ios中键盘处理（二）

设置UIscrollview的背景代码

- (UIImage *) ImageWithColor: (UIColor *) color frame:(CGRect)aFrame
{
    UIGraphicsBeginImageContext(aFrame.size);
    CGContextRef context = UIGraphicsGetCurrentContext();
    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, aFrame);
    
    UIImage *theImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return theImage;
}

   UIImage *image=[self ImageWithColor:[UIColor colorWithRed:240/255.0f green:240/255.0f blue:240/255.0f alpha:1] frame:self.view.bounds];
    
   image= [image stretchableImageWithLeftCapWidth:image.size.width*0.5f topCapHeight:image.size.height*0.5f];
    UIImageView *imageview=[[UIImageView alloc] initWithImage:image];
    [scrollview addSubview:imageview];

动态生成控件

//封装UILabel
+(UILabel*)LabWithFrame:(CGRect)_rect 
                   text:(NSString*)aText 
              textColor:(UIColor*)aColor 
              textAlign:(NSTextAlignment)aAlign 
                   font:(UIFont*)aFont{
    UILabel *lab = [[[UILabel alloc] initWithFrame:_rect] autorelease];
    lab.backgroundColor = [UIColor clearColor];
    if ([aText length] > 0) 
        lab.text = aText;
    if (aColor)
        lab.textColor = aColor;
    if(aAlign)
        lab.textAlignment = aAlign;
    if (aFont)
        lab.font = aFont;
    return lab;
}
//文本框

+(UITextField*)TextFieldWithFrame:(CGRect)_rect
                           target:(id)target
                             text:(NSString*)aText
                        textColor:(UIColor*)aTextColor
                        textAlign:(NSTextAlignment)aAlign
                      placeHolder:(NSString*)holder
                        clearMode:(UITextFieldViewMode)aViewMode
{
    UITextField *textField = [[[UITextField alloc] initWithFrame:_rect] autorelease];
    textField.backgroundColor = [UIColor clearColor];
    textField.delegate = target;
    
    if (aAlign)
        textField.textAlignment = aAlign;
    if ([aText length] > 0)
        textField.text = aText;
    if (aTextColor)
        textField.textColor = aTextColor;
    if (aViewMode)
        textField.clearButtonMode = aViewMode;
    if ([holder length] > 0)
        textField.placeholder = holder;
    textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
    
    return textField;
}

   
    CGRect viewRect=self.view.bounds;
    CGRect bRec,ftRec=self.view.bounds;
    ftRec=UIEdgeInsetsInsetRect(viewRect, UIEdgeInsetsMake(Kpadding, Kpadding, Kpadding, Kpadding));
    
    for (int i=0; i<self.mydata.count; i++) {
        
        Person *p=self.mydata[i];
        //得到每一行 ，每行50的距离分割
        CGRectDivide(ftRec, &bRec, &ftRec, 50, CGRectMinYEdge);
        
     //得到padding的巨鹿
        CGRect lbRect=UIEdgeInsetsInsetRect(bRec, UIEdgeInsetsMake(0, 0, 0, kLbWidth));

        //得到label的值
        UILabel *label=[UILabel LabWithFrame:lbRect text:p.name textColor:[UIColor blackColor] textAlign:NSTextAlignmentRight font:[UIFont systemFontOfSize:12]];
        [self.view addSubview:label];
        [label release];
        
        CGRect txtRect=UIEdgeInsetsInsetRect(bRec, UIEdgeInsetsMake(Kpadding, lbRect.size.width+Kpadding, 0, 0));

        UITextField *txtField=[UITextField TextFieldWithFrame:txtRect target:self text:p.desc textColor:[UIColor blackColor] textAlign:NSTextAlignmentLeft placeHolder:nil clearMode: UITextFieldViewModeWhileEditing];
        txtField.borderStyle=UITextBorderStyleRoundedRect;
        [self.view addSubview:txtField];
        [txtField release];
    }

TableView背景设置

UIImageView *tableBg = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"XXX.png"]];
[yourTable setBackgroundView:tableBg];
[tableBg release];
