iOS 6.0- UIAlertView无法添加子视图。在较低版本中正常工作 [英] iOS 6.0- UIAlertView failed to addSubview. Works fine in lower version

问题描述

这是我在警报视图中显示表格视图的代码。它在iOS 5.1中完美运行。但是在iOS 6.0中，它不会在警报视图中显示表格视图。

UIAlertTableView.h

  #import< UIKit / UIKit.h>

 @interface UIAlertTableView：UIAlertView {
 //用于装饰

 NSArray *价格; 
 NSString * priceText;

这是怎么回事我用它

  UIAlertTableView * popUpCartItems = [[UIAlertTableView alloc] initWithTitle：@Cart消息：nil delegate ：self cancelButtonTitle：@CloseotherButtonTitles：@CheckOut，nil]; 
 popUpCartItems.tableDelegate = popUpCartItems; 
 popUpCartItems.dataSource = popUpCartItems; 
 popUpCartItems.tableHeight = 132; 
 [popUpCartItems show]; 
  

非常感谢任何帮助

我在iOS 5.0和iOS 6.0上都进行过测试，它对我来说非常适合。

您只需要下载该代码并在项目中使用。

希望这对您有帮助!!! / p>

This is my code to show the table view inside alert view. Its working perfectly in iOS 5.1. But in iOS 6.0 it doesnt show the table view inside alert view.

UIAlertTableView.h

#import <UIKit/UIKit.h>

@class UIAlertView;

@interface UIAlertTableView : UIAlertView {
    // The Alert View to decorate
    UIAlertView *alertView;

    // The Table View to display
    UITableView *tableView;

    // Height of the table
    int tableHeight;

    // Space the Table requires (incl. padding)
    int tableExtHeight;

    id<UITableViewDataSource> dataSource;
    id<UITableViewDelegate> tableDelegate;

    NSArray *names;
    NSArray *prices;
    NSString *priceText;
    NSInteger rowsCount;
    NSInteger total;
}

@property (nonatomic, assign) id dataSource;
@property (nonatomic, assign) id tableDelegate;

@property (nonatomic, readonly) UITableView *tableView;
@property (nonatomic, assign) int tableHeight;
@property (nonatomic, assign) NSInteger total;

- (void)prepare;

@end

UIAlertTableView.m

    // We get the lowest non-control view (i.e. Labels) so we can place the table view just below
    UIView *lowestView;
    int i = 0;
    while (![[self.subviews objectAtIndex:i] isKindOfClass:[UIControl class]]) {
        lowestView = [self.subviews objectAtIndex:i];
        i++;
    }

    CGFloat tableWidth = 262.0f;

    tableView.frame = CGRectMake(11.0f, lowestView.frame.origin.y + lowestView.frame.size.height + 2 * kTablePadding, tableWidth, tableHeight);

    for (UIView *sv in self.subviews) {
        // Move all Controls down

This is how I use it

UIAlertTableView *popUpCartItems = [[UIAlertTableView alloc] initWithTitle:@"Cart" message:nil delegate:self cancelButtonTitle:@"Close" otherButtonTitles:@"CheckOut",nil];
popUpCartItems.tableDelegate = popUpCartItems;
popUpCartItems.dataSource = popUpCartItems;
popUpCartItems.tableHeight = 132;
[popUpCartItems show];

Any help is greatly appreciated

Check the following link

I tested on both iOS 5.0 and iOS 6.0 and its work perfectly for me.

You just need to do download that code and use in your project.

Hope this will help you !!!
