设置默认UISegmentedControl

Question

试着设置UISegmentedControl 的界面。

实现代码：

UIImage *segmentSelected = [[UIImage imageNamed:@"Segment_Unselected.png"]
                            resizableImageWithCapInsets:UIEdgeInsetsMake(0, 12, 0, 12)];
UIImage *segmentUnselected = [[UIImage imageNamed:@"Segment_Selected.png"]
                              resizableImageWithCapInsets:UIEdgeInsetsMake(0, 12, 0, 12)];

[[UISegmentedControl appearance] setBackgroundImage:segmentUnselected
                                           forState:UIControlStateNormal
                                         barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setBackgroundImage:segmentSelected
                                           forState:UIControlStateSelected
                                         barMetrics:UIBarMetricsDefault];

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                         [UIColor colorWithRed:77.0/255.0 green:45.0/255.0 blue:8.0/255.0 alpha:1],UITextAttributeTextColor,
                                                         [UIColor clearColor], UITextAttributeTextShadowColor,
                                                         [NSValue valueWithUIOffset:UIOffsetMake(0, 0)], UITextAttributeTextShadowOffset,
                                                         [UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0], UITextAttributeFont, nil] forState:UIControlStateNormal];

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                                         [UIColor whiteColor],UITextAttributeTextColor,
                                                         [UIColor clearColor], UITextAttributeTextShadowColor,
                                                         [NSValue valueWithUIOffset:UIOffsetMake(0, 0)], UITextAttributeTextShadowOffset,
                                                         [UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0], UITextAttributeFont, nil] forState:UIControlStateSelected];

[[UISegmentedControl appearance] setDividerImage:[UIImage imageNamed:@"SegmentedControl_Divider.png"]
                             forLeftSegmentState:UIControlStateNormal
                               rightSegmentState:UIControlStateNormal
                                      barMetrics:UIBarMetricsDefault];

然后显示出的界面很漂亮：

但是我需要的界面是这样的：

应该怎么设置？

将下面这段代码放到设置默认控制器的viewcontroller 中

UIImage *segmentSelected = [[UIImage imageNamed:nil]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 12, 0, 12)];
UIImage *segmentUnselected = [[UIImage imageNamed:nil]resizableImageWithCapInsets:UIEdgeInsetsMake(0, 12, 0, 12)];

[[UISegmentedControl appearance] setBackgroundImage:segmentUnselected
                                 forState:UIControlStateNormal
                                 barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setBackgroundImage:segmentSelected
                                 forState:UIControlStateSelected
                                 barMetrics:UIBarMetricsDefault];

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                [UIColor colorWithRed:77.0/255.0 green:45.0/255.0 blue:8.0/255.0 alpha:1],UITextAttributeTextColor,
                                [UIColor clearColor], UITextAttributeTextShadowColor,
                                [NSValue valueWithUIOffset:UIOffsetMake(0, 0)], UITextAttributeTextShadowOffset,
                                [UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0], UITextAttributeFont, nil] forState:UIControlStateNormal];

[[UISegmentedControl appearance] setTitleTextAttributes:[NSDictionary dictionaryWithObjectsAndKeys:
                                 [UIColor whiteColor],UITextAttributeTextColor,
                                 [UIColor clearColor],UITextAttributeTextShadowColor,      
                                 [NSValue valueWithUIOffset:UIOffsetMake(0, 0)],UITextAttributeTextShadowOffset,
                                 [UIFont fontWithName:@"HelveticaNeue-Bold" size:16.0], UITextAttributeFont, nil] forState:UIControlStateSelected];

[[UISegmentedControl appearance] setDividerImage:[UIImage imageNamed:nil] 
                                 forLeftSegmentState:UIControlStateNormal   
                                 rightSegmentState:UIControlStateNormal 
                                 barMetrics:UIBarMetricsDefault];
