【问题描述】：

问题是，如果我使用文本，我可以添加任意多的片段，但如果我使用图像，则意味着我无法在 iphone 上添加超过 6 个片段。

帮帮我。

    UIImage* resetImage = [UIImage imageNamed:@"Reset_V1"];
    UIImage* wlwwImage = [UIImage imageNamed:@"Reset_V1"];
    UIImage* huImage = [UIImage imageNamed:@"HU_PI_V1"];
    UIImage* panImage = [UIImage imageNamed:@"Panning_V1"];
    UIImage* disImage = [UIImage imageNamed:@"Distance_V1"];
    UIImage* areaImage = [UIImage imageNamed:@"Reset_V1"];
    UIImage* clrImage = [UIImage imageNamed:@"Clear_V1"];
    UIImage* presetImage = [UIImage imageNamed:@"Presets_V1"];

        mySegments = [[NSArray alloc] initWithObjects: wlwwImage,panImage,huImage,disImage,areaImage,resetImage,clrImage,presetImage, nil];
   segmentControl = [[UISegmentedControl alloc] initWithItems:mySegments];
    CGRect myFrame = CGRectMake(0, 65, 320, 35);
    segmentControl.frame = myFrame;
    [segmentControl addTarget:self action:@selector(whichSegment:) forControlEvents:UIControlEventValueChanged];
    [self.view addSubview:segmentControl];

【问题讨论】：

嗨，我提交了答案，演示项目是帮助还是还需要更多？

【参考方案1】：

我尝试使用相同的代码，它可以工作输出：

代码：

    UIImage* resetImage = [UIImage imageNamed:@"Image"];
    UIImage* wlwwImage = [UIImage imageNamed:@"Image"];
    UIImage* huImage = [UIImage imageNamed:@"Image"];
    UIImage* panImage = [UIImage imageNamed:@"Image"];
    UIImage* disImage = [UIImage imageNamed:@"Image"];
    UIImage* areaImage = [UIImage imageNamed:@"Image"];
    UIImage* clrImage = [UIImage imageNamed:@"Image"];
    UIImage* presetImage = [UIImage imageNamed:@"Image"];
    UIImage* presetImage1 = [UIImage imageNamed:@"Image"];
    UIImage* presetImage2= [UIImage imageNamed:@"Image"];
    UIImage* presetImage3= [UIImage imageNamed:@"Image"];

    NSArray *mySegments = [[NSArray alloc] initWithObjects: wlwwImage,panImage,huImage,disImage,areaImage,resetImage,clrImage,presetImage,presetImage1,presetImage2,presetImage3, nil];
    UISegmentedControl *segmentControl = [[UISegmentedControl alloc] initWithItems:mySegments];
    CGRect myFrame = CGRectMake(0, 65, 320, 35);
    segmentControl.frame = myFrame;
    [self.view addSubview:segmentControl];

如果您的图片路径无效，那么它将仅显示正确图片的片段

代码（有错误）

// Do any additional setup after loading the view, typically from a nib.
    UIImage* resetImage = [UIImage imageNamed:@"Image"];
    UIImage* wlwwImage = [UIImage imageNamed:@"Image"];
    UIImage* huImage = [UIImage imageNamed:@"Image"];
    UIImage* panImage = [UIImage imageNamed:@"Image"];
    UIImage* disImage = [UIImage imageNamed:@"Image"];
    UIImage* areaImage = [UIImage imageNamed:@"Image1"]; // wrong image name
    UIImage* clrImage = [UIImage imageNamed:@"Image1"]; // wrong image name
    UIImage* presetImage = [UIImage imageNamed:@"Image1"]; // wrong image name
    UIImage* presetImage1 = [UIImage imageNamed:@"Image1"]; // wrong image name
    UIImage* presetImage2= [UIImage imageNamed:@"Image1"]; // wrong image name
    UIImage* presetImage3= [UIImage imageNamed:@"Image1"]; // wrong image name

    NSArray *mySegments = [[NSArray alloc] initWithObjects: wlwwImage,panImage,huImage,disImage,areaImage,resetImage,clrImage,presetImage,presetImage1,presetImage2,presetImage3, nil];
    UISegmentedControl *segmentControl = [[UISegmentedControl alloc] initWithItems:mySegments];
    CGRect myFrame = CGRectMake(0, 65, 320, 35);
    segmentControl.frame = myFrame;
    [self.view addSubview:segmentControl];
