ios - PopOver ViewController 屏幕尺寸不一致

Question

我创建了一个弹出 View Controller ，大小为 300*250，但是一旦我单击弹出按钮，它会显示比我定义的更大的 View 。

#import <UIKit/UIKit.h>

@interface ZDPopViewController : UIViewController
@property (strong, nonatomic) IBOutlet UITableView *zdTableView;
@property (strong, nonatomic) NSArray *tableData;
@property (strong,nonatomic) UIPopoverController * popoverController;


@end

#import "ZDPopViewController.h"

@interface ZDPopViewController ()

@end

@implementation ZDPopViewController
@synthesize zdTableView,tableData,popoverController;

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view.

     tableData=[[NSArray alloc]initWithObjects:@"TWT",@"TVD",@"TVDSS",@"FREQ", nil];

    self.zdTableView.backgroundColor=[UIColor blackColor];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
    // Return the number of sections.
    return 1;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
    // Return the number of rows in the section.
    return [tableData count];
}

- (void)viewWillAppear:(BOOL)animated
{
    self.popoverController.popoverContentSize = CGSizeMake(320, 220);
    [super viewWillAppear:animated];
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier=@"Cell";

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
    [cell.textLabel setText:[self.tableData objectAtIndex:indexPath.row]];


    // Configure the cell...

    return cell;
}

模拟尺寸并没有定义view controller的尺寸，它只是用来在storyboard中显示那个尺寸的view controller。

要更改在 View 中使用这个的大小将出现在 View Controller 中-

- (void)viewWillAppear:(BOOL)animated
{
   CGSize size = CGSizeMake(320, 200); // The size of view in popover you want
   self.contentSizeForViewInPopover = size;
   [super viewWillAppear:animated];
}

试试这篇文章 iOS 7 -

popoverController.popoverContentSize = CGSizeMake(320, 845);

同时添加 -

[popoverViewController setPreferredContentSize:CGSizeMake(248.0,216.0)];
