- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我现在在 GalleryScrollView.m 中只收到 1 个错误。我想我声明的图库按钮是错误的。
错误是:
Instance Method -initwithFrame:imageName:imgname not found
用这一行:
GalleryButton *btnAttachment = [[GalleryButton alloc] initWithFrame:CGRectMake(startX, startY, width, height) imageName:imgName];
我试过 - (void) removeAttachment:(GalleryButton *)button imageName;
但这似乎不起作用。下面是我的代码。
非常感谢任何评论或回答。
谢谢。

最佳答案
我认为您在这里面临的唯一问题是您没有声明您的 - (id) initWithFrame:(CGRect)frame imageName:(NSString *)imageName
方法。确保您已在头文件中声明此方法:GalleryButton.h
具有相同的 signature .
关于iphone - 错误实例方法-initwithFrame :imageName:imgname not found Objective-C,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/13341266/
我想了解 Ruby 方法 methods() 是如何工作的。 我尝试使用“ruby 方法”在 Google 上搜索,但这不是我需要的。 我也看过 ruby-doc.org,但我没有找到这种方法。
Test 方法 对指定的字符串执行一个正则表达式搜索,并返回一个 Boolean 值指示是否找到匹配的模式。 object.Test(string) 参数 object 必选项。总是一个
Replace 方法 替换在正则表达式查找中找到的文本。 object.Replace(string1, string2) 参数 object 必选项。总是一个 RegExp 对象的名称。
Raise 方法 生成运行时错误 object.Raise(number, source, description, helpfile, helpcontext) 参数 object 应为
Execute 方法 对指定的字符串执行正则表达式搜索。 object.Execute(string) 参数 object 必选项。总是一个 RegExp 对象的名称。 string
Clear 方法 清除 Err 对象的所有属性设置。 object.Clear object 应为 Err 对象的名称。 说明 在错误处理后,使用 Clear 显式地清除 Err 对象。此
CopyFile 方法 将一个或多个文件从某位置复制到另一位置。 object.CopyFile source, destination[, overwrite] 参数 object 必选
Copy 方法 将指定的文件或文件夹从某位置复制到另一位置。 object.Copy destination[, overwrite] 参数 object 必选项。应为 File 或 F
Close 方法 关闭打开的 TextStream 文件。 object.Close object 应为 TextStream 对象的名称。 说明 下面例子举例说明如何使用 Close 方
BuildPath 方法 向现有路径后添加名称。 object.BuildPath(path, name) 参数 object 必选项。应为 FileSystemObject 对象的名称
GetFolder 方法 返回与指定的路径中某文件夹相应的 Folder 对象。 object.GetFolder(folderspec) 参数 object 必选项。应为 FileSy
GetFileName 方法 返回指定路径(不是指定驱动器路径部分)的最后一个文件或文件夹。 object.GetFileName(pathspec) 参数 object 必选项。应为
GetFile 方法 返回与指定路径中某文件相应的 File 对象。 object.GetFile(filespec) 参数 object 必选项。应为 FileSystemObject
GetExtensionName 方法 返回字符串,该字符串包含路径最后一个组成部分的扩展名。 object.GetExtensionName(path) 参数 object 必选项。应
GetDriveName 方法 返回包含指定路径中驱动器名的字符串。 object.GetDriveName(path) 参数 object 必选项。应为 FileSystemObjec
GetDrive 方法 返回与指定的路径中驱动器相对应的 Drive 对象。 object.GetDrive drivespec 参数 object 必选项。应为 FileSystemO
GetBaseName 方法 返回字符串,其中包含文件的基本名 (不带扩展名), 或者提供的路径说明中的文件夹。 object.GetBaseName(path) 参数 object 必
GetAbsolutePathName 方法 从提供的指定路径中返回完整且含义明确的路径。 object.GetAbsolutePathName(pathspec) 参数 object
FolderExists 方法 如果指定的文件夹存在,则返回 True;否则返回 False。 object.FolderExists(folderspec) 参数 object 必选项
FileExists 方法 如果指定的文件存在返回 True;否则返回 False。 object.FileExists(filespec) 参数 object 必选项。应为 FileS
