我有一个应用程序,在xcode 4.5和ios 6.1滚动时工作得很好.但是,在下载xcode 5和iOS 7后,我的滚动视图不再起作用了.???

这是我的.h文件:

#import <UIKit/UIKit.h>

@interface GrillretterViewController : UIViewController
@property (strong, nonatomic) IBOutlet UIScrollView *grillretterScroller;
@property (assign) CGPoint rememberContentOffset;

@end

这是我的.m文件:

#import "GrillretterViewController.h"

@interface GrillretterViewController ()

@end

@implementation GrillretterViewController
@synthesize grillretterScroller, rememberContentOffset;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    [grillretterScroller setScrollEnabled:YES];

    // Do any additional setup after loading the view.
}

- (void) viewDidAppear:(BOOL)animated {
    [grillretterScroller setContentSize:CGSizeMake(300, 915)]; …
