An easy way to change theme through NSObject's category for iOS.
NSObject+PYThemeExtension
pod "PYTheme"
#import <NSObject+PYThemeExtension.h>
PYTheme
文件夹中的所有文件拽入项目中#import "NSObject+PYThemeExtension.h"
// 按钮的背景色添加到主题色池中
[button py_addToThemeColorPool:@"backgroundColor"];
// 设置按钮选中时字体颜色添加到主题色池中
[button py_addToThemeColorPoolWithSelector:@selector(setTitleColor:forState:) objects:@[PYTHEME_THEME_COLOR, @(UIControlStateSelected)]];
// 设置tabBar选中时字体颜色添加到主题色池中
NSMutableDictionary *attrSel = [NSMutableDictionary dictionary];
attrSel[NSForegroundColorAttributeName] = PYTHEME_THEME_COLOR;
[childController.tabBarItem py_addToThemeColorPoolWithSelector:@selector(setTitleTextAttributes:forState:) objects:@[attrSel, @(UIControlStateSelected)]];
// 设置主题色为红色
[self py_setThemeColor:[UIColor redColor]];
// 添加tabBarItem到主题图片池中
[tabBarItem py_addToThemeImagePool];
// 重新加载主题图片,并设置主题色为红色
[self py_reloadThemeImageWithThemeColor:[UIColor redColor] setting:^(const NSArray<id> *objects) {
// 根据控件类型完成相关设置
}
UIAppearance
,否则将无法添加到主题池中
// 获取全局navBar
UINavigationBar *navBar = [UINavigationBar appearance];
// 添加背景色到主题色池中
[navBar py_addToThemeColorPool:@"barTintColor"];
使用py_addToThemeColorPoolWithSelector:objects:
设置参数数组时注意:
如果要使图片随着主题色变化而渲染成主题颜色,需要设置RenderingMode
为:UIImageRenderingModeAlwaysTemplate
