的子類不顯示我有，我想展現一個UIImageView和幾個UILabels自定義視圖（UIView的子類）。 imageView與FaceBook異步傳遞，標籤從特定方法獲取文本。問題在於，即使imageView在到達時呈現成功，標籤也不會顯示。 讓我告訴你的代碼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;
和實現如下：
@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;
}
請注意，標籤矩形硬編碼爲方便和不匹配。 用於設置標籤文本的方法的樣品如下：
- (void)showLbl1:(NSString *)str withFont:(UIFont *)font andColor:(UIColor *)color
{
self.lbl1.font = font;
self.lbl1.textColor = [UIColor cyanColor];
[self.lbl1 setText:str];
}
的圖像與由performSelectorInBackground運行，並與通過performSelectorOnMainThread運行的方法繪製的方法遞送。 最後，整個視圖由addSubView在上海華加入。
Thanx提前
添加標籤爲視圖像這樣子視圖[self.view addSubview：self.lbl4]。 – Prajan
是否showLbl1和這樣的方法被調用？ – Madhu
