我正在尝试自定义我的NSTextFields
,第一步是自定义placeholder
。
我想更改占位符的颜色,我以这种方式尝试了:
- (void)awakeFromNib {
// Color for placeholder in NSTextField - Color: #cdc9c1
NSColor *placeholderColor = [NSColor colorWithCalibratedRed:0.80f green:0.78f blue:0.75f alpha:1.0f];
NSDictionary *placeholderAttributeDict = [NSDictionary dictionaryWithObject:placeholderColor forKey:NSForegroundColorAttributeName];
NSAttributedString *emailPlaceholderString = [[NSAttributedString alloc] initWithString:@"Email" attributes:placeholderAttributeDict];
// NSAttributedString *passPlaceholderString = [[NSAttributedString alloc] initWithString:@"Password" attributes:placeholderAttributeDict];
// NSTextField Email attributes
[[self emailTextField] setDrawsBackground:NO];
[[self emailTextField] setBordered:NO];
[[[self emailTextField] cell] setPlaceholderAttributedString:emailPlaceholderString];
// NSTextField Password attributes
[[self passTextField] setDrawsBackground:NO];
[[self passTextField] setBordered:NO];
[[[self emailTextField] cell] setPlaceholderString:@"Password"];
}
您可能会看到,第一个NSTextField
中的第一个占位符是由我尝试指定颜色的NSAttributedString
建立的。第二个NSTextField
中的第二个占位符只是NSString
。
运行应用程序时,仅显示第二个NSTextField
。第一个不会出现在任何地方。
发生了什么事?
感谢高级。
您将两次设置同一emailTextfield ...
[[[self emailTextField] cell] setPlaceholderAttributedString:emailPlaceholderString];
[[[self emailTextField] cell] setPlaceholderString:@"Password"];
(这是解决问题的问题还是只是问题中的错误?)
