一 聲明方法
#import@interface MyLodingView : UIView
+ (void)showLoadingWithAfterDelay:(NSTimeInterval)second superView:(UIView *)superView;
@end
二? 實現方法
#import "MyLodingView.h"
#define KScreenWidth [[UIScreen mainScreen]bounds].size.width
#define KScreenHeight [[UIScreen mainScreen]bounds].size.height
#define COLOR(R, G, B, A) [UIColor colorWithRed:R/255.0 green:G/255.0 blue:B/255.0 alpha:A]
@implementation MyLodingView
+ (void)showLoadingWithAfterDelay:(NSTimeInterval)second superView:(UIView *)superView
{
MyLodingView *myLodingView = [[MyLodingView alloc] initWithFrame:CGRectMake(KScreenWidth / 2 - 50 , KScreenHeight / 2 - 50, 100, 100)];
UIActivityIndicatorView *juhua = [[UIActivityIndicatorView alloc]initWithFrame:CGRectMake(0 , 0, 100, 100)];
juhua.backgroundColor = COLOR(81, 191, 156, 1);
juhua.layer.cornerRadius = 10;
juhua.activityIndicatorViewStyle = UIActivityIndicatorViewStyleWhiteLarge;
[juhua startAnimating];
UILabel *label =[[UILabel alloc]initWithFrame:CGRectMake(10, 70, 80,40)];
label.text = @"loading...";
label.font = [UIFont systemFontOfSize:13];
label.textColor = [UIColor whiteColor];
[juhua addSubview:label];
[myLodingView addSubview:juhua];
[superView addSubview:myLodingView];
[myLodingView performSelector:@selector(hideLoading:) withObject:juhua afterDelay:second];
}
// 自動消失菊花
- (void)hideLoading:(UIActivityIndicatorView *)juhua
{
[juhua stopAnimating];
[juhua removeFromSuperview];
}
