UILabel
使用
UILabel *nameL=YLable.yfont(UIFont(20)).ytextColor(RGBOF(0xffffff)).InView(headView);
UILabel+LinkBlock.h
#import
#define YTLable [UILabel new]
@interface UILabel (LinkBlock)
+(UILabel *)Init;
- (UILabel * (^)(CGRect bounds))ybounds;
- (UILabel * (^)(CGRect frame))yframe;
- (UILabel * (^)(UIView *View))InView;
- (UILabel * (^)(NSString *text))ytext;
- (UILabel * (^)(UIFont *font))yfont;
- (UILabel * (^)(UIColor *textColor))ytextColor;
- (UILabel * (^)(NSTextAlignment textAlignment))ytextAlignment;
- (UILabel * (^)(NSInteger numberOfLines))ynumberOfLines;
- (UILabel * (^)(UIColor *backgroundColor))ybackgroundColor;
- (UILabel * (^)(NSAttributedString *attributedText))yattributedText;
- (UILabel * (^)(CGFloat cornerRadius))ycornerRadius;
@end

函数编程
函数做完操作后，返回对象本身。
