如何制作 UILabel 的弯曲文本 Objective c

How to make curved text of UILabel Objective c

我想制作 UILabel 的曲线文字。如何实现这个?

到目前为止我的标签代码是:

UILabel *loveLabel = [[UILabel alloc]init];
loveLabel.frame = CGRectMake(20, 50, 50, 50);
loveLabel.text = @"Flowers";
loveLabel.textAlignment = NSTextAlignmentCenter;
loveLabel.layer.cornerRadius = 25;
loveLabel.layer.masksToBounds = YES;
[self.view addSubview:loveLabel];
You can download a sample project that use CoreTextArcView:    

github

导入 "CoreTextArcView.h" 并在 viewdidload 中添加代码

CGRect rect1 = CGRectMake(0, 120, 320, 120);
UIFont * font1 = [UIFont fontWithName:@"Helvetica" size:26.0f];
UIColor * color1 = [UIColor whiteColor];
CoreTextArcView * cityLabel = [[[CoreTextArcView alloc] initWithFrame:rect1
                                                                font:font1
                                                                text:@"New York City"
                                                              radius:85
                                                             arcSize:110
                                                               color:color1] autorelease];
cityLabel.backgroundColor = [UIColor clearColor];


CGRect rect2 = CGRectMake(0, 235, 320, 200);
CoreTextArcView * cityLabel2 = [[[CoreTextArcView alloc] initWithFrame:rect2
                                                                 font:font1
                                                                 text:@"Google"
                                                               radius:-80
                                                              arcSize:-80
                                                                color:color1] autorelease];

[cityLabel2 showsLineMetrics];
cityLabel2.backgroundColor = [UIColor clearColor];

[self.view addSubview:cityLabel];
[self.view addSubview:cityLabel2];
