iOS菊花加载圈

自定制一个继承于UIView的类然后重写initWithFrame方法;如下

- (id)initWithFrame:(CGRect)frame

{

self = [super initWithFrame:frame];

if (self) {

// 菊花背景的大小

self.frame = CGRectMake(kWidth/2-50, KHeight/2-50, 100, 100);

// 菊花的背景色

self.backgroundColor = MYCOLOR;

self.layer.cornerRadius = 10;

// 菊花的颜色和格式（白色、白色大、灰色）

self.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;

// 在菊花下面添加文字

UILabel *label = [[UILabel alloc]initWithFrame:CGRectMake(10, 60, 80, 40)];

label.text = @"loading...";

label.font = [UIFont systemFontOfSize:14];

label.textAlignment = NSTextAlignmentCenter;

label.textColor = [UIColor whiteColor];

[self addSubview:label];

}

return  self;

}
