[英]UiLabel text assignment in custom view
I have created a custom view (custom view) inside other custom view(bage). 我在其他自定义视图(容器)内创建了一个自定义视图(自定义视图)。 Then in main view I add custom view as a subview.
然后在主视图中,将自定义视图添加为子视图。 After that I am trying to set text via property and it does not work.
在那之后,我试图通过属性设置文本,它不起作用。
#import <UIKit/UIKit.h>
@interface Bage : UIView
@property (nonatomic,strong) UILabel *title;
@end
#import "Bage.h"
@implementation Bage
@synthesize title;
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:CGRectMake(0, 0, 45, 25)];
if (self) {
// Initialization code
}
return self;
}
- (void)drawRect:(CGRect)rect
{
//// General Declarations
CGContextRef context = UIGraphicsGetCurrentContext();
//// Shadow Declarations
UIColor* shadow = UIColor.blackColor;
CGSize shadowOffset = CGSizeMake(3.1, 3.1);
CGFloat shadowBlurRadius = 3;
//// Variable Declarations
CGFloat buttonWidth = rect.size.width - 2 - 4;
CGFloat buttonHeigh = rect.size.height - 2 - 4;
//// Frames
// CGRect frame = CGRectMake(frSize.origin.x, frSize.origin.y, frSize.size.width, frSize.size.height);
//// Rectangle Drawing
UIBezierPath* rectanglePath = [UIBezierPath bezierPathWithRoundedRect: CGRectMake(1, 1, buttonWidth, buttonHeigh) cornerRadius: 8];

CGContextSetShadowWithColor(context, shadowOffset, shadowBlurRadius, [shadow CGColor]);
[UIColor.whiteColor setFill];
[rectanglePath fill];

rectanglePath.lineWidth = 1;
[rectanglePath stroke];
title = [[UILabel alloc] initWithFrame:CGRectMake(CGRectGetMinX(rect) + 1, CGRectGetMinY(rect) + 1, CGRectGetWidth(rect) - 6, CGRectGetHeight(rect) - 6)];
title.textColor = [UIColor blackColor];
title.textAlignment = NSTextAlignmentCenter;
[self addSubview:title];

Please help me to get text in my bage.
请帮助我在我的行李中输入文字。
Do not add the title as a subview in drawRect:. 不要在drawRect:中将标题添加为子视图。 You should do this when the Bage view is initialized.
初始化Bage视图时,应执行此操作。 Also, you are using the rect given to you in drawRect:, which will not always be the bounds of the view.
另外,您使用的是drawRect:中赋予的rect,它并不总是视图的边界。 So, add the title in your initializer
因此,在您的初始值设定项中添加标题
