如何改變字體顏色真棒上UINavigation酒吧目標C

Question

我新的iOS.And我面對關於改變字體真棒label.My代碼顏色的一個問題是這樣的

UILabel *lab =[[UILabel alloc] init]; 
    lab.text = [NSString awesomeIcon:FaChild]; 

    UIImage *listImage2 = [UIImage imageNamed:@"Image.png"]; 
    UIButton *listButton2 = [UIButton buttonWithType:UIButtonTypeCustom]; 
    listButton2.backgroundColor=[UIColor whiteColor]; 
    [[listButton2 layer] setBorderWidth:0.5f]; 
    listButton2.layer.borderColor =[[UIColor blackColor] CGColor]; 
    listButton2.layer.cornerRadius = calenderbtn.bounds.size.width/3.4;// this value vary as per your desire 
    listButton2.clipsToBounds = YES; 

    UIFont *font = [UIFont fontWithName:@"FontAwesome" size:15.0]; 
    UIColor *color = [UIColor whiteColor]; 

    NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:font 
                   forKey:NSFontAttributeName]; 
    [NSDictionary dictionaryWithObjectsAndKeys:font,NSFontAttributeName,color,NSForegroundColorAttributeName, nil]; 

    NSAttributedString *attributedStr = [[NSAttributedString alloc] initWithString:lab.text attributes:attrsDictionary]; 



    // get the image size and apply it to the button frame 
    CGRect listButton2Frame = listButton2.frame; 
    listButton2Frame.size = listImage2.size; 
    listButton2.frame = listButton2Frame; 

    [listButton2 setAttributedTitle:attributedStr forState:UIControlStateNormal]; 
    [listButton2 addTarget:self 
        action:@selector(LogoutClick:) 
      forControlEvents:UIControlEventTouchUpInside]; 
    UIBarButtonItem *jobsButton2 = 
    [[UIBarButtonItem alloc] initWithCustomView:listButton2]; 

它的輸出看起來像這樣 但它在背面顏色，但我寫白色colour.How代碼改變它的顏色。感謝Advace！

Answer 1

將attrsDictionary分配給第二個NSDictionary，而不是第一個。

NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObjectsAndKeys:font,NSFontAttributeName,color,NSForegroundColorAttributeName, nil]; 

或

// using literals 

NSDictionary *attrsDictionary = @{NSFontAttributeName:font,NSForegroundColorAttributeName:color}; // 

你只設置標籤的字體屬性與第一NSDictionary。
