简易 实现时间线 时间轴效果

##代码方式使用 JKProgressLine *lineCode=[[JKProgressLine alloc]initWithFrame:CGRectMake(100, 100, 8, 0)]; lineCode.edge = UIEdgeInsetsMake(40, 0, 40, 0); lineCode.items = @[@"tesbbrtt",@"哈34哈",@"12dftg3",@"12cvf3",@"134523"]; lineCode.itemWidth = 8; lineCode.itemMargin = 80; lineCode.doneColor = [UIColor colorWithRed:0.278 green:0.600 blue:0.227 alpha:1.000]; lineCode.selectColor = [UIColor colorWithRed:0.757 green:0.000 blue:0.141 alpha:1.000]; lineCode.normalColor = [UIColor colorWithWhite:0.480 alpha:0.600]; lineCode.selectedIndex = 3; [lineCode setTouchedLineBlock:^(NSInteger index, NSString *title) { NSLog(@"click%zd title%@",index,title);

}];
[self.view addSubview:lineCode];

##xib方式使用 @property (weak, nonatomic) IBOutlet JKProgressLine *line;

self.line.edge = UIEdgeInsetsMake(40, 0, 40, 0);
self.line.items = @[@"test",@"哈哈",@"122343",@"12df3",@"12sdf3"];
self.line.itemWidth = 8;
self.line.itemMargin = 80;
self.line.doneColor = [UIColor colorWithRed:0.278 green:0.600 blue:0.227 alpha:1.000];
self.line.selectColor = [UIColor colorWithRed:0.757 green:0.000 blue:0.141 alpha:1.000];
self.line.normalColor = [UIColor colorWithWhite:0.480 alpha:0.600];
self.line.selectedIndex = 3;
[self.line setTouchedLineBlock:^(NSInteger index, NSString *title) {
    NSLog(@"click%zd title%@",index,title);
}];
