项目中的工具类
项目中我们一般需要新建一个工具类，用来实现一些项目中经常使用的功能，方便复用，这边我收集了一些自己经常使用的功能
1.添加文字提示框
+(void)showHubTipWithString:(NSString *)string offsetY:(CGFloat)y{
if (string && string.length > 0) {
dispatch_async(dispatch_get_main_queue(), ^{
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:[[UIApplication sharedApplication] keyWindow] animated:YES];
hud.mode = MBProgressHUDModeText;
hud.detailsLabel.font = [UIFont boldSystemFontOfSize:17.0];
hud.detailsLabel.text =string;
hud.margin = 20.f;
hud.offset=SPPoint(0, y);
hud.removeFromSuperViewOnHide = YES;
[hud hideAnimated:YES afterDelay:0.8];
});
}
}
2.添加加载提示框
+(MBProgressHUD*)showLoadingHubAddedTo:(UIView*)view{
MBProgressHUD *hud = [[MBProgressHUD alloc] initWithView:view];
hud.contentColor=[UIColor whiteColor];
hud.bezelView.backgroundColor=[UIColor colorWithWhite:0.1 alpha:1];
hud.mode = MBProgressHUDModeIndeterminate;
hud.detailsLabel.font=SPFont(17);
hud.minShowTime=2;
hud.userInteractionEnabled = YES;
hud.removeFromSuperViewOnHide = YES;
[view addSubview:hud];
return hud;
}
3.手机号验证
+(BOOL)validateMobile:(NSString*)mobile{
NSString*mobileRegex=@"^(1[123456789][0-9]{9}$)";
NSPredicate*mobileTest=[NSPredicate predicateWithFormat:@"SELF MATCHES %@",mobileRegex];
return [mobileTest evaluateWithObject:mobile];
}
4.密码验证
+(BOOL)validatePassword:(NSString*)password{
NSString*passwordRegex=@"^([a-zA-Z0-9]{6,12}$)";
NSPredicate*passwordTest=[NSPredicate predicateWithFormat:@"SELF MATCHES %@",passwordRegex];
return [passwordTest evaluateWithObject:password];
}
5.获取段落行高
+(CGFloat)GetCellHeightWithString:(NSString *)string width:(CGFloat)width attributes:(NSDictionary *)attributes{
CGRect sizestring = [string boundingRectWithSize:CGSizeMake(width,MAXFLOAT) options:
NSStringDrawingUsesLineFragmentOrigin| NSStringDrawingUsesFontLeading attributes:attributes context:nil];
return ceil(sizestring.size.height);
}
6.秒数到时间到转化
+(NSString*)changeNumberToTime:(NSInteger)number{
NSString*minute=[NSString stringWithFormat:@"%02ld",number%3600/60];
NSString*second=[NSString stringWithFormat:@"%02ld",number%60];
return [NSString stringWithFormat:@"%@:%@",minute,second];
}
