按钮之间的标签在哪里 [英] where are the labels among the buttons

问题描述

在下图中，我试图在每个按钮之间放置一个单字符标签，但如第二张图所示，当我插入标签时，按钮消失并且(如果仔细观察)最后一个按钮的文本移动向右.

In the image below I am attempting to put a single-character label between each button, but as the second image shows, when I do insert the labels, the buttons disappear and (if you look closely) the last button's text moves to the right.

你能帮我得到想要的结果吗?

Can you help me get the desired result, please?

没有标签的按钮

带有标签的按钮

视图控制器.h

@property(nonatomic,assign) UILabel* theSuit;

ViewController.m

ViewController.m

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    NSString* cards = @"AKQJT98765432";

    NSInteger yPipsOrigin = 100;
    NSInteger xPipsOrigin = 100;
    NSInteger xPipsStep = 40.0;
    NSInteger xPipsCurrent = xPipsOrigin;
    // Do any additional setup after loading the view.
    for( int x=0;x<[cards length]; x++ ){
        [cards substringWithRange:NSMakeRange(x,1)];
        UIButton *b= [UIButton buttonWithType:UIButtonTypeRoundedRect];
        xPipsCurrent += xPipsStep;
        [b setTitle:[cards substringWithRange:NSMakeRange(x,1)] forState:UIControlStateNormal];
        [b setTitle:@" " forState:UIControlStateDisabled];
        [b setFrame:CGRectMake(xPipsCurrent, yPipsOrigin, 20, 20)];
        [b setEnabled:YES];
        [b setUserInteractionEnabled:YES];
        [self.view addSubview:b];
        [b addTarget:self action:@selector(spadeButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

        xPipsCurrent = xPipsOrigin + xPipsStep/2;
        for( int x=0;x<[cards length]-1; x++ ){
            xPipsCurrent += xPipsStep;
            UILabel *lab = self.theSuit;
            lab.text = @"Z";
            lab.backgroundColor = [UIColor clearColor];
            lab.center = CGPointMake(xPipsCurrent, yPipsOrigin);
            [self.view addSubview:lab];
        }
    }

}

推荐答案

NSString* cards = @"AKQJT98765432";

NSInteger yPipsOrigin = 100;
NSInteger xPipsOrigin = 100;
NSInteger xPipsStep = 40.0;
NSInteger xPipsCurrent = xPipsOrigin;

for( int x=0;x<[cards length]; x++ )
{
    [cards substringWithRange:NSMakeRange(x,1)];
    UIButton *b= [UIButton buttonWithType:UIButtonTypeRoundedRect];
    xPipsCurrent += xPipsStep;
    [b setTitle:[cards substringWithRange:NSMakeRange(x,1)] forState:UIControlStateNormal];
    [b setTitle:@" " forState:UIControlStateDisabled];
    [b setFrame:CGRectMake(xPipsCurrent, yPipsOrigin, 20, 20)];
    [b setEnabled:YES];
    [b setUserInteractionEnabled:YES];
    [self.view addSubview:b];
    [b addTarget:self action:@selector(spadeButtonPressed:) forControlEvents:UIControlEventTouchUpInside];

    UILabel *lab = [[UILabel alloc] initWithFrame:CGRectMake(xPipsCurrent+b.frame.size.width, yPipsOrigin, 20, 20)];
    lab.text = @"Z";
    lab.textAlignment = NSTextAlignmentCenter;
    lab.backgroundColor = [UIColor clearColor];
    [self.view addSubview:lab];
}
