推荐答案
-(void) viewDidLoad
{
arrayNo = [[NSMutableArray alloc] init];
[arrayNo addObject:@"1"];
[arrayNo addObject:@"2"];
[arrayNo addObject:@"3"];
// and so on....
}
将此行的目标添加到ur文本字段功能
Add target of this line to ur textfield function
UITextfield *entered2;
//..... some codes
[entered2 addTarget:self action:@selector(showPicker)forControlEvents:UIControlEventEditingDidBegin];
[myview addSubview:entered2];
-(void) showPicker
{
[entered2 resignFirstResponder];
pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0,240,220,0)];
pickerView.delegate = self;
pickerView.dataSource = self;
pickerView.showsSelectionIndicator = YES;
[self.view addSubview:pickerView];
[pickerView release];
}
- (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
{
return [arrayNo count];
}
- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView {
return 1;
}
- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component
{
entered2.text=[arrayNo objectAtIndex:row];
[pickerView removeFromSuperview];
}
- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
{
return [arrayNo objectAtIndex:row];
[pickerView removeFromSuperview];
}
- (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component {
int sectionWidth = 300;
