说明

ZXTheme用于修改全局UI的主题，设置方法与注意点说明以UILabel为例：

• 示例代码

[ZXTheme defaultTheme].zx_labelThemeBlock = ^ZXLabelTheme * _Nonnull(UILabel * _Nonnull label) {
    ZXLabelTheme *labelTheme = [[ZXLabelTheme alloc]init];
    labelTheme.textColor = [UIColor blueColor];
    labelTheme.textAlignment = NSTextAlignmentCenter;
    return labelTheme;
};

• 说明：我们需要修改全局label的主题，则书写[ZXTheme defaultTheme].zx_labelThemeBlock
• 这个block中有一个label对象，代表当前需要设置主题的label
• 这个block需要一个返回值，在设置label主题的block中，这个返回值是ZXLabelTheme对象，创建这个对象，并更改其中的属性即可更改对应的label主题
• 下方示例代码实现将所有文字内容为“测试”的label文字颜色设置为绿色，其他label的文字颜色不变

[ZXTheme defaultTheme].zx_labelThemeBlock = ^ZXLabelTheme * _Nonnull(UILabel * _Nonnull label) {
    ZXLabelTheme *labelTheme = [[ZXLabelTheme alloc]init];
    if([label.text isEqualToString:@"测试"]){
        labelTheme.textColor = [UIColor greenColor];
    }
    return labelTheme;
};

• 下方示例代码实现将所有文字内容为“测试”的label文字颜色设置为绿色，其他label的文字颜色不变，所有label背景色变为红色

[ZXTheme defaultTheme].zx_labelThemeBlock = ^ZXLabelTheme * _Nonnull(UILabel * _Nonnull label) {
    ZXLabelTheme *labelTheme = [[ZXLabelTheme alloc]init];
    if([label.text isEqualToString:@"测试"]){
        labelTheme.textColor = [UIColor greenColor];
    }
    labelTheme.backgroundColor = [UIColor redColor];
    return labelTheme;
};

• 下方示例代码实现将所有文字内容为“测试”的label文字颜色设置为绿色并且背景色变为红色，其他label主题不变

[ZXTheme defaultTheme].zx_labelThemeBlock = ^ZXLabelTheme * _Nonnull(UILabel * _Nonnull label) {
    ZXLabelTheme *labelTheme = [[ZXLabelTheme alloc]init];
    if([label.text isEqualToString:@"测试"]){
        labelTheme.textColor = [UIColor greenColor];
        labelTheme.backgroundColor = [UIColor redColor];
        return labelTheme;
    }else{
        return nil;
    }
};

• 由上方三段示例代码可以得出以下规律：
  1.themeblock返回值为nil，则代表当前label对象不设置主题
  2.ZXLabelTheme对象中属性没有设置，则代表当前label对象中对应属性不设置主题
  3.ZXLabelTheme对象中属性有值，则当前label对象中对应属性用ZXLabelTheme对象的对应属性值，例如labelTheme.textColor有值，则label的textColor为labelTheme.textColor，否则label的textColor为label本身的textColor
• 注意：ZXTheme中设置的主题拥有最高的管理权限，也就意味着，若您在ZXTheme中设置了对应UI控件的主题，则您在其他地方都无法更改对应UI控件的主题

以上是相关注意点和使用技巧说明，设置其他UI控件主题同理，因此下方不再赘述

• ZXCollectionViewTheme所有属性

/**

 */
@property(strong, nonatomic) UIColor *backgroundColor;
/**

 */
@property(strong, nonatomic) UIView *backgroundView;
/**
 设置CollectionView的cell
 */
@property(copy, nonatomic) UICollectionViewCell *(^cellForItemAtIndexPath)(UICollectionViewCell *cell,NSIndexPath *indexPath);
/**
 设置CollectionView的headerView和FfooterView
 */
@property(copy, nonatomic) UICollectionReusableView *(^viewForSupplementaryElement)(UICollectionReusableView *reusableView,NSString *kind,NSIndexPath *indexPath);

自定义其他View或属性的主题

• 例如需要添加UIAlertController的主题设置
• 创建UIAlertController的分类
• 在.m文件中实现

#import "UIAlertController+ZXCustomTheme.h"
#import "ZXTheme.h"
@implementation UIAlertController (ZXCustomTheme)
+ (void)load{
    [self zx_handleThemeWithTargetSelector:@selector(addAction:) handleSelector:@selector(zx_addAction:)];
}
- (void)zx_addAction:(UIAlertAction *)action{
    [action setValue:[UIColor redColor] forKey:@"titleTextColor"];
    [self zx_addAction:action];
}
@end

• 以上代码实现将UIAlertController的actions文字颜色变为红色的效果
