Question

我想知道我怎么可以创建自定义的UIButton用的UILabel内像这样

Answer 1

看看这个教程CIMGF Fun with UIButtons and core animation layers

或者：IphoneDevelopment: Programmatic gradient buttons

你基本上只是创建您的UIButton的子类实施定制图纸。 然后你可以做任何你想要的。这两个教程可以帮助您创建您想要的样式，请记住，如果您不想过多地使用图形代码，也可以使用图像。

你可以这样做：

int i=0; 
UIButton *customButton=[UIButton buttonWithType:UIButtonTypeRoundedRect]; 

//Set the height of your button, that will depend on how much text you will be putting 
//inside 
[customButton setFrame:CGRectMake(3,40,315,130)]; 

for(i=0; i<7; i++){ 
    //Their position will change depending on which label you are adding 
    UILabel *leftLabel=[[UILabel alloc] initWithFrame:CGRectMake(5, 5+(17*i), 150, 12)]; 
    UILabel *rightLabel=[[UILabel alloc] initWithFrame:CGRectMake(160, 5+(17*i), 150, 12)]; 

    //Set the text for each label 
    [leftLabel setText:[NSString stringWithFormat:@"Left %d",i+1]]; 
    [rightLabel setText:[NSString stringWithFormat:@"Right %d",i+1]]; 

    //Set the backgroudn as clear to be able to see the background of your button 
    [leftLabel setBackgroundColor:[UIColor clearColor]]; 
    [rightLabel setBackgroundColor:[UIColor clearColor]]; 

    //Add those labels 
    [customButton addSubview:leftLabel]; 
    [customButton addSubview:rightLabel]; 

    //Do your memory management 
    [leftLabel release]; 
    [rightLabel release]; 
}
