how to show UI objects code in xcode? - xcode

Question

in one part of my project I need to create some UI objects programmatically, can I just customize my UI Objects like labels,... visually in storyboard then simply copy/paste generated code relevant to that object?
I searched in xcode menu but I couldn't find this but once I saw it in a tutorial in youtube.
Thanks in Advance

Yes you can customize the UI Classes or any other class, Like I have customize UILabel Class as UILabelExtended
UILabelExtended.h
#import <Foundation/Foundation.h>
/* **********************************************************************************************
This class inherit the class UILabel and extend the features of UILabel.
********************************************************************************************** */
#interface UILabelExtended : UILabel {
__unsafe_unretained id customDelegate;
id objectInfo;
SEL selector;
}
#property (nonatomic,assign) SEL selector;;
#property (nonatomic,assign) id customDelegate;
#property (nonatomic,retain) id objectInfo;
#end
#interface UILabel(UILabelCategory)
- (void)setHeightOfLabel;
- (void)setWidthOfLabel;
- (void)setHeightOfLabelWithMaxHeight:(float)maxHeight;
- (void)setWidthOfLabelWithMaxWidth:(float)maxWidth ;
#end
UILabelExtended.m
#import "UILabelExtended.h"
#implementation UILabelExtended
#synthesize selector,customDelegate, objectInfo;
- (void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
if(self.selector)
if([self.customDelegate respondsToSelector:self.selector]) {
[self.customDelegate performSelector:self.selector withObject:self];
return;
}
}
- (void)dealloc {
self.customDelegate = nil;
self.selector = NULL;
self.objectInfo = nil;
}
#end
#implementation UILabel(UILabelCategory)
- (void)setHeightOfLabel {
UILabel* label = self;
//get the height of label content
CGFloat height = [label.text sizeWithFont:label.font constrainedToSize:CGSizeMake(label.bounds.size.width, 99999) lineBreakMode:NSLineBreakByWordWrapping].height;
//set the frame according to calculated height
CGRect frame = label.frame;
if([label.text length] > 0) {
frame.size.height = height;
}
else {
frame.size.height = 0;
}
label.frame = frame;
}
- (void)setWidthOfLabel {
UILabel* label = self;
//get the height of label content
CGFloat width = [label.text sizeWithFont:label.font constrainedToSize:CGSizeMake(99999, label.bounds.size.height) lineBreakMode:NSLineBreakByWordWrapping].width;
//set the frame according to calculated height
CGRect frame = label.frame;
if([label.text length] > 0) {
frame.size.width = width+5;
}
else {
frame.size.width = 0;
}
label.frame = frame;
}
- (void)setHeightOfLabelWithMaxHeight:(float)maxHeight {
UILabel* label = self;
//get the height of label content
CGFloat height = [label.text sizeWithFont:label.font constrainedToSize:CGSizeMake(label.bounds.size.width, maxHeight) lineBreakMode:NSLineBreakByWordWrapping].height;
//set the frame according to calculated height
CGRect frame = label.frame;
if([label.text length] > 0) {
if (height > maxHeight) {
frame.size.height = maxHeight;
}
else {
frame.size.height = height;
}
}
else {
frame.size.height = 0;
}
label.frame = frame;
}
- (void)setWidthOfLabelWithMaxWidth:(float)maxWidth {
UILabel* label = self;
//get the height of label content
CGFloat width = [label.text sizeWithFont:label.font constrainedToSize:CGSizeMake(99999, label.bounds.size.height) lineBreakMode:NSLineBreakByWordWrapping].width;
//set the frame according to calculated height
CGRect frame = label.frame;
if([label.text length] > 0) {
if (width > maxWidth) {
frame.size.width = maxWidth;
}
else {
frame.size.width = width;
}
}
else {
frame.size.width = 0;
}
label.frame = frame;
}
