//    //声明一个label对象

UILabel *tiplabel = [[UILabel alloc]initWithFrame:CGRectMake(100, SCREENHEIGHT/2-80, SCREENWIDTH-200, 80)];

//设置提示内容

tiplabel.backgroundColor = DJLightGrayColor;

tiplabel.layer.cornerRadius=5;

tiplabel.layer.masksToBounds = YES;

tiplabel.textAlignment = NSTextAlignmentCenter;

tiplabel.textColor = [UIColor whiteColor];

[self.tableView addSubview:tiplabel];

//

if (pastboad.string) {

NSLog(@"复制链接成功");

[tiplabel setText:@"链接复制成功"];

}else{

NSLog(@"复制链接失败");

[tiplabel setText:@"链接复制失败"];

}

//设置时间和动画效果

[UIView animateWithDuration:2.0 animations:^{

tiplabel.alpha =0.0;

} completion:^(BOOL finished) {

[tiplabel removeFromSuperview];

}];
