Question

我想创建一个带有属性字符串的简单标签。我是这样做的：

NSDictionary *noNotificationsAttrs = [NSDictionary dictionaryWithObjectsAndKeys:centredStyle,
                                      NSParagraphStyleAttributeName,
                                      [NSFont fontWithName:@"Raleway-Bold" size:30],
                                      NSFontAttributeName,
                                      _grey,
                                      NSForegroundColorAttributeName,
                                      nil];
NSMutableAttributedString *noNotificationsString =
[[NSMutableAttributedString alloc] initWithString:@"No Notifications"
                                       attributes:noNotificationsAttrs];

NSTextField* title_field = [[NSTextField alloc] initWithFrame:
                             CGRectMake(
                                        0,
                                        0,
                                        200,
                                        200
                                        )
                             ];
[title_field setWantsLayer:true];
[title_field setSelectable:YES];
[title_field setAllowsEditingTextAttributes:true];
[title_field setAttributedStringValue:noNotificationsString];
[title_field setEditable:false];
[title_field setBordered:false];
title_field.tag = 1;

结果如下：

和

不幸的是，点击（选择）此标签时，它显示如下：

和

角落周围有点粗糙和像素化。这种情况正在发生，许多其他标签具有不同的字符串，大小和颜色。我该如何解决？！

请注意，这些标签嵌套在nsscrollview - ＆gt;内nstableview - ＆gt; viewForTableColumn

选择时叠加：

我相信问题是NSCell在mousedown上调用了一个编辑函数。

选择时字体也不同!!

有趣的是，如果我从（2）父视图中删除wantslayer:YES，它就不会这样做。但是他们都需要想要层，否则我就不能有弯角等等......

Answer 1

将此行添加到您的代码中。

curl -d 'info={ "EmployeeID": [ "1234567", "7654321" ], "Salary": true, "BonusPercentage": 10}' http://example.com/xyz/php/api/createjob.php

因此在选择时将属性添加到与窗口关联的NSTextView。

您现在所获得的内容，如选择后的粗体和字体更改将被覆盖。

工作代码

已将NSTextView *textEditor = (NSTextView *)[[[NSApplication sharedApplication] keyWindow] fieldEditor:YES forObject:title_field]; [textEditor setSelectedTextAttributes:noNotificationsAttrs];更改为NSForegroundColorAttributeName 和NSBackgroundColorAttributeName到_grey

[NSColor clearColor]

Answer 2

为了解决这个问题，我制作了一个自定义的NSTextField，在这里选择它更新如下：

While going in the project--> Configure--> set the path of the git correctly.
It should be till the bin and then append git.exe like *\bin\git.exe

但有时仍然很有趣

我已将其修复完美！希望对大家有帮助。

1.lazy property
- (NSTextField *)textFieldOne{
    if (!_textFieldOne) {
        _textFieldOne = ({
            NSTextField *view = [[NSTextField alloc]init];

            view.cell.scrollable = true;

            view.font = [NSFont fontWithName:@"PingFangSC-Light" size:14];
            view.cell.wraps = true;

            view.editable = false;
