问题描述
我需要在 UIButton 的左侧显示一个电子邮件地址，但它被放置在中间.
I need to display an email address on the left side of a UIButton, but it is being positioned to the centre.
有什么办法可以将对齐设置为 UIButton 的左侧?
Is there any way to set the alignment to the left side of a UIButton?
这是我当前的代码:
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];
推荐答案
设置 contentHorizontalAlignment:
Set the contentHorizontalAlignment:
emailBtn.contentHorizontalAlignment = .left;
您可能还想调整左内嵌的内容，否则文本将触及左边框:
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);
// Swift 3 and up:
emailBtn.contentEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0);
