视图样式问题

    UILabel * label = [[UILabel alloc] initWithFrame:CGRectZero addToView:self.view];
    label.backgroundColor = [UIColor redColor];
    label.font = [UIFont systemFontOfSize:16];
    label.text = @"dfadfadfadfadfjka;fka;dfja";
    label.layer.borderColor = [UIColor yellowColor].CGColor;
    label.layer.borderWidth = 1;
    [label mas_makeConstraints:^(MASConstraintMaker *make) {
        make.center.mas_equalTo(self.view);
    }];

前些日子写项目 UI图都出来了 那就做呗 突然看见一个界面上面 有78个标签 出来内容不一样 其他的都是一样的 什么 ？ 难道让我把上面的代码复制78份开什么鬼玩笑 我不要！！！ 怎么办呢 想办法呗 心情一不好就写了个工具 UIView+FunctionExtension.h

@interface UIView (StyleFormat)

/// 对象最好为同一条继承链上面的实例

/// 共享样式
@property (nonatomic, copy) void (^ shareStyle) (id sourceView);
/// 独有样式
@property (nonatomic, copy) void (^ uniqueStyle) (id sourceView);

// 有
- (void)shareStyle:(void(^)(id sourceView))share uniqueStyle:(void(^)(id sourceView))unique;
// 无循环引用问题
- (void)configureStyle:(void(^)(id sourceView))style;

@end

UIView+FunctionExtension.m

@implementation UIView (StyleFormat)

- (void)setShareStyle:(void (^)(id))shareStyle {
    if (shareStyle != nil) {
        shareStyle(self);
    }
    objc_setAssociatedObject(self, @selector(shareStyle), shareStyle, OBJC_ASSOCIATION_COPY_NONATOMIC);
}

- (void (^)(id))shareStyle {
    return objc_getAssociatedObject(self, _cmd);
}


- (void)setUniqueStyle:(void (^)(id))uniqueStyle {
    if (uniqueStyle != nil) {
        uniqueStyle(self);
    }
    objc_setAssociatedObject(self, @selector(uniqueStyle), uniqueStyle, OBJC_ASSOCIATION_COPY_NONATOMIC);
}

- (void (^)(id))uniqueStyle {
    return objc_getAssociatedObject(self, _cmd);
}


- (void)shareStyle:(void(^)(id sourceView))share uniqueStyle:(void(^)(id sourceView))unique {
    self.shareStyle  = share;
    self.uniqueStyle = unique;
}


+ (BOOL)resolveInstanceMethod:(SEL)sel {
    NSString * selName = NSStringFromSelector(sel);
    if ([selName hasPrefix:@"set"] == YES) {
        class_addMethod([self class], sel, (IMP)realizationFunction, "v@:");
        return YES;
    } else {
        return [super resolveInstanceMethod:sel];
    }
}

void realizationFunction(id obj, SEL _cmd) {
//    NSLog(@"%@:%@", obj, NSStringFromSelector(_cmd));
}

- (void)configureStyle:(void(^)(id sourceView))style {
    if (style != nil) {
        style(self);
    }
}

@end

好了 该死的重复代码就没解决了 上面的代码可以更换为这种

UILabel * label0 = [[UILabel alloc] initWithFrame:CGRectZero addToView:self.view];
[label0 shareStyle:^(UILabel * sourceView) {
    sourceView.backgroundColor = [UIColor redColor];
    sourceView.font = [UIFont systemFontOfSize:16];
    sourceView.layer.borderColor = [UIColor yellowColor].CGColor;
    sourceView.layer.borderWidth = 1;
} uniqueStyle:^(UILabel * sourceView) {
    sourceView.text = @"dfadfadfadfadfjka;fka;dfja";
}];
[label0 mas_makeConstraints:^(MASConstraintMaker *make) {
    make.center.mas_equalTo(self.view);
}];

UILabel * label1 = [[UILabel alloc] initWithFrame:CGRectZero addToView:self.view];
UILabel * label2 = [[UILabel alloc] initWithFrame:CGRectZero addToView:self.view];
label1.shareStyle = label0.shareStyle;
label2.shareStyle = label0.shareStyle;

是不是比复制一份好的多呢 喜欢的话点个赞呗 各位看官老爷们 附上CSDN的链接 http://blog.csdn.net/betrayalpromise/article/details/78790916
