錯誤設置集合中的文本查看單元格

Question

當我nslog值設置它爲NULL後，任何字爲什麼？

CustomCollectionVIewCell *cell =[[CustomCollectionVIewCell alloc]init]; 
NSString *name =[dict valueForKey:@"filterName"];//works 
[cell.labelDisplay setText:name];//does not 
NSLog(@"name = %@",cell.labelDisplay.text); 
cell.isSelected=NO; 
[_availableHealthFilters setObject:cell atIndexedSubscript:i];

在自定義單元格中初始化您的labelDisplay。

//customColectionCell.h 
@property(strong,nonomatic) NSString *labelText; 
-(void)setCellLabelText:(NSString *)labelText; 
//customCollectionCell.m 
-(id)init{ 
//init cellLabel and addSubView to customCell 

} 
//Than set label in custom method 
-(void)setCellLabelText:(NSString *)labelText{ 
_labelText = labelText; 
sefl.labelDisplay.text = labelText; 
}
