当用户在pickerView中选择一个项目并按下OK按钮时,我必须将所选项目放在UITextField中,所以在OK按钮的IBAction中我该放什么? thx提前:) 这是我的OK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];
}
答案 0 :(得分:1)
这样的事情:
...
NSInteger selectedRow = [picker selectedRowInComponent:0];
billTotal.text = [NSString stringWithFormat:@"%d", selectedRow];
...
这不起作用
检查您的插座是否连接到文本字段,并且调用“okButton”选择器
