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;
}
