我正在学习如何创建越狱调整。

我希望这只是一个简单的问题。我正在使用 Theos。

我有以下设置： -

OneView.h

#import <UIKit/UIKit.h>

@interface OneView : UIViewController

@end

======================================

OneView.m

#import "OneView.h"

@interface OneView ()

@end

@implementation OneView

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        [self setOpaque:NO];
    }
    return self;
}

@end

======================================

调整.xm

#import <UIKit/UIKit.h>
#include "OneView.h"

//此功能可以正常工作并编译

%new
-(void)createView:() {
        UIView *view11 = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 480, 272)];  
        view11.backgroundColor = [UIColor redColor];  
        [self.view addSubview:view11];
}
%end

//这不起作用它在我编译时会产生错误。

%new 
-(void)createOneView:() {
        OneView *view11 = [[OneView alloc] initWithFrame:CGRectMake(0, 0, 480, 272)];  
        view11.backgroundColor = [UIColor redColor];  
        [self.view addSubview:view11];
}
%end

======================================

错误

 Preprocessing Tweak.xm...
 Compiling Tweak.xm...
Tweak.xm:144:44: error: 

'OneView' may not respond to 'initWithFrame:' [-Werror]

        OneView *view11 = [[OneView alloc] initWithFrame:CGRectMake(0, 0, 480, 
272)];  
                           ~~~~~~~~~~~~~~~ ^
Tweak.xm:145:16: error: property 'backgroundColor' not found on object of type 'OneView *'
        view11.backgroundColor = [UIColor redColor];  
               ^
Tweak.xm:146:31: error: cannot initialize a parameter of type 'UIView *' with an lvalue of type 'OneView *'
        [self.view addSubview:view11];

It does not like initWithFrame! is this something to do with headers !

谢谢

继承 UIViewController 时出错（更新）

        OneView *view11 = [[OneView alloc] initWithFrame:CGRectMake(0, 0, 480, 272)];  
        view11.view.backgroundColor = [UIColor redColor];  
        [self.view addSubview:view11];

'OneView' 可能不响应 'initWithFrame:' [-Werror]

        OneView *view11 = [[OneView alloc] initWithFrame:CGRectMake(0, 0, 480, 
272)];

您将 OneView 设为 UIViewController 的子类：

@interface OneView : UIViewController

但是你必须让它成为 UIView 的子类：

@interface OneView : UIView

createOneView is a reserved method name and can't be redefined. Just change the name of it to something else that still makes sense to you as the programmer, and it should be fine!
