未设置UIbutton的图像和标题

Question

我正在尝试在UIButton上实现图像以及标题。 UIButton的尺寸为86 x96。我需要在顶部嵌入尺寸为86 x 76的图像，并在图像下方嵌入尺寸为86 x 20的标题。

该代码是

UIButton *generalButton = [UIButton buttonWithType:UIButtonTypeCustom];
[generalButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
generalButton.titleLabel.font = [UIFont fontWithName:@"Arial" size:13];
[generalButton setImageEdgeInsets:UIEdgeInsetsMake(0,0,20,0)];
[generalButton setTitleEdgeInsets:UIEdgeInsetsMake(76,0,0,0)];
generalButton.frame = CGRectMake(32,20,86,96);
[generalButton setImage:[UIImage imageNamed:@"flower_icon.png"] forState:UIControlStateNormal];
[generalButton setTitle:@"Flower" forState:UIControlStateNormal];
[self addSubview:generalButton];  

但是问题在于只显示了图像，而标题没有显示。 如果我通过注释代码隐藏图像，那么标题将完美显示。

请帮忙

Answer 1

试试这个代码：

 UIButton *generalButton = [UIButton buttonWithType:UIButtonTypeCustom];
[generalButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
generalButton.titleLabel.font = [UIFont fontWithName:@"Arial" size:13];
[generalButton setImageEdgeInsets:UIEdgeInsetsMake(0,0,20,0)];
[generalButton setTitleEdgeInsets:UIEdgeInsetsMake(30,-50,0,0)];
generalButton.frame = CGRectMake(32,20,86,96);
[generalButton setImage:[UIImage imageNamed:@"RepresentativeIcon.png"] forState:UIControlStateNormal];
[generalButton setTitle:@"Flower" forState:UIControlStateNormal];
[self.view addSubview:generalButton];

Answer 2

请尝试以下代码：

UIButton *generalButton = [UIButton buttonWithType:UIButtonTypeCustom];
    [generalButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
    generalButton.titleLabel.font = [UIFont fontWithName:@"Arial" size:13];
    [generalButton setImageEdgeInsets:UIEdgeInsetsMake(20,22,20,0)];
    [generalButton setTitleEdgeInsets:UIEdgeInsetsMake(50,-30,0,0)];
    generalButton.frame = CGRectMake(32,20,86,96);
    [generalButton setBackgroundColor:[UIColor yellowColor]];
    [generalButton setImage:[UIImage imageNamed:@"Facebook"] forState:UIControlStateNormal];
    [generalButton setTitle:@"Flower" forState:UIControlStateNormal];
    [self.view addSubview:generalButton];

注意：

[generalButton setImageEdgeInsets:UIEdgeInsetsMake(20,22,20,0)];
[generalButton setTitleEdgeInsets:UIEdgeInsetsMake(50,-30,0,0)];

这两行对重新定位标题和图像起着主要作用，因此请根据图像的高度，宽度和标题长度设置所有参数。

在此代码中，我将更改图像名称，也更改了按钮的背景色，因此请根据您的数据进行更改。

希望这会帮助你。
