2、方法
-
由于按钮是有状态的,比如:未点击状态,高亮状态,选中状态,不可用状态等。所以按钮所提供的方法当中很多是根据按钮状态来设置的。
-
buttonWithType::类方法,创建按钮对象时,直接指定按钮类型。取值为枚举。+ (instancetype)buttonWithType:(UIButtonType)buttonType; -
setTitle:forState::default is nil. title is assumed to be single line。根据按钮状态设置文字。- (void)setTitle:(nullable NSString *)title forState:(UIControlState)state; -
setTitleColor:forState::default if nil. use opaque white。根据按钮状态设置文字颜色,默认白色。- (void)setTitleColor:(nullable UIColor *)color forState:(UIControlState)state; -
setTitleShadowColor: forState:: default is nil. use 50% black。 设置文字阴影颜色,默认半透明黑色- (void)setTitleShadowColor:(nullable UIColor *)color forState:(UIControlState)state ; -
setImage: forState:: default is nil. should be same size if different for different states。根据按钮状态设置图片。- (void)setImage:(nullable UIImage *)image forState:(UIControlState)state; -
setBackgroundImage: forState:: 根据按钮状态设置背景图片。- (void)setBackgroundImage:(nullable UIImage *)image forState:(UIControlState)state ; -
setAttributedTitle: forState:: default is nil. title is assumed to be single line.根据按钮状态设置文本属性内容(包括文字大小,颜色等)。假设文字是单行的。- (void)setAttributedTitle:(nullable NSAttributedString *)title forState:(UIControlState)state; -
titleForState: forState::these getters only take a single state value。根据按钮状态获取文本- (nullable NSString *)titleForState:(UIControlState)state; -
titleColorForState: forState:: 根据按钮状态获取文本颜色- (nullable UIColor *)titleColorForState:(UIControlState)state; -
titleShadowColorForState: forState:: 根据按钮状态获取文本阴影颜色- (nullable UIColor *)titleShadowColorForState:(UIControlState)state; -
imageForState: forState:: 根据按钮状态获取图片。- (nullable UIImage *)imageForState:(UIControlState)state; -
backgroundImageForState: forState:: 根据按钮状态获取背景图片。- (nullable UIImage *)backgroundImageForState:(UIControlState)state; -
attributedTitleForState: forState:: 根据按钮状态获取文本属性。- (nullable NSAttributedString *)attributedTitleForState:(UIControlState)state; -
backgroundRectForBounds:: 自定义按钮时,可以更改背景图片在按钮当中的位置。- (CGRect)backgroundRectForBounds:(CGRect)bounds; -
contentRectForBounds:: 自定义按钮时,可以更改整个内容在按钮当中的位置。- (CGRect)contentRectForBounds:(CGRect)bounds; -
titleRectForContentRect:: 自定义按钮时,可以更改Label在按钮当中的位置。- (CGRect)titleRectForContentRect:(CGRect)contentRect; -
imageRectForContentRect:: 自定义按钮时,可以更改图片在按钮当中的位置。- (CGRect)imageRectForContentRect:(CGRect)contentRect;
