的UIView有UIImage的背景

Question

ü建設的UIView，並把圖像作爲視圖backgrond：

self.tmpView = [[UIView alloc] initWithFrame:CGRectMake(20, 70, 280, 295)]; 
self.tmpView.backgroundColor = [UIColor yellowColor]; 

self.tmpView.backgroundColor = [UIColor clearColor]; 
self.tmpView.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"CloseUPPicBG.png"]]; 

的問題是，現在theuiview是用黑色的角落。 我作爲背景放置的圖像是圓角的。

任何解決方案？

Answer 1

將圖像編輯爲不具有圓角，或者使角落後面的空間是某種其他顏色或圖像。

你在做什麼，然後說

View, be yellow. 
View, be clear. What's behind you? Nothing. Ok, be black. 
View, fill yourself with this image. 

查看正在考慮

Hmm... there's transparency in this image. 
Guess I should show whatever's behind me. Which is nothing... So black. 

Answer 2

self.tmpView.opaque = NO; 

可能的幫助。
