Ios UISegmentControl以编程方式分段框架

我以以下方式使用段控件

    CGFloat segmentWidth = 70;
    CGFloat segmentHeight = 40;
    NSMutableArray *arr = [[NSMutableArray alloc] init];
    for (HCIPGRentDetail *object in self.pgHouse.rents) {
        [arr addObject:object.roomTypeId];
    }
    UISegmentedControl *sharingSegmentControl = [[UISegmentedControl alloc] initWithItems:arr];
    [sharingSegmentControl setApportionsSegmentWidthsByContent:YES];
    sharingSegmentControl.frame = CGRectMake(0, 0, self.pgHouse.rents.count * segmentWidth, segmentHeight);
    for (int i = 0; i < sharingSegmentControl.numberOfSegments; i++) {
        [sharingSegmentControl setWidth:segmentWidth forSegmentAtIndex:i];
        [sharingSegmentControl setTitle:arr[i] forSegmentAtIndex:i];
    }
    sharingSegmentControl.center = CGPointMake(self.view.center.x, currentHeight + sharingSegmentControl.frame.size.height/2);
    currentHeight += sharingSegmentControl.frame.size.height;
    [sharingSegmentControl.layer setBorderColor:[UIColor redColor].CGColor];
    [sharingSegmentControl.layer setBorderWidth:1.0f];
    [sharingSegmentControl setSelectedSegmentIndex:0];
    [sharingSegmentControl setBackgroundColor:[UIColor blueColor]];
    [sharingSegmentControl setSegmentedControlStyle:UISegmentedControlStyleBar];
    [self.mainScrollView addSubview:sharingSegmentControl];

CGFloat段宽度=70；
CGFloat段高度=40；
NSMutableArray*arr=[[NSMutableArray alloc]init]；
for（self.pgHouse.rents中的HCIPGRentDetail*对象）{
[arr addObject:object.roomTypeId]；
}
UISegmentedControl*sharingSegmentControl=[[UISegmentedControl alloc]initWithItems:arr]；
[sharingSegmentControl SetArrightsSegmentWidthsByContent:是]；
sharingSegmentControl.frame=CGRectMake（0,0，self.pgHouse.rents.count*segmentWidth，segmentHeight）；
对于（int i=0；i

它只显示带有蓝色背景和红色的段控件，这些段得到一个类似{0,0}，{0,29}的帧（调试器）。不明白我错过了什么

调试器这样说

<__NSArrayM 0x1411be30>(
<UISegment: 0x1411bd60; frame = (0 0; 0 29); opaque = NO; layer = <CALayer: 0x1411bd30>>,
<UISegment: 0x1411a1c0; frame = (0 0; 0 29); opaque = NO; layer = <CALayer: 0x1411b220>>
)

我复制了您的代码并对其进行了一点编辑，因此这对我很有用：

CGFloat segmentWidth = 70;
CGFloat segmentHeight = 40;

UISegmentedControl *sharingSegmentControl = [[UISegmentedControl alloc] initWithItems:@[@"AAA", @"BBB"]];
//[sharingSegmentControl setApportionsSegmentWidthsByContent:YES];
sharingSegmentControl.frame = CGRectMake(0, 0, sharingSegmentControl.numberOfSegments * segmentWidth, segmentHeight);
for (int i = 0; i < sharingSegmentControl.numberOfSegments; i++) {
    [sharingSegmentControl setWidth:segmentWidth forSegmentAtIndex:i];
    //[sharingSegmentControl setTitle:arr[i] forSegmentAtIndex:i];
}
[sharingSegmentControl.layer setBorderColor:[UIColor redColor].CGColor];
[sharingSegmentControl.layer setBorderWidth:1.0f];
[sharingSegmentControl setSelectedSegmentIndex:0];
[sharingSegmentControl setBackgroundColor:[UIColor blueColor]];
[sharingSegmentControl setSegmentedControlStyle:UISegmentedControlStyleBar];
[self.view addSubview:sharingSegmentControl];

CGFloat段宽度=70；
CGFloat段高度=40；
UISegmentedControl*sharingSegmentControl=[[UISegmentedControl alloc]initWithItems:@[@“AAA”，“BBB”]；
//[sharingSegmentControl SetArrightsSegmentWidthsByContent:是]；
sharingSegmentControl.frame=CGRectMake（0,0，sharingSegmentControl.numberOfSegments*segmentWidth，segmentHeight）；
对于（int i=0；i

结果表明，色调是问题所在。可能段控制将色调默认值作为清晰颜色或其他颜色

不知怎的，当我刚设置色调时。我获得了正确的帧，显示正确。

您的对象是否包含值？是的，它包含值。标题也设置正确。问题在于中心，在指定帧后设置中心。”中心在其superview的坐标系内指定，并以点为单位进行测量。设置此属性会相应地更改帧属性的值“@pawan并不能真正解释为什么将段（所有段）的宽度设置为0.No。这对我不起作用。检查我编辑的问题。
