Ako umiestniť UIPickerView programovo do subView s použitím rozhrania Interface Builder?

odpovede:

Hey! U môže UIPickerView programovo ...

In-viewController.m súbor

- (void)viewDidLoad {
[super viewDidLoad];
UIPickerView *pickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0,100,320, 500)];
[self.view addSubview:pickerView];
[pickerView setDelegate:self];
[pickerView release];
}

- (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)thePickerView {

return ; //give components here
}

- (NSInteger)pickerView:(UIPickerView *)thePickerView numberOfRowsInComponent:(NSInteger)component {

return ;   //give rows here
}

- (NSString *)pickerView:(UIPickerView *)thePickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {   return ;  // give titles }

- (void)pickerView:(UIPickerView *)thePickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {
//Do the step here
}

A vo vašej triede viewController.h to nikdy nezabudlo

@interface viewController : UIViewController <UIPickerViewDelegate>
