一些开发内容,做个备注
总有一些方便的开发方式或者通用的方法,还总记不住,老是去翻以前的项目,做个备份。(慢慢补充)
1、view控件加边框
profileImageButton = [UIButton buttonWithType:UIButtonTypeCustom];
[profileImageButton.layer setMasksToBounds:YES];
[profileImageButton.layer setCornerRadius:4.0]; //设置矩形四个圆角半径
[profileImageButton.layer setBorderWidth:1.0]; //边框宽度
CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB();
CGColorRef colorref = CGColorCreate(colorSpace,(CGFloat[]){225.0/255.0, 225.0/255.0, 225.0/255.0, 1.0 });
[profileImageButton.layer setBorderColor:colorref];//边框颜色
单独设置圆角
[iconImage.layer setCornerRadius:4.0];
[iconImage setClipsToBounds:YES];
2、时区返回格式为数字(-12—+12)
-(NSString *)getTimeZone{
NSString *zone = [[NSTimeZone systemTimeZone] description];//Europe/Berlin// America/New_York// Asia/Harbin
//这三个可以用来测试exp:NSString *zone = [[NSTimeZone timeZoneWithName:@”America/New_York”] description];
NSString *time = [[zone componentsSeparatedByString:@”offset “] objectAtIndex:1];
int inv = [time intValue];
int result = inv / (60 * 60);
if (result>0) {
return [NSString stringWithFormat:@”+%d”, result];
}
return [NSString stringWithFormat:@”%d”, result];
}
