ios - 线程1:断点5.1:不兼容的指针类型将'MWPhotoBrowser *'发送到类型UIView的参数

我正在尝试使用MWPhotoBrowser创建带有情节提要的照相馆。我在第一个视图中添加了蓝色视图，但收到错误消息

Thread 1:breakpoint 5.1:incompatible pointer types sending 'MWPhotoBrowser *' to parameter of type UIView。

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

最佳答案

问题在这里，您要添加ViewController而不是需要View的视图。

[_container addSubview:browser];

尝试：

[_container addSubview:browser.view];

同样，也不完全确定为什么要根据代码的其余部分将其添加到NavigationController和_container中，这也可能会导致问题，但是上一件事是导致错误的原因。
