Cocoa uibutton字体子类

我的UIButton类中有以下方法：

- (id)initWithCoder:(NSCoder *)aDecoder{
self = [super initWithCoder:aDecoder];
if (self) {
    // Initialization code

    self.titleLabel.font = [UIFont fontWithName:@"Chalkduster" size:16];
    self.titleLabel.lineBreakMode = UILineBreakModeWordWrap;

    self.titleLabel.textColor = [UIColor greenColor];

}
return self;
}

效果很好，只是我看不到按钮周围的边框：知道为什么吗？我还需要做些什么来显示按钮边框

谢谢

不要子类化按钮，在IB中做所有事情会更好。这就是你如何实现你想要的：

选择按钮->转到属性检查器->类型->选择圆形矩形。这将为您提供默认的按钮外观

然后选择font（按T字母），如下所示：

还可以选择字体后面的文本颜色

结果：

//create the button with RoundedRect type
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

//set the position of the button
button.frame = CGRectMake(100, 150, 100, 30);

//set the button's title
[button setTitle:@"Click Me!" forState:UIControlStateNormal];

//set the button's font
button.titleLabel.font = [UIFont fontWithName:@"Chalkduster" size:16];

//set the button's line break mode
button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;

//set the button's text color
[button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
//button.titleLabel.textColor = [UIColor greenColor]; // don't use this because button's text color after clicking it will be blue (default).

//add the button to the view
[self.view addSubview:button];

编辑：

//create the button with RoundedRect type
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

//set the position of the button
button.frame = CGRectMake(100, 150, 100, 30);

//set the button's title
[button setTitle:@"Click Me!" forState:UIControlStateNormal];

//set the button's font
button.titleLabel.font = [UIFont fontWithName:@"Chalkduster" size:16];

//set the button's line break mode
button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;

//set the button's text color
[button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
//button.titleLabel.textColor = [UIColor greenColor]; // don't use this because button's text color after clicking it will be blue (default).

//add the button to the view
[self.view addSubview:button];

以编程方式创建按钮：

//create the button with RoundedRect type
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

//set the position of the button
button.frame = CGRectMake(100, 150, 100, 30);

//set the button's title
[button setTitle:@"Click Me!" forState:UIControlStateNormal];

//set the button's font
button.titleLabel.font = [UIFont fontWithName:@"Chalkduster" size:16];

//set the button's line break mode
button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;

//set the button's text color
[button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
//button.titleLabel.textColor = [UIColor greenColor]; // don't use this because button's text color after clicking it will be blue (default).

//add the button to the view
[self.view addSubview:button];

结果：

//create the button with RoundedRect type
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

//set the position of the button
button.frame = CGRectMake(100, 150, 100, 30);

//set the button's title
[button setTitle:@"Click Me!" forState:UIControlStateNormal];

//set the button's font
button.titleLabel.font = [UIFont fontWithName:@"Chalkduster" size:16];

//set the button's line break mode
button.titleLabel.lineBreakMode = UILineBreakModeWordWrap;

//set the button's text color
[button setTitleColor:[UIColor greenColor] forState:UIControlStateNormal];
//button.titleLabel.textColor = [UIColor greenColor]; // don't use this because button's text color after clicking it will be blue (default).

//add the button to the view
[self.view addSubview:button];

注意：不要使用

textColor

，因为单击按钮后的文本颜色将默认为蓝色。

嘿，贾斯汀，你的教程很棒！只是我使用了这么多这种风格的按钮，这样可以更快地更改类，而不是每次都不断更改属性。你知道我需要完成的最后一步吗？@RobW是的，更改类会更快，但复制创建按钮也会足够快。所以你可以这么做。关于编程：据我所知，按钮的类型在创建时无法更改（您需要更改为

uibuttontyperoundredrect

），因此，如果您想通过编程实现这一点，请在代码中以编程方式创建所有按钮，而不使用IB。@RobW查看更新的答案。我添加了如何以编程方式创建按钮的代码，并对其进行了注释。
