1.Set view's Frame from a string.

example0: the beginning.

UIView *view1 = [[UIView alloc] init];

//usually
view1.frame = CGRectMake(20,20,40,20);

//now
view1.frame = [self.view jhRectFromString:@"[x:20,y:20,w:40,h:20]"];

example1: set view's width is half of ther screen.

UIView *view1 = [[UIView alloc] init];

//usually
view1.frame = CGRectMake(0,20,self.view.frame.size.width/2,20);

//now
view1.frame = [self.view jhRectFromString:@"[x:0,y:20,w:2_w(0),h:30]"];
//self.view's tag is 0.

example2: put view1 at the center of self.view.

//view1's width is 50,height is 50.
UIView *view1 = [[UIView alloc] init];

//usually
view1.frame = CGRectMake((self.view.frame.size.width - 50)/2,(self.view.frame.size.height - 50)/2,50,50);

//now
view1.frame = [self.view jhRectFromString:@"[x:2_w(0)-25,y:2_h(0)-25,w:50,h:50]"];

more methods, find yourself.

2.A quick method to set view's Property.

example0: view.

    UIView *view = [[UIView alloc] init];
    
    //usually
    view.frame = CGRectMake(20,40,50,30);
    view.backgroundColor = [UIColor redColor];
    view.layer.borderWidth = 2;
    view.layer.borderColor = [UIColor blueColor].CGColor;
    view.layer.cornerRadius = 5;
    view.layer.masksToBounds = YES;
    view.tag = 5;
    
    //now
    view
    .jh_addToView(self.view)
    .jh_frame(@"[x:20,y:40,w:50,h:30]")
    .jh_bgColor([UIColor redColor])
    .jh_bdWidth(@(2))
    .jh_bdColor([UIColor blueColor])
    .jh_cnRadius(@(5))
    .jh_mtBounds(@(YES))
    .jh_tag(@(5));
    

example1: label.

    UILabel *label = [[UILabel alloc] init];
    label
    .jh_addToView(self.view)
    .jh_frame(@[x:20,y:40,w:150,h:30]")
    .jh_text(@"label")
    .jh_color(@"0xa2s3f4")
    .jh_font(@"s15")
    .jh_bgColor(@"0xb1d10a")
    .jh_align(@(1))
    .jh_adjust(@(YES))
    .jh_lines(@(0))
    .jh_bdWidth(@(1))
    .jh_bdColor([UIColor blueColor])
    .jh_cnRadius(@(5))
    .jh_mtBounds(@(YES))
    .jh_tag(@(5));
    

example2: button.

    UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
    button
    .jh_addToView(self.view)
    .jh_frame(@"[x:20,y:80,w:150,h:30]")
    .jh_title(@"button")
    .jh_color(@"0x1a2b3c")
    .jh_bgColor(@"0xa1b2c3")
    .jh_cnRadius(@(5))
    .jh_font(@"s17")
    .jh_target_selector_event(self,@"jhButton",@(UIControlEventTouchUpInside));

notice: jh_addToView should be called before jh_frame.

• more support: textField,textView,tableView,scrollView.
• need more, do it yourself.
