ios - 用户界面按钮 : How to set image and text using imageEdgeInsets and titleEdgeInsets?

Question

我有一个应用程序，其中使用 UIButton 以及 title 和 UIImage。他们的对齐似乎是第一个标题，然后是UIImage。

我试过这个:

[dropdownbutton setImage: [UIImage imageNamed:@"down_sml_arrow.png"] 
                                     forState:UIControlStateNormal];
CGFloat spacing = 10; // the amount of spacing to appear between image and title
dropdownbutton.imageEdgeInsets = UIEdgeInsetsMake(0, 0, 0, spacing);
dropdownbutton.titleEdgeInsets = UIEdgeInsetsMake(0, spacing, 0, 0);
[dropdownbutton setTitle:@"Your text" forState:UIControlStateNormal];

但是这里UIImage出现在标题之前。有人能指出我哪里出错了吗？

Answer 1

替代

UIImageView *imageView1=[[UIImageView alloc]init];
UIButton *dropdownbutton=[UIButton buttonWithType:UIButtonTypeRoundedRect];
dropdownbutton.frame=CGRectMake(50, 50, 120, 50);
imageView1.image=[UIImage imageNamed:@"arrows.png"];
imageView1.frame=CGRectMake(85, 12, 25, 25);
dropdownbutton.contentHorizontalAlignment = UIControlContentHorizontalAlignmentLeft;
[dropdownbutton addSubview:imageView1];
CGFloat spacing = 10; // the amount of spacing to appear between image and title
dropdownbutton.titleEdgeInsets = UIEdgeInsetsMake(0, spacing, 0, 0);
[dropdownbutton setTitle:@"Your text" forState:UIControlStateNormal];
[self.view addSubview:dropdownbutton];
