如何为左对齐设置的UIButton的标题？ [英] How to set the title of UIButton as left alignment?

问题描述

我需要从的UIButton 的左边显示的电子邮件地址，但它被定位在中央。

有没有什么办法来对齐设置的左侧的UIButton ？

这是我目前的code：

 的UIButton * emailBtn = [UIButton的页头] initWithFrame：方法CGRectMake（5,30,250，身高+ 15）]。
emailBtn.backgroundColor = [的UIColor clearColor]
[emailBtn的setTitle：obj2.customerEmail forState：UIControlStateNormal]。
emailBtn.titleLabel.font = [UIFont systemFontOfSize：12.5]
[emailBtn setTitleColor：[[[的UIColor页头] initWithRed：0.121绿色：0.472蓝：0.823阿尔法：1]自动释放] forState：UIControlStateNormal]。
[emailBtn addTarget：自我行动：@selector（emailAction :) forControlEvents：UIControlEventTouchUpInside]。
[elementView addSubview：emailBtn]。
[emailBtn发行];
 

解决方案

设置contentHorizo​​ntalAlignment：

  emailBtn.contentHorizo​​ntalAlignment = UIControlContentHorizo​​ntalAlignmentLeft;
 

您可能还需要调整内容左边边界，否则文本将触左边框：

  emailBtn.contentEdgeInsets = UIEdgeInsetsMake（0，10，0，0）;
 

I need to display the email address from left side of a UIButton, but it is being positioned in the centre.

Is there any way to set the alignment to the left side of a UIButton?

This is my current code:

UIButton* emailBtn = [[UIButton alloc] initWithFrame:CGRectMake(5,30,250,height+15)];
emailBtn.backgroundColor = [UIColor clearColor];
[emailBtn setTitle:obj2.customerEmail forState:UIControlStateNormal];
emailBtn.titleLabel.font = [UIFont systemFontOfSize:12.5];
[emailBtn setTitleColor:[[[UIColor alloc]initWithRed:0.121 green:0.472 blue:0.823 alpha:1]autorelease] forState:UIControlStateNormal];
[emailBtn addTarget:self action:@selector(emailAction:) forControlEvents:UIControlEventTouchUpInside];
[elementView addSubview:emailBtn];
[emailBtn release];

解决方案

Set the contentHorizontalAlignment:

emailBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;

You might also want to adjust the content left inset otherwise the text will touch the left border:

emailBtn.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
