Question

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

怎樣才能將buttoniconObj的背景與buttonicon1 ..設置為左對齊？

請幫我...謝謝拉朱的問候。

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，如果您想設置背景圖片：

[ticketButtonObj setBackgroundImage:image forState:UIControlStateNormal];

但是您不能為背景設置對齊方式。
