在我的代码中：
@IBOutlet weak var textField: UITextField!
@IBAction func textField(sender: AnyObject) {
if textField.text != "" {
let newSweet = CKRecord(recordType: "Chat")
newSweet["content"] = textField.text
textField.delegate = self
let publicData = CKContainer.defaultContainer().publicCloudDatabase
publicData.saveRecord(newSweet,completionHandler: { (record:CKRecord?,error:NSError?) -> Void in
if error == nil {
dispatch_async(dispatch_get_main_queue(),{ () -> Void in
self.tableView.beginUpdates()
self.sweets.insert(newSweet,atIndex: 0)
let indexPath = NSIndexPath(forRow: 0,inSection: 0)
self.tableView.insertRowsAtIndexPaths([indexPath],withRowAnimation:
.Top)
func textFieldShouldReturn(textField: UITextField) -> Bool {
self.textField.resignFirstResponder()
return true
}})
}else{
print(error)
}
})
}
}
我正在尝试访问cloudKit,因此当您在UITextField中键入内容时,它会激活UITextField @IBAction.
现在当我在UITextField中输入文本时没有任何反应,所以我需要它来激活@IBAction.有没有人有办法解决吗？
解决方法
在ViewController中,导入协议UITextFieldDelegate,如下所示：
class YourViewController: UIViewController,UITextFieldDelegate
在你的viewDidLoad中这样做：
override func viewDidLoad() {
super.viewDidLoad()
textField.delegate = self
}
你必须安装委托方法：
func textFieldDidBeginEditing(textField: UITextField!) {
let newSweet = CKRecord(recordType: "Chat")
newSweet["content"] = textField.text
textField.delegate = self
let publicData = CKContainer.defaultContainer().publicCloudDatabase
publicData.saveRecord(newSweet,withRowAnimation:
.Top)
func textFieldShouldReturn(textField: UITextField) -> Bool {
self.textField.resignFirstResponder()
return true
}})
}
如果要单击键盘上的Return键将关闭键盘,则必须安装此TextFieldDelegate方法
func textFieldShouldReturn(textField: UITextField) -> Bool {
self.textField.resignFirstResponder()
return true
}
