iphone - ui按钮标题

Question

UIButton *ticketButtonObj=
    [[UIButton alloc]initWithFrame:CGRectMake(140.0f 100.0f, 390.0f, 40.0f)];   
UIImage *buttonicon1=[UIImage alloc];
buttonicon1=[UIImage imageNamed:@"Generalticket.png"];

如何使用 buttonicon1 .. 左对齐设置 ticketButtonObj 的背景？

请帮助我...谢谢和raju的问候。

Answer 1

UIButton *ticketButtonObj = [[UIButton alloc] initWithFrame:CGRectMake(140.0f 100.0f, 390.0f, 40.0f)];
UIImage* buttonicon1 = [UIImage imageNamed:@"Generalticket.png"];
[ticketButtonObj setImage:image forState:UIControlStateNormal];
ticketButtonObj.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;

或者，如果要设置背景图像：

[ticketButtonObj setBackgroundImage:image forState:UIControlStateNormal];

但是您不能设置背景的对齐方式。
