UILabel设置内边距

Posted 2023-02-26

参考技术A CustomLabel.h

#import

@interface CustomLabel : UILabel

@property (nonatomic, assign) UIEdgeInsets textInsets; // 控制字体与控件边界的间隙

@end

CustomLabel.m

#import "CustomLabel.h"

@implementation CustomLabel

- (instancetype)init

if (self = [super init])

_textInsets = UIEdgeInsetsZero;



return self;



- (instancetype)initWithFrame:(CGRect)frame

if (self = [super initWithFrame:frame])

_textInsets = UIEdgeInsetsZero;



return self;



- (void)drawTextInRect:(CGRect)rect

[super drawTextInRect:UIEdgeInsetsInsetRect(rect, _textInsets)];



@end

Demo.m

CustomLabel *titleLabel    = [[CustomLabel alloc] initWithFrame:CGRectMake(0.0f, 0.0f, 100.f, 24.0f)];

titleLabel.backgroundColor = [UIColor whiteColor];

titleLabel.textColor      = [UIColor blackColor];

titleLabel.font            = [UIFont systemFontOfSize:12.0f];

titleLabel.textInsets      = UIEdgeInsetsMake(0.f, 15.f, 0.f, 0.f); // 设置左内边距
