UITextField提示在iPhone上使用C＃

Question

我想在我的iPhone应用程序的UITextField中放置临时文本。 Android有提示属性在文本字段中显示临时文本。我如何在iPhone开发中做同样的事情？

Answer 1

UITextFields有让您设置的提示文本占位符属性：

MyTextField.Placeholder = "Required"; 

Answer 2

有二手占位为UITextField不同的方法如下

CGRect frame = CGRectMake(0, 0, 160, 29); 
UITextField *search= [[UITextField alloc] initWithFrame:frame]; 
search.borderStyle = UITextBorderStyleRoundedRect; 
search.textColor = [UIColor blackColor]; 
search.font = [UIFont systemFontOfSize:17.0]; 
search.placeholder = @"Suchen"; 
search.backgroundColor = [UIColor clearColor]; 
search.autocorrectionType = UITextAutocorrectionTypeNo; 
search.keyboardType = UIKeyboardTypeDefault; 
search.returnKeyType = UIReturnKeySearch; 
search.clearButtonMode = UITextFieldViewModeWhileEditing; 
search.delegate = self;
