Load custom UIView with XIB from a View Controller's view using IB

由 China☆狼群 提交于 2020-01-12 07:58:30
问题 I have a custom UIView ( MyCustomUIView ) which is built using Interface Builder. I'd like to place this custom view in MyViewController 's view, which is also designed using IB. I've placed an UIView as a subview in MyViewController 's XIB and set it's class to MyCustomUIView . The problem is, when I run the code, only a blank view appears. (When I instantiate MyCustomUIView in code, it displays well.) I'm only overriding the initWithFrame: method the following way in MyCustomUIView.m : -

Objective-C iOS Development Using viewDidLoad or initWithCoder when setting Variables and Why?

由 ╄→尐↘猪︶ㄣ 提交于 2019-12-23 20:35:17
问题 So it seems like I should be setting my member variables in viewDidLoad - but I am confused as to why setting these variables in initWithCoder fails, since both are called at the start of the program. In particular I have a line of code: [worldView setMapType:MKMapTypeSatellite]; In which worldView is a IBOutlet MKMapView object. It works under viewDidLoad , but not initWithCoder . 回答1: The objects do not yet exist when initWithCoder is called, and they do when viewDidLoad is called. Check

XCode8 initWithCoder frame Size

问题 Found if use XCode 8 XIB file, the UIView initWithCoder will get frame (0, 0, 1000, 1000) instead of the XIB frame size setting. Check the diff of XIB xml file it will add <autoresizingMask key="autoresizingMask" flexibleMaxX="YES" flexibleMaxY="YES"/> and remove rect frame settings such as <rect key="frame" x="110" y="0.0" width="20" height="17"/> Removing rect frame setting is the major root cause to get width 1000 and height 1000 in the initWithCoder. Therefore, any related size

Why isn't initWithCoder initializing items correctly?

问题 I've got a subclass of UITableViewCell . My subclass contains several UILabel s. I want my subclass to initialize these labels to some default settings that applies to every table view cell of mine. I read that I should be using initWithCoder for this. My initWithCoder function is being called, and I can step through each line in my function and it appears to go through the motions. When I run my application I do not see any of the properties being applied, though. Most noticeably, the font

Objective C - Custom view and implementing init method?

由 北城余情 提交于 2019-11-27 10:45:23
I have a custom view that I want to be able to initialize both in-code and in nib . What's the correct way to write both initWithFrame and initWithCoder methods? They both share a block of code that is used for some initialization. The right thing to do in that case is to create another method containing the code that's common to both -initWithFrame: and -initWithCoder: , and then call that method from both -initWithFrame: and -initWithCoder: : - (void)commonInit { // do any initialization that's common to both -initWithFrame: // and -initWithCoder: in this method } - (id)initWithFrame:(CGRect
