的子类不显示我有，我想展现一个UIImageView和几个UILabels自定义视图（UIView的子类）。 imageView与FaceBook异步传递，标签从特定方法获取文本。问题在于，即使imageView在到达时呈现成功，标签也不会显示。 让我告诉你的代码UILabels中的UIView
@interface CustomView : UIView {
UIImageView *imageView;
UILabel *lbl1;
UILabel *lbl2;
UILabel *lbl3;
UILabel *lbl4;
}
@property(nonatomic,retain) UIImageView *imageView;
@property(nonatomic,retain) UILabel *lbl1;
@property(nonatomic,retain) UILabel *lbl2;
@property(nonatomic,retain) UILabel *lbl3;
@property(nonatomic,retain) UILabel *lbl4;
和实现如下：
@implementation CustomView
@synthesize imageView;
@synthesize lbl1;
@synthesize lbl2;
@synthesize lbl3;
@synthesize lbl4;
- (id)initWithFrame:(CGRect)frame
{
if ((self = [super initWithFrame:frame]))
{
self.lbl1 = [[UILabel alloc] initWithFrame:CGRectMake(65, 356, 98, 13)];
self.lbl1.backgroundColor = [UIColor clearColor];
[self addSubview:self.lbl1];
self.lbl2 = [[UILabel alloc] initWithFrame:CGRectMake(260, 356, 50, 13)];
self.lbl2.backgroundColor = [UIColor clearColor];
[self addSubview:self.lbl2];
self.lbl3 = [[UILabel alloc] initWithFrame:CGRectMake(65, 374, 92, 13)];
self.lbl3.backgroundColor = [UIColor clearColor];
[self addSubview:self.lbl3];
self.lbl4 = [[UILabel alloc] initWithFrame:CGRectMake(260, 374, 49, 13)];
self.lbl4.backgroundColor = [UIColor clearColor];
[self addSubview:self.lbl4];
}
return self;
}
请注意，标签矩形硬编码为方便和不匹配。 用于设置标签文本的方法的样品如下：
- (void)showLbl1:(NSString *)str withFont:(UIFont *)font andColor:(UIColor *)color
{
self.lbl1.font = font;
self.lbl1.textColor = [UIColor cyanColor];
[self.lbl1 setText:str];
}
的图像与由performSelectorInBackground运行，并与通过performSelectorOnMainThread运行的方法绘制的方法递送。 最后，整个视图由addSubView在上海华加入。
Thanx提前
添加标签为视图像这样子视图[self.view addSubview：self.lbl4]。 – Prajan
是否showLbl1和这样的方法被调用？ – Madhu
@ozzotto：如果有任何疑问，你能帮我吗？ – Prajan
