Question

I need to display an email address on the left side of a UIButton, but it is being positioned to 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];

Answer 1

Set the contentHorizontalAlignment:

// Swift 
emailBtn.contentHorizontalAlignment = .left;

// Objective-C
emailBtn.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;

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

// Swift 3 and up:
emailBtn.contentEdgeInsets = UIEdgeInsets(top: 0, left: 10, bottom: 0, right: 0);

// Objective-C
emailBtn.contentEdgeInsets = UIEdgeInsetsMake(0, 10, 0, 0);
