cellforRowAtIndexPath中的條件代碼：無法正常工作

Question

我在cellForRowAtIndexPath：方法中有一些條件代碼。它似乎是在iOS6的，但在隨後的iOS 7工作正常細胞按鈕有三個點鼠標懸停在...

它似乎也像他們可能在其他的每一個都可以添加一個按鈕if語句的條件得到滿足。

我有下面的代碼後，如果(cell == nil) { } ，因爲我需要檢查值類別ID爲每個表格單元格行

的NSNumber * CATID = [[self.listingNodesArray objectAtIndex條件代碼：indexPath.row ] objectForKey：@「category_id」];

if ([catId isEqualToNumber:[NSNumber numberWithInt:9]] && (a == 0)) { 
    cell.cornerImageView.image = [UIImage imageNamed:@"cellComprareCorner.png"]; 

    [cell.salvaBtn setBackgroundImage:[UIImage imageNamed:@"home_verde_commentsOFF.png"] 
          forState:UIControlStateNormal]; 
} 


else if ([catId isEqualToNumber:[NSNumber numberWithInt:9]] && (a != 0)) { 
     cell.cornerImageView.image = [UIImage imageNamed:@"cellComprareCorner.png"]; 

     [cell.salvaBtn setBackgroundImage:[UIImage imageNamed:@"home_verde_commentsON.png"] 
           forState:UIControlStateNormal]; 
} 



if ([catId isEqualToNumber:[NSNumber numberWithInt:9]] && (b == 0)) { 

    [cell.likeBtn setBackgroundImage:[UIImage imageNamed:@"home_verde_likeOFF.png"] 
           forState:UIControlStateNormal]; 
} 


else if ([catId isEqualToNumber:[NSNumber numberWithInt:9]] && (b != 0)) { 

    [cell.likeBtn setBackgroundImage:[UIImage imageNamed:@"home_verde_likeON.png"] 
           forState:UIControlStateNormal]; 
} 



if ([catId isEqualToNumber:[NSNumber numberWithInt:10]] && (a == 0)) { 
      cell.cornerImageView.image = [UIImage imageNamed:@"cellBlueCorner.png"]; 

      [cell.salvaBtn setBackgroundImage:[UIImage imageNamed:@"home_blu_commentsOFF.png"] 
            forState:UIControlStateNormal]; 
     } 


     else if ([catId isEqualToNumber:[NSNumber numberWithInt:10]] && (a != 0)) { 
      cell.cornerImageView.image = [UIImage imageNamed:@"cellComprareCorner.png"]; 

      [cell.salvaBtn setBackgroundImage:[UIImage imageNamed:@"home_blu_commentsON.png"] 
            forState:UIControlStateNormal]; 
     } 



     if ([catId isEqualToNumber:[NSNumber numberWithInt:10]] && (b == 0)) { 

      [cell.likeBtn setBackgroundImage:[UIImage imageNamed:@"home_blu_likeOFF.png"] 
            forState:UIControlStateNormal]; 
     } 


     else if ([catId isEqualToNumber:[NSNumber numberWithInt:10]] && (b != 0)) { 

      [cell.likeBtn setBackgroundImage:[UIImage imageNamed:@"home_blu_likeON.png"] 
            forState:UIControlStateNormal]; 
     } 

Answer 1

請確保您的按鈕標題從XIB文件中刪除。它爲我工作。

Answer 2

您必須刪除XIB文件中的按鈕標題文本。

這三個點出現是因爲按鈕標題文本大於按鈕大小，所以省略號出現。
