那里。 我使用自定义背景图像自定义UISegmentedControl。 代码是这样的:
UIImage *segmentSelected = [[UIImage imageNamed:@"segcontrol_sel.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)];
UIImage *segmentUnselected = [[UIImage imageNamed:@"segcontrol_uns.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 10, 0, 10)];
UIImage *segmentSelectedUnselected = [[UIImage imageNamed:@"segcontrol_sel-uns.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
UIImage *segUnselectedSelected = [[UIImage imageNamed:@"segcontrol_uns-sel.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
UIImage *segmentUnselectedUnselected = [[UIImage imageNamed:@"segcontrol_uns-uns.png"] resizableImageWithCapInsets:UIEdgeInsetsMake(0, 5, 0, 5)];
[[UISegmentedControl appearance] setBackgroundImage:segmentUnselected
forState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setBackgroundImage:segmentSelected
forState:UIControlStateSelected
barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setDividerImage:segmentUnselectedUnselected
forLeftSegmentState:UIControlStateNormal
rightSegmentState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setDividerImage:segmentSelectedUnselected
forLeftSegmentState:UIControlStateSelected
rightSegmentState:UIControlStateNormal
barMetrics:UIBarMetricsDefault];
[[UISegmentedControl appearance] setDividerImage:segUnselectedSelected
forLeftSegmentState:UIControlStateNormal
rightSegmentState:UIControlStateSelected
barMetrics:UIBarMetricsDefault];
但结果并非如此。我不太确定该方法的用法:resizableImageWithCapInsets。 图像附加。
应该是这样的:
但实际上它是这样的:
我是guest,我使用了错误的UIEdgeInset值。 背景图片的宽度为:22;身高:30 并且分频器图像的宽度为:11;身高:30 有什么建议吗? 非常感谢提前。

试试这个
仅使用这两个文件及其选中和取消选择的图像
HMSegmentedControl.h
HMSegmentedControl.m
.h文件
#import "HMSegmentedControl.h"
HMSegmentedControl *segmentedControl;
.m文件
viewDidLoad的代码
segmentedControl = [[HMSegmentedControl alloc] initWithSectionImages:@[[UIImage imageNamed:@"1"], [UIImage imageNamed:@"2"], [UIImage imageNamed:@"3"]] sectionSelectedImages:@[[UIImage imageNamed:@"1-selected"], [UIImage imageNamed:@"2-selected"], [UIImage imageNamed:@"3-selected"]]]; // it create size as per your segment total image
[segmentedControl setSelectionIndicatorHeight:4.0f];
[segmentedControl setFrame:CGRectMake(0, 45, 320, 45)];
[segmentedControl setSegmentEdgeInset:UIEdgeInsetsMake(0, 0, 0, 0)];
[segmentedControl addTarget:self action:@selector(segmentedControlChangedValue:) forControlEvents:UIControlEventValueChanged];
[segmentedControl setBackgroundColor:[UIColor blueColor]];
[segmentedControl setSelectionLocation:HMSegmentedControlSelectionLocationDown];
[segmentedControl setSelectionStyle:HMSegmentedControlSelectionStyleTextWidthStrip];
[self.view addSubview:segmentedControl];
- (void)segmentedControlChangedValue:(HMSegmentedControl *)segmentedControl1 {
if (segmentedControl1.selectedSegmentIndex==0) {
}
else if (segmentedControl1.selectedSegmentIndex==1) {
}
else if(segmentedControl1.selectedSegmentIndex==2) {
}
}

我认为你应该使用更高质量的图像。
我是guest,我使用了错误的UIEdgeInset值。背景图片的宽度为:22;高度:30,分隔线图像宽度:11;身高:30有什么建议吗?非常感谢。
你应该尝试60 * 60像素的图像。
