iOS版：的UIView不顯示

我customed一個UIView的iOS版：的UIView不顯示

@implementation PaiLifePageDetail 

@synthesize pageIndex = _pageIndex; 

#define MARGINTOTOP 200.0 
#define MARGINTOLEFT 20.0 
#define WIDTH 120.0 
#define HEIGHT 150.0 


- (id) initWithDataSource : (NSArray *) dataSource 
{ 
self = [super init]; 
if (self) 
{ 
    if (dataSource) 
    { 
     for (PaiLifeCustomImageView *imageView in dataSource) 
     { 
      //page 1 line 1 
      if (_pageIndex == 1) 
      { 
       if ([imageView.location isEqualToString:@"r11"]) 
       { 
        imageView.frame = CGRectMake(MARGINTOLEFT, MARGINTOTOP, WIDTH, HEIGHT * 2); 
        [self addSubview:imageView]; 
       } 
       else if ([imageView.location isEqualToString:@"r12"]) 
       { 
        imageView.frame = CGRectMake(MARGINTOLEFT + WIDTH + 20, MARGINTOTOP, WIDTH, HEIGHT); 
        [self addSubview:imageView]; 
       } 
      } 
      //not page 1 line 1 
      else 
      { 
       if ([imageView.location isEqualToString:@"r11"]) 
       { 
        imageView.frame = CGRectMake(MARGINTOLEFT, MARGINTOTOP, WIDTH, HEIGHT); 
        [self addSubview:imageView]; 
       } 
       else if ([imageView.location isEqualToString:@"r12"]) 
       { 
        imageView.frame = CGRectMake(MARGINTOLEFT + WIDTH + 20, MARGINTOTOP, WIDTH, HEIGHT); 
        [self addSubview:imageView]; 
       } 
       else if ([imageView.location isEqualToString:@"r13"]) 
       { 
        imageView.frame = CGRectMake(MARGINTOLEFT + (WIDTH + 20) * 2, MARGINTOTOP, WIDTH, HEIGHT); 
        [self addSubview:imageView]; 
       } 
      } 

      // line 2 
      if ([imageView.location isEqualToString:@"r21"]) 
      { 
       imageView.frame = CGRectMake(MARGINTOLEFT, MARGINTOTOP + HEIGHT + 20, WIDTH, HEIGHT);

      } 
      else if ([imageView.location isEqualToString:@"r22"]) 
      { 
       imageView.frame = CGRectMake(MARGINTOLEFT + WIDTH + 20, MARGINTOTOP + HEIGHT + 20, WIDTH, HEIGHT); 
       [self addSubview:imageView]; 
      } 
      else if ([imageView.location isEqualToString:@"r23"]) 
      { 
       imageView.frame = CGRectMake(MARGINTOLEFT + (WIDTH + 20) * 2, MARGINTOTOP + HEIGHT + 20, WIDTH, HEIGHT); 
       [self addSubview:imageView]; 
      } 

      // line 3 
      if ([imageView.location isEqualToString:@"r31"]) 
      { 
       imageView.frame = CGRectMake(MARGINTOLEFT, MARGINTOTOP + (HEIGHT + 20) * 2, WIDTH, HEIGHT); 
       [self addSubview:imageView]; 
      } 
      else if ([imageView.location isEqualToString:@"r32"]) 
      { 
       imageView.frame = CGRectMake(MARGINTOLEFT + WIDTH + 20, MARGINTOTOP + (HEIGHT + 20) * 2, WIDTH, HEIGHT); 
       [self addSubview:imageView]; 
      } 
      else if ([imageView.location isEqualToString:@"r33"]) 
      { 
       imageView.frame = CGRectMake(MARGINTOLEFT + (WIDTH + 20) * 2, MARGINTOTOP + (HEIGHT + 20) * 2, WIDTH, HEIGHT); 
       [self addSubview:imageView]; 
      } 

     } 
    } 
} 
[self setNeedsDisplay]; 
return self; 
} 
@end

這是我的看法

implementation PaiLifeViewController 

@synthesize detail = _detail; 

- (void)viewDidLoad 
{ 
[super viewDidLoad]; 
// Do any additional setup after loading the view, typically from a nib. 
UIImage *i = [UIImage imageNamed:@"menu_patcode_normal"]; 
PaiLifeCustomImageView *c1 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c1.location = @"r11"; 
PaiLifeCustomImageView *c2 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c2.location = @"r12"; 
PaiLifeCustomImageView *c4 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c4.location = @"r21"; 
PaiLifeCustomImageView *c5 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c5.location = @"r22"; 
PaiLifeCustomImageView *c6 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c6.location = @"r23"; 
PaiLifeCustomImageView *c7 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c7.location = @"r31"; 
PaiLifeCustomImageView *c8 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c8.location = @"r32"; 
PaiLifeCustomImageView *c9 = [[PaiLifeCustomImageView alloc] initWithImage:i]; 
c9.location = @"r33"; 

NSArray *c = [[NSArray alloc] initWithObjects:c1,c2,c4,c5,c6,c7,c8,c9, nil]; 

//PaiLifePageDetail *pagec 
_detail.pageIndex = 1; 
_detail= [[PaiLifePageDetail alloc] initWithDataSource:c]; 
[_detail awakeFromNib]; 
} 
@end

但它不顯示，我不知道爲什麼，幫助我。謝謝。

看來你從來沒有您的視圖添加到您的視圖控制器，你呢？ – Matthias 2013-02-25 12:35:04

@Matthias我在IB中將我的視圖添加到我的視圖控制器。 – jxdwinter 2013-02-25 12:55:45

那麼，根據你的代碼，你的'detail'對象是在'viewDidLoad'中創建的，也就是爲了延遲NIB自動化。如果你想從NIB加載一個自定義視圖，你必須重寫'initWithCoder：'，c.f. [Apple's guide]（http://developer.apple.com/library/ios/documentation/windowsviews/conceptual/viewpg_iphoneos/CreatingViews/CreatingViews.html#//apple_ref/doc/uid/TP40009503-CH5-SW23）。 – Matthias 2013-02-25 13:19:07

[self.view addSubview:_detail];

在視圖 - 控制

viewDidLoad中
