전화 번호로 4 UIButtons 설정 Xcode

Question

사용자가 배경 그림을 변경할 수 있도록 4 개의 UIButton이있는 처음 4 개의 ImageView가 있습니다. 그건 완벽하게 작동합니다. 그렇지만 ImageViews에 4 개의 UIButton이 있는데 전화 번호를 불러야합니다. 내가 그것을 실행할 때 그것을 클릭하면 아무것도 일어나지 않기 때문에 그것은 버튼을 호출하는 것 같다. 여기 내 코드는 다음과 같습니다.

#import "ViewController.h" 

@interface ViewController() 
{ 
UIImagePickerController *imagePickerController; 
UIImagePickerController *imagePickerController2; 
UIImagePickerController *imagePickerController3; 
UIImagePickerController *imagePickerController4; 
} 

@end 

@implementation ViewController 
@synthesize firstImageView, secondImageView, thirdImageView, fourthImageView; 
- (void)viewDidLoad 
{ 
[super viewDidLoad]; 

} 

- (void)didReceiveMemoryWarning 
{ 
[super didReceiveMemoryWarning]; 

} 

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info 
{ 
UIImage *image1 = [info objectForKey:UIImagePickerControllerOriginalImage]; 

NSData *data = UIImagePNGRepresentation(image1); 
NSString *myGrabbedImage = @"myGrabbedImage.png"; 
NSArray *path = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentDirectory = [path objectAtIndex:0]; 
NSString *fullPathToFile = [documentDirectory stringByAppendingPathComponent:myGrabbedImage]; 

[data writeToFile:fullPathToFile atomically:YES]; 

if (picker == imagePickerController) { 
    [[self firstImageView]setImage:image1]; 
} else if (picker == imagePickerController2) { 
    [[self secondImageView]setImage:image1]; 
} else if (picker == imagePickerController3) { 
    [[self thirdImageView]setImage:image1]; 
} else { 
    [[self fourthImageView]setImage:image1]; 
} 

[self dismissViewControllerAnimated:YES completion:nil]; 

} 

- (IBAction)firstChangeButton:(id)sender 
{ 
imagePickerController = [[UIImagePickerController alloc]init]; 
[imagePickerController setDelegate:self]; 
[imagePickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
[self presentViewController:imagePickerController animated:YES completion:nil]; 

} 
- (IBAction)secondChangeButton:(id)sender 
{ 
imagePickerController2 = [[UIImagePickerController alloc]init]; 
[imagePickerController2 setDelegate:self]; 
[imagePickerController2 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
[self presentViewController:imagePickerController2 animated:YES completion:nil]; 

} 
- (IBAction)thirdChangeButton:(id)sender 
{ 
imagePickerController3 = [[UIImagePickerController alloc]init]; 
[imagePickerController3 setDelegate:self]; 
[imagePickerController3 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
[self presentViewController:imagePickerController3 animated:YES completion:nil]; 

} 
- (IBAction)fourthChangeButton:(id)sender 
{ 
imagePickerController4 = [[UIImagePickerController alloc]init]; 
[imagePickerController4 setDelegate:self]; 
[imagePickerController4 setSourceType:UIImagePickerControllerSourceTypePhotoLibrary]; 
[self presentViewController:imagePickerController4 animated:YES completion:nil]; 

} 



- (IBAction)callFirst:(id)sender 
{ 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:0739421700"]]; 
} 

- (IBAction)callSecond:(id)sender 
{ 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:073942100"]]; 
} 

- (IBAction)callThird:(id)sender 
{ 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:0739421700"]]; 
} 

- (IBAction)callFourth:(id)sender 
{ 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel:0739421700"]]; 

} 
@end 

뭐가 잘못 되었나요?

iOS 시뮬레이터에서 테스트 중이라고 가정합니다. 작동하지 않습니다. 이 코드는 실제 iOS 기기에서만 작동합니다.
