小编Adr*_*lli的帖子

我有一个textView带有数字(变量)和a的内部string,我怎么能给出比这个大一号的string？代码:

TextView size = (TextView)convertView.findViewById(R.id.privarea_list_size);
if (ls.numProducts != null) {
    size.setText(ls.numProducts + " " + mContext.getString(R.string.products));
}

我想ls.numproducts的大小与文本的其余部分不同.怎么做？

在我的AppDelegate中有一个我不明白的问题.RootViewController最初调用了ViewController,我改名了.该应用程序由许多ViewController组成,然后我介绍了一个UINavigationController.为什么会出现此错误？

我必须添加一个UIImageView作为MapView的子视图.为此,我在MapView上创建了一个图层.在这一层,我想放置我的图像,但我得到一个白色的矩形,没有别的.我的图片不可见.

这是代码:

- (void)viewDidLoad
{
    //......

    CALayer *layer = [CALayer layer];
    layer.backgroundColor = [[UIColor whiteColor] CGColor];

    if(UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone)
    {
        layer.bounds = CGRectMake(self.mapView.bounds.origin.x,
                                  self.mapView.bounds.origin.y, 80, 300);
    }
    else
    {
        layer.bounds = CGRectMake(self.mapView.frame.origin.x,
                                  self.mapView.frame.origin.y, 150, 700);
    }

    layer.contents = (id)[UIImage imageNamed:@"myImage.png"];
    //the name is correct but  in the output the image is not visible

    [[self.mapView layer] addSublayer:layer];
    [layer setNeedsDisplay];
}

我有一个包含10个项目的数组.当我IndexOfObject为元素编号9 调用" "时,元素编号10 Xcode返回异常:" NSRangeException"

原因:'_ [_ NSCFArray objectAtIndex:]索引:2147483647超出边界(10)'.

从前一个NSLog,我看到数组中存在两个元素,但indexOfObject没有找到它们.为什么？

我的代码是:

    NSDictionary * headConfig =[avatarDictionaryToSave objectForKey:@"head_dictionary"];
    NSString * headImage =[headConfig objectForKey:@"layer_key"];
    NSString * pathFace =[[NSBundle mainBundle]pathForResource:@"Face" ofType:@"plist"];
    NSLog(@"%@", headImage);

    NSArray *arrayFace =[NSArray arrayWithContentsOfFile:pathFace];
    NSLog(@"the  elements are: %@", arrayFace);//here headImage is present
    int index =[arrayFace indexOfObject:headImage];
    NSLog(@"the index is %d", index);

我在AppDelegate中遇到问题,运行应用程序时出现此错误:

  Terminating app due to uncaught exception 'NSUnknownKeyException', reason:

我的应用程序的RootViewController有问题.当我运行应用程序时,我收到此错误.这意味着什么？

我有一个DialogFragment 带有FrameLayout容器的自定义,我想放一个容器,Fragment但它的视图总是返回null,我该怎么办？

在 DialogCreateAccount.java

   public class DialogCreateAccount extends DialogGeneral implements OnClickListener{

   @Override
   public Dialog onCreateDialog(Bundle savedInstanceState) {
    // TODO Auto-generated method stub

    Dialog dialog = super.onCreateDialog(savedInstanceState);

    //........


    return dialog;

   }


@Override
public void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);

     Fragment fragment = CreateAccountFragment.newInstance();


     FragmentTransaction ft = getFragmentManager().beginTransaction();

         if(fragment.getView()!=null){ // return always null

            ft.add(
                    getFrameContainer().getId(),
                    fragment
                    )
            .commit();
         }else{

         }

        Log.i("DialogCreateAccount", "fragment:" +fragment.getView());// return null
  }

我有一个scrollView具有UIView作为子视图.这有UIView子视图a UIButton.只有scrollView连接到插座,其余全部都是代码.按钮不响应触摸,触摸时不变蓝.我能做些什么才能让它发挥作用？

这是代码:

   - (void)viewDidLoad
 {
       [super viewDidLoad];

      //......

      self.buttonHome = [UIButton buttonWithType:UIButtonTypeCustom];
      [self.buttonHome addTarget:self action:@selector(pressedHome:)
                                  forControlEvents:UIControlEventTouchUpInside];
      //....
      self.containerView =[[UIView alloc]initWithFrame:self.scrollView.frame];
      self.containerView.userInteractionEnabled=YES;

      [self.scrollView addSubview:self.containerView];
      [self.containerView addSubview:self.buttonHome];
  }

  -(void) pressedHome:(id)sender{
         //....
  }

我有一个ViewControllerA和一个ViewControllerB.我想从ViewControllerB调用ViewControllerA的方法.

在ViewControllerA中有一个方法:

  -(NSMutableArray*) loadData;

在ViewControllerB.h中:

 #import "ViewControllerA.h"
  .......
 @property (nonatomic, strong) ViewControllerA * viewControllerA;
 @property (nonatomic, strong) NSMutableArray * mutableArray;

在ViewControllerB.m中:

self.mutableArray =[viewControllerA loadData];

但方法不是调用.为什么？提前致谢

当我在NetBeans中打开main.xml文件时,我无法看到Eclipse中发生的图形布局.我该怎么做才能搞定？我要安装一些东西？提前致谢

当我运行我的应用程序时,我收到此错误:

    Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-
     [UIRoundedRectButton copyWithZone:]: unrecognized selector sent to instance
     0xcc86970'

为什么我会收到这样的错误？我小心翼翼地检查IBOutlets的所有连接e所有IBAction.这是我的代码:

MenuViewController.h

     @interface MenuViewController : UIViewController
<UITableViewDelegate, UITableViewDataSource>{

}


@property (nonatomic, copy) IBOutlet UITableView * tableView;
@property (nonatomic,copy) IBOutlet UILabel *labelTitle;
@property (nonatomic, copy) IBOutlet UIButton *buttonHome;
@property (nonatomic, copy) IBOutlet UIButton *buttonMap;
@property (nonatomic, copy) IBOutlet UIButton *buttonFavorites;

 -(IBAction) pressedHome:(id)sender;
-(IBAction) pressedMap: (id)sender;
-(IBAction) pressedFavorites: (id)sender;

 @end

在MenuViewController.m中

 -(IBAction) pressedHome:(id)sender{

     MenuViewController * menu =[[MenuViewController alloc]initWithNibName:@"MenuViewController" bundle:nil];
   [self.navigationController pushViewController:menu animated:YES];


    }

  -(IBAction) …

我通过屏幕上设置的UITapGestureRecognizer获得了x和y,在获得了我找到对象触摸的位置后,所以我把条件,但不起作用.也许我把错误的条件放在目标C中？Xcode没有错误,但功能不起作用.

  -(void)tappedMapOniPad:(int)x andy:(int)y{
       NSLog(@"the x is: %d", x);
         //the x is: 302
       NSLog(@"the y is: %d", y);
         //the y is: 37

       if((121<x<=181) && (8<y<=51)){ //the error is here
            self.stand = 431;
        }else if ((181<x<=257) && (8<y<=51)){
            self.stand=430;
        }else if ((257<x<=330) && (8<y<=51)){
            self.stand = 429;
        }

      NSLog(@"The stand is %d", self.stand);
        //The stand is 431

   }

我能怎么做？
