iOS开发中自定义弹出框

很多时候,iOS开发中需要弹出提示框来提示用户一些信息,但是MBProgressHud的显示可能会导致文字显示不全,这个时候就需要自定义一个弹出框来显示自己需要的文字.

-(void)updataWindows {

windows = [UIApplication sharedApplication].keyWindow;

view = [[UIView alloc]initWithFrame:CGRectMake(40, SCREEN_HEIGHT/2 - 40, SCREEN_WIDTH - 80, 80)];

view.backgroundColor = [UIColor blackColor];

view.layer.masksToBounds = YES;

view.layer.cornerRadius = 8.0f;

label = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, view.bounds.size.width, 80)];

label.numberOfLines = 3;

label.text = @" 您的信息已经重新提交,我们正在在加紧审核,请稍侯 ";

label.textColor = [UIColor whiteColor];

label.textAlignment = NSTextAlignmentCenter;

[windows addSubview:view];

[view addSubview:label];

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2 * NSEC_PER_SEC)),dispatch_get_main_queue(), ^{

//2秒以后移除view

[view removeFromSuperview];

});

}

这样就可以做出和MBProgressHud相似的效果了.
