#import <Foundation/Foundation.h>
#import <UIKit/UIKit.h>
@interface Myview:nsobject

+ (UIButton *) Creatbuttonwithframe: (CGRect) Frame title: (NSString *) title tag: (nsinteger) tag tintcolor: (Uicolor *) Tintcolor backgroundcolor: (Uicolor *) backgroundcolor;

@end

#import "MyView.h"

@implementation MyView

+ (UIButton *) Creatbuttonwithframe: (CGRect) Frame title: (NSString *) title tag: (nsinteger) tag tintcolor: (Uicolor *) Tintcolor backgroundcolor: (Uicolor *) backgroundcolor{
UIButton *button = [UIButton buttonwithtype:uibuttontypecustom];
[Button Settitle:title Forstate:uicontrolstatenormal];
Button.tag = tag;
Button.backgroundcolor = BackgroundColor;
Button.tintcolor= Tintcolor;
Button.frame = frame;
[Button Settitlecolor:tintcolor Forstate:uicontrolstatenormal];
return button;
}
