我在单击按钮上打开警报弹出窗口,它工作正常,代码是

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"PopUP Title" 
                                                message:@"This is pop up window/ Alert" 
                                               delegate:nil 
                                      cancelButtonTitle:@"OK"
                                      otherButtonTitles:nil];

UIImageView *tempImageView=[[UIImageView alloc]initWithFrame:CGRectMake(20,20,50,50)];
tempImageView.image=[UIImage imageNamed:@"abc.png"];

[alert addSubView:tempImageView]

[alert show];

单击确定按钮时警报框正在关闭,我不想要它,我想在单击窗口上的任何位置时关闭警报框。请帮我。

听起来您实际上是在尝试在 iOS 上重新创建“Toast”。好消息,已经有人这样做了。看到这个项目。

编辑:不想使用 iToast。我喜欢你的风格,代码少。这是我想出的。正如其他人所说,克服模态特性的唯一方法似乎很明显,UIAlertView就是添加一个超级视图来处理触摸事件。但是您不必每次都手动执行此操作,请考虑 subclassing UIAlertView。尝试这样的事情:

编辑: @wagashi,感谢您接受我的回答,并感谢您提醒我这setFrame:是一个调整大小的好地方。您的代码确实发出了一个非常类似于吐司的小警报,但是当我尝试它时,我发现如果消息太长,视图似乎会崩溃。所以我已经修改setFrame:为简单地将警报的大小减小大约一个按钮的大小,并保持在屏幕的中心。这样该课程才能准确地回答问题标题“iOS 如何在任何地方一键关闭 UIAlertView?”

NoButtonAlertView.h

#import <UIKit/UIKit.h>
@interface _NoButtonAlertViewCover : UIView
@property (nonatomic,assign) UIAlertView *delegate;
@end
@interface NoButtonAlertView : UIAlertView
-(id)initWithTitle:(NSString *)title message:(NSString *)message;
@end

NoButtonAlertView.m

#import "NoButtonAlertView.h"
@implementation _NoButtonAlertViewCover
@synthesize delegate = _delegate;
-(void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{
    [self removeFromSuperview];
    [_delegate dismissWithClickedButtonIndex:0 animated:YES];
}
@end
@implementation NoButtonAlertView
-(void)show{
    [super show];
    _NoButtonAlertViewCover *cover = [[_NoButtonAlertViewCover alloc] initWithFrame:[UIScreen mainScreen].bounds];
    cover.userInteractionEnabled = YES;
    cover.backgroundColor = [[UIColor lightGrayColor] colorWithAlphaComponent:.01];
    cover.delegate = self;
    [self.superview addSubview:cover];
}
-(id)initWithTitle:(NSString *)title message:(NSString *)message{
    if ((self = [super initWithTitle:title message:message delegate:nil cancelButtonTitle:nil otherButtonTitles:nil, nil])){
    }
    return self;
}
- (void)setFrame:(CGRect)rect {
    // Called multiple times, 4 of those times count, so to reduce height by 40
    rect.size.height -= 10;
    self.center = self.superview.center;
    [super setFrame:rect];
}
@end

使用这个简单UIAlertView的子类及其UIView作为封面的子类,您可以像使用标准UIAlertView. 像这样:

NoButtonAlertView *alert = [[NoButtonAlertView alloc] initWithTitle:@"Hello" message:@"I am the very model of a modern major general; I'm information, vegitable, animal, and mineral."];
[alert show];

将产生:
