Question

标签上没有显示空格后向字符串添加空格。我使用以下方法来获取它。我想在字符串之后添加空格，并且应该在标签上显示。

NSString *text = @"ABCD";
text = [text stringByAppendingString:@" "];

但是当我跑步时它只显示为“ABCD”。

我在tableviewcell上显示标签，我正在将文本对齐设置为右

Answer 1

应该是

text=[text stringByAppendingString:@"\t"];

<强>更新

任何追加方法都会起作用，我想你需要一些空间试试这个

r.js

感谢。

Answer 2

检查设计。我检查了你的代码和NSLog它。用于测试

    <Style TargetType="{x:Type Button}">
        <Setter Property="Background" Value="Orange"/>
        <Style.Triggers>
            <Trigger Property="IsMouseOver" Value="True">
                <Setter Property="Background" Value="LightGray"/>
            </Trigger>
        </Style.Triggers>
    </Style>

添加了子类UILabel并添加了一个edgeInsets属性。

customLabel.h

#import <UIKit/UIKit.h>

@interface customLabel : UILabel

@property (nonatomic, assign) UIEdgeInsets edgeInsets;

@end

customLabel.m

#import "customLabel.h"

@implementation customLabel

- (id)initWithFrame:(CGRect)frame{
 self = [super initWithFrame:frame];
 if (self) {
    self.edgeInsets = UIEdgeInsetsMake(0, 0, 0, 2);
 }
 return self;
}

- (void)drawTextInRect:(CGRect)rect {
  [super drawTextInRect:UIEdgeInsetsInsetRect(rect, self.edgeInsets)];
}

@end

ViewController.m

title = [[customLabel alloc] initWithFrame:CGRectMake(75, 25, 200, 14)];
[title setTextColor:[UIColor whiteColor]];
[title setFont:[UIFont systemFontOfSize:14]];
[title setText:@"Text"];
[self.view addSubview:title];

Answer 4

请试试这个

NSString *text = @"ABCD";
text = [text stringByAppendingString:@" "];

NSMutableAttributedString *string = [[NSMutableAttributedString alloc] initWithString:[NSString stringWithFormat:@"%@.", text]];

[string addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0,string.length-1)];

[string addAttribute:NSForegroundColorAttributeName value:[UIColor clearColor] range:NSMakeRange(string.length-1,1)];
label.attributedText = string;

如果您想更改标签的文字颜色而不是更改：

[string addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(0,string.length-1)];

Answer 5

试试这个：

text = [NSString stringWithFormat:@"%@ ", text];

Answer 6

NSString *yourString = @"ABCD";    
NSString *spaceString = @" ";
NSString *finalString = [NSString stringWithFormat:@"%@%@",yourString,spaceString];
