如何设置默认的UISegmentedControl外观？

Question

我使用以下代码

设置了UISegmentedControl的外观

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];

我得到了完美的输出

但现在我想设置 UISegment 的默认外观

所以我要做什么???

Answer 1

将此代码放在您想要的默认控制器

的视图控制器上

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];

Answer 2

在上面的代码上将imagename设置为nil，并将其放在您想要默认行为的视图

上

Answer 3

删除已分配图像的代码。

Answer 4

将段控制器的图像设置为nil。然后，一旦清理你的模拟器然后运行。会没事的......
