通过键盘显示视图 [英] Show a view over the keyboard

问题描述

由于定制的加载子视图，我在iPhone上寻找一种方法，让子视图覆盖键盘而不会解除键盘。现在当子视图加载时，键盘仍然是最顶层的。任何想法？

I am looking for a way on the iPhone, due to a custom 'loading' subview, to have a subview cover the keyboard without dismissing the keyboard. Right now when the subview loads, the keyboard is still topmost. Any ideas?

推荐答案

在窗口上添加加载视图作为子视图。它也将涵盖键盘。这是一个相同的stackoverflow帖子

add your loading view as subview on window. It will cover keyboard too. Here is a stackoverflow post for the same

我的代码

#pragma mark -
#pragma mark Waiting View
- (void)showWaitingView {

    CGRect frame = CGRectMake(90, 190, 32, 32);
    UIActivityIndicatorView* progressInd = [[UIActivityIndicatorView alloc] initWithFrame:frame];
    [progressInd startAnimating];
    progressInd.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;

    frame = CGRectMake(130, 193, 140, 30);
    UILabel *waitingLable = [[UILabel alloc] initWithFrame:frame];
    waitingLable.text = @"Processing...";
    waitingLable.textColor = [UIColor whiteColor];
    waitingLable.font = [UIFont systemFontOfSize:20];;
    waitingLable.backgroundColor = [UIColor clearColor];
    frame = [[UIScreen mainScreen] applicationFrame];
    UIView *theView = [[UIView alloc] initWithFrame:frame];
    theView.backgroundColor = [UIColor blackColor];
    theView.alpha = 0.7;
    theView.tag = 999;
    [theView addSubview:progressInd];
    [theView addSubview:waitingLable];

    [progressInd release];
    [waitingLable release];

    [window addSubview:[theView autorelease]];
    [window bringSubviewToFront:theView];
}

- (void)removeWaitingView {
    UIView *v = [window viewWithTag:999];
    if(v) [v removeFromSuperview];

}
