我有以下的应用程序，我已经实现了一个滚动视图（图像轮廓上的故事板层次：电子滚动视图不滚动
我已经关闭了自动布局，如严重这里的帖子似乎表明这将创建一个问题
这里是我的.h文件：
#import <UIKit/UIKit.h>
#import <MessageUI/MessageUI.h>
#import <MessageUI/MFMailComposeViewController.h>
#import <AssetsLibrary/ALAsset.h>
#import <AssetsLibrary/ALAssetRepresentation.h>
#import <ImageIO/CGImageSource.h>
#import <ImageIO/CGImageProperties.h>
#import <CoreLocation/CoreLocation.h>
@interface DobInAHoonViewController : UIViewController<UIImagePickerControllerDelegate, UINavigationControllerDelegate, MFMailComposeViewControllerDelegate, UITextFieldDelegate, CLLocationManagerDelegate>
{
IBOutlet UIPickerView *vehiclePickerView;
UIImagePickerController *picker1;
UIImagePickerController *picker2;
UIImage *image;
IBOutlet UIImageView *imageView;
CLLocationManager *locationManager;
CGFloat animatedDistance;
}
@property (strong, nonatomic) IBOutlet UIImageView *BackgroundImage;
@property (strong, nonatomic) IBOutlet UIScrollView *scrollView;
@property (strong, nonatomic) NSString *Latitude;
@property (strong, nonatomic) NSString *longditute;
@property (strong, nonatomic) NSArray *toRecipients;
@property (strong, nonatomic) ALAssetsLibrary *assetsLibrary;
@property (strong, nonatomic) NSMutableArray *groups;
@property (nonatomic, retain) IBOutlet UITextField *vehilceMake;
@property (nonatomic, retain) IBOutlet UITextField *vehilceColour;
@property (nonatomic, retain) IBOutlet UITextField *regoNumber;
@property (nonatomic, retain) IBOutlet UITextField *location;
@property (nonatomic, retain) IBOutlet UITextField *additionalInfo;
@property (nonatomic, retain) IBOutlet UITextField *vehicleType;
- (IBAction)takePhoto;
-(IBAction)chooseExisting;
-(IBAction)actionEmailComposer;
-(IBAction)textFileReturn:(id)sender;
-(IBAction)DismissKeyboard:(id)sender;
@end
和我的.m文件：
#import "DobInAHoonViewController.h"
@interface DobInAHoonViewController()
@end
@implementation DobInAHoonViewController
@synthesize BackgroundImage;
@synthesize vehilceColour;
@synthesize vehilceMake;
@synthesize regoNumber;
@synthesize Latitude;
@synthesize location;
@synthesize longditute;
@synthesize additionalInfo;
@synthesize toRecipients;
@synthesize assetsLibrary;
@synthesize groups;
@synthesize vehicleType;
@synthesize scrollView;
static const CGFloat KEYBOARD_ANIMATION_DURATION = 0.3;
static const CGFloat MINIMUM_SCROLL_FRACTION = 0.2;
static const CGFloat MAXIMUM_SCROLLFRACTION = 0.8;
static const CGFloat PORTRAIT_KEYBOARD_HEIGHT = 216;
static const CGFloat LANDSCAPE_KEYBOARD_HEIGHT = 140;
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
[vehilceMake resignFirstResponder];
[vehilceMake resignFirstResponder];
[vehilceColour resignFirstResponder];
[location resignFirstResponder];
[additionalInfo resignFirstResponder];
[regoNumber resignFirstResponder];
return YES;
}
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
}
return self;
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
[self.scrollView setScrollEnabled:YES];
[self.scrollView setContentSize:(CGSizeMake(320, 1000))];
locationManager = [[CLLocationManager alloc]init];
toRecipients = [[NSArray alloc]initWithObjects:@"[email protected]", nil];
BackgroundImage.alpha = 0.3;
static int emergAlertCounter;
if (emergAlertCounter <1) {
UIAlertView *emergencyAlert = [[UIAlertView alloc]
initWithTitle:@"NOTE" message:@"Do not endanger your life to dob in a hoon. If your life is threatened, or you are reporting an emergency situation, exit this app and dial '000' IMMEDIATLY!" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[emergencyAlert show];
emergAlertCounter = emergAlertCounter+1;
}
}
由于某种原因，当我运行应用程序时，滚动视图不滚动。我已将该属性设置为在界面构建器中滚动。
任何建议将不胜感激。
