.plist에서 채워지는 UIPicker를 작성했습니다. 이 부분은 잘 작동합니다. 행이 선택되면 기본 UI가 다른 UIView에 표시됩니다.UIPicker 및 선택한 행 데이터를 UIView로 보냅니다.
내하는 .m 파일의 코드는 다음과 같습니다
#import "airlinePickerViewController.h"
@implementation airlinePickerViewController
@synthesize picker;
@synthesize airlines;
@synthesize airline;
@synthesize teleno;
- (IBAction)butonPressed:(id)sender
{
NSInteger airRow = [picker selectedRowInComponent:kAirlineComponent];
NSInteger telRow = [picker selectedRowInComponent:kTelenoComponent];
NSString *air = [self.airline objectAtIndex:airRow];
NSString *tel = [self.teleno objectAtIndex:telRow];
NSString *title = [[NSString alloc] initWithFormat:@"You selected %@.", tel];
NSString *message = [[NSString alloc] initWithFormat:@"%@ is in %@", tel, air];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:message delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
[title release];
[message release];
}
