不兼容的指針使用'UITextField *'類型的表達式初始化'NSString *'類型

Question

我的應用程序出現問題。目前，我試圖將數據壓入我的PHP腳本。但是，當我按下按鈕時，整個App凍結。這是我的代碼。

Answer 1

變化：

NSString *name = self.NameText; 
NSString *invite = self.InviteText; 
NSString *email = self.EmailText; 
NSString *phone = self.CellText; 
NSString *date = self.DateText; 

到：

NSString *name = self.NameText.text; 
NSString *invite = self.InviteText.text; 
NSString *email = self.EmailText.text; 
NSString *phone = self.CellText.text; 
NSString *date = self.DateText.text;

您需要訪問您的UITextField性能

NSString *name = self.NameText.text; 
NSString *invite = self.InviteText.text; 
NSString *email = self.EmailText.text; 
NSString *phone = self.CellText.text; 
NSString *date = self.DateText.text;
