爲什麼其中一個段在分段控制上顯示爲禁用？

Question

我有一個分段控件與自定義圖像的細分市場。我有如下

[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOffState"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOnState"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault]; 


[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"on_div"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"off_div"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 

CGRect frameSeg= repaymetSegmentedControl.frame; 
[repaymetSegmentedControl setFrame:CGRectMake(frameSeg.origin.x, frameSeg.origin.y-5, frameSeg.size.width, frameSeg.size.height + 15)]; 

在這裏，當我跑我選擇基於偏好段中的一個應用程序創建它。它顯示如圖所示。不知道它有什麼問題。是

在viewDidLoad中使用此代碼給了我認爲您正在尋找的結果（我重命名了您的圖像以使事情對我更清晰）。

[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"whiteBG"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControll setBackgroundImage:[UIImage imageNamed:@"pinkBG"] forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"pinkBG"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControl setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor blackColor]} forState:UIControlStateNormal ]; 
    [repaymetSegmentedControll setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]} forState:UIControlStateHighlighted ]; 
    [repaymetSegmentedControl setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]} forState:UIControlStateSelected ]; 

    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateHighlighted rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault]; 
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"whiteDivider"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 

使用此代碼，結果是這樣的。附圖片：

我的猜測是，所選段的文本顏色設置爲黑色和白色。所以在你的屏幕截圖中選擇了中間段。

這個問題可能是別的地方：

[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOffState"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOnState"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault]; 

這似乎不可思議有圖像名稱以-。

[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"on_div"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 
[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"off_div"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault]; 

你似乎缺少右選擇/左正常選項。

此外，由於你的設計看起來很平坦，我不確定你需要這些。

最後可以將所有圖像附加到問題上嗎？

你的段分隔形象應該是相同的高度的背景圖片。
