我需要在UIButton的左侧显示一个电子邮件地址，但它被定位到中心。
有什么方法来设置对齐到UIButton的左边?
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];
@DyingCactus的代码有一个小错误。
下面是正确的解决方案，添加一个UILabel到UIButton来对齐按钮文本，以更好地控制按钮的“标题”:
NSString *myLabelText = @"Hello World";
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeCustom];
// position in the parent view and set the size of the button
myButton.frame = CGRectMake(myX, myY, myWidth, myHeight);
CGRect myButtonRect = myButton.bounds;
UILabel *myLabel = [[UILabel alloc] initWithFrame: myButtonRect];
myLabel.text = myLabelText;
myLabel.backgroundColor = [UIColor clearColor];
myLabel.textColor = [UIColor redColor];
myLabel.font = [UIFont fontWithName:@"Helvetica Neue" size:14.0];
myLabel.textAlignment = UITextAlignmentLeft;
[myButton addSubview:myLabel];
[myLabel release];
希望这有助于....
