String {
savedUsers.addObject(user as! String)
}
}
self.rootRef.child("users").child((FIRAuth.auth()?.currentUser?.uid)!).child("savedUsers").setValue(savedUsers, withCompletionBlock: { (error: NSError?, FIRDatabaseReference: FIRDatabaseReference) -> Void in
if error == nil {
print("deleted: \(self.userRef.savedUsers[indexPath.row])")
// Remove user
self.userRef.savedUsers.removeObject(self.userRef.savedUsers[indexPath.row])
self.names.removeObjectAtIndex(indexPath.row)
self.images.removeAtIndex(indexPath.row)
self.lastMessage.removeObjectAtIndex(indexPath.row)
self.stopActivityIndicator()
self.loadUsers()
self.displayAlert("Contact Deleted", message: "The user has been removed from your contacts.")
} else {
self.stopActivityIndicator()
self.displayAlert("Delete Failed", message: "Please try again later.")
}
})
}
}
编辑：
问题是imageView.contentMode = UIViewContentMode.ScaleAspectFit，需要.ScaleAspectFill
