将所选值放入文本字段中
当用户在 pickerView 中选择一个项目并按“确定”按钮时，我必须将所选项目放入 UITextField 中，那么在“确定”按钮的 IBAction 中我应该放置什么？提前谢谢:) 这是我的“确定”按钮代码：
-(IBAction)okButton{
[billTotal setText:@"Hi"];//the text field name is billTotal, this didn't work :(
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
CGAffineTransform transform = CGAffineTransformMakeTranslation(0, 480);
pickerView.transform = transform;
[UIView commitAnimations];
}
when the user select an item in a pickerView and press OK button, i have to put the selected item in a UITextField, so in the IBAction of the OK button what should i put please ? thx in advance :)
this is my OK button code :
-(IBAction)okButton{
[billTotal setText:@"Hi"];//the text field name is billTotal, this didn't work :(
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
CGAffineTransform transform = CGAffineTransformMakeTranslation(0, 480);
pickerView.transform = transform;
[UIView commitAnimations];
}
