解决方案

是的，它是当您使用图像正常的行为属性。

使用 和backgroundImage 属性而不是 图片 之一，是这样的：

  [按钮了setBackgroundImage：[UIImage的imageNamed：[的NSString stringWithFormat：@ikonki％d.png，我] forState：UIControlStateNormal];
 

更新＃1：

要重新定​​位按钮的标题下的按钮，用这样的方式：

  [按钮setTitleEdgeInsets：UIEdgeInsetsMake（0.f，0.f，-60.f，0.f）]; //对齐值的特定按钮
[按钮setClipsToBounds：假];
 

更新＃2：

要更改标题的字体，试试这个：

  [button.titleLabel并入setfont：[UIFont systemFontOfSize：34.f]]; //设置字体大小，你的愿望
 

I have a simple problem with my buttons. Title is not visible. My code is :

    UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
    [button setImage:[UIImage imageNamed:[NSString stringWithFormat:@"ikonki%d.png",i]] forState:UIControlStateNormal];
    [button setTitle:@"Normal" forState:UIControlStateNormal];
    [button setTitleColor: [UIColor whiteColor] forState: UIControlStateNormal];
    [button setEnabled:YES];

    [button addTarget:self
               action:@selector(buttonHandler:) 
     forControlEvents:UIControlEventTouchUpInside];


    button.tag = i;
    button.frame = CGRectMake(10. + 77. * i, 125., 68 , 68);


    [self.view addSubview:button];

解决方案

yep, it is normal behaviour when you are using the image property.

use the backgroundImage property instead of the image one, like this:

[button setBackgroundImage:[UIImage imageNamed:[NSString stringWithFormat:@"ikonki%d.png",i]] forState:UIControlStateNormal];

UPDATE #1:

to reposition the title of the button under the button, use this way:

[button setTitleEdgeInsets:UIEdgeInsetsMake(0.f, 0.f, -60.f, 0.f)]; // align the values for your specific button
[button setClipsToBounds:false];

UPDATE #2:

to change the font of the title, try this one:

[button.titleLabel setFont:[UIFont systemFontOfSize:34.f]]; // set the font size what you desire
