线程 1：断点 5.1：将'MWPhotoBrowser *'发送到 UIView 类型的参数的不兼容指针类型

Question

我正在尝试使用MWPhotoBrowser创建一个带有故事板的照片库。我在第一个视图中添加了一个蓝色视图，但收到错误消息

CCD_ 2。

代码：

在.h文件中：

#import <Foundation/Foundation.h>
#import "RESideMenu.h"
#import "MWPhotoBrowser.h"

@interface DEMOSevenViewController : UIViewController<MWPhotoBrowserDelegate>
@property (nonatomic, strong) NSMutableArray *photos;
@property (nonatomic, strong) NSMutableArray *thumbs;
@property (strong, nonatomic) UIView *container;
- (IBAction)showMenu;
@end

在.m文件中：

#import "DEMOSevenViewController.h"
@interface DEMOSevenViewController ()
@end
@implementation DEMOSevenViewController

Answer 1

问题出在这里，您添加的是ViewController，而不是需要view的视图。

[_container addSubview:browser];

尝试：

[_container addSubview:browser.view];

此外，也不完全确定为什么要将它添加到NavigationController和_container中，这取决于可能会导致问题的代码的其余部分，但前面的事情是导致错误的原因。
